I humbly come here seeking advice. I placed this thread here as it will touch many cameras and/or systems so bear with me.
Long ago (and thanks to this place) I came to the realization that there is no one camera that does it all (yet). To wit, I am currently sporting two camera systems: A Sony A99 for my stage and studio work and a Fuji X-E1 for my travel and walkabout needs.
I do want to make the move to MFD for my studio stuff, but MFD will never cut it for live stage performances. The A99 takes lovely shots but lacks the 3rd party support Canon and Nikon have. I could sell the A99 kit and go with a Nikon D800 for the dance/studio work keeping the Fuji for travel.
However, Oly's upcoming E-M1 paired with the 4/3 35-100 f/2 lens would be more than adequate for my dance needs (assuming the PDAF speed is as good as they claim), plus the OM-D line is small enough for travel needs using the Oly 12-40 f/2.8. If (and it's a big if) that camera performs as claimed, I could conceivably use that to replace Fuji & A99 for travel and dance needs and can then concentrate on committing the perfect bank robbery to fund the MFD gear I want. Just kidding. But some nice used gear financed by someone more trusting than the bank would be great.
That, long windedly, is my mental dilemma. Any thoughts on the matter would be appreciated.
