Default my pictures are not sharp

I recently got Canon L lens 28-80mm F2.8-4. Before i used simple cheap Lenses and even now all images are not sharp. They are not blurry but not sharp: L lens did not add anything to sharpness. Cam settings and focusing are correct to have sharp details.

Any idea ?

fast Shutter as described in theory and all F stops where tested, even with good light.
Shutter is at least 125 and higher were tested. I just do not know what do i need to see to call image sharp ???

How to Take Sharp Digital Images

Advanced Tips for Tack Sharp Images

A lot of different thing affect sharpness, not just shutter speed

Stopping down.

Post-Processing

Good handholding technique.

Post an example.

A lens alone does not necessarily make for sharpness.

In addition, the 28-80 f/2.8-4L should be a good lens, but it's discontinued, and has been superseded by the EF 24-70 f/2.8. The 28-80L was first introduced in 1989. Given the possible age of the lens, chances are that someone could have abused the copy you have. Even an L can have a misaligned element if it's been dropped.

Hard to tell at this resolution, but the umbrella & rain look quite sharp in the last image. If you are using a single focal point & focusing on the face, then the camera might be front focusing. If you have multi focal points and let the camera decide, it will usually focus on the stuff that is not important.....

In the first image your SS was too slow for the focal length if handheld without VERY good technique.

In the second issue I do not see an issue with sharpness... If you are beyond 100% magnification while viewing every image will show issues.

It is not terribly uncommon for older "film lenses" to have more issues when mounted on a digital body (front/back focus, CA, etc), especially a "consumer" level body.
