en fait, le SX 70 Blend, semble être un 600 avec un filtre de densité sur le pack...
on peut aussi modifié le SX 70 pour utiliser du 600 (voir plus bas)
je pense que le Blend est uniquement vendu online

Question
How can I use my SX-70 camera with 600 or 779 film?
Answer
Modifications must be made to both the film pack and the camera in order to use 600 / 779 film with an SX-70 camera:
Film Pack Modifications
600 and 779 film cartridges have four little plastic nubs at the bottom front of the pack that prevent them from being loaded in a camera designed for SX-70 film. To compensate for this, there are two options:
Using a knife, carefully remove the two middle nubs, so that the film loads smoothly; or
Use the dark slide of a previously-loaded instant film pack to load the film without removing the nubs. To do this, 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 covering the nubs as the pack is inserted.
SX-70 Camera Modifications
600 and 779 film are four times faster than SX-70 / Time-Zero film, and this must be accounted for when using them in an SX-70 camera. This cannot be achieved by adjusting the exposure control settings alone. Even if the camera settings are adjusted to reflect the required dark compensation, the pictures will still be overexposed. Use the following guidelines:
When taking photographs in broad daylight:
Reduce the amount of incoming light by gluing or taping 2-stop neutral density (ND) filter material (.6 – #98 or #3403, available at most camera stores) in front of the lens. Please note that this will also darken the view in the viewfinder. Use a coated filter to get the best results.
Alternatively, try 1-stop ND filter material (.3) and set the exposure control 1.5 stops to darken. Again, use a coated filter to get the best results.
Taking photographs in diminished 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 the filter with a similarly thin piece of clear plastic (e.g., cut from a CD case). Re-fit the housing, insert the film, and affix 1-stop ND filter material (.3) in front of the lens. The exposure-control settings should now compensate for the film speed.
Remember that the exposure-control (lighten/darken) wheel returns to zero when the camera is folded up.
