Hi all,

I am looking at an Asahi Pentax 6x7 in very reasonable but well used (not abused) working condition: it shows brassing on all corners and along some edges. The mirror is exceptionally clean and there is no obvious mould or rubbish in the viewfinder or elsewhere on the body. The asking price is acceptable (providing it all works).

It comes with an SMC Takumar 200/4 lens, which is also very clean inside, the diaphragm, focus ring all very smooth and all the click-stops and stop-down lever function well.

One problem: the TTL lightmeter seem to give/result in readings that (presumably) underexpose to hell ; e.g. for ISO 400 film in bright sun, it suggests about f/22 @ 1/1,000 (a long cry from f/16 @ 1/400? Is this something that could be fixed? (I've been assuming the camera.lens functions in open aperture metering, am I right?)

Second question: I see there are 6x7 SMC Takumar lenses and SMC 67 Pentax lenses: will the Asahi Pentas 6x7 accept the later(?) Pentax 67 lenses or not?

BTW, an image of the camera may be found here:

Thanks for responding

The meter should be calibrated.
Or, just adjust the ISO until it reads right.
The 6x7 will accept later lenses.

OK, thanks: good to know about the lenses.

You are suggesting that the meter can be "serviced"? That would be very good news.

Was I correct in assuming that "open aperture metering" is the proper thing with this camera/lens combination (SMC Pentax 200/4)?

Open aperture metering is correct.

Open aperture metering is correct.

Thanks.

It's looking good: the vendor is willing to service the metering.
