Is the Sony a7 IV Worth the Upgrade Over the a7 III?

The Sony a7 IV has generally been met with positive reviews, with most praising its nice balance of photo and video capabilities. That being said, the a7 III is widely regarded as one of the most impressive hybrid cameras in recent history, particularly at its price point. So, is the a7 IV worth the upgrade, or should you save your money? This great video review takes a look at both cameras to answer that question. 

Coming to you from The Hybrid Shooter, this excellent video comparison looks at the Sony a7 III and a7 IV mirrorless cameras to decide if the latter is worth the upgrade. I was a huge fan of the a7 III when I reviewed it, particularly since it was such a good value for the wide features and capabilities it offered. That being said, the a7 IV certainly ups the ante a bit. Most notable to me is the nearly 40% bump in resolution. While the 24 megapixels offered in the a7 III were perfectly acceptable, 33 megapixels of resolution starts to get into that higher-resolution territory where you really have a ton of compositional freedom in post, and that can be quite freeing depending on what you shoot. Both cameras are quite capable, though, and should satisfy the needs of most creatives. Check out the video above for the rundown on both options.

there is an incremental benefit to each of the upgrades in this camera
there may be enough of a reason to buy the 'NEWST' when you're next in the market for a camera

but to ditch one for the other, there would have to be a real compelling reason

it's not there

The bump in linear resolution is 7000/6000 = 16%. The a7iii is $2k @ B&H now, and the a7iv is $2500 - so it’s a 25% bump. I hope I answered the OP’s question. Just stick to your a7iii and save money for a good lens.
PS. If someone needs a real bump in resolution - there’s a much better option - the a7rIV.

No, misinterpreting the significance of no less than one difference, whilst ignoring everything else except for the price definitely didn't answer OP's question. Try harder.

Really? Did you even read the article?
"*Most notable* to me is the nearly 40% bump in resolution."

Really. Images are two dimensional, so comparing "linear resolution" as you call it, makes no sense. 24*0.4=9.6; 9.6+24=33.6 what he wrote is correct.
By your "logic", A7 IV should cost $2800, although comparing two cameras based on a single specification whilst ignoring all other improvements of A7 IV, makes no sense either.

It doesn't make sense for you but it does for everybody else. Nobody would ever notice any difference while looking at a 7008 x 4672 image vs 6000 x 4000 image. Both will be displayed just fine on a 4k monitor and both will be short on an 8k monitor. Both can be printed on a billboard. A camera that offers 1/15s readout speed in 2022 is a joke. It would be a great camera in 2013 though. If someone already has an a7iii they would benefit MUCH more if they just buy a decent lens.

Again, I'm not sure if you read the article or if you understand what does "most notable" mean? For the OP the resolution "upgrade" is most notable, but it is actually irrelevant, and I explained why. If someone is in the market for a low-end FF Sony camera - they can consider the A7iv or they can buy the A7iii and put $500 towards a lens. "Upgrading" from the A7iii as the title suggests? LOL NO.

That is just your opinion (and your misinterpretation). I disagree. There definitely is 40% increase in resolution, that is not a matter of opinion. It seems that it doesn't make sense to "everybody else" either, since the A7 IV is the best selling camera nowadays.
I know that most "most notable" doesn't mean "the only upgrade". There are multiple reasons to upgrade to A7 IV, as explained in the video above.

The "best selling camera" according to who? What is percentage of the A7iii users buying the A7iv? Did you make a marketing research? What the A7iv can do that A7iii can't? I'd love to see your photo examples.

According to the best selling cameras lists of various retailers. I am an author of the video posted above, so you can find my photo examples and learn about more important difference between A7 III and A7 IV there :)

I didn't realize you are the author, sorry :) I'm aware of the technical specs of both cameras, and all marketing BS aside my opinion is the A7iv is one of the least exciting Sony releases of the decade.

William Svrček's picture

No problem :) I have actually addressed that in the video. There aren't that many headline improvements such as the increase of resolution, 4K 10-bit 4:2:2, 4K 60p or new AF features, but other features such as better IBIS, better EVF, new menu system and improved handling, stills / video switch, focus breathing compensation, dual UHS-II slots, digital microphone interface, properly working full size HDMI, much better display and so on make a big difference when combined.
Paying just $500 extra over the A7 III is a no-brainier. If you already have A7 III, it depends on the expectations and usage.
