I just got my new ef24-70. I am very disappointed with the quality of the pic i shot with it. So disappointed that I have use it to compare the EF 18-55 which comes with my 30D. I compared at 50mm with f5 and f10 and all pictures took on a tripod. When I looked at the pictures at computer, I could not see the difference if I did not looked at the file name. They are identica, at least to me.

Anyone has any idea why this 12 times expensive, much larger and heavier lens produce the similar quanlity as the much cheaper, smaller and lighter lens?

Have I got a wrong sample of 24-70?

Thanks

Not sure how you are testing but the best way to see differences are with flat high contrast targets, try using newsprint taped on the wall if you not doing so already. AF has some statistical variation so throw the focus off and re-AF say three times and use the sharpest of each case.

The kit lens is at its worst at 50mm so you should be able to see a difference. Differences will be greater in the corners. Don't have a 24-70 but here is a 50mm prime comparison.

I loved the one I had for a couple of days... I regret having to let it go. It wasn't mine though and I bought it for someone else on this board at a local shop and got to test it out for him.

I kind of thought the same thing when I first got my 24-70mm. But after some handling the lens for a while and "getting used to it" it came into its own.

It's definitely a good lens that's been tried-and-true for reporters and wedding photographers for a long time, to name a few. I've gotten very nice results from it, and it's basically my leave-on-camera lens for everyday use.

I literally had to RUN through WDW and Epcot as I only had until around 7pm before I had to catch a flight back to NY. It was basically, "ooh nice, snap, walk, snap, ride, snap snap..." while constantly on the move. I think the shots came out pretty well:

Same thing in Washington D.C. - I only had a few hours and ran through as much as possible, snapping on the move:
