thumb|Canon EOS 5D
Die '''Canon EOS 5D''' ist eine digitale Spiegelreflexkamera (DSLR) der Marke Canon. Sie verfügt über einen Vollformat-CMOS-Sensor mit 12,8 Megapixeln, einen 9-Punkt-Autofokus und einen hoch auflösenden 2,5-Zoll-LC-Bildschirm. Die 5D ist kompatibel zu allen Objektiven mit Canon EF-Bajonettverschluss und wiegt ohne Objektiv 810 g. Markteinführung war im September 2005.

Erst im Juli 2008 erhielt sie durch die Nikon D700 Konkurrenz in der Klasse der semiprofessionellen Vollformat-DSLR.

The '''EOS 5D''' is a 12.8 Canon. The EOS 5D was announced by Canon on EOS 40D but below the EOS 1D Mark III and EOS-1Ds Mark III in Canon's EOS digital SLR model plan and price range (though all these models surpass it in some measures of performance, such as frame rate). 

The EOS 5D is notable for being the first full-frame DSLR camera with a standard body size (as opposed to the taller, heavier "professional" camera body style). It is also notable for its price, introduced at just over $3000 USD or £2000 GBP, which set a significant new low price point for full-frame DSLRs; its only full-frame competition at the time was the Canon 1Ds series of cameras, which cost more than twice as much. The price for the body has since dropped more than 30% (down to under $1800 USD in July 2008), keeping the 5D the least expensive full-frame camera on the market.

The full-frame capture of the 5D allows for relatively low-noise photography at high ISOs.  This  allows users to take pictures in low light, and also captures high levels of detail in the shadow areas of bright frames.

== Features ==
The EOS 5D features:
* 35.8 x 23.9 mm full-frame CMOS sensor
