Nota bene, the spherical 35 Summicron has two more diaphragm blades than the aspherical. Perhaps one of our more optically sophisticated correspondents could explain if this is responsible in any way for the different characteristics of these lenses.

Tamura Sent: Saturday, August 02, 2003 3:36 PM To: leica-users@mejac.palo-alto.ca.us Subject: [Leica] Summicron-M 35mm Question This has been bothering me for a while. I notice that the aperture in my 35mm Summicron-M (last model before ASPH) could open more at the F/2 setting. While looking from the front, it doesn't look "round" or completely open. Is that normal? Feel free to e-mail me directly at ttamura@aloha.net TIA, Thomas - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
