UPDATED: January 20th (More photos added of compatible Polaroid backs.)
UPDATED: January 16th (Polaroid 600SE backs SHOULD work too - currently testing)
UPDATED: January 15th (Mistake corrected - Mamiya M80 backs don't work.)
The Duo kit also requires a Polaroid back (provided that you want to shoot on instant film!), NOT included in the kit.
Duo is designed to use a Mamiya Press Polaroid Back Type 1, 2, or 3 (Model No. CB100, CB101, CB103). These backs were originally used on the Mamiya Press/Universal cameras. They were also often sold for use on the Mamiya RB67 with a "P Adapter." Some useful search terms for finding these backs on the used market are:
- Mamiya Press Polaroid Back
- Mamiya Universal Polaroid Back
- RB67 Polaroid Back
Duo will also work with Polaroid backs from the Polaroid 600SE camera, which was a nearly identical clone of the Mamiya Universal. You'll want to look for a "Polaroid 600SE Back".
IMPORTANT things to be aware of:
- Third-party (e.g. Proll, NPC) Polaroid backs are unlikely to work on Duo without significant modification.
- Polaroid backs made specifically for the RB67 Pro-SD will NOT work. They have an integrated "P Adapter" that cannot be removed. See photos in "Additonal Notes, Part 4", below.
- There are some backs with wire closures (Types 1 and 2), and others with plastic closures (Type 3). Both will work.
- It was originally stated the Mamiya M80 backs would work. This was a mistake, the wrong model number was used. They rely on extinct film Type 80 film that no longer exists!
Additional notes after the break.
1. Mamiya Universal Press Polaroid Backs and "P Adapter" for RB67
|Tell-tale signs that the back has a removable "P Adapter"|
As stated earlier, the Press Polaroid Backs are often sold as Mamiya RB67 backs, with a "P Adapter." The P Adapter, which is not at all needed for Duo, simply unlatches from the back.
2. Example of a compatible Polaroid Back: Mamiya Universal Press Polaroid Back (Type 3)
3. Small variations between Type 1/2 and Type 3 backs (wire vs. plastic closures). Both work fine.
