Originally posted by Aristophanes 1/8000 shutter is a rare need. Built in wi-fi is a rumour for the D610. Coming for all cameras anyway and seen in P&S's already. Nikon has a fleet of VR lenses and with that ISO advantage has less need.
If a camera is mostly about IQ and DOF control thenFF smacks the pants off the m4/3.
With the right lenses. This is kind of where the Oly falls down a bit as the FF Nikon range and aesthetic controls are well ahead of Olympus, even on price.
Thats just comparing the features of the two cameras. Sure you can get VR in heavy expensive lenses, but what about primes? sure you can get a dongle for wifi, but that is again, more cost.
For me, 1/8000 is very important, that was a major reason why I left the D800, and may go from EM5 to EM1. In the last year alone I have shot over 200 photos at 1/8000 shutter. even at iso 80. You need it if you like shoot at f1.4 to f2 in broad daylight without an ND, or in snowy conditions that refelect even more light.
This is why there are so many cameras to choose from, different needs for different people. If Pentax released a FF with 1/4000 and an APS-c with 1/8000 at the same time, I would buy the APS-C before the FF (in the end I would buy both, who am I kidding) but thats how important that feature is to me. Now, if the FF offered 1/4000 and a flash sync of 1/250 while the APSC was 1/8000 with the 1/160 flash sync... I have no idea which one I would buy first...
