So here are some tests with the Contarex Biogon 21mm f4.5. I\'ve never seen anyone post any samples from this lens before, these might be the first NEX shots ever with this lens...
Sorry for the boring subjects, but I haven\'t had time to get out and shoot. Performance seems very good, with superb overall sharpness, a hint of purple corners, and smeared extreme corners in some situations, close to zero distortion.
All at f8, as that\'s where the lens is stuck. I\'m sending it in for an overhaul next week, which besides fixing the aperture, might boost performance in other areas.
