This camera is currently modified to use 600 film. I have taken out the sensor filter and set the exposure control the darkest setting. I have not tried the ND filter option. I trim off the tabs on the 600 film pack with an X-acto knife.
Here is the text from the Polaroid site, SX-70 film will be discontiuned in early 2006
How to use my SX-70 camera with type 600 or 779 film?
Please follow these steps to adjust the film and camera:
600 / 779 Film
The 600 and 779 films have four little plastic nubs at the bottom, which prevent them from being loaded in a camera designed for SX-70 film. You have 2 options:
* You can remove the two nubs in the middle in order to load the film.
* You can use the dark slide of a previously loaded instant film to load the film without removing the nubs. Hold the dark slide (also known as black tab or cover sheet) under and slightly beyond the pack while loading it. The idea is to have something smooth that covers the nubs as the pack is inserted.
SX-70 Camera
Now that you have loaded either 600 or 779 film into your SX-70 camera, you have to overcome the fact that this film is four times faster than SX-70 / Time-Zero film.
This cannot be achieved by adjusting the exposure control settings. Even if you alter your settings to reflect the dark, your pictures will still be overexposed.
If you only plan to take photographs in broad daylight:
* Reduce the amount of incoming light by affixing a 2-stop neutral density (ND) filter in front of the lens. Please note that this will also darken the view in your finder.
* Alternatively, you can try a 1-stop ND filter and set the exposure control 1.5 stops to darken. Use a coated filter to get the best results.
If you take photographs in any light:
* Remove the filter retaining ring (the little chrome ring which surrounds the photocell) by gently pushing the tip of a small knife under the edge and popping out the ring. Remove the small round neutral density filter.
* Replace with a similarly thin piece of clear plastic (e.g. from a CD box). Re-fit the housing, insert the film and affix a 1-stop ND filter in front of the lens. The exposure-control settings should now allow you to compensate for the film speed.
Remember the exposure-control returns to zero when you fold the camera.
