For Sale; Miranda P-AF 36 flash dedicated to Pentax AF film cameras with TTL metering. It specifically mentions the SF-7 & SFXN but it works with the Z-1 and I presume with other AF film SLRs with TTL flash metering.

GN 36m @ ISO 100 with bounce & zoom head & AF illuminator.

Can it measure the flash needed for an accurate exposure when bouncing the light off a ceiling?

It relies on the cameras TTL flash sensor during exposure (it doesn't have it's own sensor - like the Pentax AF240FT etc). So it will measure bounced flash correctly if the camera supports TTL flash. Not sure if it works jn TTL mode on a manual focus body.

I've also found the box and wide-angle diffuser for it.

Do you happen to know the trigger voltage? I'd hate to fry my *istD !

I googled for the voltage and couldn't find anything, My understanding is that most flash guns prior to the digital age, have high trigger voltages that will fry the electronics of digital camera's, I'd play safe and use a separate trigger to fire it. They can be found on fleabay for 15 ish

Sending PM. As I intend to use it on film cameras I don't need to worry about trigger voltages. It'll be nice to have a flash that will allow bouncing with TTL on film.

FYI, I found this website (for a sold one) which states it's only for the early Pentax AF film SLRS and not for any other models. I don't know if that's due to TTL functionality or a high trigger voltage.

*Update:* This has now been reserved.

I've put my DVM across the earth & centre pin contacts, I get somewhere around +3v with the gun charged - dropping to 0v as the flash is triggered. This was a kind of surprise and I can not verify this test is meaningful and wouldn't recommend using it on a digital camera (it's pointless anyway on anything that doesn't support 'old school' TTL flash).

Trigger voltages before electronic cameras were very high (I have a Vivitar 283 that exceeds 270v), at some point it dropped to 'reasonable' levels (either when dedication or AF came in). I don't know whether this is below the 5v range you might expect for a digital camera or in the 10-15v range. I expect many AF film SLRs are equally susceptible to high trigger voltages, the difference is that today, very few of them hold a significant value compared to a DSLR.

The comment about the early AF SLRs relates to the likes of the SFX, and *ist which have a sensor on the film plane. The *istD and the *istDS are the only DSLRs that also have this sensor. The *istDS enjoys the best of both worlds, using TTL and PTTL.
(If Jonathan doesn't take it then I will please).
