112 DIGITAL CAMERA^ DECEMBER 2019 http://www.digitalcameraworld.comony doesn’t want
the Alpha 7R IV to be
thought of solely in
terms of resolution, but
a 61MP sensor is bound
to grab the headlines. It beats its full-
frame rivals by some margin, and
re-establishes Sony as a front-runner
in a full-frame mirrorless camera
market that’s become very busy.
But the A7R IV is not just about
resolution. It has a very rounded
balance of overall image quality and
versatility, combining its ultra-high-
resolution with 10fps continuous
shooting capability and a buffer that
can sustain this for up to 7 seconds.Sony’s epic hybrid AF technology
takes another step forward too,
with 567 phase-detection AF points
spread across 74% of the image
area and 325 contrast AF points.
It now offers Real-Time AF tracking
in its movie mode, too.
And just to drive home the
resolution point once more, the Alpha
7R IV has a Pixel Shift Multi Shooting
mode than can combine four images
for full-colour data for each pixel
(avoiding the demosaicing
interpolation process cameras
normally use) or 16 images with
sub-pixel movements to create
240-megapixel photographs.Specifications

A larger front grip
makes the A7R IV a
little easier to handle,
but the body still lacks
height for a good ‘grip’.2
Inside is an NP-FZ100
lithium-ion cell which
gives a battery life of
530 (viewfinder) or 670
shots (rear screen).3
The Sony FE lens
mount is now very
well-supported both
with Sony optics and
