Pentax's compact enthusiast DSLR — the *ist DS, APS-C CCD, K mount, pentaprism, AA power, 2004.
The Pentax *ist DS was released in 2004 as a smaller, more affordable digital SLR below the *ist D in Pentax's *ist line of APS-C bodies. It was aimed at enthusiasts and newcomers to digital SLRs and kept the Pentax K bayonet, so existing K-mount lenses could be used on it.
This is an APS-C digital SLR on the Pentax K mount. It uses a CCD sensor and, unlike some rivals in its class, retained an optical pentaprism viewfinder for a bright eye-level view. It is a stills-only body with no video, and it runs on AA-type batteries, which was a practical feature for travel. Composition is through the optical finder without live view.
The pentaprism finder and AA power make it a straightforward choice for beginners and travellers who want an optical viewfinder and easily sourced batteries. Its resolution and screen are modest by current standards, so it is best seen as a low-cost entry into Pentax digital that pairs well with older K-mount lenses.
On the used market, check the shutter for clean operation and any actuation count against its rated life, and inspect the CCD sensor for dust and marks; early CCD bodies may show colour shifts and service parts are limited. Test the rear LCD for dead or stuck pixels, check the card and battery door latches, and confirm the AA battery compartment contacts are clean. Check the grip rubber and note the K mount's compatibility with a long line of Pentax lenses.
