When I ordered the 4x5, I added in the upgrades for the broken 6x9 I got off ebay. Contrary to the instruction, these things aren't super trivial to install. It all works, but I think I'm about 0.5mm on a couple of holes away from it not working too well at all!
Also think I'm going to need a step up right to actualy use my filters. Atleast the 100mm filter holder wont go on as the screw at the top of the cable release stick out too much.
