The camera uses M42 mount lenses and was available in black or chrome.
With the standard lens, the camera weighs just under 2.5 pounds (1+kg.) This particular camera was a later model since it has the atom symbol on the prism front. Earlier ones had a “Sears” nameplate on the prism front. The TLS had TTL metering. Top shutter speed is 1/1000. The 1.4 50mm was likely a premium lens.
