Just got a SX70 (first model, chrome/tan) off ebay and loaded it up with SX70 film, but all the shots seem grossly overexposed. I have even tried putting the adjustment all the way to darken but it still overexposes. Did I buy a dud?

Make sure you're using the right film. The one to use (if it's still available) is "Time Zero Supercolor". The 600 type film is 4 times faster in speed than what the SX-70 was designed for--and the camera can only be adjusted by +- 1.5 stops. Or you could try using the 600 film with a neutral density filter.

The film I am using is branded 'SX-70 film'. Is this the same ASA as the Time Zero film? This was the only SX70 film I could get in Australia.

Here, by the way, is a neat little site with information on the SX-70, including tricks to use it with faster film:

According to the Polaroid web site, the type 600 film is rated at ISO 640 while the Time Zero film is 150. Sounds like you are using the higher speed film which is why it's overexposing. Here's the site to order the film online:

The film I am using is SX70 film. The problem is definately with the camera... I ended up finding another SX70 really cheap and put the film from the bad SX70 in the new one and it exposes perfectly. Oh well, at least I have a funky chrome & tan paperweight!
