It seems like a matter of when, not if, Canon and Nikon will enter the high-end, full-frame mirrorless market. But will any system they release accommodate legacy lenses?Last week I wrote an article in which a supposed “internal document” from Fujifilm suggested Canon and Nikon will lose 50% of their market share within three years. Naturally, this created a lot of healthy discussion among Fstoppers members and the article has had almost 100 comments to date. Many of the issues brought up in the comments related to mirrorless systems and what will happen if and when Canon and Nikon enter the mirrorless market.
Currently, the likes of Sony, Fujifilm, and Olympus are at the forefront of the mirrorless market and have a good head start on the two traditional giants. However, it seems a foregone conclusion that both Canon and Nikon will produce a high-end mirrorless system sooner rather than later, perhaps as early as next year if rumors are to be believed.
But what drove a lot of discussion in the comments to last week’s article was whether or not any high-end mirrorless system that Canon or Nikon release will allow for full integration of legacy lenses that owners have been using on their DSLRs hitherto.
The Current Need for Adapters
At the moment, if you want to use DSLR lenses on a mirrorless system you need to use an adapter, such as the Metabones T Smart Adapter. That is simply to account for flange distance - the distance between where the lens mounts and where the sensor sits in your camera. Obviously, the distance is different when you compare a mirrorless system with a DSLR system that has a mirror, hence the need for an adapter.
Depending on the adapter you use, you might not be able to use automatic focus or auto aperture with your current lenses. Naturally, the adapters that couple legacy DSLR lenses with mirrorless systems most effectively are at the more expensive end of the market, and don’t always guarantee a perfect transition. Which brings us to our current dilemma.
When Canon or Nikon release a high-end mirrorless system into the market, will those cameras have the capacity to allow for perfect use of lenses currently used on DSLR systems? Now that might seem like a ridiculous question considering they are two completely different systems but I will put my hand up and say, perhaps naïvely, that I had assumed that the two makers would provide such a feature without a shadow of a doubt.
From a Business Perspective
I did some looking at it purely from a business perspective. If you look at Sony, for example, it has had its a7r series out for about five years and is now on its third iteration, the Sony a7riii. That means Canon has had almost five years to sit back and look at how developments have played out. During that time, the two traditional giants have seen a number of people move over to mirrorless systems, albeit with the need for them to use an adapter for their legacy lenses.
So in reality, that means that the likes Sony and Fujifilm are ahead of Canon and Nikon by about five years in their Research and Development for high-end mirrorless systems currently on the market. So surely, when Canon and Nikon do finally release a high-end, full-frame mirrorless system to compete with the current market leaders, it won’t just be something similar to what’s already available now with other brands? Surely it has to be something significantly better?
If it isn’t, don’t you think they risk alienating loyal users who have sat back and waited for them to release a system that competes with the likes of Sony, and hopefully outperforms them?
From a Personal Perspective
In my case, for instance, I have put years and years and thousands of dollars into building up my lens collection, mostly with Canon. I am perfectly happy with my current 5D Mark IV and batch of lenses, but of course, if I could use them all on a native Canon mirrorless system that was a significant improvement on my current camera, then of course I’d jump at the chance. However, if Canon releases a full-frame mirrorless system that still requires an adapter for legacy lenses and doesn’t guarantee full integration of all lens features, then I will have to think seriously about which way I go, for two reasons.
First, I’ll probably be angry that I’ve put so much time and effort and love into curating my current collection of lenses yet they may potentially become redundant on a new, mirrorless system. That's a sentiment that many people have expressed. You might say I could simply go out and buy an adapter but there is enough current evidence out there that they are not always successful and do not always guarantee seamless integration of all lens functions and features.
And it would be pure speculation at the moment as to the success of any adaptor because neither Canon nor Nikon have released a high-end mirrorless system. But if they did come out and release a full-frame mirrorless system with the caveat that I needed to start my lens collection again from scratch if I wanted to benefit from all the features of such a system, then I wouldn’t be a very happy camper. And it’s something I hadn’t even contemplated until last week.
Follow the Leaders
Secondly, if that scenario were to play out then I’d have to think seriously about following many others and moving over to a different brand. Why? Simply because of position in the market. If Canon, for example, released a full-frame mirrorless system that was essentially on par with the Sony a7riii and didn’t offer a significantly better experience, then why would I not go to the market leader?
You’d imagine the likes of Sony and Fujifilm and Olympus etc are already researching and designing upgrades for their next release. So if Canon couldn’t give me an irresistible reason to remain loyal (such as full integration of legacy lenses), then I’d be heavily tempted to go to a system that already has 1,000s of users and advocates and proof of worth, rather than hope that Canon’s first iteration was a blinding success (albeit potentially without use of my legacy lenses).
I put this issue to both Canon and Nikon on Twitter, but am yet to hear a response. This doesn’t mean anything really, but it would have been nice to get some information about what’s on the horizon.
How do you feel about it? Do you think Canon and Nikon will find a way to integrate legacy lenses with new, mirrorless systems, or do you think it’s a pipedream? And if you’re a Canon or Nikon owner, will you stay loyal if they release a mirrorless system that requires an adaptor to use legacy lenses, or will you jump to brands like Sony, or Fujifilm?
I’d love to hear your thoughts in the comments below.
Knowing Canon, they will probably give you as little as they think they can afford. Canon has shown that it won't give a screw more than it needs too and even if it needs too, they won't give it if it competes with their existing line-up.
Of course, the rest I am going to write is conjecture but it wouldn't surprise me if they released several MILCs (2 for instance) of which one was severely handicapped when using an adapter and the most expensive model will probably work well with an adapter. I am convinced that they won't go balls out but will give the bare minimum.
I am not a technical person but I have read on multiple sites that lenses made for d-slrs won't function that well directly on a mirrorless body. It had something to do with the focussing systems.
I think Nikon will go balls out to keep their clients. Canon have become complacent. They are still convinced everybody will stick with them.
Is there a reason they couldnt just copy sigmas style of mirrorless camera and just a normal flange built in and then there would be no need for an adapter and lenses would match up just fine
They could but I can't imagine they will. Too many people, who want a mirrorless camera, want the benefits inherent in a shorter flange. An adapter, until they make new lenses makes a lot more sense. Unless they're foolish (not to say they aren't) their adapters will be as good or better than currently out there.
Forgive my ignorance, but can someone explain the benefits that are inherent in a shorter flange distance? Is it just to make the body narrower?
A few benefits...

Thanks for the link. From reading that short discussion though, it seems the contributors aren't really sold on any supposed "benefits" of a shorter flange distance. Pros and cons
Yeah. Like anything else, your personal preferences inform the compromises you're willing to make.
Thanks for the link. Based on this information it doesn't really seem like that would be the main driving force for a new lens mount, but since Nikon has so many different AF variations of their F-mount, it makes sense to me that they would feel the need for a new design going forward. At some point you have to just move on. Canon users went through this when they went from FD to EF mount.
"At some point you have to just move on."
That probably depends on your needs. I don't care about mirrorless or a different mount but then, I'm older and more methodical in my photography. None of the benefits of mirrorless apply to me.
My comment was meant about the manufacturers that need to keep up with the latest technology. There are always exceptions. Some people still shoot film cameras. :-)
The real question as well is whether the benefits of mirrorless are THAT beneficial. To date, I just can't see it. I mean, if you stand 10 pro photog landscape/portrait/whatever pics taken by a variety of DSLRs and mirrorless systems next to each other, to the naked eye do you think most people will be able to instantly recognize the mirrorless shots? I highly doubt it.......
At this point, the differences between cameras isn't the resulting shot but how easily a particular camera helps the photographer *get* the shot, how comfortable the camera is to the photographer, how reliable the camera is, etc... Not unlike a mechanic's tools.
Interesting viewpoint. From my perspective the end result is the be all end all. Unless a camera is ergonomically ridiculous to use in my hands, I'm sure I can adapt my feel for it. In saying that, I'm only 5'7 and 63kg so size for my fingers doesn't really matter, but I know its a massive issue for bigger people with bigger hands and fingers.
I've been pondering that as well, along with the relative pros and cons.
I'd rather not use an adapter if I didn't have to, at the same time, perhaps they could integrate the adapter in a different way so that it's more secure.
Also, if you are still going to include a robust grip, how much space do you shave by removing the depth required by the standard mounts?
Seems to me like you don't necessarily need to use a different mount at all really. Other than looking weird, and a lot of other companies using new mounts, it doesn't necessarily seem like a necessity to use a new mount to me. The biggest drawback is you'd still have to build lenses around the larger flange distance, but I suppose you could modify that concept and have the lens extend further back beyond its physical mount more. You'd need some weird rear lenscaps to accommodate that kind of design.
These are all the exact same things I've pondered. And all your questions are ones that surely the smart people at Canon/Nikon have pondered too. Thus my belief that they surely, surely must come up with some kind of mount system that integrates current lenses well.
I don't think there is a significant clamor for a smaller body than a Rebel or a 7D. I sure don't want a smaller body. Lighter, fine...but if they come up with nifty new things to do with the space, it wouldn't bother me even to keep with the same weight.
Nor do I think Canon or Nikon has to duplicate Sony with different nameplates. I think they're going to continue developing features in their current directions, emphasizing their own particular strengths--i.e., the areas where they already own patents and Sony doesn't.
In that regard, when Canon does its thing, I think it's not going to be a separate mirrorless lineup, but a replacement of current models. If the rumor is true that Canon is about to announce vIII replacements for some of their current vII lenses, particularly the essential f2.8 70-200 L IS, in the ES mount, that strongly suggests there won't be any change in that aspect for another decade.
Funnily enough I own a Rebel (1st camera), 7D mkii (2nd camera) and 5D mkiv (3rd camera). I still use all of them in my classes and with my family and I have to be honest and say that whrn I have lenses attached to all of them (as one does when one takes photos), I can barely tell the difference between them. There's certainly no significant difference in weight, feel etc.....
I wonder (not having shot with one extensively) how much difference a mirrorless body really makes in terms of size/weight/bulk when it has a lens and adapter attached to it....
The reason to not do that is pretty simple: Why would you put your system at a disadvantage long term just to please a few professionals short term?
The short term hit they'd likely take might make it difficult for them to recover in the long term.....
Yes. In 1987 when Canon made the Big Bang change to the EF mount, they moved to a position of distinctly secure market position (there was only one major competitor) and that move to the EF mount put them a technological lightyear ahead of Nikon and every secondary competitor.
After several more years, when I finally gave up my manual focus FD system and looked to autofocus, Having to buy a totally new system, I was piqued enough at Canon to take a fresh look at Nikon (still the only major competitor for professionals)...and found Nikon's limping transition to autofocus a confusing mess. You needed a score card to figure out which Nikon bodies worked with which lenses and how integrally each combination functioned. Minolta had the headstart on autofocus, but didn't have a professional body or lens line. Leica was still pretending autofocus didn't exist.
So I stuck with Canon then...but only because there wasn't a really viable option, and Canon took a huge leap over Nikon--that's when you started seeing all those white lenses on sports sidelines.
Canon does not have that luxury today. Professionals aren't going to be thrilled about taking that kind of bath, nor, for that matter will most people with more than one lens. There will be a whole lot of people taking that opportunity to make sure some other manufacturer isn't offering something more...and unlike 1987, we've all heard that another manufacturer is.
Canon would be dumb as hell to orphan the EF mount. A really tight EF-to-M adapter sold with the lens might serve as an acceptable bridge, but abandoning current customers will likely sink them.
Does anyone have any experience with the EF EOS M adapter? I've read good reviews on it, but don't know anybody with an M camera body.
I have one, I don't put anything massive on it, but it's solid.
I agree completely, hence the article....
Personally I'd like to see a Leica SL style, larger body, with a proper grip, nicer materials than the sony's system (looking at you plastic LCD cover...), and then have lens mounts with the same lens contacts as the EF/F mounts, and then sell them all with a the first party adapter, giving users the versatility of mirrorless in terms of legacy lenses and more compact wide angle designs, while maintaining full compatibility with their existing lenses, to provide a smooth upgrade path for DSLR users that are still invested in their glass.
I hope that CaNikon releasing mirorless FF will make many people selling their gear at the same time so I can have all I need at a cheaper price than usual.
I understand this type of articles and I'm absolutely not against it, but I think it has not much to do with photography. I had the chance to meet a photographer I admire the other day and he still shoots a Canon 5DmkII that he's not planning to upgrade anytime soon, looking at his work you wouldn't care about what he's shooting with because that's not why his clients come to him anyway.
Absolutely true - the camera and lens are just tools in someone's hands. We can all pick up a pencil but we can't all draw beautifully. But if a FF mirrorless has significantly better quality in the finished product and is comparable/cheaper in price to current DSLR FF cameras, of course people will be interested.
Both firms have a tremendous incentive to make a big splash in mirrorless so having the conversion for the existing base as seamless as possible would seem to be all but mandatory.
Nikon's fan sites are rich with speculation/un-validated rumors of a new mount. As the the market #2, Nikon has less market power and a fully-functioning adapter would be all-but mandatory to make their offering attractive to the current base. On the other hand the F-mount right now -- unlike Canon's -- is a heterogeneous hodge-podge of incompatibilities with the less then three year-old AIS-P mount variants adding to the mix. So it would seem some incompatibilities are inevitable. Still, Nikon did it with their ill-fated Series 1 mount a decade ago.
Canon on the other hand has a huge choice: they could stick with the EF mount and offer truly effortless conversion but that means foregoing the flange-distance advantage on lens designs shorter than, say, 50mm. Still even if they had a new mount, a fully function and compatible adapter for the EF is vastly easier to engineer and produce than Nikon's options.
Overall i wouldn't be too worried about this issue. The real question about full frame mirrorless is: what are the advantages? There will be some (ha! no lens AF calibration!) but, as any full frame Sony user will tell you, total kit weight for equally-specced lenses is not one of them.
Yes I've written many times that when you factor in adapters and lenses and filters and filter holders added to bodies, there really isn't much difference in size/weight/bulk between DSLR/mirrorless. You raise many valid points and I hope the engineers at Canon (and Nikon) don't go the easy route and opt just for adapters.
Here's something I've never thought about before; Let's say both Canon and Nikon come out with a new mount/lens system. If that happens will standard lenses plummet in value? For the last 20 years lenses have held their value much better than cameras but this won't be the case if they both dump their standard mounts.
Maybe. Think about when they switched from FD to EOS, and then when IS was introduced, and then when digital sensors required higher resolving power (if you believe in that sort of thing). There are some lenses that will for sure hold (big white ones), but the other thing to consider, and why the values will hold for a while, is how long it would take for them to release all the equivalents in a new mount.
Well I don't know the market in the USA but in the Netherlands lots of lenses are being offered on the second hand sites, but most don't get any bids.
In the Nikon system, I can almost guarantee that D-series and any other older screw-driven AF lenses will not be compatible with the new mirrorless system for AF. It would just be way too complicated to try to put an AF motor in some sort of adapter, and I highly doubt that Nikon will natively build a screw AF into the mirrorless body. Even if some sort of adapter did exist, I'm sure it would be $800+ given the pricing of their battery grips right now.
Let's hope Canon keeps the same mount and body as the 5DMiv and Nikon uses a body similar to the D850. I have a A7Riii as well as the above and really can't see what all the mirrorless hype is all about. The buttons are all wrong and the grip doesn't fit with full frame lenes. Being small and light, you would think would make for a good walk around camera, but not. You can't leave it on or you will have an terrible time trying to figure out what settling got changed. You turn it on and off all the time.
John, your comment brings up another issue with full-frame mirrorless that, as non-Sony user, you cut to the heart of it. There are practical limits to how small a "pro" level body can be and meet two ergonomic requirements: 1) real-estate for the buttons we demand for quick adjustment; and 2) the laws of optics limit the ability to shrink lenses with a 22+mm image diagonal.
Actually, regarding the second point there is some savings for lenses shorter than, say, 50mm with the shorter flange distance requiring less extreme retro focus optical designs. Note though, that you do not get away entirely with that retro-focus need since the image corners have angle of incidence constraints.
Any the point is that kit weight for a large sensor-ed system is largely dominated by the optics not the body. The m4/3 "pro" bodies -- with immense attention to haptics -- show that their bodies grow to at least APSC dSLR size to be tractable, and that is with a vastly smaller sensor.
I know it's kind of apples and oranges but think about mobile phones. Remember how tiny they went about 10 years back? It was incredible. But then once more (and better) features were implemented, naturally the size increased in order to accommodate them.
As you've rightly pointed out, you can only go so small until it becomes completely impractical to even hold in your hands. I find it hard typing on my iphone keyboard now. I can barely imagine the frustration I'd feel trying to use one of those old tiny phones.....probably the same with the race for tiny mirrorless bodies....
So far, I really have not found a really good reason to switch to a mirror-less camera.
Neither have I. And I am sure that my D750 will continue to work well for years after Nikon releases a new mirror-less camera. So, I don't see all this urgency. I wouldn't buy another Sony product if they were the only game in town.
That is of course a personal question to all of us. I fell in love with the EVF the minute I discovered them.
I use reading glasses and I was fed up with chimping all the time (glasses off, take, picture, glasses on, chimp, glasses of, adjust). Plus that with the EVF my exposure is most of the time spot on because of the what you see is what you get.
Added to the fact that probably due to some issue with my eyes, I is easier for me to see sharp with an EVF. I don't know why.
Lastly, I had some rather nasty front and back focus issues with my d-slrs and mirrorless doesn't have that issue.
I never thought of those benefits. I still don't want one but it's good to know.
Interesting points. I wear glasses for long distances but for photography I'm still fine without glasses for the most part. Something to keep in mind.
Plus, if you shoot video, you can use the evf. That is very handy when shooting in very bright light. The viewfinder of my a6300 is hardly good for anything when shooting 4k in bright sunlight (it dims to a setting in which it is unusable in bright light) but the evf always works great.
Totally agree. For those of us 'optically challenged' a good EVF is a wonderful thing. The M5's actually lets me see more of the image and settings than my 5DmII does when I'm wearing glasses. Then again my 16 yr old son calls the M5 the blasphemy camera due to the EVF :-) (I brainwashed him early with film cameras)
the key for success in the mirrorless world for Canikon definitely is dependant on what solution their find for seamless integration of their current lens collection.
Moot question at the moment for me. I have no interest in going mirrorless. They are just too small.
Yeah, nice idea, but I had to turn buttons off because there wasn't room for my thumb.
This is a common issue for discussion. How small can you actually go before it becomes totally impractical. For some, it's already too small.
Ok, unpopular opinion here. It is absolutely absurd to think that the industry should stop innovating just because it's convenient for you. I don't care how many thousands of dollars you have invested into your system, the benefits over the long run of having curved sensors and smaller flange distances far outweigh the growing pain of switching to this superior system.
Is it superior? Looking at many of the responses here, I'm not so sure....
And is it not innovative to find a way to integrate current lenses and future lenses?
sigma is offering a mount conversion on some of the glass for about $150 I think I read ?
but at this point any new glass I get might just be that have two of their art lens the 50 and 135 both are insane good but do have a small bit of focus issues at times ? but think mirrorless will fix that ?
I want the 14mm faster lens and if I buy a art at least I have a chance of conversion
so to say I think sigma is on a good track here and if they could redo the mount on all art series for under $200 I think many on the fence like myself might look more at the art series as a option
I would expect Canon to find a way to make their older lenses work easily with any new mirrorless body. My EOS M5 works great with the Canon adapter and my EF lenses. I hope that the EF lenses will work on a full-frame body without adapters. If not, Canon will give customers a very good reason to changes systems, because using an adapter is quite inconvenient.
Now, where did I leave that adapter this time?
