OK, the general rule for sizing focal length depends on the subject size, subject distance, and sensor size:

Subject width / subject distance = sensor width / focal length

Which gives us focal length = sensor width x subject distance / subject width

Exciting maths.

Hehe.

They provide an excellent overview of what it is all about.

Some folks these days go as far as calculating the angle *per pixel* to select both camera and lenses, with smaller values giving more "reach". There is some point where it doesn't make much improvement, even with a great camera and especially a great lens, because then you'll worry more about atmospheric haze and heat waves distorting the image.

I'm afraid there's no way around saving for the right lens - around 500mm ...!

Yeah, that sounds reasonable.

Be sure to look into teleconverters, as you might be able to get by with a shorter lens, but the best ones are matched to the lenses. Cheap ones are more useful as paperweights.

Finally, if the price of a lens is too much, you might look into a superzoom camera. The image quality might not be all that great at long zooms, but it might be possible to actually get the shot.
