Was wondering what a good distance in feet should the bird I am shooting be away before it is too far for a 300 mm lens. Thanks!

About 25 feet is too far for a small bird, just right for a goose. If you use a 50D and are willing to crop heavy, maybe 50-60 feet. But don't fall for the old trap that if you get a 500mm you can sit on the porch and shoot titmice down by the river. even with a 500/4 shooting chickadees, you have to be within 30 feet or so unless you want to crop.

A 300mm lens has a field of view of about 5 degrees.

Get a protractor and draw a 5 degree angle and, in your mind, project that out to your target distance.

Why don't you ask the question : I can get within ______ feet of a bird that is ____" tall. What lens do I need to fill the frame? I think that would be more useful knowledge. Looking at my chart I hand out in my Wild Bird Photography class (yes, send me an e-mail and I'll send you a copy): 300mm (on a 1.6x crop camera) - 60 feet = 3 foot tall bird fills the vert. of the horiz. frame.

These eagles were 1200-1500ft away. I thought I would try with my 50D to get something. BIGGGG crop, but I at least got this to show. We don't get them here much....Rich

I was too close for this guy(25 ft). When he took off I lost him in the frame. The 50D crop 1.6x makes lenses reach better. When I use my5D I rarely get as good results...
