Camera Compatibility
Pentax claims that all their auto-focus cameras are backward compatible with K-mount lenses dating back as far as 1975 without need for an adapter. However, the camera cannot read the set f-stop of K and M series lenses and must stop-down momentarily to meter. All Pentax and Samsung D-Xenogon lenses are interchangeable since Samsung adopted K-mount on their camera bodies. The Samsung GX-10 and GX-20 are the only two models compatible with SDM lenses. Some Pentax SDM lenses are also not compatible with some early production digital SLR's.

Famous quotes containing the word camera:
“The camera has an interest in turning history into spectacle, but none in reversing the process. At best, the picture leaves a vague blur in the observer’s mind; strong enough to send him into battle perhaps, but not to have him understand why he is going.”
—Denis Donoghue (b. 1928)
