The K- 70 sports an APS-C-sized 24-megapixel
sensor with a maximum ISO of 102,400.
It employs a new Hybrid AF system that uses
both image-plane phase-matching and contrast-detection autofocus technology to keep pace
with moving subjects. As a result, the K- 70 is
actually the company’s first DSLR to support
continuous AF during video recording.
There are 11 focus points with nine cross-type points in the center of the frame. You can
focus in low light down to - 3 EV.
While the K- 70 isn’t a flagship, it has many
of the signature features found on higher-
end Pentax models. Among them is the
Pixel Shift Resolution System that uses the
camera’s shifting sensor to create an ultra-
high resolution, low noise image from
a compilation of multiple exposures,
each with the sensor moved by a tiny
increment. For the K- 70, Pixel Shift
has been updated with a motion
correction function that detects
minute motion in an object in the
scene to prevent blur. When not
providing for sharper images,
There’s also an AA Filter
Simulator that effectively
eliminates moiré without the
need for an anti-aliasing filter.
The simulator is available in
three strengths (including off )
and you can bracket all three for
There’s also Wi-Fi but no GPS. However,
if you spring for an optional GPS unit, you
can enable another signature Pentax feature—
ASTRO TRACER—to take tack-sharp long
exposures of the night sky.
The K- 70 continues the Pentax tradition of
highly ergonomic, button-endowed bodies.
It’s comfortable to shoot with, though we do
wish the front dial was a tad larger.
There are three user-programmable slots on
the mode dial and a pair of customizable function
buttons on the body to map to the camera setting
of your choice. The 3-inch display swings
out from the camera body and is great when
angling for those tough-to-reach shots.
The K- 70 delivers a pleasing JPEG image and
its 14-bit DNG RAW file offers a fair degree of
latitude when it comes to purging noise in post-processing software. We found noise to be well
contained in JPEGs through ISO 3200. There’s
no quibbling with the color reproduction, either.
As we’ve noted in our reviews of other
Pentax models, the Pixel Shift Resolution
mode does indeed coax out more fine details,
slightly better color and a tad less noise than
a standard capture. Be warned, it will devour
your memory card—while the camera’s
typical RAW file weighs in at around 30MB,
our Pixel Shift files were 140MB. Even with
the motion-correction function enabled, this
mode is strictly for photographing completely
stationary objects with the camera locked
down on a tripod.

The K- 70 sits just above the K-S2 in the Pentax pantheon of entry-level DSLRs. While it doesn’t
share the steeper price tag of its higher-end siblings, it’s still generously apportioned with a
number of novel Pentax features found on those pricier bodies.
