Pentax 645 Digital Camera

[100] In this world of digital everything, its a sweet pleasure to take out a Rollei TLR or Pentax 645 and run a roll of Provia 100F through it. Life slows down as you compose each shot rather than do the digital spray and pray. Each shot matters and viewing the results through a good loupe is a real joy!

[Canon EF] I'm using this adapter with Pentax 645 lenses on a Blackmagic 6k camera with EF mount. Works very well. Snug fit on both lens and camera ends. This adapter allows me to use the aperture ring on the lens to change aperture.

[3] I am in a wheelchair.I just brougth a pentax 645,which is 3 lbs camera.I needed a sturdy mount to support it. I also got a manfrotto supper clamp along with the magic arm ,and atached it to a heavy duty seat borad ,which I made up. I went to local park,and me ,and the camera bounced around the whole park for three hours,and the camera survived in good order.It also made great tripod,a sort of tripod on wheels if you will

[5.2 x 4.8 x 3"] This makes it possible to use my expensive Pentax 645 lenses with my Canon 5D Mark ll.

[Front] Pretty straightforward, fits the 25mm Pentax medium format or 645 system

[0.76 lb] I use this adapter on my GFX 50S with my various Pentax 645 lenses (45mm, 75mm, 80-160mm). Love that old, inexpensive Pentax glass and the GFX makes them even better. Since there is no electronic communication between camera and lens with this adapter, it’s not an exact science to achieve a particular aperture setting. So if you need exactly repeatable results with changing apertures, you’ll find that difficult with this setup. You change the aperture of the lens on the adapter itself by turning the ring, and really you’re just guestimating the aperture if it’s anything other than wide open or closed. I still recommend it because that Pentax glass is oh so nice and worth it!

[FUJIFILM G] I purchases this to be able to use older 645 Pentax lenses on a Fujifilm GFX body. It works just fine. I like the tripod quick release mount and the aperture adjustment one the mount.

[Aluminum] Critical item for mating Pentax 645 120mm macro lens to Pentax AF-140C ring flash.� Worked great.

[1/4"-20 Female] Not sure if the other bad reviews are due to user error, but I’ve had zero issues with this adapter. I use it with a Pentax 645 75mm 2.8 lens with my GFX 50S. The images are excellent. There is no vignetting on the corners with the 75mm lens. I’ll soon be trying it with the Pentax 645 45mm 2.8 lens. It connects to the Pentax lens nice and snug. And it connects to the GFX body totally great. You have to change a setting on the GFX to shoot without a lens because there is no electronic communication between the lens and body. With this specific adapter, the f stop is changed on the adapter and not on the lens, even if your Pentax lens has the aperture ring on the lens itself. There is no clicked adjustment of the f stop on this adapter. It’s smooth as you change the f stop on the adapter. So if the lens isn’t wide open or stopped down completely, you’re pretty much guessing what your f stop is. Not too big a deal to me. The ring to change the f stop is nice and smooth. The build quality is very good. The main advantage is you can add wonderful Pentax 645 lenses to the amazing GFX cameras. Pentax 645 lenses are pretty darn cheap on eBay.

[5 x 4 x 3"] Arrived early - Works perfectly with all three Pentax 645 manual lens I have on Sony A6000
