The Zenza Bronica ETR is a series of 4.5×6 SLRs manufactured by The Zenza Bronica Industries Inc., Tokyo, Japan.
The ETRS is an improved version of the ETR. The main improvement is the interchangeable viewfinder system. The newer AE II and III finders are not fully compatible with the older ETR cameras, because there is a new electronic connector pin. The shutter button lock has been redesigned. It has three settings, unlocked, shutter release button lock but drive and cable release unlocked, and all locked. The neck strap mount has been changed to a design with an eyelet while the previous one was a spring catch style mount used on the Bronica 6x6's, along with many Hasselblads and Kievs.
The camera, 75mm f/2.8 lens, hand grip, waist level finder, prism finder, 120 back, lens cap, and a -3.5 diopter.
Cosmetic: Has little signs of use all over.
Optical: Viewfinder is clean, but the matte has a bunch of scratches on it. Lens clean with a small amount of dust and it has no haze/fungus/scratches.
Mechanical: All shutter speeds are accurate and all mechanical functions are working perfectly.
