finally figure what is wrong with my EF 24-70

[mr_sub]

please do not laugh if i tell u this--

my wife set the iso to 1600 when she played around with my 30D. i did not realized it and all my test pictures were taken at iso 1600. i found lot of strange colored dots in the picture and i thouhgt it was the lens. Tonight I shot the same thing with iso 100, excellent picture taken.

Now i am happy with the lens and remembered Ronald said mostly it was the user error.

Let me show how iso 1600 can destroy a good picture, I took this one below I liked very much this afternoon, it has go to the recycle bin because of the iso setting.

if u look at the pic at a small size, it is not too bad, but with 100% crop you can find lots of dots, here--

Oh goodness, keep that one. It's nice! How often are you gonna look at it that huge that you see something like in that crop? Keep errrr.

a comparason of iso1600 and iso100. me as a beginner, i will try to set the iso always below 300 to be safe. unless i can find a good way to reduce the noise it creats.

No offense to those that don't/can't have a 5D, but that's what I love. I don't have to limit myself on the ISO. 50-3200, it's just awesome. Get the exposure, and you'll have next to no noise, no matter what the setting (that goes for the other models, too!).
