The Canon EOS 5D Mark II Digital SLR is an earlier iteration of the vastly improved 5D Mark III. The 5D Mark II is not without its merits, however. It's a hair lighter than its updated counterpart and is still a rugged full frame option that is less expensive to rent, thanks to its age. The 5D Mark II is known for its durable shutter, which is why it is still the beloved camera of many photographers. It is perfectly suited for portraits and weddings (though the 3.9 FPS will leave much to be desired if shooting a lot of action). High quality lenses, such as the Canon EF 24-70mm f/2.8L USM II Lens or the Canon EF 70-200mm f/2.8L IS USM II Lens (rentable separately) pair well with this camera but please note that EF-S lenses are not compatible with this camera.
