Whenever I upload images from my 50D , they never look sharp until I sharpen them in DPP. I have the sharpness turned up on all my picture styles and they still look dull. This is for JPEG and RAW. Any ideas???

Sharpening of an image is an integral part of the process whether jpg or raw. Sharpening is always dependent on the method of displaying an image, a print will be sharpened much more than a web shot, a image of a person should be sharpened less or much more selectively over a subject like a bird, a down sized image for use on the web should be sharpened after the downsizing.

There are a mutitude of sharpening processes, applications or methods dependent on the subject matter, use and image type because of this sharpening is a skill set that many have issues with and usually just default to a single process or method and a single set of settings in their post production.

It is almost always best to turn the sharpening in camera down to a moderate level and then work the best out of the image in post production. However if a quick turn around or sharing of the image is required then using the higher settings for a jpeg can have only adequate results at best.

Could you flick us a couple of examples with EXIF intact??

You're not doing something right.

Seriously, you have given us absolutely nothing to go on here. A dozen or so factors contribute to image sharpness.

A few samples, plus 100% crops of detail areas, with EXIF data, might be a good start.

I had the same issue with my 50D when I bought it. This is what worked for me.
First off, make a isolated test, and try it with different lenses. Also use a tripod to make sure your not shaking . Removing that out of the equation helps.

Check the images from different lenses to see the sharpness. If you find some lens are soft and others sharp, you may need to adjust your microadjustment to correct for front and back focusing. Do a search on this forum for the method to correct the adjustment.

After i did this on my 50D, every image is sharp and by far produces the best images i have ever had from any of my Canon cameras.

Unfortunately, Canon didn't give a great deal of documentation on how to adjust this in the manual , but thanks to forums like this one, there are plenty of users that have performed it and it helps.

Not saying this is foresure what is wrong with your pics, but something to consider.

If you shoot in jpeg, you can adjust the picture style for the sharpness to 7.

I don't think it's a problem with you camera having blur pics, more of shooting with the correct techniques.

Try again, with any of your lens.

- Step down 1 or 2 stops on aperture. (eg. f/2.0 or f/2.8 for your 50mm lens)
- Select a shutter speed at least 2x your focus length. (eg. 1/100 shutter speed for 50mm lens)
- Make sure your exposure is near mid point, else tune up the ISO.
- Hit the shutter and download to your PC to view.

My 40D was capable of excellent image quality, not to say your newer 50D.

Have you tried some AF Micro adjustment?? This worked for me on my Sigma EX 50-150mm f/2.8 APO and Canon EF 50mm f/1.4 USM..Now both lenses are brilliantly sharp..
