adusting Bronica rf645 to use filters

[Zorkiiglaza]

Its been a while since I used filters on a non TTL metering camera.
I want to put a roll of b/w through my new to me RF645 and can't remember how to compensate the exposure when using filters ie: yellow, orange, or red?

The meter on the camera is next to the viewfinder, so it isn't affected by the filter and you have to use the compensation dial on the back. The filter factors are usually shown on the filters, for example, orange is around 4x. This would darken the image by 2 stops, so you would use +2 compensation on the dial (overexposure). The only exception to this is when you use the Bronica's polarizing filter with the small filter holder directly over the viewfinder.

Thanks Steve!
Yellow +1
Orange +2
Red +3
This is my 1st modern rangefinder- I've dealt with filters with vintage rangefinder cameras in the past. After testing, i might use a light yellow most of the time
thanks for the quick reply

Perry, this is correct. When you need more than the RF645 can give you in terms of compensation simply use the ISO dial. So if you're compensating +3 stops for a red filter dial +2 on the dial then take a stop away from your film speed (ex: ISO 400 to 200) and that equals +3.

Thanks a lot
In the past I usually used my meterless rangefinders ie: Leica, Zorki, Kiev, but now and again I want to use my SP35 or my Konica C35.
