Mark Goldstein from PhotographyBlog published an in-depth review about Canon's latest semi professional full frame digital single lens reflex. His review covers the 5D Mark II's ease of use, how is the image quality and ISO performance. Sample photos are available too for reference purpose.

Some extracts from the review:

Image Quality: There is no discernible noise between ISO 100-1600, and ISO 3200 also looks very good. Noise is more apparent at ISO 6400, becoming progressively worse at ISO 12800 and the fastest setting of ISO 25600, but it's still very well controlled with images suitable for small prints.

There's virtually no visible noise at all from ISO 50 all the way up to ISO 3200, with even the three faster settings of 6400-25600 producing perfectly usable images. Canon seem to have matched the low-light performance of the Nikon D3 and D700 whilst substantially increasing the resolution.

Comparison: The 5D Mark II doesn't stack up too well in terms of continuous shooting speed or autofocus points when compared to the Nikon D700, and viewfinder coverage to the Sony A900, so you still need to carefully consider what you'll be mainly using the camera for. It definitely offers more than enough new features and handling improvements to tempt original 5D owners to upgrade, substantially refining what has proven to be a big hit for Canon.
