How did your 40mm Nokton work after servicing? I mostly used mine with film and there it was excellent. But on the Leica M(240) at wider apertures there was corner smearing and color shading. I suspect it's the compact design that just isn't optimum for digital sensors. Interestingly the 40mm Rokkor did much better on the 240.Took my 40mm 1.4 Voigtlander to a tech guy and some of the internals were loose (and the 35mm had lens separation...grrr). Will wait and see what the VC 40mm performance will be after the repair. It is nice small and light so it could be a good solution...
