This is an informal lens test between two of my Favorite lenses, A late Collapsible Summicron that I CLA'd myself, and a 1957 Type I Rigid Summicron that I had professionally CLA'd. Both are very clean, and I think representative of their type.

This is not a test for absolute resolution of the lenses, but more of the rendition of the two pieces. These are as they came off of the scanner, and re-sized using photoshop. No post-scan processing for contrast or color balance.

First up: The Collapsible Summicron wide-open at F2.
