The Pentax K-1 II is a 36MP full-frame DSLR (image sensor size 24 x 36 mm). The K-1 II is an upgrade of the K-1 with a few additions, one of which is innovative (pixel shift available in hand-held shooting).

The K-1 II continues the trend of Pentax flag ship models of being a photographer's camera with a user friendly layout, superb handling in a relatively compact form factor, and a feature set targeting the serious photographer.

New features compared to the K-1:

  • Pixel shift super resolution is now available also when shooting hand-held
  • Sensitivity up to ISO 819,200 (for an extra two stops)
  • Hardware accelerator unit which preprocesses the image before it hits the Prime IV engine
  • Improved image quality at high ISO thanks to the accelerator unit (image resolution, color reproduction, and noise reduction)
  • Improved autofocus performance through updates to the AF firmware

Other key features common with the K-1:

  • Full-frame CMOS sensor
  • 36.4 megapixels w/ 15-megapixel crop mode
  • 3:2 as well as 1:1 aspect ratio
  • No AA filter
  • AA filter simulator
  • Shutter rated for 300,000 actuations
  • Electronic shutter as an option in live view shooting mode
  • 5-axis sensor-shift stabilization
  • Viewfinder with LCD overlay
  • 6.5 FPS in crop mode, 4.4 FPS in full frame mode with up to 100 JPEG buffer
  • Rear monitor tilts and pivots
  • Rear monitor night view mode
  • LED illumination of lens mount, buttons, and card slot
  • Dust & weather sealed
  • Built-in GPS and Wi-Fi
  • USB tethering support as well as tethering via Wi-Fi

The viewfinder has an LCD overlay with a customizable grid, crop area indicator, and dual-axis electronic level. The grid can be enabled or disabled via the menu, as can most of the other features of the overlay.  A dedicated light illuminates this overlay on demand. The viewfinder has 100% coverage and a 0.7x magnification which makes it a tad bigger than the viewfinders of the APS-C format cameras.

The pixel shift capability has been improved over the K-3II in that it will attempt to correct artifacts stemming from moving objects. Furthermore, with the K-1 II pixel shift can be used when shooting hand-held.

The shake reduction is rated good for 5 shutter steps compensation.

The camera has no anti-alias filter in front of the sensor. Should moiré be an issue the K-1 II includes the unique Pentax feature of an AA filter simulator that works by vibrating the sensor ever so slightly during exposure thereby reducing or eliminating moiré. The simulator has three settings (off - weak filter - strong filter). An AA simulator bracketing mode is available.

The body is made from magnesium alloy surrounding an inner steel chassis.

The K-1 II will be available in a body-only kit and in a kit with the high quality, budget friendly HD D FA 28-105mm F3.5-5.6 zoom lens. For shooters wanting fast F2.8 zoom lenses, the range from 15mm to 200mm is covered by the HD D FA 15-30mm F2.8 ultra-wide zoom, the HD D FA 24-70mm F2.8, and the HD D FA* 70-200mm F2.8. For additional reach the HD D FA 150-450mm F4.5-5.6 is available. All lenses mentioned cover the full frame format.

All current and legacy K-mount lenses are compatible with the K-1 II. M42 screw mount, 645 and 6x7 lenses can be used with the appropriate adapters. With DA K-mount lenses the camera will shoot in a 15 MP crop mode with the active area outlined in the view finder. The crop mode can be overridden which is useful in connection with those DA lenses, that perform well on full frame. Among these are the DA* 200mm, DA* 300mm, and DA 560mm lenses. The K-1 even offers lens correction for these three lenses when they are used in FF mode.

Until we get our hands on a K-1 II we point you to the in-depth review of the original K-1 here.

Review Date: September 20, 2018 I can recommend the Pentax K-1 II: Yes | Price: $1,896.00 | Rating: 10 

Pros: Very fast AF, lovely solid feel, packs a mighty punch in a small package.
Cons: Faster burst speed would be nice.

This machine is solidly built. It feels even more robust than the K-5.
These dials and buttons feel solid, but with a lovely smooth motion. Like something well engineered with fine tolerances.
It's smaller than I thought. It really is not much bigger than the K-5. I think I'll need to get a battery grip for it, as I did for the K-5.
The shutter sounds glorious. In the K-5 it's noisier and more of a jarring sound. This just sounds smooth and controlled.
Man oh man, this thing focusses fast.
The viewfinder is sublime. Large, very clear, super easy to read the displays.
Under the Mode Dial, there's this neat little "lock-unlock" slide. Turns out, you can slide that to one side and it removes the need to push the centre button to rotate the Mode Dial. The Mode Dial still has a nice smooth click function from one setting to the next, but you need not depress the centre button when the 'lock' is unlocked.

As some of you may be aware, I won this camera in the raffle.

A huge thank you to Adam!

Review Date: June 18, 2018 I can recommend the Pentax K-1 II: Yes | Price: $1,700.00 | Rating: 10 

Pros: Good handling, cheap for a FF, great features, video adequate.
Cons: Too early to tell, focussing speed not comparable to Canon but much better than K3.
Years Owned: .1    Ergonomics: 10    Build Quality: 10    User Interface: 9    Autofocus: 8    Features: 10    Value: 10    Image Quality: 10    Noise: 9    New or Used: New   

I had considered waiting for the K3 III however due the bargain price from the distributor in Oz I bit the bullet. At first I thought oh-oh can I afford new FF lenses but when I checked my current lenses a few were rated as FF. I have now had a practice with my suitable lenses:
70 -200 Sigma f2.8 (upgraded mount and firmware - free), Voigtlander 58mm Nokton and 40mm Ultron, Tamron 90mm Macro . I have since purchased the 18-105 kit lens and I am mightily impressed with K1 MkII, particularly with the low-light capabilities providing a few more stops to 6400iso and allowing slower lenses to be used. The increased ability to crop makes up for the gaps in the range of lenses. I am no great shakes as a photographer but this camera is fun to use and complements my KP (another bargain at $700) nicely. Or maybe vice versa. It is well balanced without a grip. As far as the comparison to the K1 goes, I wouldn't know and don't care. Not everyone can afford or wants every iteration of Pentax cameras.

Review Date: April 21, 2018 I can recommend the Pentax K-1 II: Yes | Price: $2,500.00 | Rating: 9 

Pros: Full frame, Light sensitivity, handling, intuitive operating, weatherproof. Love the tilting display, rugged like a tank, but most importantly: makes great pictures.
Cons: Layout feels a little clunky at first. Power hog!

What can one say after 8 days? I will adjust this review as time passes. For now I am thrilled with picture quality, though for me, full frame with regards to vignetting on various lenses is a developing skill set. Tons of features, and higher light sensitivity. The accelerator in the processing makes a difference. Of course, don't expect to ever take useful pictures at 800,000 ISO. However, with that being said, IQ good enough for good portraits at 1600 ISO seems possible. For now, very happy. Some pictures are on my Flickr gallery or THIS GROUP.
