Quote:As stated above, the Voigtlander 20mm f3.5 SL II N wil do well too, it is pretty sharp stopped down and at landscape distances. The Voigtlander performs better than tests have you believe, due to its astigmatism at close (MTF testing) distances.What's the source for this?
I've had Voigtländer SLII 40, 58 and SL90, all outstanding color, contrast and sharpness (very low CA). The 20 was not an interesting FL for me on Pentax APSc, and the more interesting SLII 28 was never offered in PK mount, alas so never tried the wider lenses. I also have the Cosina-made Zeiss 25/2.8 which is also outstanding...another lens that does not test well but produces great results.
