| Pros: | Extremely well-made precision instrument, well-baffled | | Cons: | None | |
Necessary to use P67 lenses on the 645Z. Permits autoexposure in Av mode.

Came stuck with a 67 55/4 for a very good price from Japan. Separated them and repaired it, now works like a charm on my 645N.

| Pros: | Full automatic functions | | Cons: | Release button - it is a bit fuzzy | |
I've used it a lot with my non-autofocus 645 bodies. It works perfectly and exposure was always correct. Shooting with 90mm lens on 645 is very close to a standard lens FOV. It is very convinent to keep only 67 lenses and use 645 body as backup camera. Some examples about crop factor here.

| Pros: | build quality, sturdyness | | Cons: | price, lens release a bit hard to manipulate | |
Super quality and a perfect fit. I can only give it a 9, though, as the price new is quite steep.

| Pros: | Stable, nice anti-reflective finish | | Cons: | Durability of the button to release lens | |
This provides conversion from 67 mount lens to 645 body including digital bodies (i.e. 645D or 645Z). The built quality is fancy and finish is good; the finish inside gives minimum reflection and thus reduction of contrast.
I remember original instruction advises that M* 400 and M* 800 should not be used at full aperture since it might cause vignetting; these lens should be stopped down 1-stop. Digital camera should be less problematic since both 645D and 645Z has smaller sensor size compared to 645 film; thus vignetting cannot be seen; actually, I have M* 400 and 645D, have tested at full aperture, found no problem at all. Maybe I simply didn't notice vignetting though I would say you can use full stop with this combination. M* 800 might cause a problem even with digital camera, but I simply have no idea.
One thing I would suggest Pentax is to change the structure of the button to remove lens; this internally has a mechanism to convert direction of movements; one is parallel to optical axis and the other is perpendicular to that. The conversion is done by a tiny metal plate being bent after a while which is a problematic. If you are skillful, fortunately, this piece of metal could be modified so that it becomes functionally correct. You simply need to take off three screws on the side of the adapter, carefully open (so that the piece wouldn't be lost) and put the piece, modify, tighten the screw; that's it. I don't think Pentax changes this as 67 lens has been discontinued in 2008, thus selling 67 - 645 adapter doesn't make sense (however, this adapter is still available at least in Japan and is assembled in Vietnam; so I would guess Pentax is still making this product).
In the used market, most of them are made in Japan (they say "JAPAN" below the red dot used when mounting on 645 camera), but there is one assembled in Vietnam (they say "ASSEMBLED IN VIETNAM" at the opposite side of red/white dots). The built quality is identical though the color of the font (PENTAX ADAPTER...) is slightly different; the finish (black paint outside) is a bit different as well. I'd prefer one made in Japan, but it is true that those copies have been used for a long time and you might need maintenance (as described above). Any question regarding to this adapter is welcome; please do not hesitate to send me a message.

| Pros: | build quality, super easy handling, fits perfect | | Cons: | none | |
I bought it at eBay and came without caps.
There isn't much new to say: The adapter is a used item but nonetheless of wonderful condition, fits perfectly to my 645N and is easy to remove again – both, from the camera and the 67 lens.

These adaptors are great using P67 lenses on 645D cameras. If i could afford it , i would buy one for every 67 lens i own to reduce all the changing in the field. I have three now and they both are the best lens adaptors i have ever used.

Excellent for your sharp 67 lenses. I tried out 100mm Macro, 45mm and 75mm - all stunning.

Well made and light. Works with the Pentax 645D. The aperture of the 67 is automatically stopped down during the exposure, but the aperture value is not communicated to the camera.
