Those porn videos inspires me to bring my camera out tomorrow.

If you need telephoto with IS @ 1K mark, EF-S 55-250mm IS seems to be the only choice. If you want an all rounder, Sigma 18-200mm OS can be considered. They are all decent.

Softness is being very subjective. If you're comparing to a 70-200mm f/4L IS with every other telephoto lens, you will find them all soft. But it's fine if to get what you like.

p.s. Sigma 18-200 OS isn't very soft compared to 55-250 IS.

You can remove the grip anytime you want but the battery grip needs to be tight and contacts must not be contaminated with dirt or smudge. The dents are very normal.

My 40D had lockups several times. Beep but no reaction when shutter is pressed. Usually occur due to bad contact to lens. Remount lens and fully restart the camera by removing the battery.

Something is not really right if your other points are not producing sharp AF. I find all points on my 40D to be as precise as each other.

Canon, delighting you always. Have any grudge? Think Canon, problem solved.

I have also sent my daily lens and camera for calibration. When it came back, all points are sharper than before.

No. You are confined to camera's resolution. You need Canon 1Ds Mark III for banner and billboard use.
