I just modified a friend’s Polaroid Automatic 100 Land camera to take normal AAA batteries. I followed the battery conversion instructions from option-8’s excellent Converting Vintage Polaroids, and it went really smoothly.
I did end up having to shave a few mm off of the two plastic supports that held up the original battery holder to get the battery compartment door to close, but a Dremel made quick work of that.
It’s shooting dark, but apparently that’s pretty common with these.
Normal (exposure dial set to middle)
+1 stop (exposure dial at plus 1 full notch toward Lighter)
+2 stops (exposure dial all the way toward Lighter)
It’s still a bit dark at maximum brightness, but that’s kind of where I like it.
Note: despite the mind-bendingly tragic demise of Polaroid, Fuji makes a nice pack film. I like the FP-100C better than Polaroid’s 690 (yuck) and 669, anyway.
I didn’t know the 100 took those films. I have a 100 that I thought was reduced to decoration, like the J-66 on the same shelf.
