Pentax K-01

Released February, 2012
  • 16.1 MP
  • APS-C 23.7 x 15.7 mm CMOS
  • 3" LCD
The difference between the K-01's JPEG and Raw output is clear here, and as we'd expect, shooting in Raw mode and applying sharpening post-capture gives better resolution than you'll achieve by relying on the camera's default JPEG processing.

Reviews Word on the street for the Pentax K-01


6.9
By spending 30 seconds in Photoshop, your ISO 12800 photos can now be printed even larger, and ISO 25600 suddenly becomes a lot more useful.

7.0
We didn't like the price quite so much - £679.99 / $899.95 with a lens is quite a lot to pay for a compact system camera, and comparable to the excellent Pentax K-5 with the same kit zoom lens.

7.0
ISO performance is another area where the K-01’s CMOS sensor performs very well.

6.0
The screen is bright and clear and provides wide viewing angles, but the glossy acrylic cover can hamper visibility when viewing the screen from an angle in bright conditions.

7.4
If you've got a stable of Pentax lenses - especially good ones that can properly resolve to the sensor - and feel like doing some creative shooting, especially with manual focus, then the K-01 is a great choice.

What People Are Saying Give it to me straight

Lens

The other two lenses are standard Pentax kit lenses, neither of which will win any awards.
by DPReview (May, 2012)
Speeds vary depending on the lens you're using, with the 40 mm kit lens being one of the better ones.
by DPReview (May, 2012)
I switched to a friend's F2.8, 50 - 135 mm DA* lens, and it performed extremely well, as it should for its $1600 price tag.
by DPReview (May, 2012)

Focus

The K-01 is definitely not the performance champ when it comes to autofocus speeds.
by DPReview (May, 2012)
Unfortunately, the truth of the matter is that the K-01’s autofocus performance is just not that good.
by Nathan-Ingraham (Jul, 2012)
It’s a decent, if unspectacular rate — and if you’re using autofocus, expect your results to drop quite a bit from there.
by Nathan-Ingraham (Jul, 2012)

Sensor

It has a 16 Megapixel CMOS sensor, K-mount lens support with built-in (sensor-based) image stabilization, lots of manual controls, a boatload of scene modes and special effects, an HDR function, and 1080p video recording.
by DPReview (May, 2012)
The K-01 includes Pentax's TAv (Shutter Speed and Aperture Priority) mode, in which the aperture and shutter speed are user set, but ISO is automatically adjusted to match the metered value.
by DPReview (Mar, 2012)
The K-01 is able to record JPEG (three quality levels), Raw or simultaneous JPEG and Raw images.
by TrustedReviews (Jun, 2012)

Image quality

A combination of careful noise reduction and sharpening in post processing can still yield good results though.
by TechRadar (May, 2012)
If the K-01 can successfully combine best-in-class image quality with a dedicated live view camera and many of the K-5's photographic features, then it'll really be the worth some attention.
by DPReview (Mar, 2012)
Dynamic range is good, with plenty of detail being retained in shadow and highlight areas.
by TechRadar (May, 2012)

Video

Overall, while it’s nice to have video included (and I appreciate the many resolution and frame rate combos available to users), the quality is ultimately not at the level where you’d want to do anything more than shoot a quick clip here and there for your personal enjoyment.
by Nathan-Ingraham (Jul, 2012)
The K-01 also offers the best video mode of any Pentax mirrorless or DSLR camera to date, with the inclusion of Full 1080p HD recording at a variety of frame rates, handy one-touch recording button, auto and manual focusing, the ability to change the aperture or shutter speed during recording, a socket for an external mic and an HDMI port for easy connection to your HDTV.
by Photography Blog (Apr, 2012)
At the end of the day, video is just not very good on the K-01 — I recommend looking elsewhere if you're a dedicated video shooter.
