Tewe Variable Viewfinder drop down Shutter speeds and metering areThis Tewe viewfinder features a variable framing system that allows it to be used with lenses from 35mm to 200mm. This isn't just a "cropping" adjustment: there's some optical zoom action happening here, too. Light internal dust, minor cosmetic wear, good working order. A neat little viewfinder, with original case.
