Would you go for a more exspensive lower zoom or a cheaper big one, just for the sole purpose of photographing at high alt from the ground?
Hm, I'm not sure if I understand you correctly. If you want to shoot airliners in upper air space only, buy the longest lens you can get (afford). As a rule of thumb, prime lenses are more expensive but also much better in quality. I'm sure the Canon EF
500 f/4L IS
or Canon 600 f/4L IS
would be excellent choices, especially if equipped with a teleconverter, but they are out of reach for the vast majority of photographers, including me.
If you want to spend less money check out the Canon 100-400, the Sigma 50-500 or the Sigma 170-500. Both the Sigma zooms don't have image stabilizers, but that shouldn't be a major problem with exposure times of 1/500s. A lens that is mentioned again & again in forums is the Canon EF
. Also doesn't have an image stabilizer, but it's supposed to be tack-sharp even wide open. With my 100-400 I only use f/8 or even smaller apertures. Otherwise everything looks blurry.
When uploading a photo just type in your credit card number in the remark field. This works wonders!
