no built-in EVF - this will not suit many people like me who MUST use an EVF as I can't view the rear screen without reading glasses, plus I don't like taking photos with the camera held away from my eye - it is just bad practice for image quality (camera shake). Of course you can buy the lovely VF-4 EVF but this adds bulk and uses up the hotshoe.
not weatherproof - well you can't have everything!
no add-on improved grip for larger lenses - this may make it a bit more difficult to use for long periods with the heavier lenses such as the
Olympus m.ZD 75mm f/1.8 lens
re-located exposure mode dial may cause confusion issues for those who also use the E-M5
movie mode not class leading by any means - if you want the best quality movies in a camera not too much bigger than this, you need the
Panasonic GH-3
focus peaking mode does not work in movie mode and does seem to slow the frame refresh rate down
intervalometer limit of 99 images means you can only shoot 4secs of 24fps movie
timelapse movie mode only shoots at 1280×720
Live View remote control only works in iAuto stills mode - no movie mode or other exposure modes as yet, and unlike on the
Panasonic GH-3 it locks the camera's controls during use
LCD screen is not fully articulating and thus cannot be used for self portraits, but then you can use the Live View remote feature with your smartphone to address this
LCD screen goes below the camera when tilted downwards - this means, unlike the E-M5's screen, it cannot be tilted down on flat surfaces or on tripods - unlikely to be an issue!
tripod mount is offset to lens axis which may annoy some
9fps burst mode same as on E-M5: AF and AE set on 1st frame then subsequent frames are locked to that initial setting, no IS unless using OIS lenses.
buffer limit same as on E-M5: means max. of 19 jpegs or 15 RAW in 9fps burst mode
