Sony a7R full frame mirrorless camera

introduction

announced Oct 2013
similar to Sony a7 full frame mirrorless camera but:
- 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?
- landscape photographers using a tripod
- studio photographers using studio flash

36mp sensor with no anti-alias filter
- 25 CDAF points
  - Eye-AF, which locks the focus on the pupil of faces that are detected
  - Flexible Spot AF (with adjustable focus point sizes)
  - Zone AF
  - Lock-on AF C-AF
- excellent RAW dynamic range
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

$2299 body only
optional vertical grip & 2nd battery holder ~$300

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

dpreview.com's review
Ming Thein's review
- 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
- EVF not as good as on the Olympus OM-D E-M1 while the image stabiliser, weatherproofing and lens range is sorely missed
EOSHD review
- video quality is poor - poor codec, poor resolution, lots of moire
- poor ergonomics and mechanical shutter
