Graflok options for 6x6 and 6x4.5?

[quixoticcassandra]

From what my research tells me, there is only the 22 Graphic and the RH-12. But I just wanted to make sure that I'm not missing anything before I go on the hunt.

Thanks in advance.

The two you named are both for 6x6.

What size camera do you want to attach your roll holder to?

If 4x5, look into Sinar Vario and Zoom. Also look closely into Horseman and Linhof Super Rollex. I may be mistaken, but I'd swear I've seen 6x6 Super Rollexes offered and modern Horseman holders are copies so ...

If 2x3, I'm not sure what's available besides Graflex' own.

So I'm asking this I guess, but would a Calumet C2 not work with a graflok? I'm looking to convert my spring back to graflok and I hadn't considered it not working...

Most insertion type roll holders will work with a Graflok. Toyo rollholders -- 48 mm thick, IIRC -- may be an exception. Of course, the roll holder has to be the right size for the camera. Ain't no C2s for 2x3 cameras such as the OPs.

FWIW, I use Adapt-A-Roll 620 roll holders, insertion type if ever there was one, with my 2x3 Graphics and 2x3 Cambo, have an AAR 620 to fit a 4x5 back for my 4x5 Cambo.

I'm still not clear on what format of camera you intend to hang these on, but it's its a 2-1/4 x 3-1/4 Graflok, then Mamiya RB67 backs are precise, cheap, and will work on a Graflok back. They're a whole lot nicer than anything anyone else ever offered to fit on the smallest Graphic cameras.

Yup, I have a 2x3.

Thanks. I'll look into those (I have the 2x3). And I agree that the mamiya stuff is more attractive than the 22 Graphic. Plus, I've heard that with thinner film in recent decades, the Graphic (tallying film distance via turns of the spool, rather than mm's of film) can have problems with exposures overlapping each other.

Do you know if the distance to the film plane would be equal with both the Graphic and the Mamiya?

[mdarnton]

They are perfectly interchangeable. The only hangup is that the darkslide on the Mamiya has little fingers that interact with the camera that prevent it from going in all the way on a Graphic, and you need to snap those off with pliers. Otherwise, it's a nice back, works fine. Of course the Mamiya is only available in 6x7 which is OK for me.

Now I'm confused. The 645 holder shown here has an opening that resembles something similar to the size of my 6x7 Horseman. http://www.ebay.com/itm/Mamiya-RB67-...item2ede43b9d2

Right box, wrong roll holder.
