This is from www.lenstip.com.

It also seem to beat the Nikkor on coma flare, lateral and longitudinal CA. "Worse" wrt. vignetting though.

Sten, this is indeed quite an impressive performance by the Sigma 35mm f/1.4 lens in the 1.4 to 2.0 range.

Hm. The report states clearly the Sigma does not deliver the same kind of buttery smooth bokeh as the Nikon (and Canon) equivalents. So again, one has to determine the planned usage of the lens before rushing out to get one. Sharpness alone, good as it may be, is not always the prime factor of importance.

I purchased my AFS 35/1.4 solely because of its bokeh and superb handling of spot-light sources.The "drawing" of the image by this lens is special in the smooth way the sharp portion of the frame fades into the unsharp background. It'll be interesting to compare the rendition from the Sigma on similar subjects.

It may be that the Sigma engineers over-corrected the optics in order to boost resolution at the expense of smooth (less "perfect" optically) OOF area.

all nikkor fast primes suffer greatly from CA (on the d800
with the 50/1.4g leading the bunch)
and their oof rendering is sweet

...one might ask exactly what the point is of an f/1.4 lens if the bokeh is not excellent. if the focus was obtaining an absolutely sharp image over the entire frame, you'd be shooting at a much smaller aperture and the size, weight, and cost of the f/1.4 lens is wasted.

if indeed these designs are the result of necessary optical compromises, i'll take better OOF rendition for a little less sharpness at f/1.4 and f/2.0!

This picture from Lloyd Chambers blog shows awful bokeh - look at that jagged background. I'd trade a bit of sharpness for smoother rendition any day...

really awful. it has that jittery double vision thing going on.

i suppose the real question is whether decent bokeh is worth the $700 (?) difference between this and the 35/1.4g....

The Nikkor 35mm 1.4 is high on my wish list and my thought was at first when it came out that it would be in the same category as the 85mm 1.4 but what i have read so far i am not totally convinced about the gem this lens is and the price you pay for it.
It would be ideal for the way i photograph (street,landscape) very curious to read what my fellow Nikongearers have to say about the Nikkor 35mm who own a copy did it fill the expectations you had about this lens?

Marco.

with the AFS 35/1.4 it is the LoCA that puts me off wide open. From f/2.0 on, I am pleased with the Zeiss.

Sigma's reputation for highly variable quality control vs Nikon's reputation for very good quality control--D800 notwithstanding--does cause one to stop and think.

That may have been the case a long time ago, but I don't think it is the case anymore. When I get lenses from Sigma to evaluate they come in sealed boxes as brand new items. I haven't been disappointed with any of their offerings in recent times.

I'll see about getting one of these for a test run.

Also remember that Sigma operate on the cutting edge of optical design. Many of their lenses don't have any Nikon or Canon counterparts (eg, 12-24mm full frame, 120-300mm 2. 8). I don't know what the design of this particular lens is but it might be very different to the Nikkor's design, which would explain why the bokeh in those pictures looks so bad.

It's never a good idea to base one's judgement on a lens from only one sample image, especially when the lens in question can be tweaked by USB.

Dallas, do you know when those USBs will be available to tweak the lens?
I hope the software will be Mac compatible...
Thanks
