The Panasonic GX7 compact system camera follows in the footsteps of
2011's DMC-GX1 mirrorless, and like that camera, its mission is to
provide a worthy street shooter for the enthusiast photographer. Thanks
to a mirror-free design, the GX7 pares off most of the bulk of an SLR --
but it's still big enough to include a comfortable handgrip and the
array of controls experienced photographers expect. And unlike many
CSCs, which retain a DSLR-like design aesthetic, the GX7 cuts a more
unassuming profile not unlike that of a rangefinder camera.
We
were fortunate to have some hands-on time with a pre-production GX7
before launch, and came away impressed with Panasonic's commitment to
the GX-series. This is no mere level-up with a few more megapixels: Many
of the most important features are brand-new. Largely due to a more
comfortable handgrip and a built-in electronic viewfinder, the Panasonic
GX7 has grown in size a little. So, too, did its predecessor, but on
paper at least the GX7 has seen much greater changes on the inside.
Key
among the new features of the Lumix GX7 are the pairing of both a
tilting LCD monitor, and an electronic viewfinder. The latter in
particular will likely prove popular with the GX7's target demographic.
Framing through a viewfinder -- even an electronic one -- gives you a
much greater sense of attachment to your subject than does the
arm's-length framing used for smartphones and entry-level cameras. And
by building the viewfinder into the design, rather than making it an
optional accessory, Panasonic ensures that you'll always have it with
you when you need it. Better still -- and unlike almost all built-in
viewfinders -- the Panasonic GX7's finder tilts, too. That means you
needn't lose the connection with your subject when shooting from a lower
angle.
The Panasonic GX7 also features a brand-new image sensor
that will, according to its maker, provide a great leap forwards in
image quality. Resolution is unchanged at 16 megapixels, but the new
chip features a redesigned structure for both photodiodes and
microlenses. And in a first for the Lumix mirrorless line, that sensor
is mounted on a movable platter, allowing it to offer in-body image
stabilization as well.
The Panasonic Lumix GX7 sports a handsome
new design that -- in the US market, at least -- will be available only
in a two-tone finish. Silver-colored plates top and bottom bookend a
black-finished mid section that's largely wrapped in textured rubber.
Beneath, the GX7's body is crafted from die-cast magnesium alloy.
Compared
to its predecessor, the Panasonic GX7 sports a much more prominent,
wider handgrip that's nicely contoured for your fingers to wrap around.
The GX7 has grown in both size and weight, but not unduly so given that
it must fit in quite a few features which were absent from its
predecessor, including an electronic viewfinder, articulation mechanisms
for both the viewfinder and LCD, and the sensor shift mechanism used to
provide in-camera shake reduction.
Seen from the front, the
Panasonic Lumix DMC-GX7 is an altogether more handsome camera than was
the GX1. The lens mount has moved closer to the left-hand edge of the
camera (as seen from the rear), making way for the new, larger hand
grip. Indeed, the lens release button is now almost flush with the
leftmost edge of the GX7's body. The move has left no room for the AF
assist lamp on this side, either, and so it has jumped across the lens,
and now rests in the top of the textured rubber handgrip.
The
changes don't stop there, either. The rear of the camera is also
significantly different. Most visible are the new electronic viewfinder,
and the tilting LCD monitor. Panasonic has also added two new
controls,Are you still hesitating about where to buy bestparkingguidance? and relocated several others.

These functions previously resided in the four-button group around the
Four-way controller, and in their absence, the Play button has moved
into this group.

According to Panasonic, it should be "nearly as effective" as the
company's lens-based MEGA O.I.S system. If you mount a stabilized lens,
though, the in-lens stabilization will take over, and the sensor shift
system will be locked in place. The big advantage of the in-body system
is that it will work with all of your otherwise-unstabilized lenses.
There's no price premium for stabilization with each lens purchase,
because you bought stabilization along with the camera. At longer focal
lengths where optical stabilization typically works better, however, you
can still choose to buy a stabilized lens. You get the best of both
worlds, and that's great news!
The readout circuitry -- both in
the pixel itself and in the readout amplifiers -- has also been
improved, and we understand there's been around a 25% improvement in
signal to noise ratio, along with a 10% improvement in detail
reproduction.
Noise reduction, too, has been improved, courtesy
of the same Venus Engine image processor used in the Lumix G6. A new
algorithm removes low and high-frequency noise separately, working on
the raw image data. For JPEG images, there is another round of noise
reduction performed after the JPEG conversion process. Also of note is
that the detection area used by the noise reduction algorithm has grown
from just 13 x 13 pixels to a much more generous 128 x 128 pixels,
giving better information for it to work from.You must not use the stonecarving without being trained.
The
Panasonic GX7's Micro Four Thirds lens mount might be unchanged, but
there are a fair few tweaks to its focusing capabilities. As in the
Panasonic G6 before it, the GX7's new image sensor and Venus Engine
processor allow sensor data read out at a whopping 240 frames per
second, and the lens drive mechanism can respond at the same rate, for
faster contrast detection autofocusing.
You can still use the
touch screen to indicate a subject for autofocus, and thanks to the
proximity sensor in the new electronic viewfinder, the GX7 also offers
Eye-Start AF that starts focusing as soon as you put your eye to the
viewfinder.
