well i took 5 minutes to write about it but the MODs seem to have removed my totally fine reply.

again in short: the nikkor has a worse vignetting when shooting raw.
see photozone for more info.

yes you can not compare a MTF cart of a telephoto to a wide angle lens.

a good telephoto lenses will always look better in MTF charts (without this massive drop on the borders) then a good wide angle lens.

you have to compare lenses of the same class (telephoto to telephoto… wide angle to wide angle).

thought… 35mm is not really “wide angle”, but you get the picture i guess.

and with this in mind, the sigma looks very good (on paper).

ThePope2012: Thank you for your clarification. An apology and you are absolutely right, they do look very impressive compared to the Canon EF 35mm f/1.4L, and by a large margin!

I guess I was looking at it on face value and not relative to the Canon. I’m still not impressed with the drop off, but I guess this cannot be helped by the lens being somewhat wide.

you should learn to read an MTF chart before talking about it!!

sigmas MTF charts are for f1.4 … that means wide open.
unlike canon who shows f8 too.

so go to photozone and compare the EF 35mm f1.4 L with the sgima.

info: the black lines in the canon chart are for wide open aperture.

if you have .. come back and apologize… :)

sigmas MTF chart IS IMPRESSIVE!!

Comparing with the Nikon 1.4 charrts: 3220113009.jpg AND the EV drop off chart: vignetting.png it’s not a bad lens. the 35 1.4 drops earlier on MTF charts if I’m correct and the 2.1 EV loss is pretty similar (2 EV is 2 stops so 1/2 of 1/2 light = 25% right?? ;)).

What business decisions stopped them from upping their quality assurance sooner?

I know that Ronkinon 35/1.4 out preforms the Nikon version. But Rokinon is MF only. But then again, so is Zeiss. Im wondering how this will compare with the new Rokinon 35 lens.

Can’t wait to see a comparison between this, the Canon 35 f/1.4 L, and Canon 35 f/2 IS. I’ve had my eye on a 35 f/1.4 L for a while, can’t wait to see what Sigma delivers with this and then the refreshed 120-300 f/2.8

Mtf chart does NOT look impressive, in fact it falls off from the centre pretty soon (10mm), and the corner resolution seems quite low(0.5)! Why are they touting this less as such improvements, I feel it’s just marketing. The outer shell design is obviously very attractive, but I feel nothing more. If the MTF charts were better, this would be a steal at $900 at f/1.4.

I think I’ll wait for samples before I make too many assumptions!

Wow the new lens lineup looks gorgeous!
Can’t wait for the reviews to see if it performs!
