It was a fine, highly regarded camera in its day. It had most everything you wanted but the Nikon F had more. The Pentax had a screw-mount lens system and they had to and did change it. It's difficult to connect electronic gizmos to the body and camera with a screw lens mount. But it is s small, fairly light weight camera. I have a beat-up one and I wish I had a good one. Have fun.
I had a Heiland H2, but something put me off of it. Just the way it handled seemed "off" to me and I sold it. It was however undeniably well made and pretty so far as cameras go. I may give one another chance some time.
