Originally posted by desertscape The 300 Takumar, when used on a tripod can be a pain. It is very susceptible to shutter vibration when shooting in the 1/2 to 1/30 second range. Handheld at 1/125 sec it does well. Putting extension tubes on it when on a tripod invites shutter vib because it now overhangs even more from the camera. If you are shooting like this but in the 1 second or longer range, not a problem. ...Or if you are using fast film and fast shutter speeds, no problem. The 300 Takumar rarely fringes, as it is well color corrected.
I have been to the Schwarzwald.
why are you shooting at such slow shutter speeds?with my 300mm i only shoot from a tripod or monopod, my shutter speeds run from 1/500 to 1/1000 sec. OOPS, SORRY i'm usenig the 645d so i can up the iso.
