Thanks again for all you comments. Maybe it is just my glasses
When I look at these two photos they look soft (number on mailbox look soft and guard on pic looks soft) (out of focus?). Both photos were taken with the camera set to portrait mode, so some sharpening was applied (didn't realize I was in portrait mode at the time). The mailbox photo was taken with a tripod and a shutter delay. The other pic was handle held with a shutter speed of 250. Both pics were taken with the iso set at 100% and exposure compensation at zero. The jpeg version of both pics were opened in Photoshop, cropped and saved as a jpeg (resolution of 12). Thanks again for you input. I just don't want to have to buy another camera or have my lens calibrated if I don't have to. Canon 30d doesn't do micro-adjustments.
The mailbox shot looks fine, the crop doesn't make it look "soft" optically.
The guard is soft, but it's a crop from an outer edge of an image shot at f/2.8. It has three things going "against" it: first, as has been said, many lenses tend to be a bit soft wide open. Then, many lenses go soft as you reach the outer edges. Third, the wide f/2.8 aperture can have a pretty narrow "Depth of Field" so that if an object is a bit in front of or behind the "focal plane" it can be "soft".
Like I said, that guard is at the edge of your frame. Of more interest is the area you focused on, which would often be at the center of the frame. So, for example, the mailbox was at the center of the frame, and looks fine! I wonder about what you would get if you took just the center of the shot with the guard and looked at it...? 'Course, that would disregard for the time the idea of the lens being soft wide open, but the guard to me isn't soft because of that.
