Canon Lens Usm
What is the effect of the USM in the Canon lens in the photo is taken? is a quasi-one is IS?
I'm confused between the kit 18-55mm or 17-85mm IS kit IS USM. Becoz the price difference is quite large, suppose that USM is really important.
USM is an ultra sonic motor. It's essentially an engine fast quiet focus allows full time manual focus. It's nice, but by no means necessary. I would not worry at all.

The Tamron AF70-300mm F/4-5.6 or the Canon EF 70-300mm f/4-5.6 IS USM …. What is the best?
I have a Canon 20D and 10D digital camera. I an Old Canon EF Zoom 75-300mm 1:4-5,6 I bought in 1996! So I know that this goal was never designed for digital SLR cameras. I'm on a very limited budget, so I need to know which of these lenses is better. The Tamron is available to me more so USM Canon. But I want to get the best of both. Absentmindedly more expensive objective function better. So my question, which of these two is the best objective to invest in.
If you have money, lenses made by the same manufacturer as your camera – Canon in this case – are almost always a value from a third lens. You can save money by purchasing Tamron or Sigma or any other, but the glass, build quality and performance are quality generally less than Canon.
