thanks Jeremy, it must have one of Dave G"s posts..I'll check

btw is the One O clock Band still in existence at NTSU?

Well, it's UNT (University of North Texas) now and no longer North Texas State University--though as a interesting footnote in the history of the school, they did leave the radio station KNTU instead of changing the call sign :D

Yes, the 1 O'Clock is still going strong--I catch every concert I can of the 1-3 O'Clock lab bands since I've got friends in the 2 and 3 (though this year they may be in the 1).

Apparantly DaYi has come out with a newer version of their 6x17 back, more can be read about it here: www.focus-dayi.com

Dave--I don't see why it wouldn't work with your Crown, as long as it has a Graflok back.

Just got the back - paid $ 519 ship'd....from the day I bought it off ebay to today when it was delivered - it took 11 days....Packing was great - completely encased in styrofoam....First impression: this thing is very low tech and almost crude in its build/finish... there are still some metal shavings inside the thing ! BUT - it looks like it will work !

The cheap black yarn used as a light seal was not in the best shape in one area - so I patched with my own light seal kit...the focusing unit - again crude, looks like it will work well in the field with its a long bellows for viewing the ground glass.... I will shoot this beast in the next few days and let you all know how it goes..

Are these things any good? I like the idea of having the opportunity to shoot different aspect ratios of rollfilm with a technika I'm going to buy. This apparently covers a few all in one back. I want to be able to shoot 6x6 and was thinking of cropping back from the 6x7 rollex back the guy is including with the camera. Any info would be nice. Whether anybody has used one. I like the idea of being able to shoot 6x17 panoramics too as cameras specifically designed for shooting that ratio are rediculous expensive.

I've made several posts on it. Do a search on "DaYi" and you should turn up a few threads.

The Caoersi 6x17 cameras are very reasonable prices, lower than Fotoman because you buy direct from the manufacturers. I looked at the options including the backs you link to before buying a Gaoersi.

The 6x12 back looks a good option and is a reasonable price.

I've only noticed the numbers on the backing paper now after fishing it out of the waste paper bin. They seems to be for 6x45, 6x6 and 6x9 right. What about 6x12 and 6x17? I guess you just count up every so many numbers right? Coming across these backs has made me even more interested in the tech v now. I never knew I'd be able to experiment so much with it. :)

For 6x17 it's 2, 5, 8, 11. I never use my Gaoersi for 6x15 or 6x12 although it's easy to switch mid roll.

How does a 6x17 back fit on a 4x5 technika when 17cm is longer than 5 inches?

01-12-2008, 11:04 AM
The 6x17 back sticks out further i think by a couple of inches and it has a build in ground glass since focusing will be further away from the lens than with the 6x12 back.

The groundglass isn't built into the back. There is a separate groundglass viewer used for focusing, and then it is replaced with the back for making the photograph.

The 6x17 backs for 4x5" cameras are all essentially expansion backs, like a 5x7" back for a 4x5" camera (Wista makes one of these).

Found this link recently:

and was pretty fascinated. I have a Shen Hao 4x5, and already use and like my 6x12 Horseman back.

Has anyone used this back? Or have any information about whether it's worth the purchase? If it's wonky, then I may save my shekels for the 6x17 or 7x17 Shen Hao offers. (although if I spend any more on cameras, I may just find myself fighting the cats for food)

many thanks for wisdom imparted....

Colin, you might consider that for a fairly similar price you can get a gaoersi or fotoman 6x17...

I am currently debating between that option and a 6x17 rollfilm back for a 5x7 or 4x5 and thinking that a standalone camera will be used much more. Haven't yet heard/read anything negative about the gaoersis or fotomans... apparently their mechanisms are simple and robust.

Try a search on "DaYi" and you should turn up one or two threads on the DaYi 6x17 back, which is similar to the ShenHao, and a few others. I have the DaYi 6x17 back, and I find it useful.

I'd get a true 6x17 camera instead of the back. If you're going out specifically for panoramas, less to carry and roll film is VERY convenient for travel. I'd been toying with getting a DaYi as they come with a ground glass attachment which I would find extremely useful for critical framing.

Downside to these cameras is you may need to get new lenses or get used to swapping them out with your Shen.

I use the Shen 617 back on an Ebony 45s which allows me to do vertical as well as landscape aspect. It works very well and I can have a few sheets of 4x5 with me too...Evan Clarke

I have a Da Yi that I picked up for about $400 (new) on Fleabay.

Very basic, robust, but a bit awkward to use.

What I do like is the fact that I retain all the movements of the view camera. I would not consider a panoramic camera with at least some rise/fall capability - unless you are happy with the horizons being smack in the middle, or curved.

I also upgraded a couple of lenses - I noticed that sharpness fell off at the ends of the image even stopped down.

There is an article (http://www.largeformatphotography.info/shen-hao-6x17.html) on the LF Forum on the Art Panorama 6x17 roll film back made by Shen Hao.

BTW, in the Robert White link, the image shows a "SH617 Panorama" while the one on Badger Graphic's website (http://www.badgergraphic.com/store/cart.php?m=product_detail&p=123) shows a "SH617 Art Panorama" - anyone know if they are the same thing? Wondering why the labels are different....

A couple of years ago I was in a similar position, I decided to buy a Gaoersi 6x17 and haven't regretted the decision, they are well made robust cameras and significantly cheaper than the Fotoman as you buy direct from the manufacturer.

It's very much easier to use a dedicated 6x17 camera, I use mine hand-held 90% of the time and so far it has been to 3 continents in the time I've owned it.
