The K-1’s optical viewfinder provides a nearly 100-percent field of view and a 0.7-times magnification to deliver a sharp, crisp view of the subject and a large, well-defined image field, both of which are the benefits of the 35mm full-frame SLR camera. This viewfinder also provides a clear view of the image field free of aberrations, even at the edges. Its Natural-Bright-Matte III focusing screen* makes it easy to identify the in-focus point, even during manual-focus operation
At-a-glance confirmation of the camera’s operational status
The K-1’s transparent LCD viewfinder display allows you to select desired data, such as a grid display, and monitor it in the viewfinder. It comes in handy when correcting the camera’s tilt using the digital level or rearranging the image composition using a grid pattern, without taking the eye off the subject.
The Digital Level displays the K-1’s horizontal and vertical tilt with two bar scales. Compared with the conventional type that utilizes an exposure bar scale, it not only makes it easier to identify the camera’s tilt, but also allows you to check the tilt and exposure status simultaneously. As the result, it greatly improves the camera’s operability during viewfinder shooting.
Transparent data to be displayed in the viewfinder (grid pattern, Digital Level, AF frame and spot-metering frame) can be turned on and off independently to accommodate varying shooting conditions and preferred shooting styles.
From ultra-wide angle to super telephoto, an entire selection of high-performance DA-series lenses can be used on the K-1 without any modification. They deliver exceptional image quality, despite their compact, lightweight design.

When a DA★-, DA Limited- or DA-series lens is mounted on the K-1, its Crop mode automatically switches an image area to the APS-C size covering the middle section of the image field, while displaying the cropping frame in the viewfinder. It not only assures high-resolution images with approximately 15.36 effective megapixels, but also provides an efficient AF sensor coverage of the image area for more flexible image composition during autofocus operation. When you select the FF (Full Frame) setting of the Crop mode, you can even capture a 35mm full-frame image with a DA-series lens.*

The following DA-series lenses cover the 35mm full-frame image area. When the Crop mode is set to FF (Full Frame), the K-1’s lens aberration compensation function is extended to cover certain aberrations, such as diffraction, in the 35mm full-frame image area.※

The K-1 provides a wide range of customization settings to optimize the ease and comfort of camera operations. These settings have been designed to expand the functions of the USER Mode and the Fx (function) buttons, improve accessibility to desired functions on the control panel, and prevent accidental operational errors.
Five different combinations of the most frequently used functions can be assigned to this mode to handle specific subjects or creative intentions.
This panel displays a list of the functions and their status on the LCD panel, while allowing you to change the contents and/or order of listed functions to suit your shooting style.
In order to prevent accidental setting changes, the K-1 provides a lock button to temporarily inactivate control buttons and dials. It offers you a choice of two lock functions: Type 1 to prevent unintended exposure setting changes; and Type 2 to prevent operational setting changes.

The K-1 inherits PENTAX’s development concept of a compact body and ease of handling in the field. PENTAX has completely restructured the mechanical unit containing the shutter charge and mirror driving mechanisms, while repositioning the finder unit to keep the camera’s height to a minimum. PENTAX’s advanced high-density packaging technology has succeeded in creating a compact, maneuverable body for the new K-1.

In order to accommodate the 35mm full-frame image sensor and cover the light flux of the large viewfinder with a nearly 100-percent field of view, it was necessary to increase the size of the main mirror and mirror box. To minimize the size of the mirror box, PENTAX has developed a new mechanism that retracts the main mirror as it swings upwards.
