<p>William, <br> 1/500th at f2.8, iso 200<br> canon 5d mark3<br> no filters except a Pro Optic MC-UV filter<br> yes handheld. <br> i was also using a 1.4x extender, the canon one, which originally I thought was the problem; but the same issue exists without the extender.</p> <p>Stephen, the sharp parts of the image do not have this issue; and no other lenses have shown this to be an issue, so I don't think its the camera.<br> I wish I could post more pictures but its limiting..is there another place to do that?<br> Thanks guys -<br> Roey</p>
