Canon 5D/100-400L IS vs. Panasonic GF1/45-200
Jan 16, 2010

Truly well-controlled camera/lens comparisons are difficult to do, and require studio setups with controlled lighting, standardized targets, cameras on tripods, etc. I wasn't prepared to do all that, but I wanted to do an informal comparison between my Canon 5D with the 100-400L IS mounted, and the GF1 with the 45-200. Considering the crop factor, the 45-200 is equivalent to 90-400, and the maximum apertures are the same.

What I did was to set the lens of each camera at maximum focal length (400mm on the 100-400L IS, and 200mm--400 equivalent--on the 45-200), aperture set at 5.6 (the max. on each lens), IS on for both, ISO200, and took four hand-held photos of the garden shed in our back yard, aiming at approximately the same point.

I shot RAW, processing the images with ACR5.6 and PE8, using the same settings. I compared the four images from each camera in FastStone, and picked the sharpest image from each for the camera/lens comparisons.

The first picture shows the two cameras/lenses, to give you an idea of how they compare in size. What follows is a pair of images resized to the standard 1024 pixels wide (the aspect ratios are different, so the vertical size is not the same), first the 5D/100-400L IS image, then the GF1/45-200. Below that is the second pair of images, 100% crops, first the 5D then the GF1.

What do you think?
