Experience of use - over 5 years. It turned out to be a very controversial device. I don't even know how to rate it. Definitely, it doesnโt pull on the ideal, 3 points seem to be not enough, and 4 is a lot. Somewhere in between. The functionality is rich, ergonomics are at an acceptable level, autofocus of 20 lenses can be adjusted individually. So I had to adjust mine: one in plus, the other in minus. But the strong noise in the photo is depressing. Therefore, each, even despite the minimum possible ISO, to one degree or another must be processed in the editor in order to get a decent result. There is a built-in four-stage noise reduction, but on the first stage it does not cope with its task, and I didnโt raise it anymore so as not to lose detail. So I don't know, I don't know. A very controversial device . Because of this, the score came out halfway.
