The KR-5 Super is one of a series of SLRs for 35mm film by Ricoh, all accepting K-mount lenses. Others include the Ricoh KR-5. While essentially similar to the original KR-5, the "Super" offers a few improvements, including faster f/1.7 and f/2.0 standard lens options. While still limited to 1/8 second as the slowest shutter speed (besides B), the top speed increases to 1/1000 of a second, and the maximum flash sync speed is now 1/125 of a second. While there is still no PC terminal for attaching an external flash, the hot shoe has an additional contact which permits dedicated Ricoh flash units to illuminate a flash-ready LED beneath the viewfinder eyepiece. Another LED faces forward to indicate when the self-timer is counting down before exposure. The camera was introduced in 1978 and was the successor to the original KR. The KR series was one of the lowest priced SLR’s on the market. The camera came with Ricoh Rikenon 1:2 50mm lens and some consider it one of the sharpest 50mm f/2 ever produced. One thing worth mentioning is while basically all K mount lenses (with the exception of those without an aperture ring and the DA digital only lenses) will fit and function on the KR-5 Super, not all Ricoh K mount lenses are compatible with a Pentax body.
