How to downgrade 3000 6.20 to 5.03?

Questions about vintage camera film (mainly polaroids and 620)?

• I am looking into buying either : A Polaroid SX-70 Alpha 1 Model 2 Land Camera from the late 70s A Nomad 620 A 1950s Savoy 620 OR a Big Swinger 3000 Some need 620 film which is my first question: online is mainly either extremely expensive or expired. Where can I get cheaper film for these cameras (preferrably in packs) and for the polaroid cameras, those are old and I am looking online for older polaroid films. Mainly they are either expired or used for other models other than the ones I want to buy What film do I buy and where can I get it?

• Answer:

  Let's see... The sx-70 http://shop.the-impossible-project.com/shop/film/sx70 run on that. The Big Swinger runs on http://shop.the-impossible-project.com/shop/film/type100 The two 620 camers run on 620 film. Cheapest way to run this would be to respool film http://www.brownie-camera.com/respool/respool.shtml Personally I wouldn't bother with any of these. Polaroids are, well, polaroid. The 620 cameras were cheap point and shoot cameras from their day. But, then again, I don't care that much how cool my camera looks. If you want to experiment with something different than 35mm film look for something that runs on 120 film. Easier to get and relatively easy to process thanks to the lomography movement.
