This lens is fairly blurry when shot wide open. For macro work it is okay. The bokeh is not bad, but I would not recommend shooting wide open with this lens. Having said that, there are not many 24mm photography vintage lenses with that kind of F stop. At T2.0 it is good, at T2.8 it is great. This lens can be used on Sony A7s i or ii and Canon 5d mk ii, which are full-frame sensors, and any sensor size smaller.
