I know this is somewhat off-topic but i thought i might be able to sneak it in. So, here goes: I just bought a camera with a 52mm thread, but I already have a filter that is only 49mm. And I'm planning to buy two more filters for my camera. 1) Is it possible to use a 49mm filter (with a downstep for the threads) on a 52mm camera? Or would you see the edges of it in your picture? 2) What is more common? 52mm or 49mm?
Any advice is greatly appreciated.
