Need a good replacement for my kit lens...

[skraw]

I have a Rebel XT and just ordered a Canon 40D. I am in need of a good upgrade from my kit lens (18-55). I'm thinking of the Canon 17-55 2.8 IS USM, or the 16-35 2.8 USM. Any ideas or recommendations? Any thoughts on Tamron or Sigma?

OK, have my 40D now, love it! But does anybody have any advise for a replacement for my kit lens?

i know the 16-35 is popular. ive seen a lot of 17-70's from sigma, i think, as well. not sure how good they are though. i use my kit still. :/

It is really a hard thing to give advice on. It all depends on what you shoot, your budget and what focal lengths your after.

The Canon 17-55 2.8 IS USM is an EF-S lens, which means it will not work if you upgrade to a full frame camera. These lens are specifically designed to work on crop camera such as the 40d. You may want to keep that in mind.

Depending on your budget, I like 2 lenses.

Tamron 28-75 2.8 is an AWESOME lens for someone on a smaller budget. This this is really sharp and has a constant 2.8 aperture.

You could probably get one for $350

My all time favorite lens is the Canon 24-70 2.8 L. For me it has the perfect focal length on my crop camera for what I like to shoot most. It is razor sharp, built like a tank, and incredible focus speeds and accuracy.

Usually around $1200, so it may be out of reach for most, other than the serious amateur or professionals.
