Pentax K100D Super review

Carrying a 6-megapixel CCD, the K100D Super is the successor to K100D, an entry-level model adding anti-dust features to an already ambitious spec including a body integral anti-shake system, large 2.5in LCD, continuous shooting at just over 2.5fps and sensor sensitivity running up to an impressive ISO3200.

With the limited choice in resolution of APS-C size CCDs available, it's a pity, but perhaps unsurprising, to see the K100D Super carrying the same 6-megapixel resolution sensor as its predecessor. Nevertheless, the maker has upgraded the moving CCD platform to include the anti-dust features of the pricier K10D.

This includes a special anti-static coating on the low-pass filter, as well as the ability to vibrate the sensor thereby literally shaking dust specks from the surface of the filter pack. Although sensor vibration is fairly low frequency and not as effective as the system found on the Olympus models it's a handy feature all the same.

Other improvements are firmware based and available for the K100D, but include official support for the larger capacity SDHC format memory cards, taking capacity over 2GB and compatibility with Pentax's expanding range of pro-grade SDM lenses with built-in focus motors.

Like the previous model, the diminutive K100D Super sits sweetly in the hands, but the combination of stainless steel chassis and 4 x AA batteries make it feel a good deal heavier than its rivals. Two lithium CRV3 disposable cells help lessen the load and provide several hundred snaps, but they're pricey.

Up to the eye, the Pentax doesn't disappoint, with a 0.85x magnification the viewfinder is clear and contrasty though not quite as bright as the Nikon D40. The bundled 18-55mm kit lens is every bit as good as rival offerings, better in some cases with its metal lens mount and sturdier construction. Focus accuracy is good, too.

The K100D Super boasts an impressive sounding 11-point AF system, though the majority of the sensors are placed centrally, so it doesn't quite match the convenience or efficiency of the Canon Eos 400D for snatching off-centre subjects.

Image stabilisation isn't visible in the viewfinder, as it is with rival lens-based systems, and neither will it work effectively during panning or on a tripod but, given the volume of legacy lenses in circulation, backwards compatibility with every Pentax lens made is a real plus.

From our tests with the kit lens fitted, we managed acceptably sharp shots at 1/15 sec at a focal length of 35mm (equivalent angle of view to 50mm on a 35mm camera), effectively two stops compensation. While rivals are introducing affordable IS lenses, to do the same with the D40 or Eos 400D, you will have to budget at the very least £160 (including VAT) for a new lens.

Enthusiasts will be pleased to see the expected semi-auto and manual exposure modes, but the K100D Super includes several shooting mode options for novices. As well as the expected handful of scene-based modes, the Pentax offers the Auto Picture mode option more usually found on the maker's point-and-shoot compacts. Based on metering and focus distance information, this system automatically selects from one of five scene modes, including Macro, Landscape and Portraits.

We were sceptical at first, but during our time testing, the Pentax nearly always chose the correct mode and the choice is neatly displayed as an icon in the viewfinder. With its pre-selected cap up to the impressive maximum ISO3200, we also like the Auto-ISO option allowing some user control over sensitivity (and noise), while allowing the camera to boost shutter speeds.
