Hi all,
If you have a flash exposure meter, you can try the following test, I
always use this method to check the shutter speed of my OMs and it also
works with my Bronica SQ-A. I just tested my Olympus 35SP with this setup,
the shutter is very accurate from 1/2s to 1/250s (only +0.2 stop at 1/250,
all others are within +/-0.1 stop). At 1/500s the shutter is -0.2 from
1/250, it means the actual speed is only 1/250s. The Seiko shutter is
really good even it is 30 years old.
