Hello Madmodder,
I have been a member here for years, but with periods of inactivity as I tend to cycle through my hobbies (photography, guitar, machining).
My daughter bought an Fujifilm Instax 210 camera while traveling, and has been using it a lot. This bumped my enthusiasm for a project which has been on the back burner for a while. I hacked a 100 Automatic Land camera with a Mamiya 105 f3.5 from a TLR a few years ago, and then the last call for pack film followed shortly after. Having consumed all but one remaining box of FP-3000B, that camera has lurked in the deepest recess of the closet, till now.
There are plenty of bodged up Instax wides gaffer taped to Polaroid Land cameras and Pathfinders, but I hadn't seen much information on the net on optimising such modifications. The aim being to couple the excellent Zeiss combined range/viewfinder accurately to a fast and sharp lens with manual aperture and shutter control and a flash shoe.
Here is the first episode of my attempt to document such an Instafrankenroid.
In an idea world, hacking Instax wide to the original film gate of a Polaroid 180/190, while keeping the rangefinder system would be the holy grail. As you can see, the design features central to both Instax and Polaroid designs are unfortunately in direct conflict in the upper focus arm/development roller area.
