Quote:Regarding the ability of the various consumer optics firms, I would rate them something like the following:
1. Zeiss - EUV litho and medical division for their aggressive utilization of freeform and aspheric optics
2. ARRI - same reasons
3. Canon - they seem to be miracle workers re: price/performance (10-18 stm etc) and also capable of very radical designs (11-24)
4. Leica - Excellent use of aspheres, very good to excellent performance in extremely small sizes
5/6. Zeiss (ZE/Milvus/FE/etc) - not as good as they used to be but still offering top-notch lenses
5/6. Sigma - very good lenses of late
7. Nikon - They're this far down for by and large being too conservative in the last decade+. Simple lenses, average/good performance, expensive, not particularly small.
8. Schneider - very good lenses, but extremely long development times. Give a man 4 years to design a lens and almost anyone could produce something great by chance.
9. Tamron - I may be being overly punitive because of sloppy construction on many/most lenses, but they have some excellent models like the new 35 and 45mm lenses in that regard.
10-xx Sony, Olympus, Panasonic, Fuji et al - I would never purchase a lens from any of these companies. 16% distortion in some models is simply inexcusable, very bad assembly quality, poor mechanics, and not particularly great performance out of any of them.
Interesting, thanks. Where does VoigtlÃ¤nder and Pentax fit in that list?
This ranking of lens design, or design+execution?
