hi I'm Ben pilling Technical Marketing
Manager for digital imaging at Sony
Europe and this is the alpha 7 our mark
3
it's the latest camera in our alpha
liner it features a 42 point 4 megapixel
full-frame Exmor R sensor and an evolved
BIOS X processor it can shoot up to 10
frames per second with full auto focus
and auto exposure either with the silent
shutter or the mechanical shutter it has
a fast hybrid autofocus system featuring
399 phase detection points covering
around about 68 cents in the image
sensor and 425 contrast detection points
and furthermore it has embody
stabilization offering you up to five
and a half stops of effective correction
and outstanding 4k movie that's with
full pixel read out without pixel
binning all these features are added to
with great operability which is
inherited partly from the alpha 9 to
deliver a great addition to our lineup
the alpha 7 our mark 3 features a
full-frame sensor it's an export our
structure which means it's back
illuminated giving great low-light
results it also has 40 2.4 megapixels so
outstanding detail and resolution but
this is aided by an involved BIOS X
processor this is the same processor
that we use in the Alpha 9 and we also
use the front end LSI from the alpha 9
as well not only is the processor 1.8
times quicker than its predecessor but
along with the new front end LSI it
helps deliver even better image quality
coming out of the sensor that means we
get even better low-light quality and
dynamic range than before offering up to
around about 15 stops of dynamic range
the alpha7 are mark three can choose up
to 10 frames per second that's either
with the newly developed low vibration
mechanical shutter or in silent shooting
the camera uses a fast hybrid autofocus
system this combines phase detection
autofocus with contrast detection
autofocus there are 399 phase detection
autofocus points built into the image
sensor and these are very good at auto
focusing quickly and tracking moving
subjects it also has four hundred and
twenty five contrast detection autofocus
points covering a wide area of the frame
as well contrast detection is very
accurate these two types of focus can
combine to give great results with the
alpha 7 our mark 3 add-on to that we
have the eye autofocus function which
has been very popular our cameras but
compared to the predecessor it tracks
about twice as well with the alpha 7 our
mark 3 furthermore for low-light
autofocus the camera can now focus down
to e V minus 3 the alpha 7 our mark 3
also has embody image stabilization this
means that the sensor itself is
suspended and can be moved to counteract
shake of the camera this works in five
different axes pitch your X Y and roll
and it can be effective up to five and a
half stops so that means you can use a
shutter speed five and a half times
slower than you would normally expect to
be able to achieve without getting
camera shake
the Alpha Ceph now mark 3 also features
4k movie recording it can do this with
the full frame or in aps-c or super 35
millimeter mode if you're shooting in
the aps-c or so-called super 35
millimeter mode it does full pixel read
out without pixel binning that means it
takes information from every single
pixel that's using and combines them
together to make that 4k image it's
effectively over sampling on the sensor
to give really detailed 4k output in
addition to that it also has hybrid log
camera
hlg this means that you can record
footage in camera that can be output on
4k screen instantaneously in 4k HDR
rather than having to post process and
color grade your footage it's give a HDR
result
furthermore the office of an ARMA 3
features and fans video features you
might be familiar with from our cameras
so it has picture profiles s log 2 and s
log 3 as well as so motion option on
there as well
the r7r marker has great operability so
we now get a touch screen on the back
and this can also be used even while
you're using the viewfinder there are
multiple options to deactivate certain
parts of the screen if you're using the
viewfinder so you don't accidentally
touch somebody that means touch whether
you're a left eye or a righty shooter
and you can also customize that touch
screen to be the relative or absolute so
you can either be dragging the point or
pressing exactly on the screen where you
want that to be while you're using the
viewfinder speaking of the viewfinder
it's the same viewfinder as the alpha 9
so that's three point six nine million
dots and an OLED unit with a not point
seven eight times magnification so it's
big IFS bright and gives great color
accuracy on there as well the build
quality again is very similar in size to
the alpha 9 so we get the same dial on
the back a bit more sturdy than the
predecessor and many customizable
buttons and on to this we also have a
dual card slot so slot 1 is also UHS 2
compatible and works extremely well with
the sony SFG series
furthermore we have the zseries battery
which we had in the Alfa 9 this gives
others up to around about 650 shots with
the LCD screen by super standards and
you might find in actual usage you get
even more than that there are lots of
customizable options for the r7 armed r3
so not only custom buttons but you can
also refine the auto focus settings on
the camera in a similar way to the alpha
9 the terminals on the office of NARM
actually also differ slightly from its
predecessor we get to USB terminals a
micro terminal an USB C terminal this
means that you could use one for power
while using the other one with our
remotes or alternatively we also have a
new software imaging edge it features
imaging edge remote viewer and edit with
the remote software you can tether with
live view we also have of course micro
HDMI terminal and a headphone socket and
a microphone socket as well but what's
new in comparison to the predecessor is
a sync socket for studio flash and again
that couldn't potentially be used up to
10 frames per second for really creative
results so that's the r7 our mark three
outstanding resolution dynamic range up
to 10 frames per second and a great
autofocus system if you'd like to see
