Lens Help Please

I have a Canon A80 and am now considering a Digital Rebel DSLR. One thing I
am unsure of though is how to determine which telephoto lens I would need
for the DRebel. If I am shooting small birds at a distance of 20 feet what
would I need to ensure the image filled the frame. Can somebody point me
towards a good web site which explains so that I can learn for myself.

Thanks,

Andy

http://www.sweeting.org/mark/lenses/ has a lens field of view
calculator on it.
A 200mm lens will give you a field of view of 30cm at 3m subject
distance, 300mm takes it down to 20cm so this range would be good for
small birds.

I like the Sigma 55-200 which starts off where the kit lens ends
(18-55). I just got my EOS Rebel 2 weeks ago and picked up this lens and
love it. It's the Sigma DC 55-200 Digital Series.

How much do you want to spend?

A 300mm lens would probably do the job. Keep in mind that on a Digital
Rebel, this is actually a 480mm lens due to the 1.6x factor. For an
inexpensive lens, check out the Canon 75-300mm EF USM without IS. B&H Photo
(www.bhphotovideo.com) has this for about $160. If you want IS (image
stabilization), then I recall that it is closer to $400. IS is great if you
want to hand hold the camera rather than use a tripod. I have this lens and
do like it. I do not have IS. What I have found that is in daylight, I up
the ISO to 200 or 400 so that I can use a faster shutter speed. This helps
to resolve camera shake. A tripod is always better, but sometimes I want
the shot and I do not have the tripod with me.
