12.8MP full frame sensor 3fps burst mode 9-point AF mode 2.5inch LCD Magnesium alloy frame The Canon EOS 5D, predecessor to the EOS 5D Mark II and Mark III, is a full frame DSLR capable of taking high resolution images as well as offering a build quality and feature list perfect for the on-location professional looking for a comparatively light, well specified DSLR. The standout, headline grabbing feature of the Canon EOS 5D is the full frame sensor, which is the same dimensions as a 35mm film negative. This gives the camera a distinct advantage over the APS-C cameras like the Canon EOS 7D, as it boasts a far larger surface area. For the professional this quality is a necessity, as more light can be captured by the sensor, leading to a cleaner, more accurate exposure. The Raw files are especially useful for in depth editing due to the huge amount of information retained in each uncompressed file. Having an ISO range of 100-1600, which can be expanded to 50-3200, as well as a 32 zone metering system the Canon EOS 5D is well suited for low-light and landscape images, especially as the size and weight make it more portable than an EOS 1Ds series models. The Canon EOS 5D can take up to 3 frames per second for up to 60 JPEG images, making the camera able to capture subjects through a range of movement. The 9-point AF system can be employed in this situation as well, tracking the subject by switching focus points automatically if desired. Shots can then be reviewed and magnified using the 2.5inch LCD screen, and a day’s photography is straightforward to review. High quality and lightweight due to its magnesium alloy frame, the EOS 5D is the perfect introduction to full frame photography.
