- The main advantages are known - sharp, accurate, reliable, etc. • HA are minimal, visible only on the open in extreme double; • soft bokeh at all holes and distances, no scales, only cream; • the contrast on the open is slightly weaker than 50/1.8g, on the covered ones it is slightly stronger; • transitions are soft, lights/shadows without dips; • wide ring with a large angle of rotation; • constructive, ergonomics and materials are better than many branded glasses;
- • uncertain work of AF on non-cross sensors incl. in live-view; • AF is slower than 50/1.8g and much slower than screwdriver fixes; • AF misses already in room lighting, and when using the backlight from the speedlight - back focus (with a built-in standard lamp); • slight ultramarine color-shift on the open;
