The Bronica ETR-Si is a modular SLR. With interchangeable backs, lenses and viewers, the ETR system is versatile. It is a fully manual camera that shoots medium format (120) film. The camera can be found at considerably lower prices than many comparable cameras. While it does not match the quality or style of the high end medium format cameras, the ETR-Si makes an excellent budget conscious choice that can produce professional quality images.
It requires a battery to fire the shutter at any speed other than 1/60 frame per second, and there is no built-in exposure meter. However, the batteries are inexpensive, and metering can be done easily with a handheld meter. The AE viewfinder could also be used. What the camera does do, it does consistently well.
