Arca Swiss 6x9 rollfilm back for Arca Swiss Field Camera

[Oren Grad]

You now have me wondering if I should purchase a few dedicated digital lenses for the 6x9 back.

Many of the "digital" lenses won't cover 6x9.

I have the 90mm Apo-Sironar-Digital, which I think was the first view camera lens labeled as a "digital" lens. It covers 6x9 with room for movement, and is absolutely stellar in every way. Then again, my ordinary 75/6.8 Grandagon-N and 100 Apo-Sironar-N, when stopped down, are excellent too. If you're working at f/22 - f/45, you're not necessarily going to see much advantage from a "digital" lens.

This question of scanning medium format images can be considered as a major drawback of using 6x9 instead of 4x5".

Depends what scanner we are talking about. For an Imacon scanner, maximum resolution is 2,040 ppi for 4x5. For for 6x7/6x9 it is 3200 ppi. So quite comparable file sizes.

It makes sense to use digital lenses with film if you are doing double duty with a digital back. The 90mm APO Sironar Digital covers 4x5 with room for movements. I've gotten great results this past weekend. The 55mm APO Sironar Digital covers 6x12 with room for at least 10mm rise. The 55mm requires the strong (5x) center filter when used with film to get even corner illumination with Velvia 50.

I use the Calumet C2N and have no problems with film flatness.

I don't know if A-S makes any modifications to the Horseman holder, but I do know that my Horseman 6x7 holder works just fine on my A-S Discovery.

Grab the Horseman, forget the AS specimen. A wise decision. You have nothing to loose.
