Canon EF 35mm f/2 Test Report . Released back in 1990 the Canon EF 35mm f/2 is one of the Methusalems in the current EOS lens line-up. It's a moderate wide-angle on full-frame cameras whereas on APS-C DSLRs it behaves a little bit more like a standard lens with a field-of-view equivalent to about 56mm. Canon EF 35mm f/2 Test Report:
The lens extends a little when focusing towards closer distances but the front element does not rotate so using a polarizer is no problem. The lens performed better than the EF 35 f/2 that it was replacing, especially noticeable in the corners. While center resolution remains about the same. They compared the lens against the original EF 35 f/2, the EF 35 f/1.4L, and Sigma 35 f/1.4. The real winner here appears to be the Sigma 35 f/1.4.
