I tested it when I bought it: the specimen was very successful in terms of sharpness. Focus is normal. They scared a little HA on an open hole, but this is still a feature of the model, not an instance! When buying, I was very afraid to be deceived in expectations during practical use, and not during testing. The very first session left behind uncertainty and doubts. I was struck by the softness of the picture, some brevity and completeness. The transitions in the blur zone just made me fall in love with him from the first day! I smeared the focus a little out of habit (very small flu - focused on the central point). Now I choose the nearest focus point and move the device to the minimum - a matter of habit. The focusing speed both indoors and outdoors is quite high, but loses 24-70, 24-105, 50 1,4. For the first time I didnβt have time for the child - now I got used to it! But it should be noted tenacity on contrasting objects, including in dim lighting! The picture gives an indescribable impression and allows you to make a real work of art out of an ordinary frame. Color rendition and microcontrast are on top - photos do not require any processing - there is simply nothing to improve! A hole (it's just a bottomless hole) allows you to embody all creative ideas - a truly creative lens! Once again, I note such a pleasant softness in the blur zone, regardless of the objects that have fallen. I shoot on 5D mark II - the optimal focal length for a portrait (from full-length to facial). I donβt even remember about money after use - itβs worth the money if you want to get the best and an extra ten will not make the weather!
