First Spotmatic Question

Hello,

Just received my first Spotmatic, a SP F. I do have some S-M-C Takumar lenses around but none of my 35mm (my favorite) are capable of open-aperture metering on SP F. How should I use these lenses? My two 35s are Super Takumar and Mamiya Sekor 35 lenses, both of them have stop-down pins.

Push up the switch on the side of the mirror box to stop down meter.

Does this apply to preset lenses too?

My very first camera was a Spotmatic (not a SP-F), so I grew up on stop down metering. On the Spottie, the switch has two functions: it stops the lens down and it turns on the meter. On the SP-F, it only stops the lens down.

On my Spottie, which was not capable of open-aperture metering, I used preset lenses a lot, party because they were cheaper and partly because I had to stop down to meter anyway.

What I did with my preset lenses was to set the aperture to its smallest setting, usually f/16 or f/22, and leave it there.

I then simply used the stop down ring to find the correct exposure and then trip the shutter. This means that I often took pictures at odd settings like f/4.7 or f/8.3, as there were no detents on the stop-down ring.

One important thing to note about the Spotmatic-F. The meter is ALWAYS ON. So, a lens cap is imperative. Otherwise the meter will drain between uses. If you store the camera without a lens, use a body cap.
