Here is one of mine taken with the same lens @ 300mm:
This one had some USM applied to it in post processing, but nothing extreme. |

| Looking at the water in the background of the bird it appears that a pretty good breeze was blowing. Wind can cause camera shake also, maybe try weighting your tripod down or don't extend it to full height. |

This supports the "soft lens" theory, this isn't very crisp at all compared with, say, the Canon 70-200mm...

Here's a fairly heavy crop of a 200mm shot with the f/4L 70-200, tripod-mounted in a 35mph wind at 1/500 shutter speed and ISO 200. Considerably sharper, and even so marginal by my standards...

The picture I have used in this example (the egret) was hand held, taken @ 300mm with an apreture of 5.6@ 1/160.... But i have plenty of others that were on the tripod at 300mm that look identical to this. I think Bears shot with his 200mm is million times better than what my lens accomplished.
Thank you srdanz for supplying a photo from the same lens... now I know I am not going crazy. And thank you again to bear who attempted to sharpen the photo.
I think I will just end up switching out the lens. does anyone have any experience with this lens: Sigma 120-300mm f/2.8 EX APO IF HSM for Canon AF
I would appreciate feedback on it so I can make the right decision for me.
Thanks for all your help....
This is what makes DPC great.

In the meantime (until someone replies) you can check out Equipment library - whomever uploaded a shot in their portfolio or for a challenge, and marked the lens (correctly), that shot would show up on the lens' page.
Here is the Sigma you're querying about.

ps. I gave my 75-300 as a gift (with full disclosure of image quality). |

Thanks srdanz, I was pretty much thinking the same thing. My wife likes to take photos as well, but she likes to take the family things that will never be blown up bigger than 5x7. I think it would be a alright lens for that purpose.
Thanks to all who have replied.

Stopping down helps a bunch with this lens. Here are some taken at f/8 with a 75-300 IS:
100% crop:
However, this image has been pretty heavily processed.

does everyone still use USM versus SMART SHARPENING in ther new PS CS2?
It seems that everyone still talks USM, are there advamtages using the older PS technology over the newer Smart sharpen that can still be controlled very effectively? So where would one find the "Canon recommendation" for smart sharp or what is the equivalent to USM 300%, .3 and 0. Seems Smart sharpen has all those controls. Thanks. |
Well, for one, I don't have CS. I stull run 7.0. I am taking dontations for the upgrade though LOL
As for why canon recomended what they did, i don't know. Canon's tutorial and more site is here.

Crank up your shutter speed.
When i used my Sigma 70-300 4-5.6 APO Super 2 ($189 or so) I had sharpness issues at longer lenghts - turned out to be camera shake. Cranking up the shutter speed to 1/800 or more solved the problem.
At 300mm, handheld.
