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