But then this is where the 5D3 comes in.

Got a shocked telling off from a friend of mine when I deleted an image I'd taken on his brand new 7D. He told me it was possible to damage the processor by deleting images from the memory card 'in camera'. ONLY delete the images off the card when the card is being read on a computer, he told me. Never heard THAT before, and can't quite believe it. Is this true? If so, why? - and surely Canon wouldn't provide a 'delete' button!
Here are some miscellaneous pictures I took from a recent vacation.
DO NOT USE SIMPLY ELECTRONICS
Best place for price in the UK that I know is www.procamerashop.co.uk
Then it's HDEW cameras.
For anything other than cameras and lenses then Dale Photographic or Warehouse Express.
Has anyone else used procamerashop? Their prices look a little on the cheap side across the board, which always sets off alarm bells for me. I don't mean to slander them if they are genuine, but £899 for a 7D body? Most places sell them second hand for more than that!
Edit: I've looked at hdew cameras as well and they seem to be the same prices. Neither of these sites appear on Camera Price Buster; I don't know if this comparison site takes commission (which might explain this), but it seems a bit strange...
I don't think that people should make too much of the "ISO 12800 maximum without expansion" on the D4 versus the "ISO 51200 without expansion" on the 1D X; I think this is just a difference between the two companies' nomenculture. The term 'native ISO' is misleadingly used by many people; each sensor only has one native ISO (its base ISO); in Canon's case this is ISO 100 and in Nikon's ISO 200. Every other ISO is achieved by either on-chip amplification, or by under/over-exposure with post capture software signal amplification. I had always thought that the switch over point was where the ISO expansion (boost) settings kicked in, but recent forum posts by others have led me to believe that I was wrong in this assumption. It seems that where this transition occurs is somewhat of an opaque subject that is not revealed by the manufacturers. Thus, one canot tell from the quoted ISO range specifications what one can expect in terms of signal to noise ratio for each sensor. It seems that each company has its own standards for what it considers acceptable signal to noise for its cameras "normal" ISO range. The only way to determine the sensors' signal to noise performance will be to test the actual sensor post-release (i.e. we'll have to wait for DXO Marks analysis). Of course, some are suggesting that the camera manufacturers are starting to 'cook' their RAW files by subjecting them to a certain amount of post-capture noise reduction during the initial on-chip stages of image read out.
So I was a little discouraged about just buying the 35mm three weeks ago and hearing that the new 35mm ii will be this up and coming CES.
