Why 35mm? Why not Digital?
Part of my side business is photographing airplanes and parts. Using even a mid level Fuji 602 Zoom gives better results on average than does my Cannon EOS Elan 7E. The difference is the processing. Few of us have darkrooms and getting professionals (not at the local Drug store ) to handle your film is expensive. For a few hundred dollars you can have a nice system for printing your own pictures and making enlargements.
Besides, it costs so much to do aerial photography, you need a back up. Can you imagine a photo shoot that cost thousands to arrange being spoiled by bad film, or an accidently formatted memory card?
With the recent crop of $1,500 5MP cameras, including an excellent EOS model from Cannon, why shoot film? Film is an out of date anachronism. You can use your Cannon EOS lense system (Nikon whatever) with the new Digital cameras that are based on 35mm bodies.
Also for aviation work I have Cannon's 100-300 IS USM lense. The image stabilization helps in light turbulence for air to air work, although shutter speeds are usually high enough to make this less of a problem, it is a great lense for the money.
Another thing to consider is batteries. Maha chargers and Powerex batteries are the best and will save you money and headaches as you use your system.
I will try to find you some links - but in the mean time search Thomas Camera Resource pages and use their links to price equipment over the internet, you will save around 30% off the prices at the big camera stores.
