I’ve been mounting “non-standard” lenses on my cameras for years. Ever since I discovered that I could put M42 lenses on Nikon and Canon bodies I was hooked. Many older lenses offer a look and feeling that you simply can’t get with more modern “perfect” glass.
But deciphering photographs on the computer by searching through EXIF isn’t easy, because such lenses don’t communicate with the camera, so don’t store that lens information. This new cross-platform app, NameThatLens by Georg Fiedler wants to help solve that problem by allowing you to inject custom lens metadata into your images through a nice cross-platform graphical interface.
