sensor. This employs an optical


low-pass  lter to suppress moiré


and aliasing artefacts, and by


pairing it with a DIGIC X image


processor, users get an ISO range


of 100-51,200 (expandable to


50-102,400).


High among its impressive stills

capabilities is its ability to shoot


45MP  les at a staggering 20fps


with full AE and AF tracking using


its silent electronic shutter.


Switch over to the mechanical


shutter and it’ll rattle out a burst


at 12fps, which is faster than its


Sony Alpha 7R IV and Nikon Z 7


rivals. It has a deep buffer to


handle the high volumes of data,


and records to a CFexpress card.


A second UHS-II compatible SD


card slot is also added for


backup purposes, or separating


still images and video.


A breakthrough on the EOS R5

is the introduction of in-body


image stabilisation (IBIS).
Canon’s claim of it being the
‘worlds best stabilisation’ is a
bold one, but it holds true to its
claim by being effective up to 8
stops when paired with certain
RF-mount lenses. Even some
lenses with no optical
stabilisation can bene t from up
to 8 stops of stabilisation. One
example is the RF 28-70mm
f/2L. In instances where the EOS
R5 is used with Canon lenses
that feature optical image
stabilisation (IS), the lens
corrects yaw and pitch while the
body compensates for roll around
the lens axis along with vertical
and lateral movements.
The autofocus system focuses
down to -6EV in low light, while
also allowing teleconverters to be
used with relatively small-
aperture lenses, and compact
super-telephoto lenses like the

RF 600mm f/11 IS STM and RF
800mm f/11 IS STM. Focus
acquisition occurs as fast as
0.05sec, there are 5,940
selectable AF points covering
98% of the image area, and
Canon’s subject recognition and
deep-learning AI technology is
inherited from the EOS-1D X Mark
III. In the case of the latter, it is
programmed to recognise and
track cats, dogs and birds. Face
and eye detection is improved to
recognise faces more accurately.
Along with the usual prede ned
Servo AF case sensitivity
settings, the EOS R5 introduces
a new Case A (Auto) setting that’s
intelligent enough to select one
of the four subject-speci c AF
cases in response to changes in
subject movement.
The EOS R5’s video spec is
remarkable on paper. It’s the  rst
mirrorless camera capable of

recording DCI 8K (8192x4320
pixel) or UHD 8K (7680x4320)
raw video internally using the full
width of the sensor at up to
30fps for up to 20 minutes. The
high data throughput demands
that a CFexpress card is used
when shooting in 8K (unless you
use IPB compression) and there
is the option to grab 35.4MP
JPEG still images at the same
time. There’s a plethora of bit
depth and compression options
in the video menu, including
broadcast quality 4:2:2 10-bit
output and Canon Log to produce
footage with extra-wide dynamic
range and generous exposure
latitude for easy colour grading in
post production. 4K video
meanwhile is available in DCI
(4096x2160) and UHD
(3840x2160) resolutions at up to
120p for smooth slow-
motion capture. At frame

The sensor’s impressive dynamic
range allowed the sky and
foreground to be balanced from a
single raw file. Canon EOS R5, Canon RF
