Lens Cap Filter
I have a 50mm lens. Why do my filters and lens cap say 55mm?
help!
Why do my filters and lens cap say 55mm when they fit on my 50mm lens.
The 50mm on your lens refers to it's focal length, ie the distance from the lens to the camera's focal plane, the 55mm refers do the diameter of the screw thread on your filters and lens cap or lens hood.
The lens I use mostly on my Canon 40D is a 25mm to 75mm zoom lens (focal length range), but the filters and cap etc. are still 55mm.
