Why do my photos not look sharp pic included....

HI guys I picked up a 7D and a 400mm 5.6 but I am having trouble getting sharp images. I also have a Pentax K5 and have no problems getting tact sharp with that.

for example here is a bird pic I took today I over exposed it because I was told to with the 7d to fix noise and such.  I croped it a bit to lower the image size.

the settings I used was ISO320, 400mm, f5.6, 1/250 and I was using a tripod.

Did you use a cable release (or timer) and mirror lockup?  Have you done an AF microadjustment?

SiliconVoid:
That is simply not in focus.
Hard to tell whether it is a calibration issue with the body (corrected through micro adjustment) or the lens itself as the scene does not leave much to discern a focal plane anywhere.

If you have used the lens on other bodies with desired results, then you could first try changing the focus modes in the 7D.. and work your way to a micro-adjustment for that lens.

If you literally have no sharp images with this lens combination (any subject, any distance) you may want to send both into Canon for lens calibration adjustment.

coreyhkh:
thanks I have some kinda sharp images but I am not sure if they could be sharper, my K5 just seems sharper.
I will look into focus adjustments.

I didn't use a cable I don't have one.

Here is another one I took today does it seem sharp?

The first one is front focused, your shutter speed of 1/1250 sec was fast enough, it should have been ok.
I'd try to test your lens for accurate AF on a static object about 50 feet away.  Use a tripod and take 5 or 6 photos normally, resetting the lens to infinity before each shot.
Then put the camera in live view using live focus, and take another 5 or 6 set the lens to infinity between shots.
If the live focus shots looks sharper, then your camera, or your lens, or both need autofocus Micro adjust.
By doing the tests above, you will know for sure if the focus is accurate.  Live focus is always the best possible focus, it uses the contrast of the image under the selected AF point to adjust focus.  Its slow, but accurate.
