EOS Lens Resolution Tests EOS Lens Resolution Tests

Time: May 2005
Camera: Canon EOS 20D Digital SLR camera with 8.2Mb CMOS sensor
Lenses: Peleng 8mm f/3.5 MC 180° circular fisheye
Canon EF 17-35mm f/2.8 L USM
Canon EF-S 17-85mm f/4-5.6 IS USM
Canon EF 50mm f/1.4 USM
Canon EF 200mm f/1.8 L USM
Canon Extender EF 2X II

The lenses were tested with a Canon EOS 20D digital single reflex camera boby with a 3504X2336 pixel CMOS. Setup was peppered with a Berlebach Reporter 8043 tripod, manfrotto ProBall 308RC and a Canon TC-80N3 remote control timer. Images vere cut much smaller (100X100 pixels) and magnified 3X. The red/white dots representing 17 pixels indicate where the test table lines theoretically could be seen separate. The first two images on each line are saved by the camera as large jpg-files and the next two Canon CR2-RAW-images.
