Backyard Bird Feeder

I had a chance to test out some more of my equipment. This shot was taken from my sun room using the 100-400mm zoom, a 1.4 extender, and my new Gitzo tripod with Wimberly sidekick. While technically this is not that great of a shot I still like that I was able to get this close even with a full frame sensor.

Catoctin Macaque

Today I went on my first real field test of my new equipment. This shot was taken at the Catoctin Zoo with my new Canon 5D and 100-400mm lens.

New Lenses

I have been researching my camera upgrades for some time and made my purchase decisions last week. I placed my order from Amazon.com on Friday and the first boxes arrived today. So I quickly rushed home and decided to do some quick field tests.

This shot was taken with my new Canon EF 100-400mm f4.5-5.6L IS USM lens. These horses are about 300 yards away from my house.

This shot was a perfect chance to test the Image Stabilization since the sun was just starting to set and I was loosing my light. The shot was taken at 400mm at F/5.6 with an exposure of 1/200 sec. and ISO100. With my Canon 300D and a sensor crop factor of 1.6 I had an effective focal length of 640mm.

Common practice is that you should always shoot an exposure greater than your focal length. So for this shot I should have been shooting over 1/640 sec. But the IS kicks in and gave me some nice control of the image sharpness at this slow of a shutter speed.
