Optical viewfinder with approx. 100% field of view, and approx. 1.05X magnification
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.
Operability that affects sensibility
Pleasant shutter action
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.
Ergonomic design for responsive camera operation
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.
New-generation Hyper Operation system
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.
More versatile Smart Function
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.
