How do these lenses compare...?

I have just done a little test, and the results are obvious.. mind you so is the price :)

I am not sure I will be too tempted to go back to the 28-135.. but i will see what the finances allow :S

Fixed the thread title :-)
The difference is pretty easy to see, and that's interesting since...

- The shots are at f/8, which should equalize things to the greatest degree possible
- The shots are at mid-zoom, where again you're not pushing the lenses at all
- The corners don't represent the worst case, there's a lot of image circle still outside the 10D frame

The performance difference would be much greater toward wide open, and at the extreme edge of the image circle. Then again no real surprise, the 24-70 is one of the best-performing midrange zoomes on the market, and has it's stellar reputation for good reason.

yeah, i didn't think about the fact that it would no doubt be worse on a full frame sensor. It is painful to know that there is almost no point in taking a group shot with the 28-135.. it is guaranteed that the side people will be blury :(

And yeah I was really trying to see if they would be differnt on 'perfect' settings for both lenses. I am still going to add to the review and include wide open aperatures and the end of the zooms and such. It will be interesting to see how bad the 28-135 will get :) or perhaps it will just stay consecutive with the differance there is now.
