My rented Canon 17-55 just happened to arrive as I started typing this.  So I plan to give it and my Tamron a side by side challenge this weekend.

Thanks for the very practical advice.

By the way, which 70-200 do you have?  Are you pleased with it?

Please share your experiences with the 17-55 vs. your old Tamron.  It'll be nice to see how they compare.

I've gone through three 70-200 lens:

1. 70-200/4L non-IS --- upgrade from 75-300 non-IS.  Real eye-opener on color, image quality, etc.  Was so sharp, I can clearly see how I could benefit from IS and so sold it to a friend within a month

2. 70-200/4L IS --- awesome lens.  I regret selling it to help pay for a 70-200/2.8.  This lens is lighter and a bit smaller.

3. 70-200/2.8L IS II --- aside from the size/weight of a f/2.8, this lens really rocks optically.  It comes close to a 135L (although can't match the 135's bokeh) and a 100L macro (at long focal lengths of course).

In short, I do recommend the 70-200/4L IS, 70-200/2.8L IS II.  I can also see getting a 70-300L instead of a 70-200/4L IS.

For maximum sharpness, I like the option of IS.  I'm not at my best at the end of a long day of shooting as it is.

In your opinion, is the f/2.8 worth the extra cost?  For me, I use my cheap Canon 75-300 for outdoor photos--landscapes, my child on the beach.  So, my initial thought is that I wouldn't necessarily need the f/2.8 (especially with the price difference).

And I will definintely share my comparison of the Canon 17-55 with my Tamron.  I can probably post the photos too...just have to figure how to crop them with my software and post them.

Thanks for all the advice so far!
