Expanded Pentax K-3 Mark III Digital SLR Camera Body Key Features:

High-Resolution, Accurate & Versatile

You might think that in a world that's moving towards exclusively mirrorless systems, what can an APS-C DSLR camera offer me? Well, the K-3 Mark III features an array of technology that enables the capture of beautiful and dramatic images and videos, and its compact and lightweight design makes it perfect for travel photographers and videographers. The K-3 III is equipped with a high-resolution 25.7-megapixel APS-C imaging CMOS sensor and Prime V Image engine & accelerator unit which not only can capture stunning images but offers beautifully crisp 4K and Full HD video capture, and the camera allows for up to 25 minutes or 4GB of constant recording.

To complement these capture features, the K-3 Mark III is fitted with Pentax's advanced and intelligent 5-axis sensor-shift shake reduction "SR II" IBIS that offers a stabilisation compensation effect of 5.5 steps. This ultimately results in significantly reduced camera shake in stills and smoother video capture. In addition to this, the camera is afforded a newly designed AF system that offers fast and accurate phase-matching autofocus that is able to accurately track subjects even with the K-3 Mark III's extremely fast continuous shooting speeds.

AA Filter Simulator

Brought to us in the original K-3 camera body and seen throughout this series is one of the world's first AA filter simulation systems. This simulation technology recreates the effects of an optical AA filter by applying microscopic vibrations to the CMOS imaging sensor during exposure, resulting in significantly reduces false colours and moiré.

This intelligent system gives you three settings that result in different levels of the effect such as finding the best balance between image resolution and moiré, prioritisation of moiré compensation and finally a prioritisation of image resolution. The result of this advanced system is that when using the K-3 Mark III you effectively reap the benefits of two completely different cameras - a high-resolution AA-filter-free camera, and a highly colour accurate and moiré assured AA-filter camera.

The Optical Viewfinder

This newly designed optical viewfinder (OVF) sees an improvement over the K-3 II body by providing an approximately 1.05x angle of view (previously approx. 0.95) which is equal to that of a full-frame model. Pentax needed to increase the magnification, which can be achieved by sacrificing eye relief, but this would result in an inferior viewfinder. So instead, Pentax designed a high-refraction glass pentaprism that increased the viewfinder magnification which compromising the eye relief.

The improvements don't stop there. In addition to the newly developed magnification, Pentax has updated the viewfinder display system by optimising the viewfinder optics and prism with specially designed coatings that significantly reduce colour tinting, reflections and distortions within the system. By adding these optical corrections, the K-3 III provides a huge improvement to both viewfinder image quality and user experience.

Shutter Upgrades

Adopting the three-leaf switch mechanism that's featured in Pentax 645Z and K-1 series, Pentax moved away from the tactile switch in the shutter-release mechanism used on the K-3 II that was used to reduce the size of the camera body. The decision to change this was for the simple reason that the K-3 III needed to have a lighter and smoother shutter action.

As well as this, it was important to reduce the anxiety of unexpected or accidental shutter releases. The three-leaf switch provides just the right amount of pressure and depth without needed to apply excessive force, which is particularly useful as it helps stabilise the camera at the moment the shutter is released and makes for effortless continuous shooting without fear of shutter failures.

Ergonomics & Ease-of-Use

The goal of the K-3 III was the develop a camera that allows you to effectively concentrate on your image-taking without working about the rest of the camera, allowing you to truly communicate directly with your subject and scene. For this reason, the K-3 III features some differences in shape and ergonomics, including the optimisation of the grip shape and control layout to provide optimum comfort and shooting and ease-of-use with all hand sizes and finger lengths.

Pentax value viewfinder shooting and because of this, the focus of the build was on the viewfinder image and the cameras image-tracking performance. Because of this, the K-3 III features a high-quality fixed-type touch LCD panel. During development, decisions were made to prioritise compactness and sturdiness of the K-3 III body and without the sophisticated and often bulky articulated LCD mechanisms seen on other models, the K-3 III has an overall reduced body-size and internal structure.
