Warning, not the most scientific test ever! It was done for us to see how a budget, mid and high priced setup would compare. The first three video samples feature each camera with a different lens. The final test features the Olympus Zuiko 35mm f2.8 OM lens on each camera as a way to compare the image quality with the same glass. No color grading or post treatment. Native H.264 clips straight into Premiere CS5 dslr 24p sequence. Rendered with Media Encoder to Quicktime H.264 Codec Re-rendered from Quicktime to H.264 High Quality Auto Bitrate to make smaller file size for Vimeo upload. All Clips shot at 24 fps, ISO 100, Neutral Picture Profile and Daylight white balance. Lenses used: 550D = Canon EFS 18-55mm f3.5 - 5.6 IS 7D = Tamron 17-50mm f2.8 5Dmkii = Canon EF 24-70mm f2.8 L Final shot: All 3 Cams = Olympus Zuiko OM 35mm f2.8 We hope this little test is helpful to video DSLR newbie's and people wanting to purchase one of these amazing cameras.
