I have had 3 Canon camera and have been happy with them over the year. 20d 40D and 5D Mk11
I have out grown two of them mind you I still use the 40D a lot though when it comes to macro it lets me down as its only 10mps so Its the twinlite all the time
Not the 5DMk11 is a great camera for everything, I bought it two years ago this Month but I am sorry to say I dont like the performance of the 24-105 L f/4 mm lens
I wish now I had not bought that lens and waited till I had enough money for the Canon 16-35mm f/2.8 L lens though going Overseas at the time I could not afford the extra.
The 5D Mk 11 has 21 mps and I dont have a problem with that camera I really like it.
If you bought that as its way cheaper than what I paid in 2010 and coupled with the 16-35mm lens for landscapes that would be a great twosome.
P.S. Just been looking at the price of the 5D Mk 11 and I am almost tempted to buy another one rather than wait for the 7D Mk 11 ? to come out
