Some interesting thoughts on the EM5 over at the onlinephotographer and Biofos.com

My first question to Olympus UK when I was given the pre-announcement images and specification was 'Can this new camera operate 4/3rds lenses any quicker than existing m4/3 machines (does it have a PDAF sensor on the chip?) Unfortunately the answer came back "No AF improvement on 4/3 lenses I am afraid".
I was disappointed with this news; it seems that Olympus' promise of 'One beautiful system' is not here yet, and I suspect may never arrive as the engineers have already dropped a pretty big hint that this ambition might be more difficult to achieve than they first thought. So where does this leave the 4/3rds faithful? To me it looks like Olympus may have to continue producing a top-spec 4/3 camera such as an E-6 or E-7 if they are to abide by their previous promise that there will always be a body on which 4/3rds lenses can be used to full advantage. So, in that sense, the OM-D, as well as offering a top-spec m4/3 machine (weatherproof), also guarantees the continuation of the 4/3rds line, albeit with one camera only!"
The AF performance of the OMD and the FT lenses is further confirmed at the onlinephotographer
1st look of the EM-5 over at the onlinephotographger:
"I asked about AF performance with the standard 4/3 E-system lenses, and Olympus said there was nothing special to highlight on that front, implying it was roughly the same as the E-P3."

I'm not surprised by his statement re: AF of 4/3 lenses.... will have to be patient and wait for the E7 to show.
Another interesting tid-bit:
"Some other random notes: Olympus says the E-M5's ability to follow-focus moving subjects is "dramatically" improved, able to track a subject while maintaining a 4.2 frames-per-second burst rate. If that turns out to be reliably true across a modestly wide range of real-world (as opposed to test lab) conditions, and the percentage of sharp pictures is reasonably high, that would be a significant breakthrough for contrast-detect autofocus. I'm skeptical for the time being but hoping to be pleasantly surprised."
The EM-5's looking like a pretty sweet cam, esp in black - might possibly get one esp for street shooting but only with one or two primes,the Pana 20mm f1.7 and the 45 F1.8 would be more than enough. I've been surprised with the reviews of the 12-50Zd's and how poor its optical quality, so primes would be my setup. However, that new Fuji ProX range finder looks mighty pretty as well!
I'm looking forward to seeing what Oly does with the E7 .. we know its in the works, so fingers crossed we get to see something later on this year!
