What to Look for in a Used Mint SLR670-S
The Mint SLR670-S is a converted Polaroid SLR680 that adds manual shutter override and 600 film compatibility. When buying one used, the condition of the exterior, film compartment, and conversion work matter as much as the camera's basic functions. Here's what to check before you buy.
Exterior Condition
Used instant cameras often show wear. The example listing describes a unit in Very Good Condition with minor marks and scratches on the exterior. That's typical for a used camera, but check for anything deeper like cracks or missing parts that could affect sealing or handling.
- Scratches and marks: Surface wear is normal and usually cosmetic. Deep scratches near the lens or viewfinder might affect image quality or light sealing.
- Tripod mount: This converted SLR670-S includes a tripod mounting hole on the bottom. Verify it's present and functional if you plan to use a tripod.
What the Listing Confirms About This Example

Mint SLR670-S Instant Polaroid Film Camera - Black - USED - Mint SLR670-S Instant Polaroid Film Camera - Black - USED: All functions including exposure, flash and film transport have been film tested and are in proper working condition. Full functional testing is the most reliable sign that the camera works, especially for a converted model.
- Mint SLR670-S Instant Polaroid Film Camera - Black - USED: Comes with 90 day warranty. A warranty provides recourse if issues appear shortly after purchase. Not all used cameras include one.
Film Compartment and Rollers
The film compartment is a critical area because dirt or corrosion there can scratch film or cause jams. The example listing notes a clean compartment with light, typical signs of use on the metal rollers.
- Check for cleanliness: Look for dust, residue, or corrosion. A clean compartment suggests the previous owner maintained the camera.
- Inspect the rollers: Light wear on metal rollers is normal after use. Heavy pitting or rust could affect film ejection. Ask the seller for a photo if the listing doesn't show one.
The Conversion: What It Means
This SLR670-S has been converted to use Mint's manual override shutter speed adapter and can now use 600 Polaroid film with auto modes. That's a key upgrade: original SLR680 cameras only work with 600 film natively, but the Mint conversion adds flexibility. Verify that the manual override works smoothly and that the auto modes function as expected. The listing confirms film-tested operation, which is the best assurance you can get without handling the camera yourself.
What the Listing Doesn't Tell You
The listing doesn't specify battery condition or expected battery life. Instant cameras rely on the battery in each film pack, so the camera itself has no internal rechargeable battery. That's one less thing to worry about. It also doesn't mention the condition of the bellows or light seals beyond the general "very good" rating. If possible, ask the seller about bellows light leaks or test with a fresh pack after purchase.
