'How to' guide for converting a Polaroid Land Camera for modern film and batteries

[zzpza]

I recently wrote an Instructable detailing how to setup a Polaroid Land Camera that uses 100 series Polaroid film (the metal or plastic folding rangefinder cameras from the 1970's). It shows how to modify the camera to use modern AAA batteries and Fuji's FP-3000B/FP-100C instant film. It's aimed at people who don't mind getting their hands dirty (so to speak). I thought it might be of use to people here looking to get a Polaroid Land Camera into a condition that they could use with the minimum of hassle (finding obsolete batteries) and expense (finding viable Polaroid film packs). Here it is. Enjoy!

Coincidence has it I read the guide yesterday, and today I got a note in the mail telling me to pick up my 250 at the post office. Look forward to some tinkering during the weekend. Thanks.

zzpza, thank you for the link. what another coincidence, I just inherited a Polaroid Land Camera last week. Now I have a project to look forward to...

Thanks guys, seems my timing was most fortuitous!

Good and clear instructions.
Even I can follow it

Excellent contribution to the world.

Thanks for the guide. I finally broke off the springs from the back, and now I can finally feed the Fuji film through the camera without tearing the strips.

One question though - does the film pack area that the springs use to rest on need some type of support? Your posting seems to imply that it's not needed.

I glued in some foam (cut from the foam strip in the middle of the Fuji cartridge pack) in this area, just in case. It may be totally useless, but it seems to make me feel better.

I have a Polaroid Land Camera 700, which I plan to convert to 4x5. Any ideas how to recalibrate the rangefinder ?

You're welcome.

I just remove the springs, I haven't had to replace them with anything on the cameras I've done this mod on. I've since used an original Polaroid 100 (Blue Film) pack in one of the cameras without trouble also.

The Polaroid 700 was (if I remember correctly) an instant roll film camera, not a camera that uses type 100 film, which I am more familiar with. However, as long as you are not changing the lens, and you keep the lens to film distant the same, there is no need to change or adjust the rangefinder.

Wish I had seen this tip, about removing spring, before removing a Polaroid 100 back from my 150. Now I have a light leak so I have to do it again:^(

You'll no matter which conversion you plan on doing not be able to retain the same focal plane as it were. You'll need to move the lens infinity stop backwards to compensate. To attain 4x5 coverage (the existing coverage is 3.25 x 4.25, you will have to position the new film plane an inch or so backwards, or open up the film gate and make a new set of bellows to fit.

A place to start would be www.instantoptions.com

Also google (in conjunction with Polaroid conversion), Noah Shwartz, Dean Jones (Razzle, Razzledog), David Harms and Byron.

And by no means look up Littman, Litman (William, Bill or Guilermo - depending on what he decides to call himself). You are bound to come over his rants sooner or later, but try to spare yourself of them (He's evidently patented the process of converting a Pathfinder to 4x5, and defends it verociously, no matter that his idea was at the time of patenting already a 40 year old one.)
