Large format cameras
Using roll film backs on 4x5 view cameras:
If you already own a 4x5 view camera, a cheap way to get into 6x12
is with a roll-film back. You're saved the hassle of loading film holders
but the other operational annoyances of the view camera will still slow you
down. On the plus side, even with the very cheapest view camera and 6x12
back you get perspective control.
Roll film backs are available for all roll-film sizes to
6x12 the most common being 6x7 and 6x9. There are two types of roll-film
- Graflock-type holders:
- Some 4x5 cameras have a back (Graflock, this
standard was introduced on the Graflex cameras) where you remove the
ground-glass assembly and replace it with a roll-film back.
- There are
plenty of brands to chose from: Graflex, Singer, Linhof (super-rollex),
Mamiya RB, Horseman, some of which can be found for quite cheap.
- cheaper Chinese-made Shen Hao backs:
- Art Panorama 6x17 back: see review
- SH612 multi-format - has masks for 6x12, 6x9, 6x6 and 6x4.5 -
- Slide-in type holders:
- These holders are flat because the film spools
are at one end. They can be inserted under the ground glass like a sheet
- faster to use and it is said that the film
flatness is better
- Almost all the cameras accept them, but be sure to check
- The Calumet holders are quite cheap and are produced in 6x7, 6x9, 6x12 (the latter is quite expensive actually).
Sinar has a vario holder which allow you to switch format (from 6x4.5 to
6x12) at any time, for $US2500 new.
