On September 20 2010, Pentax announced the new K-5 DSLR camera
. The K-5 DSLR features a 16.3 Megapixels sensor, 7fps burst shooting, ISO 80-51200, full 1080 HD at 25fps, faster autofocusing, upgraded HDR, and a dustproof, weather-resistant and cold-resistant construction. Additional important features on the K-5 include:
- A fully weather-sealed and coldproof design.
- A large 3-inch LCD with 921,000 dots of resolution.
- Durable magnesium alloy that surrounds a rugged stainless steel chassis.
- Highly accurate 77 segment metering system.
- Pentaprism viewfinder with 100% field of view and 0.92X magnification.
- PENTAX body-based Shake Reduction (SR) stabilization system that works with every PENTAX lens ever made.
- A maximum 1/8000 second shutter speed.
- HDMI port outputs high-definition images and video (and sound).
- A wide range of in-camera image processing and special effects filters.
- Customizable RAW/Fx button.
- Built-in electronic level with tilt scale display in LCD panel.
The K-5 as a body kit only is listed for $1,599.95 or as a lens kit with the 18-55mm WR for $1,749.95. Pentax also announced the smc PENTAX-DA18-135mm F3.5-5.6 ED AL [IF] DC WR lens. This interchangeable zoom lens features a simplified weather-resistant construction and extra-smooth autofocus operation using a built-in motor, in addition to its high 7.5X zoom ratio. This new lens is listed for retail at $529.95. Here's the summary of review by PhotoReview Australia, giving the camera a rating of 9 out of 10:
"Pictures taken with the test camera were sharp and the colour balance in shots appeared very close to the observed scene with the default Bright Custom Image setting. The Natural setting reduced overall contrast slightly and delivered more subdued colour rendition. The review camera's dynamic range appeared able to handle most types of lighting with the default settings. The default level of sharpening appeared low (a judgment backed by our Imatest tests), minimising the incidence of sharpening artefacts and providing scope for post-capture adjustments. It was impossible not to be impressed by the camera's performance at high ISO settings, regardless of exposure lengths. Little noise could be seen in indoor shots in low light levels at sensitivity settings up to ISO 1600, where noise was only evident when images were magnified to 100% on-screen. Thereafter, noise became gradually more obvious at this magnification, although shots taken with the highest ISO setting (equivalent to ISO 51200) where able to be printed at A4 size with minimal noise visible. (Sharpness was very slightly reduced.) Long exposures at night were almost noise-free up to ISO 6400, with a gradual increase in the visibility of noise thereafter. Interestingly, although noise was obvious in exposures of between four and eight seconds at ISO 51200, image quality was no worse than we have seen from many cameras at ISO 6400.
Imatest confirmed our subjective assessments and showed only a slight decline in resolution as sensor sensitivity was increased, particularly with raw files. JPEG resolution fell off more sharply but the difference between the ISO 25600 and ISO 52100 settings was less than we found with raw files at the same sensitivity settings. Imatest also showed resolution to be slightly below expectations for a 16-megapixel camera. This was true for both JPEGs and DNG.RAW files converted into 16-bit TIFF format with Adobe Camera Raw with no additional processing. Slight edge softening was detected across the kit lens's aperture and focal length range. Best performance was between f/5 and f/8 for shorter focal lengths and around f/6.3 at the longer end of the zoom range. Lateral chromatic aberration remained consistently within and below the 'low' band and we found no obvious coloured fringing in test shots. In the graph below, showing the results of our Imatest tests for chromatic aberration, the red line marks the border between 'insignificant' and 'low' CA, while the green line shows the edge of the 'moderate' CA band. Long exposures were more noise-affected than flash shots, regardless of noise-reduction processing. Dark-frame subtraction processing roughly doubles image capture times when slow shutter speed noise reduction is engaged and users have no control over the degree of processing applied.
Autofocusing was fast (although not spectacularly so) and accurate under most conditions although there was a noticeable slowing down in the movie mode. The lens was moderately flare-resistant, despite the lack of a lens hood (a necessity for strong backlighting). Video quality was significantly better than we found with the K-7 but, again, not spectacular. The camera defaults to the Natural Custom Image setting in this mode, which reduces contrast and saturation slightly. Users who prefer 'punchier' video clips can select any of the other options by pressing the right button on the arrow pad. We found no instances of the 'rolling shutter' effect that is common with CMOS sensors and no signs of the coloured banding encountered with the K-7. Soundtracks were surprisingly clear, given the tiny, single-hole microphone. However, they lacked 'presence' and wind noise was picked up in outdoor recordings. (You can attach a stereo microphone to rectify these deficiencies.)"... [Source

"The model without an anti-aliasing filter is aimed at studio photographers who may want higher resolution. Anti-aliasing is a way that camera vendors handle an inherent problem of digital photography. The pixels that make up the image can make diagonal lines look like a series of steps when enlarged. But if the lines are parallel and small enough, the image..." More »

"Thanks to the sensor we liked so much in the K-5 and Nikon D7000, the Pentax K-5 II still turns out excellent images with a wide dynamic range and low noise, while maintaining good shadow and highlight detail. At ISO 3200 and above we begin to see processing applied before Raws are saved, resulting in an apparent improvement in our measured noise graphs, bu..." More »

"I always get antsy when I try a new DSLR system out, mostly because I have been using the Canon EOS system for over a decade now and I'm just used to it. That being said, when a new camera is in my hands and it's not at all complicated for me to acclimate to, I get pretty excited. The Pentax K-5 II and IIs felt very comfortable in my hands (if a bit small)..." More »

"The K5-II put in an excellent performance under studio lights, with extremely sharp detail at the centre of the frame. As is always the case in the still-life test, it was set to full auto so it could choose its own shooting settings. It opted for 1/60 second, ISO 100, at f/5.6. There was no grain in the image, and sharp contrasts, such as where black met w..." More »

Verified Purchase ( I've been using this camera constantly since I received it, around 2010 and I love it. It takes great photographs and the back log of amazing manual lenses is a huge plus for me. within the past 6 months there has been a very limited case of double shutter exposure, but I haven't been able to reproduce the effect, so it's just a general annoyance...

One of hidden gems, Sun Kim - Jul 17 2014
Verified Purchase ( Feels top-notch in my hands. Slightly heavy, whispering shutter sounds. Single battery is enough for 1-2 day shooting. Everything seems designed by professional standards. I have used this camera for about 3 months. Great image quality, speed! I purchased it from EZCORP. They sent me the free gift together, a professional camera bag with no cost....
