This is the Mamiya/Sekor 528TL. Known in the US as a Sears Auto 35TL, it’s a 35mm SLR, but an unusual one. The lens, a 48mm f2.8, is fixed and cannot be changed. But it does have a light meter, an automatic aperture setting and lovely shutter sound. Unfortunately, mine is not working, but I hope you enjoy the video anyway.
