At least with Canon and Nikon versions of the lens the USB dock is available to tweak front/back focus at various focal lengths.
I agree, the USB dock will help considerably with various AF issues. But the dock itself isn't a cheap item.

DigiDirect will let you pre-order it for 717 AUD and I think it is the lowest out here. Pre-ordered mine here.

Since I don't own a current APS-C format Canon camera my impressions are on the 7D my student was using: The lens is certainly heavy, it balances rather well on a Canon DSLR - Pentax cameras tend to be a bit smaller in certain places and I can sense this may be a bit problematic with current pentax ergonomics
I agree with this statement...a friend of mine has a 7D and that is a big em effin crop sensor camera!
It's kind of silly, because she is such a tiny little asian girl, and i am this giant big guy, and my K-5+DA70mm was dwarved by her 7D + 24-105mm L. It would look a lot more natural if we had switched rigs

The only problem with 1.8 is... its 1.8!!! In practical application, it is difficult to get spot on focus (moving subjects) due to the focus plane. In a still life environment this will not be an issue. It is amazing that they are able to get so much light into this zoom lens! Also, 18-35 is a limited range for me. 18mm is fairly wide, but not too wide. 35 mm is a decent zoom, but not very close. I think most people will find this lens is limited in actual use, but there will be a few who have been waiting for a lens like this. I personally would like to see (in a perfect world) 16-55 WR. As long as this lens was at least f4 I would buy it!

anyways, just my thoughts on the subject

This is the internet; reality is elsewhere.

These photos are from the DCWatch photo review of the lens on a Sigma body:
It's worth noting that the SD1 is a very big camera; it dwarfs the K-5, and it's even a little bigger than a 7D. This lens is really the perfect companion for Sigma's own DSLR, since it needs all the light it can get, and small size was obviously never a priority.



Compare camera dimensions side by side

Mmm would that be a stupid idea?
When set up to do so, a camera could stop down a lens to a predefined lens-specific aperture value to operate AF and go back to nominal open value when AF done? (or not). Of course AF@3.5 and shoot@1.8 is asking for problems but this could still be a helpful tool when you use bright lens for e.g. viewfinder brightness.

In LiveView/Video it wouldn't even bother the viewing at all.

What about the lens I want? The NEW Sigma 30 1.4 ART lens. Has anyone heard if it will be available for Pentax? Besides the other improvements in lens quality (mainly the focus improves dramatically in the corners when you stop down as is usual for lenses) we will gain the quiet focus that was missing from the previous Sigma 30.

Is the price between the 35 and the new 30 so high?
If not, why chose the 30 if you can get the 35 ? Volume considerations maybe?

the 35 is intimidatingly big and heavy but oh so sharp.

Thankfully that lens will never be available in pentax K mount - the only option now is the 35mm f/1.4 which is optically superior to the current 30mm f/1.4 ART in just about every way.

Reports I have read from users of the current sigma 30mm f/1.4 state that the upgrade really isn't worth it - the lens still has the atrocious corner softness issues the original sigma 30mm f/1.4 had.

Mmm and it got the Art sticker? If all true, first real stupid thing Sigma did in quite a while.

Digitalis,

At the Lensrentals blog they tested 8 copies of the Sigma 30 1.4 art and compared it to 6 copies of the previous Sigma 30 and the new Sigma 35 1.4 art (which they rave about as you do). Note, however, they make a more balanced assessment of the differences in quality. More many Pentax is about compact lenses. For many the FOV of the 30mm is a better choice.

On a separate matter, Digitalis, would you prefer the new Sigma 35 to the Pentax FA 31?

Conclusion
Like a lot of people, I was hoping for a crop-sensor version of the Sigma 35mm f/1.4 full-frame lens; an amazingly high-resolution optic. This lens isn’t that good optically. It’s a very nice lens with good resolution and excellent corner performance. If corner performance is important to you this lens is a significant upgrade. If you are more interested in center resolution, than optically it’s not better than the original.
However, I’d still consider this a worthwhile upgrade for a number of reasons. Build quality is far better. The new lens can be accurately focused manually, something that live-view shooters like myself found was difficult to do with the original. I can’t speak for autofocus accuracy yet, but the Sigma USB dock,which now has a release date of early May, will allow us a degree of microfocus adjustment not available with other lenses. The dock is fully compatible with the A1 lens. To me, that’s worth the price of the upgrade right there.
