I am just about to buy a new lens for the airshow season in the UK. I am looking at either the 100-400 L or the 400 L Prime.
I know it depends on the airshow and how far away the crowd line is from the dispaly line but I am wondering how many shots (take off/landings/slow passes) would be missed by just having the Prime lens. It would be mounted on a 30D so would have the 1.6 crop factor aswell. The Prime is slightly cheaper so would allow me to buy a nice backpack too (KATA). Can anyone give me any advice on shooting with the 400 Prime and wether you missed shots (I know some will be missed) but how many, and were you left wishing for the zoom?
Cheers for any advice in advance,
