I got this camera a while ago, and i love it to bits lol, but for some shots i have the planes too far away or blurry, what is the best camera from somewhere like ARGOS or DIXONS thats cheap (around £200-£300) and better what kind of zoom should i be looking for for a airport picture.

Another quick question, i got my prints developed and some pics turned out with orange over them, or some with a orange bar at the top, is it my camera or just they way theyve turned out...
