Main features of Pentax K5

1. High resolution, low noise and vivid image presentation.

K-5 adopts a newly developed CMOS photosensitive element, with a size of 23.7mm x 15.7mm and a wide range of sensitivity adjustment. Its image data reading speed is higher than all previous models. PRIME (Pentax Real Image Engine) II imaging engine with the same performance as that used by Pentax 645D medium format digital SLR camera is adopted. K-5 uses an image sensor with about 6.5438+0.628 million effective pixels, which can generate digital photos with ultra-high resolution and fine layers, and at the same time can suppress digital noise to a minimum. By default, the sensitivity of K-5 can be adjusted from ISO 100 to ISO 12800, and can be extended to ISO 80 to ISO 5 1200 through custom menu options to better meet the needs of different creations, such as taking full-aperture photos at low sensitivity or taking clear photos at low light.

2. High-speed continuous shooting function, continuous shooting can shoot about 7 shots a second.

K-5 can continuously take 30 photos at the highest speed of about 7 photos per second (JPEG storage format), which makes it easy for photographers to continuously shoot high-speed moving scenes, such as athletes, stage actors and wild animals.

3. High-response and high-precision autofocus system

K-5 adopts a new generation SAFOX IX+ wide area autofocus system, 1 1 focusing point (9 o'clock in the middle is cross focusing point). The system has undergone a brand-new design, and the accuracy of autofocus has been greatly improved because of the calculation of light source type during shooting. K-5 also offers a shutter release option-in autofocus. S (single focus) mode, you can choose focusing accuracy priority or shutter release priority, and in AF. C (Continuous Focus) mode, you can choose focus priority and continuous shooting speed priority, so that photographers can better set for different shooting needs. In addition, the K-5 also integrates a focus assist light, which helps to improve the focus accuracy in the dark.

4. Compact, sturdy and multifunctional fuselage

Although the body of the K-5 is compact, it is extremely durable. The shell is made of durable and light magnesium alloy, and the skeleton is made of high strength stainless steel alloy. Thanks to the sealing treatment on 77 parts of the whole body, K-5 also has a dustproof, waterproof and low-temperature resistant structure, which can ensure excellent reliability even in harsh conditions and low temperature environment of-10 C. K-5 also uses a very reliable shutter unit, providing a maximum shutter speed of 1/8000 seconds and a durable shutter release of 100000 times. Although K-5 has many functions, it still maintains a small and compact body design, thanks to Pentax's experience and expertise in product miniaturization accumulated in the era of film SLR cameras.

5. Bright and clear optical viewfinder with about 100% field of view.

K-5' s glass pentaprism viewfinder provides a visual field equivalent to about 100% and a magnification of about 0.92 times (using 50mm F 1.4 lens, focusing at infinity), which is more conducive to detecting focusing accuracy and picture composition. The improved new natural-bright-matte III focusing screen can help photographers focus manually. K-5' s bright and clear viewfinder ensures better outdoor shooting effect-especially when using telephoto lens-which enables photographers to focus on framing and shooting better.

6. Easy shooting in live view mode

Thanks to the new image sensor and more advanced algorithm, K-5' s contrast detection autofocus mode can ensure faster and more accurate focusing effect than previous products in Live View live view shooting mode. K-5 can also use three different grid lines, including the golden ratio, as an auxiliary reference for framing.

7. Pentax original SR anti-shake mechanism, while providing auxiliary shooting ability.

K-5 has the SR(Shake Reduction) mechanism developed by Pentax, which can effectively compensate the bad influence of jitter on the picture, and can realize the shutter speed compensation of 2.5 to 4 to ensure that the image is clear and unambiguous. This innovative mechanism is compatible with almost all Pentax interchangeable lenses, even though many lenses are designed for film cameras *. Because the new generation of anti-shake mechanism can move the photosensitive element freely to avoid the camera's inadvertent jitter, K-5 also provides automatic horizontal correction and fine angle correction (up/down, left/right, clockwise/counterclockwise, etc.). ) to help photographers better framing and composition.

* The lenses compatible with this mechanism include Pentax K-, KA-, KAF-, KAF2- and KAF3- bayonet and screw lenses (adapter rings are required); 645 and 67 system lenses (adapter ring required). Some functions of some lenses will not be available.

8. Full HD video recording (1920 x 1080 pixels, 25 frames per second)

K-5 provides video recording function, and can shoot beautiful video clips with the ratio of 16:9 full HDTV (1920 x 1080 pixels) at the rate of 25 frames per second. Extend the advantages of SLR photography to the field of high-quality short film shooting, such as highlighting the subject through the unique shallow depth of field of SLR cameras, or using special lenses to create unique visual effects. K-5 can also make movies more visual * * *, especially after using custom images and digital filters.

* * When the storage speed of the memory card used by K-5 is too low, video recording will be terminated.

* * * When using a specific processing effect, the number of shooting frames will change.

9. Innovative image processing functions bring unique image performance.

(1) Custom image function brings unique image processing effect.

K-5 has the function of customizing pictures, which allows users to easily choose the desired color style of pictures, thus better and more faithfully expressing the photographer's creative intention, or more strongly rendering the atmosphere when shooting. K-5 provides nine different styles of custom image modes, including the newly added silver-leaving development mode, which can shoot and create unique visual effects. On the basis of the original traditional definition and fine definition mode, K-5 also adds an ultra-fine definition mode, so that even tiny lines in the picture can be clearly presented and the picture resolution can be improved.

(2) Various special effects of digital filter.

K-5' s digital filter function allows users to process photos in a lot of creative ways, and can create special visual effects immediately without a computer. Users can not only choose from 18 different filters (including the latest sketch and tone separation filters), but also use multiple effects superimposed on a photo many times, thus creating endless effect combinations.

(3) Forward and reverse thrust shooting with three preset items

K-5 has a unique reverse mode, and the camera will automatically adjust the image elements of each photo, thus creating a unique color effect-just like the special effects brought by the reverse mode in the movie era. On the basis of the original "random" mode with unpredictable final effect, users have two more choices: the "default" mode has three preset color styles; Favorite mode allows users to enter their own tone parameters.

* * * * An unconventional film printing method can create a particularly charming picture color.

(4) HDR (high dynamic range) high dynamic range shooting function.

K-5 has HDR (High Dynamic Range) function, which can combine three photos with different exposures into a high dynamic photo with ultra-wide gray scale performance without any computer processing. Provide automatic, standard, enhanced (3 files optional) and other modes to meet different creative intentions. Thanks to the newly added automatic calibration function, users can even take HDR photos with the camera.
