my wife is succesfully using a Pany GH2 with the kit lens 14-140mm ( due to Michael's recommendation) and she really loves the camera and the images it creates. But, and this is the issue, the AF is much too slow though she loves to shoot our dogs playing around in the backyard. Furthermore, she complaines a long delay between pressing the shutter and the the actual shoot is done, although shooting static objects in best light.
Because she would like to keep on using a small light camera, the idea is to switch to the Olympus OM-D M5.
Can anyone give me her / his experiences on this camera, especially in reagrd of the AF and the shutter-delay ?
if 14-140 is the only lens that you have/plan to have then it (14-140) is big enough that smaller EM5 body shall not make a big difference when 14-140 is mounted, you might actually want GH3 body to have a better grip and bigger/more controls... IBIS/OIS will not help w/ dogs playing as they are moving... better sensor will help (both EM5 and GH3 have Sony sensors as it turned out) - if you are using in camera JPGs then it is matter of your taste, if you are using raw converters then both cameras have identical raw quality... none of m43 cameras (neither EM5 nor GH3, both top models) have AF good enough for randomly moving objects tracking... if you plan to buy smaller lenses smaller EM5 body might be better... if you plan to mount manual focus lenses then IBIS might be helpful - but there is a shutter shock effect more pronounced w/ IBIS in EM5 (light body, floating sensor not being one mass w/ a body) at certain shutter speeds around 1/60 (IBIS can't counteract high freq. sensor movements when shutter induces those)... Olympus has antishock delay setup in firmware from 1/8 sec and longer to fix this (it allows those high freq movements to die off leaving only low freq hands tremor that IBIS was designed to counteract), but you were complaining about "long delay between pressing the shutter and the the actual shoot is done" - so you might not want a body w/ IBIS for such situations
