Jack, I am really sorry to hear that. I don't like the filter option either, but considering the corner sharpness of the M8 vs. 5D and other cameras, I am happy with this compromise. I am also pretty sure that a new firmware and colour profile will minimise the IR problem. I hope you decide for an M8 sometime in the future.

Wrt. the focusing, that is just a question of practice. I miss focus as often with AF as I do with MF, due to moving subjects, recomposing, AF inaccuracy on my 5D, and so on. And your kit size comparison is not right. The 5D kit would weigh about 1kg more. Besides, the Canon 28 and 50 lenses are quite mediocre, whereas the Leica ones are some of the best in the world. Anyway, I am sure you know all this already.
