Plenty sharp enough for the situations but it has a different look than when stopped down. Great lens. I also have the 40 ƒ1.4 Classic that is on a CL 99% of the time. Nice little lens that gets along well with the CL. The standard lens hood conflicts with the RF on the CL so I switched to a smaller, generic one. My 25mm Color-Skopar has served me well, a 50mm ƒ3.5 Heliar is a good performer and a little-used 75 ƒ2.5 does well enough. I thought the 75 might be more useful than the 90 Leica glass I have but neither gets much exercise.... That's the Voigtlander glass I have now and I can't say any have been disappointing at all.
