Sony a7R full frame mirrorless camera
introduction
announced Oct 2013
-
36mp not 24mp
has no AA filter
has no PDAF, only CDAF points
is NOT capable of electronic first curtain mode
4fps not 5fps burst
flash sync only 1/160th sec not 1/250th sec, which is a bit poor
magnesium alloy body not composite
really needs to be used on a tripod to make the most of the high resolution sensor
who is it for?
specs
36mp sensor with no anti-alias filter
no PDAF
Bionz X processor
improved sharpening algorithms
diffraction reduction software for small apertures
context-sensitive, 'area-specific noise reduction'
focus peaking
panorama sweep mode
4fps burst
shutter 30sec - 1/8000th sec but loud and no electronic silent mode and does NOT have electronic first curtain mode, which would have allowed for a quieter shutter, and reduced the potential for 'shutter shock' vibration
flash sync 1/160th sec
no built-in flash but multi-interface flash shoe
Multi-Interface Shoe allows you to connect a latest model Sony flash, an external mic, video lamp, or XLR adapter
exp. compensation ±5 EV
ISO 100-25,600
3“ tilting 1.23m dot LCD but not touch sensitive
XGA EVF
1080 60/24p HD video with uncompressed HDMI out
no timelapse recording
USB 2.0
weather sealed, composite body
WiFi with NFC
465g
127 x 94 x 48 mm (5 x 3.7 x 1.89″)
NB. does not ship with a proper battery charger, instead it comes with a Micro USB cable and the AC-UUD11 AC Battery Charging Adapter (a USB to AC converter)
$2299 body only
optional vertical grip & 2nd battery holder ~$300
compared with Nikon D800E
same sensor
the Nikon allows fast phase detect AF and has a wide range of Nikon AF-S lenses
the Sony allows fast phase detect AF only with the extra $350 adapter and the Sony Alpha lenses
the Sony allows fast CDAF and Eye-AF with CDAF-compatible lenses (very few currently)
the Sony allows manual focus with almost ANY 35mm full frame lens ever made
the Sony offers 1080 HD video at 60p not just 30p, and potential for better C-AF
the Sony is far smaller, has WiFi/NFC and is $700 cheaper
reviews
-
-
difficult to shoot with
shutter vibration issues giving double images at certain shutter speeds
slow AF, not well suited to street photography
best suited to still life shots on a tripod with the best quality lenses matched to the sensor
-
-
video quality is poor - poor codec, poor resolution, lots of moire
poor ergonomics and mechanical shutter
