I am seeing some very strange results using an old Takumar 50mm lens with a 4/3 adapter and am wondering if I am doing something very wrong. The problems is this: With the lense wide open, f1.4, the shots look pretty good though about +1EV helps. As soon as I start stopping down the lens, the images get really dark and need a minimum of 2EV to be even close to exposed correctly. I was under the impression that if the camera was put in the aperature priority mode (A), and the lens in the manual stopped down mode, the camera would adjust the shutter speed and get a correct exposure. This does not seem to be working. There isn't a lot said about this in the manual and all the articles I've read about using old glass on m4/3 cameras indicate that using the aperature priority mode is the way to go. The only other setting I am aware of is the 'shoot with lens off' setting, which is on. Anybody have any ideas what I am doing wrong? 50mm f8 +1EV View attachment 3983 50mm f1.4 +1EV View attachment 3984 These shots were taken at a diliberatley very high ISO.
