The PENTAX K-3 Mark III features a high-performance viewfinder with a high-refraction glass pentaprism to provide approximately 1.05-times magnification (with an FA 50mm F1.4 lens set at infinity). Despite the compact, lightweight APS-C-format SLR body, it delivers a truthful, wide-view image equal to that of a full-frame SLR, and helps you to become more fully immersed in the photo-shooting process.
This viewfinder also provides an almost 10-percent increase in brightness, thanks to the improved reflectance of the pentaprism, while also assuring a nearly 100-percent field of view. By incorporating a distortion-compensating optical element and optimizing the lens coatings, it provides natural, true-to-life image rendition with high-magnification observations.
Since the viewfinder eyepiece is designed to protrude from the LCD viewfinder display screen — to prevent your nose from contacting the camera body — you can look into the viewfinder more naturally and comfortably.
The eyepiece also features an eye sensor, which turns the monitor off the moment you bring your eye up to the eyepiece ring. This prevents the status screen’s illumination from affecting visibility during shooting, while allowing you to capture images more comfortably.
The PENTAX K-3 Mark III features a transparent LCD viewfinder display that provides a broader range of data in the viewfinder window. Because you can adjust the camera’s settings without taking your eye away from the viewfinder, you can concentrate more fully on the subject.
The camera also allows you to program the desired combination of display data, such as grid pattern and AF focus point, making it easier to swiftly change settings for a specific scene or subject.
The PENTAX K-3 Mark III features a leaf switch, a mechanism previously used in the PENTAX 645Z and PENTAX K-1. Compared to the tactile switch more commonly used in compact SLR cameras, the leaf switch provides a lighter, smoother shutter action and minimizes the camera shake caused by the shutter-release action. It also helps you by providing effortless hold-down of the shutter-release button during continuous shooting.
The time lag between the shutter release and an image capture has also been reduced, compared to the PENTAX K-3 II, while the camera’s mirror- and shutter-driving mechanisms have also been upgraded. By reducing unwanted mechanical actions such as mirror bounce, it provides crisp, pleasant shutter-release action. You can feel the smooth action and speedy response every time you press the shutter-release button.
For comfortable shooting and easy carrying, the PENTAX K-3 Mark III’s grip and control-button layout have been optimized to accommodate different hand sizes and finger lengths. Perfected after producing a series of mock-ups and conducting repeated verifications, they let you to concentrate completely on your photo shooting.
The conventional Hyper Operation system allows you to instantly shift the AE mode to Tv (Shutter-priority) or Av (Aperture-priority) when the camera’s exposure mode is set to P (Program). The PENTAX K-3 Mark III's new-generation Hyper Operation system provides more flexible exposure-mode control, by adding a new Advanced mode* to the conventional Standard mode.
By turning the front/rear electronic dial, you can instantly switch the AE mode from P to Tv or Av.
Also, by providing single-action switching between Tv and Av, this mode assures intuitive operation in capturing an image, by emphasizing the subject’s motion, or the depth of field of the scene.
This new mode not only provides speedy switching between Tv and Av, but also features instant shift to the TAv (Shutter/Aperture-priority) mode simply by changing the shutter-speed and aperture settings.
Also, by changing the ISO sensitivity setting, you can flawlessly shift to the M (Manual) mode, harmonizing the easy photo-shooting of Programmed AE operation with the flexible exposure control of manual operation.
The PENTAX-original Smart Function provides easy, single-action selection of menu items and functions.
Featuring a new Smart Function button, the PENTAX K-3 Mark III now lets you preprogram a maximum of five functions from 22 options, and displays a list of the selected functions in the viewfinder window, so you can select the desired function without removing your eye from the viewfinder. It even lets you select and program the desired values for each function, allowing you to more precisely customize this function to meet your preferences.
Featuring 10 customizable control buttons positioned around its body, the PENTAX K-3 Mark III allows you to assign the desired function from 29 options to each of them. Thanks to this customized camera operation, you are guaranteed to have the same comfort and ease of operation as with your current camera.
The PENTAX K-3 Mark III lets you customize the functions of the front/rear electronic dials, Green button and Smart Function dial (when the Smart Function is assigned to one of the electronic dials). You can also set the functions separately based on the shooting format (still-image or video) or exposure mode.
You can even set the ISO button shift to the ISO Auto mode, or use the exposure compensation button to function as a reset button. Simply by assigning the desired function to each of these buttons, you can easily and freely customize camera operations.
The PENTAX K-3 Mark III features a large 3.2-inch LCD monitor with touch-screen control. By combining intuitive touch-screen control with the four-way controller and the front/rear electronic dials, it provides a new, user-friendly system that enhances speedy camera operation.
On the top panel, the PENTAX K-3 Mark III features a second LCD panel, which provides easy confirmation of the functions and settings selected for the Smart Function, in addition to providing basic data such as exposure and drive-mode settings.
You must be aware that each of your classic and cherished lenses creates its own distinctive ambience in captured images. That’s why the PENTAX K-3 Mark III has been designed to accommodate classic lenses. The camera not only saves the aperture value as Exif data when you set a desired aperture using the electronic dial, but also lets you measure the light and capture images at closed-down aperture. It even accommodates the TAv mode.*
It also provides more segmented setting of the lens’s focal length in SR (Shake Reduction) shooting.
When required to manually input the focal length of a lens for SR operation, the PENTAX K-3 Mark III allows you to select a desired length from the history log, in addition to the preprogrammed ones, to minimize the time and trouble required for manual setting.
