The VC color-skopar 21mm f4 also punches way above it's class
I second this and concur strongly. I have the VC 21mm f/4 LTM Color-Skopar as well. Beyond it's great utility of being able to be used on both LTM and M bodies with an adapter ring, it is shockingly sharp and contrasty.
One does have to watch to ensure you get a clean copy. Some of the older Color-Skopars develop a haze that etches the inside of the glass and cannot be removed. Hence, it's best to buy one with full return/refund privileges and get it home for a flashlight test.
The other thing is you really want to get one with the matching lens hood. Buying it separately will cost you half again the cost of the lens. DAMHIKT.
I find myself crawling up to the subject more with this lens plugged into the camera:
