The Pentax K-7 is a 14.6-megapixel digital single-lens reflex camera, announced on 20 May 2009.[1] This is the first new flagship model released by Pentax since its merger with Hoya Corporation on 31 March 2008. It was discontinued late in 2010 in favour of the K-5.

Features

[edit]

The Pentax K-7 was announced on 20 May 2009 and shipping began as of the first week of July 2009. The K-7 has the same pixel count as its predecessor, the K20D, but offers a significantly expanded feature set in a smaller body. New features include:[2][3]

  • body is still weather resistant like the K20D; however, it is now made of magnesium alloy, and it is now also low temperature resistant
  • a high-definition video recording function (30 frames per second at 1536×1024 resolution or HDTV (cropped))
  • TAv exposure mode: Time/Aperture Value: photographer sets his own desired shutter speed/aperture, while the camera adjusts the ISO accordingly to compensate exposure
  • in-camera high dynamic range imaging function to create one composite image from three images with different exposures
  • dedicated AF-assist lamp
  • in-camera electronic level that works with Earth's gravity, usable in total darkness too (a 1st by Pentax in any camera model from any brand)
  • automatic horizon correction
  • a new shutter rated for 100,000 actuations and capable of shutter speeds as fast as 1/8000 second
  • continuous shooting speed of up to 5.2 frames per second
  • a viewfinder with 100% field coverage
  • a new Natural-Bright-Matte III focusing screen
  • a new autofocus module
  • a 77-segment light meter
  • a newly developed DR II dust removal system
  • a 3″ LCD monitor with a wide angle IPS panel with approximately 921k dots
  • Face recognition in live view mode
  • a new-generation Shake Reduction mechanism which can compensate for rotational movement
  • lighter weight: the K-7 body weighs 55 g (7.5%) less than the K20D
  • very quiet shutter[4]
