>>3005629I've had my Pro2 side by side with a 240. The 240 is a fat fuck but Leica's glass is really small for what it is, and the M10 is substantially thinner than the 240. Just look at pic related with the XP2 + 23 1.4 vs. the M10 + 35/2, setups which should be functionally very similar given the Leica's FF sensor vs. Fuji's APS-C.
The Leica is still noticeably smaller with a 35 1.4 if you want to match apertures, too.
