Canon’s successor to the EOS40D is now a matter of public record.

The most important issue for me as an EOS40D owner is the degree of light sensitivity the new model camera offers; the 40D goes to ISO 1600 and will “push” to ISO 3200. The 50D goes to ISO 3200 and will “push” to ISO 12800, which is a huge improvement, particularly for wide-field astro photography which is an interest of mine, but also for low-light shooting in general. Higher ISO capabilities extend the range of situations any lens can be used in, a very welcome upgrade.

Among the sample images is one of a race car that was shot at ISO 1600; examining the dark areas of the shot, much less noise is evident than I would have expected based on my experience with the 40D. This is hugely encouraging.

The leak exposed a number of photos and diagrams that relate directly to the EOS50D; you can view those here, in a new flickr group I’ve created to support the camera and its users.
