Up for sale is a Da Yi 6x17cm (3:1) panoramic 120 rollfilm back to fit most 4x5 cameras. In fact, I loved using this back so much that I recently upgraded to the ultimate 617 camera (Shen-Hao TFC617) and now I really can't justify keeping this around unused. I've shot many, many rolls of Velvia and Ektar through this and even entered a few competitions with photos I took with this back. It fits on a regular 4x5 back, on most cameras where you can take the back off (I can never remember if the specific mount is called'graflok' or'international' or what, but it certainly fits the Toyo 45G I've used it on for years, as well as a Technika III I had lying around and just tested).

I just can't guarantee it will fit your camera, so please do your own research. Because the 617 format is wider than 5", the back has to be offset behind the usual film plane, which means that a you can't use the usual filmplane glass so it comes with its own separate viewfinder, and b because the light rays have to still make it through the 5" opening there are only limited focal length lenses that can be used. For 90% of the photos I've taken with this, I've used a Fujinon SWD 90mm lens, but I've also used 135/150/180mm with no problems. I can't remember the shortest length possible maybe 72 or 80mm? Because I don't have any of those uber-expensive XL lenses anyway.

I do recall reading somewhere that 180mm is the max length possible, but I have also successfully used a 270mm Tele-Arton (because it's a Tele it behaves mechanically as if it's a 180mm, even if it barely covers the 617 film area). But really, for me, 90mm is all I need on 617. Despite the limited usable focal lengths, this is a lot more versatile than a fixed'point-and-shoot' style like the Technorama or GX617, because you get to use all the shifts, tilts, swings, and whatever else of the camera that you attach it to. You also get proper full-sized ground-glass focussing instead of a dinky little viewfinder. Condition-wise, it looks extremely good (I could almost say that it looks barely-used, except that I know how much I've used it).

The glass in the viewfinder is clean and clear, the film-transport and darkslide glide smoothly, the pull-out bellows-shade on the viewfinder are clean and supple. The only thing that is different to when I got it is that I've'upgraded' the film-number-viewing holes with a few slices of blank Ektar ends so that light doesn't bleed into the back of the film. The reason I did that says more about the quality of Efke backing paper than anything about this back, and I haven't had a problem since (if it's too dark for you to read the numbers with it in, it's only 1 screw to undo to take them back out again). Also, technically it should come with some little black-out bits to screw in on the sides so that you can take 614s or 612s with it. I was going to at one point and never did, and never missed it.

This is a second-hand item, it is old and as well described as I can. I'm still willing to post it internationally, but if Australia Post won't take it then it will have to go via courier and they can get expensive. If one of my listings has a'best offer' button, please feel free to use it.

If it doesn't, please don't make offers. If you're from elsewhere please message me and I'll entertain the thought, but only fully insured/tracked/signed so it might get expensive.
