Hi guys, anyone experienced when using cpl filter it change the focus of ur lens?
I just send my Sigma 70-300 for calibration, im very happy on the focus but yesterday when i tried using it with cpl ( a cheap one ) i got a blurred pics and even I checked on LV the subject is OOF. When I changed it back with UV filter the focus is just fine, so I suspect its because of the cpl filter. Does cheaper filters affect the lens focus?
