Read what actual EOS 5D (Mark 1) owners have to say about their experiences with the camera.
- Why Brandon Berg ditched his 30D for the 5D
- The 30D has posterized noise even at ISO100.
- Vignetting on the 5D is only an issue with wide lenses, and easily corrected. The 5D would be great for ISO1600 / ISO3200 shots printed at 8x10.
- There is only mild vignetting at 24mm when using the Canon EF 24-105m f/4L IS USM. The 17-40mm lens does very well, with only a little vignetting at 17mm.
- Superior images from the 5D can be had even at high ISO — see 2 samples, one at ISO1600, and another at ISO3200.
- The Canon 5D vs Canon 20D in matters of DOF (depth-of-field) — view 3 crops comparing 5D, focal length of 100mm @ f/2.8, vs 20D, focal length of 50mm @ f/1.4, vs 5D, focal length of 85mm @ f/1.8. The 5D also has much lower noise, even at ISO1000.
- The 5D has better dynamic range, and yields sharper images, than the Canon 10D and 20D.
- Autofocus performance; 5D vs Canon 30D: The 5D is much faster in AF, making it more suitable for sports / children activities.
- More pixels for cropping: If choosing the 5D over the Canon 30D, this is an important factor to consider.
