I went into the Birmingham branch of WEX last Sunday - and some one (just a punter!) had one which I had a quick play with. I'd seen the hype before it was released and originally decided that it really was a lot of money and didn't want one. Well. The auto focus is simply incredible. Live view (Which on my 1Dx doesn't focus as such it has to drop the mirror up down and AF then return to live view) is so so quick - focus in the general area of a face and it finds the eye and locks on. Like a limpet. More the camera (or subject!) and it follows it. As quick as you like, It still remains locked on.
OVF (Optical view finder!) is similar though doesn't lock the eye (I don't think!) but does the face or what ever the point of focus is and stays with it.
The silent mode in live view is, well, lets be honest slow video - 20fps slow with full AF in that time.
It is so impressive that I've traded my old 1D3 in for it (Got next to bugger all for it
but did get a £500 bonus so made it slightly less painful!) And WEX are doing 2 years interest free credit (Parks I think are doing 1 year) so have gone down that route - might as well!
The bad news is that I have no idea when it arrives. The Canon shop is saying 2nd April - which I find hard to believe with the Photo show in the NEC happening mid March where they are going to surely have a few at least for sale? In truth I could cope with it being 2nd April - but not the 3rd unless it arrives early - because I go to Morocco for 2 weeks on an off road trip!
So, once again, I'm a lucky boy with a fabulous understanding wife!
