Q: What's the difference between a 600 and an SX-70?
A: The 600 was Polaroid's entry level camera. They are easily identifiable by their boxier shape, hence their nickname of "Box Polaroids". The SX-70, however, was the brand's flagship
model of instant camera. SX-70s have sharper, variable focus glass lenses, as apposed to sometimes fixed focus lenses on the 600.
Q: Where do I get film?
A: Film is readily available online on Amazon and from Polaroid Originals' website. You can also get it locally at Target, Best Buy, Walmart, Microcenter, Meijer, and at some photography stores. Search for either 600 or SX-70 Polaroid Originals film online.
Q: Is there a difference between 600 and SX-70 films?
A: Yes, 600 film is a "faster" film meaning it needs less light than SX-70 film in the same setting to get the same exposure. This leads to faster shutter speeds on a 600 camera. 600 film is also easier to get locally. This is a major advantage of having your SX-70 converted to use 600 film.
