Hello, what is / are your goals suggested that there are Canon L series? Can you suggest anything for me? And also, What is the difference between EF and EF-S? They are EF-S is better? And are those better buy than those with none? thanks! Oh yeah, I forgot to mention about the USM, what about USM lens has it? may also suggest some telephoto

Any lens Canon L-series is not yet a target pretty good. The main advantage of the L-series lens is build quality, most optical quality and constant aperture lenses L have. It can be frustrating in some situations where the shutter speed decreases as you zoom in, say, from 18 mm to 200 mm. Canon In my opinion kind of messed up with the EF and EF-S mount objectives. The difference is that an EF can be used on any Canon – Rebel line from the sensor of 35 mm cut line to line DSLR SLR full-frame digital. The EF-S mount only be used on digital SLR cameras cropped sensor such as XS, XSi, T1i, 50D and 7D. IS – Stabilization image – is useful when you have no choice but to hand-hold the camera when using a slow shutter speed. Exceeds used induced camera shake / Movement. SE has absolutely no effect on subject movement. Unless you plan on doing a lot of pictures in low light handheld that can probably be do without IS.

Does Nikon have a professional line of lenses that Canon L-lenses?

I saw nothing on the professional line of lenses for Nikon. I do not know if something like the L series lenses What is your friends who own Nikon and Canon?

Nikon did not label their professional lenses Nikon Pro lenses. They are nearly all its f / 1.4 (or less) the primes, and the constant f/2.8 zoom. With his glasses fixed lens, the f/1.4 85mm lens is a fantastic portrait. With a zoom, the Nikon 17-35mm f / 2.8 is the best scenery of any brand. The Nikon 55mm f/2.8 17-is an excellent choice for journalism. The 70-200mm f/2.8 and 200-400mm f / 4 is ideal for sports and wildlife. The 500mm f / 4 is even better and have many other options. As expected, all these goals cost more than $ 1,000. Personally I use a Nikon 17-55mm f/2.8 and construction quality, and keep me as a incredible image. PS ED "AF coating speed is not restricted to Nikon lenses. Even the kit lens supplied cheap 18-55mm for the D40 is an ED lens.
