Pentax 645z Press Release:
Ricoh Imaging Corporation: The (President Akabane Noboru), employs a large CMOS image sensor with new, as well as ultra-high-resolution images of approximately 51.4 million effective pixels, and a comfortable operation corresponding to professional use will be released interchangeable lens medium-format digital SLR camera equipped with a high reliability the “PENTAX 645Z”.
This product, we have developed based on was launched in 2010 the “PENTAX 645D”. I realize an image with excellent three-dimensional depiction in the ultra-high-definition and renew the image processing engine and image sensor to pursue the improvement of reliability and higher image quality in addition to dust and water structure with a reputation, of approximately 51.4 million effective pixels have. In addition, the Live View function continuous shooting performance of about 3 frames / second highest, high-resolution tilting LCD monitor, the AF system of the latest, exposure control with high accuracy, shutter unit or the like with improved durability, substantially of the key features By providing an improvement in operating response and enhanced Na, also has mobility that is required in the field of professional. In addition, it also includes such linkage function of the smart phone with wireless communication and full HD movie recording, and finish the model to expand greatly, the freedom and the possibility of new video expression.
1. High-definition Image of approximately 51.4 million effective pixels
To the imaging device, I am proud of adopted area size of about 1.7 times the size 35 Mirifuru-size, the new CMOS image sensor of 43.8mm × 32.8mm. Image processing engine “PRIME III” to match, was enhanced image processing capabilities of the high image quality and noise processing, by combining a low-pass filter-less design, approximately 51.4 million effective pixels having excellent stereo imaging performance and high resolution I am an ultra-high-definition image of.
In addition, by reducing drastically the noise of high ISO speed, ultra-high-sensitivity photography of the highest ISO sensitivity 204800 is also possible, and has enabled beyond the common sense of the medium-format conventional format, a new shooting representation You.
2. Fast response to meet the demands of professional
(RAW shooting, JPEG: up to 30 frames is L · ★ ★ ★ when) to 10 frames at about 3 frames / second highest and enables continuous shooting. Also, in addition UHS-I compatible with a high-speed writing to the SD card when using the corresponding speed and quick-view display to (SDR104 standard), PC Transfer is compatible with USB3.0 standard. By implementing a fast response on the heels of 35 mm, meet the requirements of professional use would like to use in a variety of shooting scene the 645 system, and has realized the comfortable operation.
3. AF system with high accuracy
The module of the phase difference for AF, the latest corresponding to the 27-point AF “SAFOX (support Fox) 11 (Eleven)” (25 points center cross-type) is adopted. Three points of the top and bottom center is compatible with luminous flux of F2.8 to be effective in focusing severe large-diameter lens in use. In addition, AF luminance range-3EV also covers a wide range (ISO100, room temperature) and ~ +18 EV, focusing on the naked eye has been to facilitate the focus of difficult against a dark subject. Further, by adopting the CMOS image sensor capable of high-speed read and has the live view function again. It is possible to magnify the AF or by contrast method in the live view screen, the screen, to perform a more precise focus.
4. 3.2-inch tilting up and down, large LCD monitor of about 1.037 million dot
3.2-In addition to the wide viewing angle, I adopt a tilt type move up and down the monitor, to facilitate high-angle shooting and low-angle, It is equipped with high-definition large-screen LCD monitor about 1.037 million dots (3:2 aspect ratio) have. Further, to effectively suppress the reflection of light by the air gap-less structure is adopted glass durable, eliminating the air layer between the liquid crystal surface, the protective cover is AR to reduce glare ( By performing also Anti-Reflection) coating, you greatly increase the visibility of the outdoors.
Full HD movie recording of 5.1920 × 1080:60 i
Full HD movie recording 1920 × 1080:60 i/30P employing the H.264 recording format is possible. It is possible only by the large sensor, depth of field is shallow, to shoot smoothly this video blurred effectively background.
In addition to the built-in stereo microphone, also equipped with stereo microphone terminal of external input, you can also adjust the audio recording level. In addition, interval video 4K overwhelming high-resolution image at (3840 × 2160 pixels) size: also includes (Motion JPEG AVI) shooting function, I can enjoy a wide range of video expression.
6. Body robust and reliable
Strongly to temperature changes to the chassis, and has adopted the aluminum die-casting of high operating accuracy, robustness, a magnesium alloy lightweight frame to the back of the LCD monitor and the exterior of the camera body. In addition, I adopt a tempered glass scratch-resistant on the LCD cover on the back and the upper surface, and enhance strength. In addition, as it is provided with a shutter mechanism which cleared the operation test of 100,000 times greatly increase dust-proof and drip-proof structure which gave the ceiling to 76 places, cold performance of up to 10 ℃ minus, durability, including but not limited to outdoor people I am more reliable in the scene shooting Na.
7. The exposure control with high accuracy due to “Pentax real-time scene analysis system”
Improvements exposure algorithm employed for RGB metering sensor about 8.6 million pixels, it is possible to significantly improve the exposure accuracy, and by linking to the white balance and auto-focus information from the photometric sensor and to improve the performance of each ” I have adopted the Pentax real-time scene analysis system “. I have to allow for exposure control in line with the intended shooting more, that to properly determine the subject or scene by photometric sensor. In addition, the separation accuracy of the background and the main subject, dimming accuracy of flash photography is also improving.
8. Optical viewfinder Large, easy-to-view
Was employed (trapezoidal) prism glass Torapizoido different in shape pentaprism general, it has an optical viewfinder a wide field of view of about 98% while reducing the size of the body size of the camera. In addition, there is a reputation for ease of focus and brightness to the focusing screen, eyestrain has been adopted by a few “Natural-Bright-Matte” all shooting for a long time.
9. Cooperation with the smartphone can Note 1
FLUCARD FOR PENTAX 16GB “O-FC1”: by (optional sale) use, live view display and the release of the smartphone, view pictures taken, download, etc., can be.
It supports smartphones iOS6 later, equipped with OS of Android ™ 4.2 or later Note: 1.
10. To remove dust adhering to the sensor “DRII (Dust Removal II)” mechanism
It is equipped with a mechanism to “DRII” prevent the reflection of dirt out of the photographic image. It is possible by making ultrasonic vibration by a piezoelectric element to UV · IR cut filter portion of the image sensor front, that even if the dust adheres event, can be effectively removed. In addition, the function “Dust Alert” can be confirmed also in preparation for the shooting before the adhesion state of the waste, and enhance the sense of security when you are shooting and interchangeable lenses in dusty places, such as outdoors, an important work.
11. Operation functions of the feelings that corresponds to the professional use
-Can be easy to see the live view output and image confirmation of the PC monitor, such as bird’s-eye view taken from directly above or photo duplicating, when shooting upside down the camera and is equipped with a rotating display function and 180 degree rotation record 180 degrees.
(2 types) are available make it easier to check the position of the subject in the screen, a small square grid of display during live view. Grid lines can be selected from two types of black-and-white.
· We have established a lock button that you want to temporarily disable the dial buttons and can prevent accidental configuration changes.
