Name brands don't really tell you much.

Price tells you a lot.

For instance, the Sigma 70-200 F2.8 lens is nice, and it costs around $700.

The Canon 100-400 IS is a nice lens, at about $1400 US dollars.

You won't find a Nikon or Pentax lens that will be compatible with your Canon lens. You WILL find third party lenses (Sigma, Tokina, etc.) that are. Some folks will recommend you stick with lenses made by your camera's manufacturer, but there are some very good lenses in the marketplace made by third party vendors. Just make sure they are compatible with your camera before you buy one.

Each camera manufacturer makes a unique mount and that's where the compatibility issues can arise, especially with some older third party lenses. Sigma has a good reputation for "re-chipping" their lenses to overcome any issues.

If you have a Canon camera, you can feel confident any Canor EOS lens will work fine. Ditto current Pentax lenses with Pentax cameras or Nikon lenses with Nikon cameras.

One trap is that Canon EF-S lenses only work with Canon 20D, 30D or Digital Rebels.

Most of the camera manufacturers make cheap lenses and top quality lenses, likewise many of the after market lens manufacturers have a quality line and a cheaper line.

A top of the line Sigma, Tokina etclens will be a better lens thana cheap Nikon or Canon lens. A top of the range Nikon, Canon etc lens will cost more than the aftermarket lenses and may just have the edge on quality but not always.

Best advice is to try to read as many reviews as you can and decide on what is best for you in terms of costand quality.

I want to repeat something that was said:
"and decide on what is best for you in terms of costand quality."
(emphasis is mine)

You shouldn't waste money and that goes both ways. If you buy a really cheap lens you will waste that money and be unhappy with your purchase. On the other hand, if others tell you that you must have some really expensive lens it might not really be what you need. Sure, it will do the job but something cheaper might be too. And the more expensive lenses are often ones with larger apertures and therefor are heaver. A high quality but heave lens is nice... but a good quality lighter lens is even better! Some times lighter matters more than utmost quality.

Yes I agree with Eric.

The best camera is the one used most often.

The best lens is the one used most often.

I think that the 50-200 will be sharper. I don't know how important that is to you, and I don't know what subjects that you want to photograph. A 75-300 is not long enough for bird photography, and is marginal for large mammals.
