Focal Length

This afternoon I was just playing around in the backyard and wondered about the difference in my widest lens and my longest lens. While I realize the differences between the various focal lengths and lens speeds, I’ve never done a direct comparison between the extremes.

The first photo was taken with my Canon 10-22mm lens at 10mm:

This photo shows a point of reference for the photo taken with the longest lens (the area in yellow):

Here is a photo taken with a Canon 300mm IS + Canon 1.4 teleconverter:

As you can see, there is a huge difference between the field of view between the lenses and a head to head comparison is pretty dramatic. On my Canon 30D, the lenses are comparible to a 16mm and a 672mm. 

A good way to spend a sunny spring Sunday afternoon. 🙂
