Filter Size
Q. Do lenses with bigger filter sizes have an advantage over smaller ones? For example, does a 50mm f/1.4 with a 77mm filter size allow more light to pass through than a 50mm f/1.4 with a 58mm filter size?
A. Nope. The real issue is vignetting. If a filter frame is too deep, it may cut off the corners of the image, particularly at wide focal lengths. This is why wide-angle lenses often have filter rings much wider than the front element. Low-profile filter models will counteract vignetting. Stacking filters? Step-up adapter rings let you mount larger-diameter filters.
