Reviews Word on the street for the Pentax K-5


8.3
Specifically, the K-5's ISO and exposure compensation controls are very well-placed for quick adjustment, and changing AF points is quick and easy too, simply by jogging left/right/up/down on the rear controller.

9.0
The K-5's LCD screen has a very high resolution of 920K dots, wide viewing angle and it remains visible outdoors in all but the brightest of conditions, making it one of the best LCD screens that we've seen on a DSLR.

8.0
The Pentax K-5 is a highly-specified and immensely enjoyable camera to use, and one which can easily withstand an array of photographic challenges.

What People Are Saying Give it to me straight

Lens

In comparison with SDM-equipped optics such as the DA* 16-50mm f/2.8, the 18-55mm kit lens with which the Pentax K-5 is available delivers a reasonable performance overall, focusing only marginally slower in good light and takes just a little more time to confirm focus, once it has reached a rough approximation.

Unfortunately, as with most of the other DSLR cameras on the market that offer video recording, it's not the most user-friendly experience, with no handy one-touch recording, reliance on manual focusing, inability to change the aperture or shutter speed during recording, enormous file sizes that quickly fill your memory cards, and the inherent handling quirks of the DSLR format.
by Photography Blog (Nov, 2010)
Larger sensors have greater light-gathering abilities, helping in particular in low-light situations, but cost much more to manufacture and require bulkier lenses and camera bodies.

Sensor

As usual, there is a clear difference between RAW and JPEG output from the K-5, and as we'd expect, a lot more detail can be coaxed from the RAW files.
by DPReview (Dec, 2010)
On the front of the camera body is the RAW / FX button, which instantly sets the image quality to whichever RAW format is selected in the menu system (either Pentax's PEF format or Adobe DNG), useful if you are shooting in JPEG and want to quickly switch to RAW mode for a particular image.
by Photography Blog (Nov, 2010)
This feature is an extra benefit of the K-5's sensor-shifting Shake Reduction (SR) system which automatically moves the sensor to compensate for accidental camera movement that can blur images.
by TechRadar (Aug, 2012)

Focus

Those tests, it should be noted, only measure the sensor, not countless other important camera details such as price, autofocus, lens and accessory selection, durability, performance, and user interface.
by c|net (Nov, 2010)
Autofocus acquisition is extremely fast and positive, with both conventional screw-driven AF lenses and SDM (ultrasonic-type) optics.
by DPReview (Dec, 2010)
While the speed at which this happens increases the live view system's usability in different situations, occasional mis-focuses and problems with finding focus mean it can't always be relied upon when lighting conditions aren't optimum.
by TechRadar (Aug, 2012)

Image quality

Detail capture is excellent (although you'll have to put some very good glass on the front of the camera to get the full benefit) and dynamic range is wide.
by DPReview (Dec, 2010)
Image quality is now up there with the best of its competition, and all of the K-5's key systems are reliable and effective.
by DPReview (Dec, 2010)
Although the K-5 can now microalign images before combining them, allowing hand-held HDR shots to be taken, for best results it's important to always use a tripod to prevent camera shake from blurring the HDR image, and it doesn't work very well for moving subjects.
by Photography Blog (Nov, 2010)

Iso

Things fall apart a bit above ISO 6400, but careful tweaking of the NR settings (or even better, shooting in RAW mode) will enable you to get acceptable results out of the K-5 even up to ISO 25,600.
by DPReview (Dec, 2010)
Set to 'fast' the K-5's automatic ISO control aims to deliver shutter speeds significantly higher than are required simply for avoiding camera shake, so a minimum of 1/80sec at 18mm, and 1/400sec at 135mm.
by DPReview (Dec, 2010)
Noise is well controlled by the Pentax K-5, starting to appear at ISO 1600 and becoming more easily detectable at the faster settings of ISO 3200 and 6400 when viewing images at 100% magnification on screen (particularly in the RAW files).
