When I attach the 8 inch (20 cm) lens extension cable, I see more noise in the video, in the form of random white or pink pixels flashing on various parts of the screen. The video is still usable, but the issue is just something I noticed. When I remove the extension cable, video looks normal again.
For anyone else who has tried the 8 inch extension cable, are you seeing the same behavior?
I understand longer extension cables will naturally introduce more noise and artifacts, but I would like to confirm whether the degree of noise I am seeing is expected and normal. Or if I should try a replacement cable.
I captured some video samples to show the difference, but unfortunately, YouTube processing smoothed out many of the flashing pixels. You can still sort of see it, but the issue is more obvious in the original file format. Try viewing both videos in full screen, 1080p, and 0.25x playback speed. Look for the flashing pixels (or lack thereof) on the black backpack and orange couch background.
