Aurora time lapse



Aurora time lapse, originally uploaded by fyngyrz.

This is 40 still frames from my EOS50D, taken the evening of the onset of the April 3-4-5-6 geomagnetic storm, all from the same point and with the same camera settings. I used Canon’s 50mm ƒ/1.4 lens, wide open, after manually focusing it on a star. All these shots were taken at ISO 3200, 4 seconds exposure, then combined using the Mac’s movie software and converted from .dv to .mp4 using Handbrake, and from thence to flickr.

EOS 40D to EOS 50D changes – All of them – In a Nutshell

For most 40D owners, the issue is simply: What has changed? I took a hard look at Canon’s specifications, press releases, and an early preview, and here’s the scoop:

Canon leaks EOS50D details

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.

Review: Canon EOS 40D

I’ll start off by saying that yes, the EOS 40Dreally is a great camera. I bought it as body only, then added a Canon EF 100 f2.8 Macro USM lens. If you’re not familiar with that lens, it is fairly heavy, and so the camera has felt heavy to me since day one. But it was the lens creating that impression.
