I was very upset by this purchase. I hoped that I would learn to work with him, that maybe he was not as bad as it seemed at the beginning. Until I got a Sigma macro camera and almost at the same price. photo, a good approximation and there is no such crop. And the brightness of the photo does not suffer. In general, I will take sigma, and this is a miracle in the far corner. If you are interested, there is a photo on my page.
