Arca-Swiss rollfilm backs

[Ron Spencer]

Does anyone have any experience using the Arca-Swiss 6x9 and 6x12 rollfilm backs?

How good are they as far as flatness and functionality?

How do they compare with Horseman's film backs?

Thanks for you help.

I think they are Horseman backs, just repackaged by Arca Swiss.

Ron: It's my understanding that Horseman actually makes the Arca-Swiss backs. Whether or not Arca "selects" or tests or tweaks chosen backs, then puts their name on them, I don't know, maybe someone else here does. I use 220 Horseman backs in the 2x3 size on my Arca 6x9, and they work fine; I didn't have the option of the Arca backs, as they're only available in 120 versions. Some grouse about the lack of critical sharpness or flatness on rollfilm backs, and I haven't made large prints or done any serious testing in this format--has anyone else?

[J.T.]

They are Horseman backs with the Arca name plate. No other changes from what I understand.
