What can I say, when choosing a lens in a store, I checked it mainly at close focusing distances, camera), it can hit the target, but not glass worth 57 thousand ! ating the firmware on the docking station did not help, I spent a couple of evenings with the adjustment on the docking station - the result was 0 I took it to the store under warranty, my advice to all who are looking closely at this glass is to check it in the store PERFECTLY! At all focusing distances on an open hole! There is a flash, take a flash, itβs better to spend half an hour in the store and either leave with high-quality glass, or go look for other options than spoiling your nerves first by adjusting, it is very strange, and very unpleasant to receive a picture of disgusting quality from the top glass,
