My Menu

The 'My Menu' feature on the EOS 5D Mark II allows you to produce a custom menu made up of any of the cameras menu options (including custom functions) which means that previously buried but useful options such as Mirror lockup can now be brought to a top level menu. The menu can even be arranged so that the options appear in the sequence you find most logical.

Great Camera. Its "just work".


It has shown its great value over money.


I work in Nyc as a fashion photographer and I have to say the the 5d series are the most used cameras out side of medium format cameras .Ive been shooting with the mark 3 for over a year after shooting with the mark 2 for 2 years great both great cameras. You can see the shots I've taken with it for my work on my website hope it helps!! also note I only shoot RAW format.

Was it really 2009? I'm still in the first flush of my love affair with this camera. And I'm still fathoming the depths of its capability. Okay, she's got a lot of paint missing these days, but the images are still magic. Whenever I use another camera, I sigh and wonder why I didn't use the 5D2.
A brief history of photography:

silver chemistry

flexible roll film



5D Mark 2...


As I know when the original 5D debuted three years ago, it wasn't clear why most enthusiasts would want such a camera. Though it captured excellent, high resolution images, it was slower and bigger and more expensive. Today the market has changed significantly, and it's clear that the market is ready for full-frame digital SLRs that can turn out high image quality. High quality is one thing, but being a camera that can deliver high quality over a wide range of lighting conditions and different ISO settings is what makes the Canon 5D Mark II such a compelling choice, and a clear Dave's Picks.
It's really very very good.
