Hi. I would be grateful for any info/feedback on the following, I have just upgraded from my fuji s9500 (which has had sharpness issues in the past) to a canon 400D which came with a 18-55mm ef-s lens and a canon 90-300mm non usm lens, pleased with the handling of the camera, but the is no way I can get sharp pictures useing either of these lenses, I have tried many different settings within the camera, all my test shots were done on a tripod, trying both auto and manual focus, even my wife,s compact is turning out sharper pics than the canon, has anyone else got the same problem as me, look forward to hearing from you, Rod.

When you say using software - exactly what sharpening are you doing ?

Had exactly the same problem coming off a canon film slr to a 400d .. Answer is as PaulSFrost says , use the unsharp mask in photoshop. Also, shoot RAW and process in Canons own RAW DPP programme (disk supplied with camera).. See my portfolio and look at the first few pics (not sharp at all) and you will see where it changed.

Have you played with the manual focus at all, have a player then compare to auto focused shots.

I`ve never trusted the autofocus of canon.

Hi, I do not have photoshop, I am useing the canon software that came with the camera, i never work with raw always jpeg, mainly because i enjoy taking photos and not get too envolved with pc work, with my previous digi cameras all i have needed to do on pc is a few tweaks to sharpness--contrast-saturation and i had a good picture, but it its not so with this canon, Rod.

I had the 90-300 (non-usm I think) and got very poor results; images taken with the 90-300 certainly require more sharpening in post processing. I always found images to be dull and lacking contrast too.

Probably a combination of things, these are certainly not the sharpest of lenses, but you should get good results, if you don't use the things wide open.

Its difficult to advise without seeing an original image. (I have sent you a PM regarding this)

A quick way to check sharpness is to download the trial version of Breezebrowser. Select View>High Quality the view>Slideshow this should show you the images full screen with a decent amount of sharpening applied. Then you can easily tell if it is the camera/lens or just that you need to sharpen in a different way.

Any chance of sampling a second Kit lens, could be faulty.
