Pentax announces the KF, a slightly-tweaked version of its K-70 APS-C DSLR

The KF is effectively unchanged from its 24MP K-70 predecessor, aside from a slightly higher-resolution articulating rear display, a few grams shed and a collection of new Custom Image presets.

| Main Featues of the PENTAX KF |​

1. Super-high-resolution with approximately 24.24 effective megapixels, even at ISO
   102400 A state-of-the-art CMOS image sensor with approximately 24.24 effective megapixels and high-speed 14-bit image data readout, combined with an AA-filter-free optical design, enables the PENTAX KF to deliver super-high-resolution images. The camera couples a high- performance accelerator unit with the high-speed PRIME MII imaging engine, effectively minimizing noise at all sensitivity levels and capturing richly gradated, fine-detailed images even at its top sensitivity of ISO 102400.
2. Dustproof, weather-resistant body perfect for rugged outdoor photography
   The PENTAX KF is a dependable performer even in such demanding settings as in the rain or at locations prone to dust and freezing temperatures. Its compact, easy-to-carry body features dustproof, weather-resistant construction with 100 seals throughout the body and outstanding cold-proof performance at temperatures down to 14°F (-10°C). To make it easy to ensure a firm hold on the camera body with a gloved hand, the grip, control buttons on the back panel and mode dials have all been designed and contoured for optimum operability, ideal for active outdoor shooting — such as when mountain climbing or hiking or capturing sporting events. The brightness level of the PENTAX KF’s outdoor-friendly LCD monitor can be quickly adjusted to the lighting level of a shooting location. The camera also features a red-lighted monitor display function, which facilitates viewing in dark locations for astrophotography.
3. Clear-view optical viewfinder
   Within its compact body, the PENTAX KF incorporates a glass prism finder featuring the same optics and coatings as those used in higher-level models. With its approximately 100% field of view and nearly 0.95-times magnification, the PENTAX KF’s viewfinder provides a large, clear view of the subject for quick, easy confirmation of focusing and framing.
4. Vari-angle LCD monitor for easy viewing from all angles
   The PENTAX KF’s vari-angle LCD monitor allows the monitor to be positioned at the desired angle, making it easier to compose images in a wide variety of situations: high-angle shooting using outstretched arms, low-angle shots taken from ground level or astrophotography with the camera pointed upwards toward a star-filled sky. It also features unique, air-gapless construction, in which the air space between the high-definition LCD panel (with approximately 1,037,000 dots) and the protective cover has been filled with a special resin material to effectively reduce the reflection and dispersion of light for improved visibility during outdoor shooting.
5. PENTAX-original shake-reduction system with Pixel Shift Resolution System
   

   (1) In-body SR mechanism

   Using the built-in PENTAX-original SR (Shake Reduction) mechanism, the PENTAX KF effectively minimizes camera shake and delivers sharp, blur-free images, even in challenging, shake-prone conditions such as when using a telephoto lens, shooting low-light scenes with ambient light only, or photographing sunset scenes. Using a high-accuracy gyro sensor, it provides a compensation effect of 4.5 shutter steps, similar to top-of-the-line PENTAX models.

   With a panning shot, the sensor mechanism automatically detects the direction of the camera’s movement and controls the SR unit to produce the best image possible.

   (2) Pixel Shift Resolution System with motion correction function

   The PENTAX KF features the Pixel Shift Resolution System,* which captures four images of the same scene by shifting the image sensor by a single pixel for each image, and then synthesizes them into a single, composite image. Compared to the conventional Bayer system, in which each pixel has only a single color data unit, this innovative system obtains all color data in each pixel to deliver super-high-resolution images with greater color accuracy and much finer details than those produced by conventional APS-C-size image sensors. This system even provides a motion correction function,** which automatically detects a moving object during continuous shooting and minimizes negative effects during the synthesizing process in order to accommodate a wider range of scenes and subjects.

   (3) Innovative AA filter simulator to minimize moiré

   By applying microscopic vibrations to the image sensor unit at the sub-pixel level during image exposure, the PENTAX KF's AA (anti-aliasing) filter simulator*** provides the same level of moiré reduction as an optical AA filter. Unlike an optical AA filter, which always creates the identical result, this innovative simulator lets the user switch the AA filter effect on and off, as well as to adjust the level of the effect. This means that the ideal effect can be set for a particular scene or subject based on the current photographic conditions.

   (4) Additional special shooting functions

   Since the PENTAX KF’s image sensor unit is designed to tilt in all directions, it provides a host of additional, special shooting functions, including ASTROTRACER, which simplifies advanced astronomical photography in combination with the optional O-GPS2 GPS Unit; and Auto Horizon Correction and Extra Sharpness functions.

6. Hybrid AF system for high-speed AF operation during Live View shooting
   The PENTAX KF employs the Hybrid AF system during Live View autofocus operation. By positioning a contrast-detection AF sensor with superior focusing accuracy and a phase- matching AF sensor on the image sensor’s surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint AF focusing on the subject.
7. High-precision autofocus system with the SAFOX X module
   The PENTAX KF features the high-precision SAFOX X AF sensor module, which assures responsive, dependable autofocus operation. With its 11 sensors including nine cross-type sensors in the middle, this AF module assures pinpoint focus on the subject at a minimum brightness level as low as -3 EV. It also assures outstanding AF tracking performance with moving subjects, enabled by advanced features such as the Select-area Expansion function, which automatically refocuses on a moving subject after it moves away from the initial point, with the help of the neighboring points; and an AF Hold function that maintains the initial in-focus point even when the module loses sight of the subject.
8. An array of image processing functions for diversified photographic expression
   The PENTAX KF provides the PENTAX-developed Custom Image function, which lets the user process an image with the desired finishing touch to express the creative intention, or to suit the particular scene. This function provides 14 Custom Image modes, including: SATOBI, which reproduces the colors to resemble those of pictures in the 60s and 70s, with cyan- tinged blues, subdued yellows and faded reds; Bleach Bypass, which recreates the distinctive, high-contrast look of movie film; and Cross Processing, which adds fantastic, unusual colors to captured images. In combination with PENTAX Limited-series lenses, which are popular for their distinctive image renditions, the PENTAX KF also provides special-edition Custom Image modes KYUSHU and KATEN.
9. A host of interval shooting functions
   The PENTAX KF provides a host of advanced interval shooting functions, including: 4K- resolution Interval Movie, which allows recording a series of still images at a fixed interval and then linking them together into a single 4K-resolution movie file; Star Stream Movie, which enables recording the traces of stars or illuminations on a 4K-resolution movie file; and Interval Composite, which synthesizes a composite image with a choice of three synthesis modes (average, additive and comparative).
10. Wireless LAN connection to support smartphone operation
    The PENTAX KF provides a host of wireless LAN (Wi-Fi) functions to support operations using smartphones and tablet computers. By installing the dedicated Image Sync application on a smartphone or tablet, the user can remotely check the Live View image, capture still images, and adjust such camera settings as aperture, shutter speed and ISO sensitivity to the desired level through the mobile device. It is even possible to download captured images onto a mobile device for easy uploading onto social networking service websites.
11. Other features
    • 77-segment multi-pattern metering system for high-precision light metering
    • DR (Dust Removal) mechanism to remove dust from the surface of the CMOS image
      sensor
    • High-speed shutter unit with a top speed of 1/6000 second, and high-speed continuous shooting function at a top speed of approximately six images per second ・ Self-timer function, compatible with the continuous shooting function

Από ότι είδα είναι ίδια ουσιαστικά με την παλιά Κ70 χωρίς καμία αλλαγή, δεν ξέρω τι νόημα είχε μια τέτοια ανακοίνωση, βέβαια με την αλλαγή ονόματος και την φρέσκια ανακοίνωση ίσως κάποιοι ψαρώνουν και την πάρουν θεωρώντας ότι είναι αναβάθμιση από τις παλιές Pentax.

Υ.Γ. Από την άλλη μπράβο στην Pentax που είναι η μόνη εταιρία που επιμένει ακόμα σε Dslr…για ποσό ακόμα βέβαια άγνωστο….

αν ειχε αλλη μοντουρα φακων ισως να ειχε νοημα αυτο που κανει

με την ιδκη της μοντουρα τωρα μονον οι παλαιοι κατοχοι pentax μπορει να την προτιμησουν ως επιλογη και αναβαθμιση εξοπλισμου που εχουν ηδη φακους.

Δεν ξερω που θα παει αυτη η ιστορια προφανως ειναι σχεδον στο ιδιο μονοπατι με την Olympus απλα με αλλο τροπο.

Ενταξει δεν είναι στο ίδιο επίπεδο με την Olympus….η Pentax δεν έχει καταφέρει καν να βγάλει mirrorless ή να δώσει AF σε βίντεο με χρήση ibis….ούτε 4Κ δεν έχει η συγκεκριμένη..οι φακοί αν δεις οι περισσότεροι δουλεύουν με το γνωστό κατσαβίδακι….είναι εκτός τόπου και χρόνου η Pentax….αυτά που βγάζει θυμίζουν εποχές 2010…μόνο για ρομαντικούς ή για όσους έχουν φακούς Pentax και δεν θέλουν να τους δώσουν….
