I took the first copy in the store, there were no complaints about the accuracy of focusing, I did not require adjustments in the camera. For me, it was also a big plus that the diameter of the thread for the light filter is 72 mm, there are already light filters of this size. When choosing between the first version and the second, I would recommend the second without a doubt. If you change the first to the second, then the decision should be very balanced :)
