I just hope Canon haven't made some bad eggs. I find it strange that after all the hype over their 1DX that was announced weeks ago, there isn't any high iso sample images. In fact the samples they have posted aren't exactly wow I need one of them camera's. Especially with the release of the D4 and D800 who's sample images are far better even though they too haven't shown high iso ones on the offical site, but shots from the D800 at iso 6400 are out there on blogs. So if the 1DX really lives up to the hype " performance redifined " then what are they afraid of? Also im concerned as to what they are going to do with new 5D, as now there is specualtion of it having an old AF from the 7D or 1DIV, not thats really bad but this is 3year old tech. Nikon have had awesome AF for years now in the D700 ( I know cos I've used one a lot ) and know they have improved it further in the D800. My only fear is that the new Canons need to match the Nikons AF at the very least, as I'm not interested in 14fps and iso 51200 if the shots are OOF then it's all irrelavant. My friend who is a fellow wedding shooter has a D800 on order an I can't wait to give it a try. I dont want to switch because of the money invested in L glass etc but at the end of the day I need a camera I can rely on on the job, I'm sick of taking shots and having that doubt as to whether they are going to be tack sharp. It frustrates me as when I've used a borrowed D700 on on a few of my weddings it was like taking candy from a baby, shooting at 2.8 the dam thing never missed. Come on Canon stop pussy footing about and release some awesome kit, there's thousands of us sat here waiting to spend vast amounts of cash, don't let it go to Nikon!!!
