I've tried to test this lens with and without an UV filter, to see if there would be any degradation in IQ. Turned out there was none. But, I've found a much bigger problem.Apparently my lens shifts focus at higher f-stops.Both images are taken at f/...

I use AUTO2 setting for my EVF and LV usage.However, since I never press my eye to the VF, the camera switches to LV quite frequently. It's almost like I have to constantly be sure that the EVF sensor is covered. That can be quite frustrating while w...

I'm still using the one from 2018 that I got from 5DMKIV, since it has a retractable plug and I dislike power chords that came with other chargers from newer Canon cameras.The batteries are charged normally, but I'm wondering is there any harm by cha...

Hm, strange. I'm not aware if this option is different in other R cameras. On R7, the aperture ring is basically ever-present in E. Sim + DOF. But it does come with a cost, as I pointed out. If there weren't any, I would just use that option and be d...

Well, it doesn't matter where is the focus point as this happens even on a manual focus.So to recap, here what happens:- Focus is on the subject. In this case, a round box with small letters. AF is disabled. Focus remains, the camera is on a tripod.-...
