Reviews Word on the street for the Pentax K-m

The K2000 is probably the most accessible DSLR Pentax has yet made, with its small size, refined interface and very reasonable balance of features and price.

The K-m has a fairly good five-point AF system, with a choice of wide area or centre spot focusing, and it does focus quickly and accurately in most lighting conditions, but for shots where the main subject is not in the centre of the frame, or where a precise focus point is desirable such as macro photography, it would be an advantage to know exactly where the camera is focusing.

The K2000 also has Pentax's Sensitivity Priority mode, which allows you to select ISO sensitivity while shutter speed changes and aperture remains fixed; this is especially useful for homing in on appropriate settings for low-light shooting.

This is a great camera for shooting JPEGs because you can experiment with all these colour modes knowing that you're scarcely losing anything in quality by not shooting RAW.

What People Are Saying Give it to me straight


Because Pentax's anti-shake is built into the body, it should offer shake-reduction with any lens, whereas Nikon and Canon favour stabilisation systems built into the lens instead.
by TechRadar (Dec, 2008)
You'd have to invest in one of Pentax's more expensive zooms to get round this (the 17-70mm f/4, for example), but this will double the price.
by TechRadar (Dec, 2008)
We have tested each of these lenses and their performance is all-but identical at the apertures used (though the Zuiko is more consistent into the corners of the frame).
by DPReview (Jan, 2009)


Whatever changes the system is making, they're included in the RAW file (probably via a metadata tag) in such a way that they can be interpreted by a variety of RAW converters, so you are not tied to Pentax's own software to see the benefit in RAW.
by DPReview (Jan, 2009)
It has a menu button and D-pad, with secondary functions on the D-pad buttons for white balance, ISO setting, flash mode and self-timer/drive mode.
by TrustedReviews (May, 2011)
Which makes the dissappointing JPEGs even harder to understand: if the sensor is capturing at least as much detail as the Canon, why does it need such crude sharpening to convey that detail in JPEG?
by DPReview (Jan, 2009)


It uses the K200D's sensor but comes with a simplified control layout (geared towards users coming from compact cameras) and a less sophisticated AF-system (5 points vs 11 on the K200D).
by DPReview (Jan, 2009)
It is possible to focus on specific points by using the centre spot AF and re-framing, but other entry-level SLRs have selectable AF points with illuminated viewfinder targets.
by TrustedReviews (May, 2011)
You don't get illuminated AF points, alas, and although the K-m's 5-point AF system is a little more sophisticated than the 3-point systems in the Nikon D60 and Olympus E-420, say, there's very little advantage if the AF points aren't highlighted in any way.
by TechRadar (Dec, 2008)


From looking at the camera's RAW output, it's obvious that it is capturing at least as much detail as its peers, yet this detail isn't being expressed by its internal JPEG engine.
by DPReview (Jan, 2009)
While it's not uncommon for RAW conversion to be able to produce better results than the camera's JPEGs, it's uncommon for the gulf to be so wide.
by DPReview (Jan, 2009)
but it's pretty easy to clean it up in either the supplied Silkypix software or Adobe Camera Raw.
by TrustedReviews (May, 2011)


While you should probably stick with ISO 400 and below for general shooting, I found photos generally usable as high as ISO 1,600, depending upon output size and content.
by c|net (Jun, 2009)
Even 3200 ISO isn't a complete disaster, as long as you don't want to blow the pictures up too much.
by TrustedReviews (May, 2011)
At ISO 1600 it is able to match its peers for detail.
