But there are variables to consider such as the ambient lighting, flash, available light, sunlight, contribution of vignetting. If I were shooting in available, tungsten light I would use the filter as the magenta cast would be most prominent. With flash and in sunlight I might take the filter off. If I shoot film I will probably take the filter off. I plan on testing for the cyan shift with the 21mm, 24mm, 35mm and up with and without the filters. I have the UV/IR filters for all these lenses. I just need the time to do it. I also want to be as accurate as I can. That's why I only mentioned the 21mm lens. I will not speculate on what Leica can do with firmware and coded lenses.
