I have a standard 18-55mm Nikon zoom for normal photography and a Sigma 28-200mm zoom still from my old Nikon F4 35mm equipment. Sigma is an excellent lens, but 200 mm is just too short for in-flight photography, in particular of smaller planes. For Airbus A380 it works fine, but even an F-16 is too far away during air displays.
Sigma 80-400 is offered for a special prize, but I have already noticed it is bulky and heavy!!
