I'd say it's not nesessary to code a 35 mm lens for M8. I've never seen any cyan corners on my M8 with it, but some with the 28/2.
The wider the lens; the worse the problem. 35 mm is sort of on the boarder.

I once tested various 35s, including both 35 Cron ASPH and 35 Lux ASPH, and the Lux needed coding wide open. The Cron could get by without.
That's very wierd since the filter is infront of the lens, not behind it. For an M9 it would make sense though, because of different rear nodal points of the lenses and the filter being on the sensor. Or are you only referring to vignetting, not cyan corners?
Cyan corners. The 35 Lux collects light from a larger area, which apparently made a difference. It sounds a bit weird, but I saw it clearly, again and again. The thread is here, in case you would like to read it:
