Example gear: Bronica SQ-A + PS 80/2.8, Hasselblad Waist Level Finder with adapter, Reflx Lab Lightmeter, works well with all part without any additional sanding. (Also works with original AE-I finder, so the original waist level finder should be fine Compatible Cameras/Lenses: All Bronica SQ cameras and S/PS lenses, techinically ETR series but I don't have one of them. The rear of the lens should be 82mm to fit best, which is a standard for the SQ series at least. Addtional Tools Needed: one M3 12 bolt, one M3 4 * 5 Heat Insert Nut
