Collapsible Summicron and Type I Rigid Summicron Comparison Shots

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.

Just one more Comparison! Not on the same roll, this is with a 1935 Uncoated Summar at F2:

 

YES! You can make any modern film look like Kodachrome 10! Can anyone doubt that there is a special quality to these lenses, designed WITHOUT the aid of a computer?

Thank you for this interesting test. Yes, the Summar is a beauty. Unfortunately, very sensbible to flare. But a good coated Summar could do a very good job indeed.

However, the judgement of lenses in black and white is quite different.

This is what I did with the 50mm collapsible Summicron whide open:

Wow like a Paint!!  Contrast is amazing, light is fluid, and the back scene is blowing my eyes!!!!  There is something about the way they used to built lens it is a good example for the art of the craftsmanship....a bit different from the today mass production made in China !
