got a friend over in Hawaii (met on the net a few years back) that has just picked up a new 10D (came from a sony 707) and is at this time using a 50mm f/1.4.
needles to say he is in awe, but wants a wider zoom.
i told him i'd post here so i hope there will be some responses.....

thx

This is the kind of pictures I get from my lens:

Taken at f/4.0

Reduced to 25%:



Left side 100% crop:



Center 100% crop:



Right side 100% crop:



I can't get anything sharp that is further away than 5 feet.

max...sorry but i can't bring up your pictures. am also sorry you got a bum 17-40. return it. mine is razor sharp at all focal lengths and the f stops that i use (5.6-11). on the other hand my 16-35 sucks and has been religated to a snap shot roll. you would think that there would be a high level of quality and uniformity at these prices.

I finally purcahsed a 17-40L a couple of days ago and didn't have a chance to test out its landscape optics until after work today. The following two pics were taken around dusk in a wooded local park. I am by no means an advanced photographer and have alot to learn. I just want to know if the two pics below at least demonstrate that my lens copy appears to be reasonably within the standard of the 17-40 (even though I didn't have optimal lighting conditions.) Please note to click on "New window" above the picture to get the full scale of the picture. Thanks!!

Hi Mike,

it's not possible to judge the quality of your lens if you don't post 100% crops or a link to the original image. Clicking on 'New window' just shows the posted image as it is - you get same result if you click at the image itself.

I would be very interested to see the original, as I have a quality problem myself with my lens as you can see above.

max...if this is the best it will do you must return it or have it fixed.
 
when i was testing the 2 17-40's my camera shop had, i took shots with each from the same spot in the store where i rested the camera on a counter and shot at 17, 24 & 40 mm at f/4 and f/8...............in this shot you will see a part of the counter and no, it is not a lens blur it is just what you will get when shooting from the top of a counter with the focus set to quite a distance................when it came down to a decision, i picked the one with the least visible CA which i only saw at most when shooting at wide open and at 17mm.

i took shots from outside the store as well, and i can post a picture if need be, but even though i'm happy with this lens, i have shots that look sharper and less sharp as well when viewing at 100%. this is to me where people get frustrated.............if you are going to print a full size image, then you need a big printer, but the fact reamains, and this is from the Canon EF Lens Works III book, that canon says their lens are optimized for 11x14 inch prints. i do have pictures that look somewhat fuzzy at 100% viewing, but printed at 8.5x11 they are really sharp.
here is the test shot..........

hey Tommy,
did you shoot this handheld?

I was leaning against a rail and the exposure was 1/2000 s, so
motion blur is not a factor here. And I've taken lots of test pics
on tripod with timer with exactly the same result.

this doesn't really look that bad, considering you've posted a 100% picture of what is considered a landscape shot...........my shot's like this are no better, and after a lot of conversation on other boards with other users of this lens and D60's and 10D's about why details so far away aren't as sharp as i thought they should be, you have to remember that these cameras are 6MP, and although it's enough to compete with film, it surely isn't enough to capture the detail we see when shooting subjects at close range..........this is why people that are serious about landscapes use 5x7 or larger cameras.

Hey, that's a very cute kid! And that Chevy looks nice too.

I didn't have any suitable pic form around 10 feet at the moment
and I cant take one just right now - it's midnight here!

But meanwhile you can take a look at this one. Full size at f/5.6.
