Pentax K-30

The Pentax K -30 is one of the Japanese manufacturer Pentax digital SLR, which was introduced in May 22, 2012 as the successor of the Pentax Kr and came on the market in July 2012. The central component is developed by Sony IMX071 CMOS sensor, in which the A / D converter are accommodated for signal conversion directly on the chip. It offers an effective resolution of 16.28 million pixels to 372 mm ² and a maximum image size of 4928 × 3264 pixels.

Important features

The sensor size 23.7 mm × 15.7 mm (APS -C ) corresponds to an elongation factor for lenses of about 1.54 compared to the small format.

The image stabilization system Shake Reduction has an efficacy from 2.5 to 4 LW. The stabilizer is built into the housing and thus works with all lenses; be corrected by translational and rotational camera shake elle.

The power can be supplied with a rechargeable lithium -ion battery of the type D- LI109, with four NiMH rechargeable batteries or four AA batteries in the design.

The housing is sealed with 81 seals against water spray, humidity, sand and dust.

Weight is without battery and memory card 590 g, 650 g ready The dimensions of the camera are 128.5 mm × 96.5 mm × 71.5 mm (W × H × D).

In video mode HD is the resolution of Full HD 1920 x 1080 (16:9 ), 30 B / sec / 25 B / sec / 24 B / sec, 1280 x 720 (16:9) 60 frames / sec / 50 B / sec / 30 B / sec / 25 B / sec / 24 B / sec, 640 x 480 ( 4:3) 30 B / sec / 25 B / sec / 24 B / sec stored, the format videos Videformat MPEG -4 AVC / H.264

Copyright information and the name of the photographer can be embedded by the camera directly into the EXIF data of the images.

The camera has an integrated HDR mode, with which can also accommodate hands-free HDR images. The camera takes three images at -3, 0, 3 EV and automatically sets up the images on each other. The strength of the effect is automatic and selectable in four steps.

Built is a dual-axis electronic level, which helps in the orientation of the camera. It can also be used for automatic alignment of the images while recording by the movably mounted image sensor.

For all lenses, the Pentax DA series (except Fisheye 10-17 mm), DA *, DAL, D FA, each identical to the Samsung D - Xenon and D- Xenogon and three FA Limited lenses ( 31mm 1.8, 43 mm 1.9 and 77mm 1.8 ), the distortion and lateral chromatic aberration ( lateral chromatic aberration ) have to be corrected when recording from the camera. This has an effect on the required to save computation time.

Bayonet and Lenses

The KAF2 bayonet is backwards compatible with all K- mount lenses that have been built since 1975. Contacts for controlling lenses with focusing via ultrasonic motor are available. In addition, the K-30 has a housing internal autofocus motor which drives Pentax AF lenses without own motor. The Abblendmöglichkeit is the depth of field preview. For the digital image Preview a sample image on the monitor will be displayed and can be saved.

Technical Description

The light sensitivity can be set from ISO 100 to 12,800 ISO automatically and manually, in Enhanced mode from ISO 100 up to ISO 25600; the intermediate values ​​can be set in half or third stages. Shutter speeds are adjustable from 1/6000 to 30 seconds, plus there is long-term exposure (B) and flash sync speed (X) 1/180 second. The images can in two formats JPG ( 3 grades ) and the manufacturer- independent DNG format are stored with 12 bit resolution. For each ISO value, the amount of noise reduction can be adjusted individually.

The exposure is determined in 77 fields that can be used as matrix, center-weighted or spot oriented evaluated. Corrections are possible in the range of ± 5 EV in 1/3-stop increments.

The glass pentaprism viewfinder features a 0.92 -times magnification, 100 % field of view and interchangeable focusing screens.

The LCD display has a size of three inches, a resolution of 921,000 (640 × 480 RGB) pixels and a viewing angle of up to 170 °. About the monitor can be viewed in Live View mode, and in addition to the normal phase AF with contrast autofocus - be focused - it either with or without face detection; in both modes is possible an assessment of the depth of field. The monitor is calibrated in 49 steps.

The A / D converter operates with 12 bit color depth. There are a fine correction of the white balance presets and several presets for manual white balance. Five user programs are used to store and quickly recall a user-defined camera configuration.

Bracketing with three images are possible, while different parameters can be varied: exposure time, white balance, saturation, contrast and sharpness. In addition, you can also make multiple exposures. The captured images can be edited through nine filters.

The burst speed is a maximum of six frames / second (Hi) or 3 frames / second ( Lo). Hi -Mode can be recorded continuously at maximum speed up to 23 images in JPEG and 8 images in RAW mode ( raw format ), then the camera shoots at a reduced speed (depending on the maximum continuous writing speed of the memory card).

The 11- point autofocus system ( SAFOX IXI ) is equipped with nine cross-type sensors. By the AF fine adjustment is front or back focus problems of individual lenses can correct.

There are three focus modes available: AF-S (single -servo AF), AF-C (continuous autofocus ) and manual. For the autofocus can all eleven, the middle five, the central or be selected from the eleven sensors. In very low light the camera to focus turns to a green LED illuminator.

The flash control an external flash can wirelessly via the built-in flash. There continues to be a X-sync contact of lightning. Flashes can be applied to the second shutter curtain ( with the internal flash and certain flash units ).

The firmware of the camera is maintained by Pentax.
