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. https://skydrive.live.com/redir?resid=DD2F380E99727744!1314
