This really deserves a full length video review, but I am so far behind that this will have to suffice for now. This is the most important take home message:
Now that the Canon 6D
has pretty much replaced the Canon 5DII
as Canon's entry level Full Frame Camera, I am getting flooded with questions about how the 6D stacks up against it's bigger brother, the Canon 5Diii
The short answer on it is this: The Canon 6D is 1/2-1 full stop better in High ISO noise. Much of it depends on the subject matter you are shooting, but the higher the ISO goes, the better the 6D performs, but the tradeoff is sharpness. (6D starts to look softer, but it is more useable).
- We also know that the 6D has built in Wifi and GPS.
- The Canon 6D's central focusing square is better in very low light, but the 5Diii has multiple focus squares that do well in moderately low light.
- The Canon 6D's central square also focuses much faster when using a Speedlite AF assist lamp in low light.
Everything else I am seeing, from the other advantages in focusing systems to video quality, true FPS, all the bells and whistles, the 5Diii is a better camera. (The focusing systems are seriously so much better!).
I have been getting a lot of questions about the video quality of the 2 cameras and I can offer this: The 6D's video is not as good as the 5Diii's, especially the moire and aliasing are much, much better in the 5Diii. Whatever it is in the 5Diii that really makes it such an awesome video camera is not there in the 6D. Don't get me wrong, the video in the Canon 6D is very nice and when we start shooting in very low light, the 6D has the edge because of the clean, high ISOs. But having shot thousands of images and hours of videos with the 2 cameras side by side, the 5Diii is the clear winner. However, the 6D makes the perfect sidekick/backup for the 5Diii because of its higher ISO/lowlight focusing abilities. They really compliment each other well.
Another important note is that prices are coming down. While the list price on the 6D is $2100 and the 5D3, should be in the $3300-$3500 range, I am already seeing the 6D available for less than $2000, and in a handful of cases, I am seeing certain retailers sell the 5Diii for as low as $2600 on Ebay. What they are essentially doing is taking a 24-105 kit, removing the lens, selling the body only and recovering the loss on the body by selling the lens separately (which is typically discounted down about $400-500 to sell in the kit).
While an extra $1300 would be a bit of a stretch between the 6d and the 5Diii, $400-$500 is well worth the extra money. Ill have more to come on this soon.
