Pentax K-5 Review: A Weather-Sealed DSLR for Around $200

Photo quality and color

The 16.3MP APS-C sensor remains the strongest reason to consider this camera. It gives you enough resolution for everyday photography, sharing, printing, and moderate cropping without creating unnecessarily huge files.

In my use, the K-5 produced photos and colors I liked. That is the main reason I would consider one despite its slower controls and autofocus.

The standard sensitivity range is ISO 100 to 12800, with expansion available from ISO 80 to 51200. The video includes samples across the range so you can judge the noise for yourself rather than relying on a single universal cutoff. Your tolerance will depend on the scene, output size, and how much detail you need to preserve.

Body stabilization

The K-5 uses sensor shift Shake Reduction, so stabilization is built into the body instead of depending on a stabilized lens. Pentax rated the system for up to about four stops of compensation, although the real benefit depends on the lens and shooting conditions.

For photography, that can help you use a slower shutter speed while still getting a sharp, usable image. It is especially valuable with older or affordable K-mount lenses that do not have their own stabilization. You still need an appropriate shutter speed for a moving subject, but the system can reduce blur caused by your hands when the subject itself is still.

The K-5 can also apply Shake Reduction during movie recording. That does not turn its dated video mode into a modern video system, but it is a useful feature to have in a camera at this price.

Build and handling

The K-5 feels substantial. Its exterior uses magnesium alloy over a stainless steel chassis, and Pentax built weather resistance into the buttons, dials, seams, and other vulnerable points. Pair it with a compatible weather resistant lens if you want the most complete protection.

I like the deep grip and find the camera comfortable to hold. The controls and top status screen reinforce the impression that this was designed as a serious enthusiast DSLR, not a basic beginner body.

That durability comes with weight. The body alone is about 660 g, while the ready to shoot weight with the D-LI90 battery and an SD card is about 740 g. I personally do not mind carrying it, but it is bulky beside a mirrorless camera and is obviously not a pocketable option.

The rear display is a fixed 3 inch LCD. It does not tilt, articulate, or respond to touch. You also get one SD card slot on the side, which is more convenient to reach than a slot tucked into the battery compartment.

Autofocus and shooting speed

The K-5 can shoot at up to about seven frames per second, which is still a respectable burst rate. The autofocus is the limiting factor. In use, the camera feels slower and clunkier than the headline burst number suggests.

That makes it better for portraits, landscapes, architecture, products, and other subjects that give you time to work. For sports, wildlife, children, or unpredictable action, a burst of frames is not much help if the camera cannot keep focus where you need it.

The K-5 feels substantial in the hand, much like the Nikon D7100. Choose based on the lenses and controls you need, as well as the body’s stabilization and weight.

Video and audio

The K-5 records Motion JPEG video at up to 1920 x 1080 at 25 fps. I would not buy it primarily for video.

The fixed screen makes awkward angles and recording yourself difficult, and autofocus does not operate continuously while a movie is recording. Shake Reduction can help steady the frame, but it does not solve the limitations in focusing, workflow, or image quality.

The K-5 has a 3.5 mm external stereo microphone input and a built in monaural microphone. The input is useful for occasional clips, but it does not address the fixed screen or dated focusing and recording workflow.

Pentax lens options

The K-5 uses the Pentax KAF2 bayonet mount and supports several generations of K-mount lenses. There are affordable lenses available, and the in body stabilization makes older glass more useful.

The selection is still less broad than the ecosystems surrounding mainstream Canon, Nikon, and Sony bodies, especially when you compare brands, focal lengths, and used prices. Before buying the camera, price the lens you actually need. A low body price is not a bargain if the right lens is difficult or expensive to find.

This matters most if you expect to build a large system. If you only need one standard zoom and perhaps a prime or telephoto lens, the smaller catalog may not be a major problem.

Body price and complete kit cost

The review was made when bodies could be found around or below $200. Treat that as a value target, and compare current listings by condition and what is included.

Near $200, I like the K-5’s photo quality, stabilization, and rugged handling. Closer to $300, compare newer bodies and complete kit costs. Check the shutter count, controls, seals, sensor, included D-LI90 battery and charger, and return terms. Price the lens you need before buying the body.
