Ricoh KR-10

The Ricoh KR-10 is an electronic 35mm SLR that introduced aperture-priority auto-exposure alongside full manual control. It uses the versatile Pentax K-mount and features an electronically controlled shutter reaching 1/1000 second. The viewfinder includes an LED display for exposure information, providing a more modern user experience than the earlier needle-based models while maintaining a compact, lightweight chassis. On used examples, the electronic shutter relies heavily on battery power, so clean contacts are essential. The foam light seals and mirror dampers are standard wear points that typically require attention. SDS technicians check the accuracy of the auto-exposure system and ensure the film transport mechanism operates smoothly without slipping. The plastic exterior components should be inspected for cracks, particularly around the battery door.
