First of all, I want to thank Johan for starting this thread and also thank each poster for the images and discussions. This is a great thread for research purposes as I have been looking for as much information on the Summar as possible.😎
Secondly, I am late to the party, but have just received a 1937 Summar for my M3! 😀What an eye-opener...never used a collapsible lens before.
So, I am working through a roll of Portra 160 to see what the lens does and how I can use it. After that, I probably will work with a roll of TMAX 400. TriX after that.
Shooting with the Summar is absolutely a hoot!😛
