hello dear Community, I got a GM lens 35mm f1.4 recently and I shoot on Sony alpha R IV. I have had some weird results when I am shooting with this lens under low light situations. The picture shows vertical darker bars. Does anybody know why this is happening? I would not think that there is a problem with the lens (maybe just light conditions and shutter speed make that happen). But if someone knows pls let me know. Thank you!!! #FE 35mm F1.4 GM #Alpha 7R IV (a7RIV)
