All these improvements make the 5DM3 seem like an incredibly attractive camera, with enough there to merit upgrade consideration for 5DM2 pros who can justify the not-inconsiderable expense. If you're price-sensitive, the D800 obviously looks better, but you've got to be a real rez-head to consider the D800's pixel count a serious advantage and that presumes you're not committed to a system already.
Along with the 5DM3, Canon simultaneously announced some new accessories targeted at the same class of photographer.
  • Speedlite 600EX-RT ($629.99, March): This replaces the 580EXII at the top of Canon's flash offerings, finally incorporating wireless flash mastery. It supports radio or line-of-sight and five groups of flashes on 16 channels.
  • Speedlite Transmitter ST-E3-RT ($470, March): This is essentially the 600EX-RT without the flash.
  • Battery Grip BG-E11 ($490, April): Though the 5DM3 takes the same batteries as the 5DM2, the grip's been updated with a duplicated multicontroller.
  • Wireless Transmitter WFT-E7A ($849, April): This adds a lot of the wireless and wired Ethernet capabilities that come built-in to the 1D X, including time syncing, FTP, EOS Utility mode, WFT Server, and Media Server capabilities.
  • GPS GP-EP2 ($390, April): A hot-shoe-based GPS receiver that supports GPS logging.

First Review: Canon EF 600 f/4L IS II

By Craig BlairPhoto Credits: Ethan Meleg
I wanted to get a quick article out about the new $12,999 USD Canon EF 600 f/4L IS II super telephoto lens that the world has been waiting years for. When I got the call on June 1, 2012, that mine had arrived at Camera Canada, I was pretty excited. I wanted to make the 3 hour drive to pick it up, but I resisted and waited for it to arrive in the mail the following Monday. For a couple of days, the lens sat in our office and didn’t do much. I just didn’t have the time to get out with it.
EF 300 f/2.8L IS II, EF 400 f/2.8L IS II, EF 600 f/4L IS II, EF 800 f/5.6L IS (500 f/4L IS II still missing) What to do?I decided to give my good friend Ethan Meleg first crack at the lens. His mission, if he chose to accept it, was to take the lens out for one day and try to make some good photographs with it. He was up to the challenge and promised some bird photos worth looking at. I then bid adieu to my recently acquired 600 II.
As with any review here, there’…
