Hello - I'm new here in the forum.... but been visiting the site for years
Anyway.... I've got to agree with the comments from 'neuroanatomist' .....basically Canon are ultimately a business in it to make profit pure & simple, ....we might of all complained about how bad the 5D & 5D2 focussing was
(even after reading reviews)... but hey, they still sold a shed load!
I recently got to spend about 1 hour playing with the new 1DX the other day

.....and chatting with the guy from Canon, who was closely guarding it.
As always (obviously)... he wasn't giving away any new possible info about future cameras (particularly my questions about the possible 5D3 !) ....but one thing he did mention, was that Canon certainly weren't going to make the same mistake they did with cannibalising sales of the 1Ds3.... when they released the 5D2.
The 1DX will be the 'Ferrari' of their line-up.....
(his words) .......he also mentioned..... that Canon IS listening and evaluating all the feedback!
I suppose it's nothing we didn't already know..... but it just re-confirms the comments from 'neuroanatomist'
That the 5D3 .....will have to be substantially different this time for Canon not to not have a repeat performance, so unfortunately IMO - the autofocus will probably remain the same if not only marginally better.
I own a 5D & 5D2.... and just as much as everyone else, I would love to have autofocus that nailed it dead on every time, in low light (EV - 2), without the need to use an ST-E2 as a focus assist! ...and that also works on moving subjects - (not running sports like subjects! ...just walking towards camera in low contrast like situations would be fine). Obviously it's not all that doom & gloom, as the images it produces are amazing..... you just learn to work with it's shortcomings, and occasionally get disappointed when it misses a moment because of it.
For me & my business (commercial & weddings)... personally the 1DX is
probably looking like it will be the perfect camera! ...18mp is ideal in terms of file size, I pretty much only shoot on SRAW1 anyway, unless the client really needs large files. The ISO improvement looks amazing
(from what I could see) hopefully the dynamic range is too (though I'll pass judgement on both of those on the final release product & reviews) ....and the speed of the autofocus was just sublime & so natural in your hand, especially coming from the 5D2 center point re-compose method! Selecting your focus point is just ridiculously fast!!
So what's the issue....?? .....for me
(and probably lots of people) - it's just the price! ...I realise it's never going to be in the ball park of 5D2 prices but if it was £1000 less.... I'd be pre-ordering now!
But this just makes me want to work harder and save more! ...I reckon it will come down slightly after a few months, and start to level off (as does any new camera at launch) but it's starting price
(which apparently according to the - Canon Rep) ...is still liable to change before March, as economic and competition factors still play a major part in deeming what it's final price will be at launch.
5D3 - whatever it will be! ......IMO - I just can't see it being the camera for me now..... and especially after handling and knowing what the 1DX can do.... and then thinking logically about how Canon have played their cards in the past.
So come on Nikon - where's your new D4... at a reasonable price?
