the chase for a 90

[Krosya]

... and who says that the Leica CL sucks for low light??!?!?! All shot with a CL and Elmarit 90mm stopped down to 2.8.. Shot at 1/15 second

Unless it was your intention here and in Web pics its difficult to tell, but these photos don't look like you got focus spot-on. Could be a slow shutter speed, but could also be a shorter RF base of CL. I have sharper photos from IIIf and M3 using Nikon 85/2 and J-9 at 1/15 sec. Just my opinion.
