Okay as I promised I finally got the Pentax 67ii 2 weeks ago and have been trying it out.
I borrowed a lens from a friend of mine who has the pentax 6x7 MLU version. With his 80mm f/2.8 I put it through it's paces. Even before loading a roll of film, I already encountered a problem - the ISO film speed lever doesn't work. Pressing on the ISO speed button causes the ISO word to blink on the LCD screen, but fiddling with the ISO lever to adjust the value (stucked at 400) does nothing at all.
All is not lost, because it so happens I prefer to shoot at ISO 400. But still the ebay listing mentioned everything was working. A short email later and I either send it back to the US or I bring it to the nearest repair guy to fix it and they instead will reimburse me for the repair cost. Long story short, I'm having it sent to Pentax in Japan to be fixed and I'll go over there in November to pick it up, thus avoiding the Malaysian custom fingers from taxing me again for a 2nd time (They already taxed me 10% the first time).
Anyway, aside from the issue the camera is in good working order. Metering is accurate (tested with spot meter) and film loading and shutters fires nicely as verified after running a roll through it.
Now my personal opinion, this thing is DANG LOUD AND HEAVY! It cannot be used for street shooting, I'm not strong enough. I'll leave that to my GF670. It is more suited for studio shooting but I think it's annoying there is no flash amount and requires the weird wooden grip for it. Still at least I can attach a flash command via the PC sync port (haven't tried it out yet).
Overall, good for my purpose of studio shooting. Now onward for a good lens!
