I currently have a Canon T2i with the 18-55 mm kit lens. I am planning to purchase the Canon 10-22 mm lens in the next week or two.
That would be it for now. Not sure if I'll get a telephoto lens in the future, since my budget will be pretty much exhausted with the tripod, ballhead and wide angle lens.
In that case the Q3T will be plenty for you. Even if you get a 70-200 itll be fine. Its a very well made head especially for its compact size. Thats whats made it so popular.
