Reviews Word on the street for the Pentax K100D

That bulk is reflected in the build quality.

With a nice combination of auto and manual features, the Pentax K100D offers enough features to quench both experienced and amateur photographers.

The blocky typefaces and kindergarten colours really undermine this camera's quality feel.

What People Are Saying Give it to me straight


Like the *ist DS2, the built-in pop-up flash has a guide number of 15.6 at ISO 200, but the angle-of-view coverage has been widened to 18mm to match the widest angle-of-view of the lens included in the kit version: the Pentax DA 18mm-to-55mm (35mm equivalent) f/3.5-to-f/5.6 zoom lens.

This combination means that assuming the 'input image' is sharp (good lens and/or stopped down slightly) you're going to get a great detailed image.
by DPReview (Dec, 2006)
The 18-55mm kit lens has good and bad points, too.

Like most DSLRs the K100D can shoot in RAW mode, as well as the usual JPEG, but unlike some models it can’t shoot RAW + JPEG, which will put some enthusiast users off.

1/350th, f/9.5, ISO 800 At 800 ISO there is a slight hint of colour speckling in the dark and mid-tone areas, but the image is still quite usable.
by TrustedReviews (Feb, 2011)
The unwashed, pixel-obsessed masses will no doubt complain about the 6.1-megapixel CCD sensor, but it's still more than enough for letter-size prints, which should be plenty for most casual shooters.

Image stabilization

One addition here is obviously the Shake Reduction switch.
by DPReview (Dec, 2006)
It’s worth noting that none of these competing cameras have shake reduction systems.
by TrustedReviews (Feb, 2011)
On the other hand, if you're really looking to save money, and shake reduction doesn't float your boat (though it probably should), then you can always step down to Pentax's K110D, which is the same camera without the shake-reduction feature.

It’s an option to change between auto AF area, manual AF area and centre spot AF, so why not just label it “AF area?
by TrustedReviews (Feb, 2011)
You can choose from Auto AF-point selection, manual point selection or center point only.
by DPReview (Dec, 2006)
Shooting in continuous mode, you can shoot as many as five images before the buffer fills.

Image quality

In addition to the Tone baseline you can also adjust Contrast, Saturation and Sharpness.
by DPReview (Dec, 2006)
Despite the overcast conditions, the K100D has produced a nicely balanced shot with good contrast and very natural colour balance.
by TrustedReviews (Feb, 2011)
Maybe it's a sign of the sensor's age (in development terms) but using the K100D without noise reduction for a typical thirty second exposure will lead to a liberal sprinkling of 'hot pixels' all over the image, some more pronounced than others.
