6x12 612 Roll Film Back Holder for Linhof Wista 4x5

Brand new DA YI 6x12 roll film back for 4x5

a story about this device

A group of large format amateurs fancied about building their own 4x5 / 6x12 / 6x17. 15 months later, they did it.. and this item is a by-product along the road

They co-operated with DA YI when it first rolled out the 6x12 film back for 4x5, and they have worked together to improve the whole design and small details.

This is a better and improved DA YI 6x12 roll film back than the 1st cut, which came out 2 years ago.

This is probably the best one in the market. OK, as far as I know, another manufacturer Shenhao (in Shanghai China) has copied the design from DA YI, but remember that DA YI is the original maker of this universal film back

Actually, they have made 6x17 roll film back as well, I have it listed on ebay. Let me know if you're interested.

a short review

This clever two part 6x12 format International fit attaches via a Graflok 4x5 back. So it's suitable for Sinar, Linhof, Horseman, Toyo, Wista, and other 4x5 view or field cameras with an international back

The roll film holder is held in place by two spring steel bands which compress onto two protruding lugs on the roll film part of the holder. The film is loaded into the holder with the help of a spring loaded retractable bottom bracket. The film is advanced by a knob rather than by a lever. There is a large spring loaded pressure plate (75x120mm) to keep the film flat and rollers at each end at the bend near the film spools. On the half of the holder, immediately next to the dark slide, there are two pin rollers like the kind on later Graflex RH-8 holders to facilitate the film transport.

The Dark slide moves in a recessed track and pulls in and out smoothly.

The film advance is manual and the frame number is indicated in the window in the back of the holder. One can observe the frame numbers as printed on the back of 120 film (precluding 220 film). By advancing the film on alternating frames, i.e., 1,3,5,7, etc., on either the 6x12 or the 6x9 windows proper frame spacing can be maintained quite easily.

(some of the wording are from ebay user "sky_and_earth", thanks)

it has a default opening of 6x12 (56x114 mm); it also comes with masks for 6x9(56X86mm), 6x6(56x60mm) and 645 (6x45mm)

it shows how the 6x9 mask is attached, very convenient
