Wow...I am learning a lot here...and I'd like to thank you again for being so helpful. Your honest, intelligent assessments have given me some food for thought.
Thanks :-). Honestly I like this place a lot more now that the Smite button is gone. <grin>
I have the Zeiss 21mm and would not give it up for another.
Yep, I understand completely. I've owned a lot of Zeiss glass:
- 50mm f/1.4 Planar (C/Y mount, adapted)
- 28mm f/2.8 Distagon (C/Y mount, adapted)
- 35mm f/1.4 Distagon (C/Y mount, adapted)
- 50mm f/1.4 Planar (native ZE mount)
Zeiss has a very different drawing style than Canon and emphasizes different aspects (e.g. microcontrast) that make the images seem more "alive". Congrats on that 21, it's great investment. Most reviewers conclude that it's one of the best wide-angle SLR optics on the planet, full stop. If you ever have to sell it you'll probably get fairly close to what you put into it. Certainly it won't depreciate with age.
I use a Sigma 50mm f/1.4....
Another nice lens. I feel it's a bit big & heavy for a 50mm, but then on a 5D it probably balances better.
Obviously, I am considering a 28mm for my Mark III....and I have yet to read an inspiring review of ANY 28mm...
Well, to tide yourself over maybe you should go pick up a new 40mm Canon pancake. I'm grabbing one as soon as I get paid again. The bang-for-buck factor on that thing is amazing.
Personally I really like Distagons a lot. I currently use an adapted 35mm f/1.4 as the "normal" lens for my 40D. I gave that 28 to my brother for Christmas last year, & he's done some great stuff with it so far.
I assume that if you've already got the 16-35 II and you're looking for a 28mm, it's either because you want something smaller or you're unhappy with the performance of the 16-35.
If it's a performance problem, you might check your autofocus calibration
on it. Also, read through the reviews
of the lens & check if the things that bother you were noted in the review. If you seem to have unique problems, then it's either a focus calibration issue or you truly have a bad copy.
give the Zeiss 28mm f/2 a lot of praise, but mark it down a bit for the field curvature issue. Evidently it's not too bad & unless you really need sharp corners it's probably not a showstopper. I agree that a $1k lens shoudn't have this issue though, espeically a Zeiss. In my case, the curvature is almost certainly completely outside the APS-C frame, so I'd been considering one...
