Dear Photo nutters :-)
I have a 1D (1.3X) and want to buy a wide angle lens for it. Ideally the lens would be rectilinear, FF compatible and have AF. However, all these are of less importance. What fears me most is flare. I live in Israel and it is very sunny. For example, the typical noon temperatures in the past week were ~25 degrees Celsius. Therefore, the sun is shining brightly and that makes flare a major problem.
1. The lens must be 15mm to 17mm.
2. It must have a Canon EF mount but adapters are O.K. by me. That means that a Nikon MF lens (for example) will do just fine. That also means that Canon FD (for example) are off the scope.
3. If it's an MF lens then I must be able to meter at Av or M. That means that Nikon G lenses (for example) are off the scope either.
4. It can't be too pricey (~700$ max) so all the east German exotic stuff is also off the scope.
5. If it will be a fish-eye, the images will be straightened later in software. I understand that this will decrease resolution in the edges. Pity but I can live with that.
6. Original lens hood will be used at all times.
7. Aperture will typically be f/8-11 so sharpness wide open is not a consideration.
8. I also consider APS-C lenses as know they will work without vignetting at these focal lengths. EF-ing the 10-22 USM is also considered. I know that it will work well from 12mm and up. The same goes for the Sigma 10-20. Tokina's 12-24 is good from ~15mm.
9. The prime/zoom issue is not important. I suppose primes will be better in that regard but if someone will suggest with a zoom with great flare resistance I won't mind :-)
I talked with Mark Welsh and he recommended the Tokina 17/3.5. That surprised me a bit because I was under the impression that Tokina lenses are not that great in that regard but as he has a lot of experience, I respect his opinion. BTW, do you know what is the difference between the old ATX version and the new ATX PRO version?
So, what do you think? Which is the most flare resistant ultra-wide lens?
