Pentax K-30 Digital SLR Review
Joshua Waller reviews the new weather sealed Pentax K-30 Digital SLR with 16.2 megapixel sensor and 6fps continuous shooting.
It's been nearly 2 years since the last new Digital SLR introduced by Pentax, with the Pentax K-5 announced in September 2010, and since then, a lot has happened. Pentax was sold by HOYA to Ricoh to become Pentax RICOH Imaging. Pentax also announced and released two new mirrorless cameras, the compact camera sensor based Pentax Q with all new Q-mount, and the APS-C sensor Pentax K-01 with K-mount. The Pentax K-30 features the same APS-C sensor made by Sony as the Pentax K-01, and with a weather sealed body sits somewhere in between the Pentax K-r and Pentax K-5. It's also the last HOYA developed camera.
The Pentax K-30 is described as a mid-level Digital SLR, designed to be the perfect outdoor camera, with a weather sealed body and rubber grip it should work in a variety of situations, from hot sunny weather to the much more common rainy day. The camera features Pentax' Shake Reduction (SR) sensor to enable sharp shots even when the skies are clouded over, this has the benefit of working with any lens attached to the camera, for both stills and video.
The camera records RAW photos as AdobeDNG files meaning that it will work straight away with Adobe's popular photo editing applications such as Lightroom and Photoshop.
A built in electronic level and horizon correction can help produce perfectly level landscapes with the horizontal level visible in the optical viewfinder, and both horizontal and vertical visible on the rear screen.
On the main mode dial, the camera features: AUTO, Video, P, Sv (Sensitivity priority), Tv (Shutter priority), Av (Aperture priority), TAv (Shutter and Aperture priority), Manual, Bulb, User2, User1, and Scene. Unlike the Pentax K-5 the K-30 does not feature a mirror lock up mode, except for sensor cleaning.

Looking at the specifications of the Pentax K-30 compared to the K-r and K-5, there is not a huge difference between the cameras, yet the K-30 offers weather sealing, upgraded video, focus and metering at a more entry level price.
Handling - The Pentax K-30 has a large handgrip with a deep recess for your fingers and on the left of the camera body is another rubberised area for additional grip. This is where the rubber stops, with the rear of the camera lacking a rubber thumb rest instead featuring a dotted area with little grip (if they were raised dots they would have provided more grip), and on the white and blue versions of the camera, the glossy finish doesn't help with grip. Instead the thumb can grip onto the corner of the camera that sticks out noticeably above the SD card cover. On the left and right surrounding the lens mount is a set of ridges which could be used as another point of contact for additional grip, particularly if wearing gloves, however without gloves they weren't very comfortable to hold.
The body of the camera feels extremely solid with a reassuringly rigid construction. The battery compartment, SD card slot cover and pop up flash are made out of thick plastic, with metal hinges and their own weather seals. SD card removal can be a bit tricky, but once you get used to it becomes easy enough. The ports (video/USB/remote) are covered with thick rubber covers that fit firmly into place. Metal strap loops are built into the body of the camera. The optical viewfinder is bright and clear, with a comfortable rubber surround and dioptre adjustment.
The camera has a number of useful buttons giving you quick access to common settings, without the need to delve into the menus, with further buttons on the left of the camera letting you set the focus mode, RAW/fx as well as pop up the flash. This is a mechanical button so the flash can be opened with the camera still switched off. Pressing the INFO button brings up the rear control panel where photo settings can be altered quickly. The RAW/fx button can be customised to set: File format, exposure bracketing, optical preview, digital preview, composition adjust, and AF active area. AF/AE-L can be customised to: Enable AF1, Enable AF2, Cancel AF and AE lock for both photo and video.
Menus – The Pentax menus will be familiar to anyone who has used a Pentax Digital SLR over the last few years, with clear separated areas (Photo, Video, Playback, Setup and Custom). The first item in the photo menus is the custom image setting where you can choose from 11 presets, as well as customise each one. When you customise these you can set saturation, hue, high/low key, contrast and sharpness, as well as preview each preset. The camera features copyright information that is embedded into the EXIF information for each photo when enabled. The custom menus have a total of 23 additional settings, each of them numbered, including expanded ISO range (3), AF fine adjustment (22), Save menu location (20), AWB in tungsten light (11, subtle/strong), to name a few. Pressing the INFO button gives you a control panel on the back screen of the camera letting you change settings quickly and easily. The menus can be viewed above in the menu walk-through video, to read through the options the video can be paused if needed.
Battery life - CIPA test results say the battery should be good for 410 shots. We were able to take over 600 shots before the battery went flat. This is impressive, although the majority of our shots were taken without flash. The K-30 can accept AA batteries with an optional AA battery holder (D-BH109).
Speed - We took a number of shots to test the camera's responsiveness, from switch on to first photo, shot to shot, focusing speed etc. We take a number of shots and then use the average to ensure accurate and consistent tests, making it easy to compare with other cameras.

Focusing and continuous shooting was very quick with impressive focus speeds when shooting using the optical viewfinder. Live view shutter response and focus speeds are noticeably slower, and therefore it's best to avoid using live view unless using the camera for still life or static subjects, live view focusing can also make the camera seem much louder due to the focus hunting more. The camera will shoot at 6fps in JPEG or RAW shooting modes, with the number of shots before slowdown being quite impressive. Switch on time is quite rapid. Shot-to-shot is excellent, although slower with flash.

Contrasty | 1/200 sec | f/7.1 | 37.5 mm | ISO 100
Portrait Flash | 1/40 sec | f/5.6 | 55.0 mm | ISO 800
Sample Photos - Colour reproduction is very good with strong saturation and particularly impressive flesh tones. Detail can be very good. Exposure and focus are reliable, with the camera producing bright punchy images. Shake Reduction allows shots to be taken at shutter speeds as slow at 1/10 with sharp results for a good number of the shots.
Pentax K-30 Lens test images
Pentax K30 Wide | 1/250 sec | f/7.1 | 18.0 mm | ISO 100
Pentax K30 Zoom | 1/250 sec | f/9.0 | 55.0 mm | ISO 100
Pentax K30 Trees | 1/60 sec | f/4.0 | 18.0 mm | ISO 100
Macro | 1/5 sec | f/8.0 | 55.0 mm | ISO 400
Lens Performance - Dynamic range is very good with a number of options to increase or adjust the levels recorded (examples are shown below). The 18-55mm AL WR lens appears to be resistant to lens flare, although some barrel and pincushion distortion is visible at the wide and telephoto ends of the lens respectively. This can easily be resolved by switching on lens distortion correction in the camera. Purple Fringing was visible in areas of very high contrast, but chromatic aberrations were generally very low (again CA correction can be switched on in camera). The kit lens is capable of quite close focus at the telephoto end, producing decent macro shots.

1/800 sec | f/5.6 | 40.0 mm | ISO 25600
ISO Noise Performance - Noise is very low from ISO100 through to ISO400. At ISO800 / ISO1600 noise starts to creep into the image. At ISO3200 noise becomes more noticeable again. At ISO6400 noise grain becomes more prominent although lighter colours are quite clean. Noise begins to dominate the image at ISO12800, and it's at this setting that you may decide that it's the highest ISO setting you want to use. ISO25600 shows the highest levels of noise, as it expected, however colour saturation is still very good. Images taken with the smc PENTAX-DA 40mm f/2.8 Limited lens.
Pentax K-30 White-balance test images
AWB Tungsten | 1/25 sec | f/2.8 | 28.0 mm | ISO 100
Tungsten Preset | 1/25 sec | f/2.8 | 28.0 mm | ISO 100
AWB Fluorescent | 1/6 sec | f/2.8 | 28.0 mm | ISO 100
Fluorescent Preset | 1/6 sec | f/2.8 | 28.0 mm | ISO 100
White Balance Performance - AWB (Auto White Balance) produces a warm image under tungsten lighting - this was with correction set to subtle in the custom menu. The tungsten preset gives a much more neutral result. AWB under fluorescent lighting gives a slightly amber cast to the image. Using the fluorescent preset (of which there are four) produces a more neutral result. Images taken with the smc PENTAX-DA* 16-50mm f/2.8ED AL [IF] SDM.

Drive HDR-1 / Auto | 1/60 sec | f/11.0 | 18.0 mm | ISO 200
Other sample photos - Highlight Correction has three options: Auto, On, and Off, while Shadow Correction has five options: Auto, Low, Mid, High, and Off, both of these settings can greatly improve dynamic range recorded in an image. Alternatively the camera has a built in HDR mode with five options: HDR Auto, HDR1, HDR2, HDR3 and off - the HDR mode takes 3 photos at different exposures and combines them in camera to give an image with much higher dynamic range.

ISO can't be adjusted unless you are in full Manual mode. In manual mode shutter speed and ISO can be adjusted while recording. Exposure compensation is available while recording video in any mode. White balance can be selected prior to recording but not during. SR is very effective at stabilising hand-held videos.
Value For MoneyThe Pentax K-30 is available for £599 body only making it excellent value for money for a weather sealed Digital SLR. Alternatives to consider include the Nikon D5100 (£429 body only), Canon EOS 650D (£699 body only), Sony Alpha A57 (£519 body only) / A65 (£685 body only), and the Pentax K-5 (£693 body only), although only the Pentax K-5 has weather sealing. For other weather sealed cameras, the next closest priced model is the Sony Alpha A77 (£909). You'll also need to buy a memory card and a case or bag to keep your camera safe and protected - have a look at our complete guide to camera bags.
Images from the K-30 have excellent colour and dynamic range, with a number of options to tailor the results to your liking whether you want to adjust the colour or the dynamic range recorded. Detail can be very good with the right lens, and the Pentax K mount ensures that there is a vast array of lenses to choose from. Currently, while more advanced photographers may be better off with the Pentax K-5, this would make an excellent upgrade from the Pentax K-r or a great choice for someone looking for a camera that can withstand the great British weather, while still being able to shoot great shots.
