Well, my order is in now, but all three ran out of stock likely long before I placed it. I think B&H received five or six; the others probably about the same numbers.
I'm in no particular hurry, thankfully. I have enough to do while I wait ... and my current equipment is still working well. I really can't take best advantage of the E-5 until Adobe updates Lightroom and Camera Raw to handle its raw files anyway.
(Makes me wish again that more manufacturers would give us the option to capture both their native raw files and DNG files in the camera ... Pentax has been doing that since the K10D, it made it possible to process K10D files long before Adobe or anyone else had updated their software for the native .PEF files.)
But I digress. I'm looking forward to this camera now. Once it gets here, it will become my primary tool for quite a while.
