Polaroid SX-70 lot of the technology used in the folding SX-70 cameras was later used in the production of rigid "box" type SX-70 cameras, such as the Model 1000 OneStep, Pronto, Presto and The Button. These models, although also utilizing SX-70 film, are very different from the folding SLR SX-70s. MiNT Camera modified SX-70 into SLR670a (it uses 600 film directly without adding a neutral-density filter) and SLR670m (the only SX-70 with shutter priority mode). Built using vintage Polaroid SX-70 cameras. The SLR670-S has the ability to set manual shutter speed. This is the only Polaroid that can set manual shutter speed
