Hello,

It is my intention to try a 617 roll film back on my ShenHao HZX57-IIA with a graflok back.

Can I have some advices from members who uses thoses backs:
-ShenHao SPC617 Roll Film Back https://www.badgergraphic.com/store/..._detail&p=3711 (6x17 only)
-Dayi 617 Film Holder for 5X7 camera http://www.bhcamera.us/dayi617back-57camera.php or on ebay http://www.ebay.com/itm/270862787997 (with 6x14 and 6x12 masks)
Both are 600$, are they worth this price?
-I know about the Canham 6x17 Motorised Roll Film Back but it price is 2x the cheapest ones.
I suppose that thoses 3 backs will fit on the ShenHao. Feedbacks will be appreciated.

I know also that the cheapest way is to make an half-slide! How do you do a clean cut, on the router?

Thanks for the info.
