excellent image quality - good enough for most people, most of the time
generally sharper edge-to-edge than full frame cameras
quiet, non-intrusive, small, light, well built with good ergonomics for most people
nearly every button is customisable and the 2×2 switch effectively allows you to allocate an alternative mode setting to each button rapidly
very nice dual dials to control the main settings
small, light, relatively inexpensive high quality lenses (eg. the primes and f/2.8 zooms)
weatherproof and freezeproof - you can be confident in pouring water onto it!
fastest S-AF of any camera for slow moving or stationary subjects
unique ability to accurately AF on a subject's closest eye almost anywhere in the frame
usable C-AF tracking
better low light performance than most other cameras thanks to having the best
image stabiliser of any camera
reduced need for tripod - you can hand hold down to 1-1.3secs for those wide angle running water shots!
no need for large, heavy stabilising rigs for run and gun style video - the
image stabiliser is that good!
-
ability to use 0.7x Metabones Turbo adapter with full frame lenses giving additional 1 stop aperture and shallower
depth of field (DOF)
-
unique Live BULB and timed BULB modes
fast x-sync of 1/320th sec
shutter 60sec to 1/8000th sec
burst rate to 10fps but only 1st AF lock at that rate, otherwise 6.5fps with AF and
image stabiliser
tiltable touch screen mode offers additional shooting options for AF and shutter release
full control with smartphones via WiFi could enable interesting remote control uses
new Toshiba EVF is excellent and offers enough advantages that most will not miss their optical viewfinder too much.
nice intervalometer mode up to 999 frames (don't forget to set camera to 16:9 beforehand if you want to create 720p in-camera movies with the jpegs)
jpeg gives great colours and the sharpening is now dependent upon lens used and only applied to in-focus regions leaving your lovely bokeh untouched
no need to lockup mirror to reduce camera shake as with dSLRs in high magnification work - also has option to use electronic 1st curtain shutter instead of mechanical shutter for speeds 1/320th sec or slower to further reduce image blur from the shutter (set AntiShock to 0secs).
can use same TTL off-camera flash cords as Canon
