Thanks, just quick shots with f4 and f 5.6 (from memory, as not recorded in exif). It does render lovely OOF areas at lower f stops. But as it is telephoto it helps to have distance between the subject and the backdrop. For some reason I can't get the 645Z and this combo to work with mirror up. Sounds like the the mirror or the lense activates, but no delay for second activation or sonic beeping to indicate two stage mirror up. Also no image recorded when the it 'fires'

Later update…..FYI, just tried my 67 165LS with 67-645 Fotodiox adapter on the 645Z in MU mode....works fine at all apertures and speeds.......bleep counter works to indicate stage 2 MU, shutter fires as normal, image recorded fine, and playback as normal.....????

Thanks for trying it out. It is a mystery. Actually it does work for 1 in a 100 attempts. I hope someone who knows about these things can determine the cause. Maybe letting me know here or on the other thread I started.

Bad contact(s)?

I have cleaned all the contacts. There is actually only one between the lens and adaptor and technically none between camera and adaptor. If only the adaptor is on the camera the mirror up functions 100%. But with the lens on it is hit and miss, mostly miss.

If there is no electrical contact between adapter and camera, how does the camera 'know' that the lens is mounted to the adapter so that the camera can fail to operate correctly? It would seem that the only 'connection' between lens and camera is the turning moment that the lens weight induces through the adapter to the camera flange.

Ten minute exposure above the Blue Lagoon at Abvereiddy...

The camera side of the adaptor has no metal pin contacts whatsoever. It could be that it is a connector in itself in it's entirety. It is connecting a 67lens to a 645Z and it doesn't support 'auto' anything. It is fully manual. There is only one connector pin on the lens that protrudes when the lens is set to auto, and connects to a pin on the adaptor at the lens mount interface. As the adaptor body makes contact with all of the camera contact pins perhaps there is some 'contact' made, but it isn't via a specific connector pin on the adaptor camera side.

Looks somehow surrealistic ... if now a spaceship would appear - nice!
