Those who wish to nit pick will find some pixel fringing evident around the branches top of frame, but overall this is very good showing indeed.

Reviews Word on the street for the Pentax K-r

For some users the faster, but more expensive SDM lenses might be a sensible investment, as with the K-r's excellent continuous shooting speed and the right set of lenses the camera could be a good option for sports/wildlife/action shooters on a budget.

The Pentax K-r lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well, which is very good news if you are seriously interested in night photography.

Sharpness is maintained when shooting handheld at maximum telephoto setting.

Certainly you lose nothing in terms of image quality – we were delighted with the high ISO performance of the K-r, and the kit lens is pretty impressive.

What People Are Saying Give it to me straight


Very little about the K-r build quality feels compromised - it even has a sturdy memory card door (typically a weak-point of entry-level DSLRs), metal lens mount and metal tripod mount in-line with the lens.

Pentax lens system is limited.
by TechRadar (Nov, 2010)
In this mode the user sets the desired sensitivity setting while the camera selects what it calculates are appropriate aperture and shutter speed settings.
by TechRadar (Nov, 2010)


As you can see the visual differences are limited to the AF-assist light (underneath the mode dial), a boxier prism (presumably to accommodate the visible AF points) and more angular top plate, accompanied by a larger, higher resolution screen on the K-r.
by DPReview (Mar, 2011)
Apart from this (for some users at least) quite important improvement the SAFOX IX system's AF points are also spread more widely across the frame than on the previous cameras.
by DPReview (Mar, 2011)
None of the DSLR contrast detect AF systems on the market are really very good, but the K-r's is one of the better ones.
by DPReview (Mar, 2011)


It's a step up model from a totally entry level DSLR with its high-resolution screen, 11 focus points, and fast performance, but yet it lacks Full HD video (only HD Ready) and has a lower-resolution sensor than some other mid-range models.
by TrustedReviews (Jun, 2014)
At the same time the competition has moved on and the upper entry-level models from other manufacturers offer higher sensor resolutions, better video-capture and similar specifications at a comparable price point.
by DPReview (Mar, 2011)
The Pentax K-r has 3 different JPEG file quality settings available, with Best being the highest quality option, and it also supports RAW (Pentax's PEF format and Adobe DNG).
by Photography Blog (Nov, 2010)


It also comes with a 1080p full HD video mode and a 18MP nominal resolution in combination with a fairly strong feature set.
by DPReview (Mar, 2011)
It offers 1080p AVCHD video, a 14MP sensor, a swivel-screen and at seven frames per second ever faster continuous shooting than the K-r.
by DPReview (Mar, 2011)
Footage is not quite as detailed as the 1080p output of some of the higher-priced competitors but in-line with other 720p video-DSLRs.

Image quality

The following were all shot as maximum resolution, Fine quality JPEGs under available natural light, with automatic white balance and the Pentax's 'Natural' custom image mode deployed to ensure a level playing field.
by TrustedReviews (Jun, 2014)
The K-r's performance in low light and at higher sensitivities is very good.
by DPReview (Mar, 2011)
It's noticeably quicker now, there's less hunting and the performance in low light is better.
