Pentax's updated DS — the *ist DS2, APS-C CCD, K mount, pentaprism, larger LCD, 2005.
The Pentax *ist DS2 was a 2005 revision of the *ist DS within Pentax's *ist line of APS-C digital SLRs. It carried forward the DS formula with a larger rear screen and minor updates, sitting as an enthusiast-oriented body that kept the Pentax K bayonet for use with existing K-mount lenses.
This is an APS-C digital SLR on the Pentax K mount. It uses a CCD sensor and retains an optical pentaprism viewfinder for a bright eye-level view, and it runs on AA-type batteries. It is a stills-only body with no video and no live view, and the main change from the DS was a larger rear LCD for reviewing images.
The pentaprism finder, AA power and larger screen make it a practical choice for beginners and travellers who prefer an optical viewfinder and easily sourced batteries. Its resolution is modest by current standards, so it is best viewed as an affordable route into Pentax digital that works 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 colour shifts and limited service parts apply. 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 long backward compatibility with Pentax lenses.
