Pentax's entry K-series DSLR — the K100D, APS-C CCD, K mount, in-body SR, AA power, 2006.
The Pentax K100D was launched in 2006 as one of the first bodies in Pentax's K-series digital SLRs, replacing the *ist naming. It was an entry-level APS-C DSLR aimed at newcomers and enthusiasts, and it introduced Pentax's in-body Shake Reduction to the affordable end of the range while keeping the Pentax K bayonet.
This is an APS-C digital SLR on the Pentax K mount. It uses a CCD sensor and an optical pentamirror viewfinder, and it includes sensor-shift in-body Shake Reduction, so stabilisation works with any mounted lens including older manual ones. It runs on AA-type batteries and is a stills-only body with no video or live view; composition is through the optical finder.
In-body stabilisation on any lens, AA power and a simple layout make it a practical beginner and travel camera, particularly for owners of older Pentax glass who benefit from the shake correction. Its resolution and screen are modest by current standards, but the stabilisation and mount compatibility give it lasting appeal as a budget body.
On the used market, check the shutter operation and any actuation count against its rated life, listen for the Shake Reduction unit rattling normally versus a faulty rattle, and inspect the CCD sensor for dust and marks. Test the rear LCD for dead or stuck pixels, check the card and battery door latches, and confirm the AA compartment contacts are clean. Check the grip rubber and note the K mount's broad compatibility with older Pentax lenses.
