Pentax K-5 Preview

by Hannah Thiem, September 2010 (updated February 2011)


Pentax announces the new K-5 DSLR today (September 20, 2010), a year and four months after the announcement of the K-7 (announced May 20, 2009). The K-5 is basically the same size and weight as the K-7 with a few new and improved features: higher megapixels, increasing from 14 to 16MP on the K-5, shoots video at 1080p/25fps (compared to 720p/30fps on the K-7), faster performance at 7 fps continuous shooting—albeit without a buffer so not sure how good of a performance it will actually deliver (vs. 5 fps on the K-7), focus and shutter speed priority during AF-C, and a newly improved 11 point SAFOX IX+ autofocus system (which we look forward to putting to the test). The US list price of $1599.95 would put it slightly below the Canon EOS 7D, (compare prices) (review), and slightly above the Nikon D7000, (compare prices) (review). Like all Pentax DSLRs, the K-5 features sensor-shift body-based image stabilization (up to 4 stops).

The Pentax K-5 key features include:

  • 16.3 MP CMOS sensor
  • ISO range: 80-12,800, expandable to 51,200
  • 1080p video at 25 fps with sound via built-in microphone or external 3.5mm stereo microphone jack
  • 11 point SAFOX IX+ autofocus system with dedicated AF assist lamp and light wavelength sensor
  • SDXC memory card compatibility
  • Focus and shutter speed priority during AF-C
  • fully weather sealed and coldproof design
  • High resolution (921,000 dot) 3" LCD
  • 100% viewfinder
  • HDMI output
  • Built-in electronic level with tilt scale display in LCD panel
  • maximum 1/8000 second shutter speed

Where to Buy

The Pentax K-5 digital SLR is available as a body kit only, or as a lens kit with the 18-55mm WR, from our partners. Help support photo.net by purchasing from them.

Official Pentax K-5 Press Release

PENTAX ANNOUNCES K-5 DIGITAL SLR FOR ADVANCED AMATEUR PHOTOGRAPHERS

GOLDEN, CO (September 20, 2010) — Pentax Imaging Systems has announced the Pentax K-5 digital SLR camera. The K-5 DSLR offers a true high-end prosumer design and features normally found only on the most costly of professional cameras. With exceptional reliability, user-friendly operation, and the compact, lightweight body of its predecessor, the Pentax K-7, the new K-5 offers several important and improved features.

The pro-oriented “prosumer” features that take this latest Pentax DSLR to the next level include:

  • High resolution 16.3 megapixel CMOS sensor.
  • Fast up to 7 FPS to capture fast action shots.
  • High sensitivity 80-12800 ISO range, expandable to 51200, with improved noise performance overall.
  • Widescreen 1080p HD video at 25 FPS with sound via built-in microphone or external 3.5mm stereo microphone jack.
  • Newly improved, highly responsive and accurate 11 point SAFOX IX+ autofocus system with dedicated AF assist lamp and light wavelength sensor.
  • Focus and shutter speed priority during AF-C.
  • Native support for both Pentax PEF and Adobe DNG 14 bit RAW files.
  • Improved in-camera HDR image capture with more blending modes and better image alignment for handheld HDR shots.
  • SDXC memory card compatibility (via firmware update).

Additional important features on the new Pentax K-5 digital SLR 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.

These improvements and features are a direct result of customer feedback provided to Pentax by dedicated “prosumer” Pentaxian shooters who have helped refine the K-5 to deliver a wide feature set and make it a perfect all-purpose camera for field or studio use. The K-5 is an excellent choice for advanced enthusiasts looking for a compact, yet highly advanced camera without spending thousands of dollars more. The Pentax K-5 digital SLR will ship in October 2010 as a body kit only for $1,599.95 USD or as a lens kit with the 18-55mm WR for $1,749.95 USD.

Pentax Imaging also announced the smc Pentax-DA18-135mm F3.5-5.6 ED AL [IF] DC WR lens designed exclusively for use with Pentax digital SLR cameras. 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 will ship in October for $529.95 USD. More information is available here: www.Pentaximaging.com.

    The specs look great. I suppose this has a APS-C format sensor. I wonder if it works with old film era Pentax lenses. If it performs as good as it sounds, I would definitely love to get this (if I ever manage to save enough money).

    I am a Pentax devotee since early 80s and the specifications sound great, probably one of the best products in the line of Pentax. Provided noise is at a minimum and focus track works as it is supposed to. When do you expect to carry a thorough review of this little gem?

    Chris Acosta , October 13, 2010; 08:07 A.M.

    I have a K7 which is a great camera but it doesn't have AF in movie mode! The K5 is crippled with the same flaw it's competition the Nikon D7000 is not. I've a feeling Pentax has made a fatal error unless this flaw can be corrected with a software update!

    Micha Goldfine , October 25, 2010; 04:56 P.M.

    it's not a "fatal" issue not to have a AF in movie mode. My Canon 7D doesn't have AF in movie mode and it's the benchmark camera people are referring to.
    I owned a Pentax and would love to own it again one day.

    Just go to the DxOMark Web page and compare the sensor performance with ANY other APS-C camera. (and quite a few FF)
    Remarkable!

    Hi, this is an excellent piece of equipment and you are going to love it . Fortunately i upgraded to this one from a pocket sized didgital camera and difference in mind blowing. You will find details review for Pentax k-5 here.

    Having had my K-5 for over half a year, and used it extensively (my wife has one, too), it seem to get the most out of the chip of all the cameras that use it: D7000, A55, NEX-5, to mention a few. So far among the better cameras I've used, and I do have experience from Leica (M3); Minox35 (the first real 35mm compact); various Canons, and Nikons (like the famous F-1); Rollieflex, Sinar, and Hasselblad (SWC & 500C)!
    The K-5 isn't the most flexible camera for movies, that's for sure, but most 'real' movies use a fixed camera (or nearly fixed), where different lighting conditions, from one end of take to the other, are rare. I don't think the pros will chose Pentax anyway, as it can't be controlled remotely in the way the really expensive DSLRs can.
