Nice. I have the 24mm f2.8 G and the 55mm.
As you know I had the Voigtlander 40mm f1.2 but now have the 35 and 50mm versions.
I don't think 40mm is a good fit for me now and it is of course even closer to the 35mm f2.8 I have so buying one maybe makes even less sense than buying the 50mm. The different build of the G lenses and their aperture rings compared the old 35mm f2.8 aren't big enough reasons for me in themselves. Another thing is that every time I use a 55mm lens I'm a bit irritated that it's 55 and not 50mm so the 50mm G could potentially replace the ocd triggering as it's ever so slightly tighter/longer than 50mm 55mm f1.8.
40mm is where I started (actually with 43mm) but these days after spending so much time with 35, 40, 50 and 55mm lenses of those I think 35 feels better for me as a usual first option with occasional uses for a 50/55mm rather than the piggy in the middle 40mm which may be ocd triggeringly close to 35mm and not able to replace a 50mm when 50mm is preferrable to 35 or 40mm. Of course I'd adjust in time though.
Decisions.
Mainly though this is just gas as I haven't bought anything for weeks
