Spotmatic SP F Help

Hi, new to theforum and revisiting film photography after a 30 year hiatus. Recently aquired a spotmatic and bought a telezoom off Ebay. It's a one-touch auto lense. In-camera light meter doesn't work with this particular lense. Any help with this? Any work arounds? Do I buy a light meter, buy a different lense and chalk it up to experience?

The lense I bought is a Quantaray 80-200/3.5 one-touch Macro.

Thanks for any help you can offer.

Asking this in the film section will get you lots of answers.

Non SMC type lenses don't have the aperture sensor required for the SP-F to meter wide open. (The only compatible 3rd party lenses I know of are Adaptalls with an "ES" screw adaptall - this has a little gear to emulate the SMC lens mount)

But you can use your lens the old fashioned, stop-down way:
on the left side of the prism housing there is a stop-down/meter switch (as you're looking through the viewfinder)... Push it up to stop down the lens and start the meter. You do not need to meter every time you shoot of course.

Maybe I am missing something... sorry if so...

Press the metering swtich UP. That should give you stop down metering for any lens that is not open aperture compatible. You can confirm by chaning the f/stop and seeing the needle move. If it does not move, add/subtract shutter speed until it does.

Just, remember that the meter on the SP F is always on. Unlike the earlier Spotmatic and Spotmatic II, the switch on the side of the lens mount only operates the aperture for DOF preview or stop-down metering.

It is imperative that you put a lens cap on when the camera is not in use.
