Rob, I think the key here is to learn to love the UV/IR filters for doing a more thorough job of removal than the cover glass in other cameras... plus you have the option of taking the filter off if and when you want, say for black & white. The coder kit has not worked well for me either, so I just sucked it up and sent the lenses off to DAG for coding and focus-check. That solved that. Finally, look at the crop factor for its advantages in using those wide lenses that are troublesome with the M9 and M240, both for ditching the color edges and for solving the excess width! Hope you come to love your M8.2 more. 🙂
