Canon 5D Mark II
This is the camera I own and have used most since December 2008. Its 21.1 Megapixel, full-frame CMOS sensor together with Canon DIGIC 4 image processor produces excellent image quality and color reproduction. Noise performance is good at low to moderately high (ISO 800) ISO and during relatively long exposures (i.e. up to 10 seconds). However, newer cameras offer far better noise performance.
The 3.0 inch TFT color LCD display performs very well for a camera of this age. Live View and, in particular, the self cleaning sensor were, to my mind, very useful additions compared to its predecessor, the Canon 5D. But of course these features, and the camera's 9 point AF sensor array, are pretty standard fare by today's standards.
The camera's Flash Synchronisation speed, up to and including 1/200 second, is, to my mind adequate. However, folks expecting to do a lot of outdoor flash photography might well consider a newer model with a faster flash sync speed (1/250 second or higher).
The camera offer's an ISO range from ISO 100 to 6400 that can be expanded from ISO 50 up to ISO 25600. The default is ISO 100, where I use it most frequently.
The camera's full frame format is great for folks looking to get the full scope of their wide-anlge lenses. The full frame sensor always produces a larger image in the viewfinder, compared to an APS sized sensor, which allows for easier and more controlled composition.
I'd certainly recommend the Canon 5D Mark II it for landscape and architectural photography.
A Burst Mode of up to 3.9 frames per second (FPS) allows the user to obtain 13 RAW or 78 Fine quality JPEG files on a single burst. But that's only about half the frame rate optainable from some of today's more sophisticated cameras designed with sports and photojournalists in mind.
Being built around a full frame camera the Canon 5D Mark II is compatable with all Canon EF lenses, but not with the more recent Canon EF-S which have been designed for use with APS-C sensor cameras.
So, while this reveiw hasn't resulted in a 5-star recommendation, its important to remember that this camera has been on the market for over 3 years. And that's a long time in our contemporary digital world. Should you consider purchasing a Canon 5D Mark II, given today's competition? If, like me, a full frame sensor is a critical factor for you (full angle of view maintained with wide-angle lenses and easier composition) then the 5D should certainly be considered.
I paid around AUS$5,000 for mine with the Canon 24-105mm f4 IS lens attached. Its a great all round lens covering classic 24mm wide-angle, through standard 50mm and classic portrait focal lengths of 70-105mm. All that in one lens and, regardless of the focal length you select, the maxium aperture achievable remains f4. Compared to that today's price is pretty reasonable. You're alternative is to wait for the soon to be released, and higher spec, Canon 1Dx or the mooted direct replacement for the 5D Mark II, whatever it may be called.
