A: While you can use other 52mm screw-in filters, Canon Drop-In Screw Filter Holder 52 (WIII) with Protector Filter B&H # CA52WIIIF not just any 52mm filter will do. The actual width of the filter is the deciding factor measurement, not the filter thread. Unfortunately, filter manufacturers do not list that number. The best hint we have is the fact the Canon protective filter is 54mm wide and about 5mm high. At this time, reports suggest that the B+W 52mm filters fit. Here is one.
