I did have one issue with the Canham 617 back, that being the fourth and final shot on the roll being cut off at the end of the roll of film. So I went to the maker, Keith Canham to ask him about that problem (how many times can you do that?). He said this problem was caused by winding too much paper leader on the takeup spool during the loading step. It has to be the bare minimum amount of leader on the takeup spool before engaging the autowind step. So the trick is to ace the process of getting the paper leader just catching and then starting the autowind. If, when you hit the autowind, the paper leader doesn't engage properly, you just turn it off and try again. With this guidance in mind and some more practice, I shot 21 rolls of 120 film on a recent trip with not one single frame cutoff problem. It does require a bit more attention than a manual roll film back, but I think it yields a very flat film plane and is worth it in the long run. Keith said he should probably modify his roll film back instructions with this extra guidance, but I don't know if he did that yet.
Here's a link to my video portfolio of 35 panoramic (6x17cm) images.

Pretty slick stuff. Tony your videos are great and I think I wasn't aware of the 6x17 back before now. I think I could make this work on my 5x7 as well (with a little woodworking etc.) Thanks

Steve,
Thanks for the kind words! I definitely think you could adapt the 6x17 to the 5x7. Please let me know if you build an adapter. I'd love to see some photos and results.
Take care,
Tony
Thank You for sharing! Some beautifull pictures. Also your other video's are very instructing: no internet knowledge but pure your own experience. This helps a lot and is so much time saving: e.g. using the 210mm for panoramic: I couldn't find users experience on the cropping, now I know it's not me causing it ;-)
Thanks Charles! I'm glad to hear the video was helpful!
Sincerely,
Tony
