has a focus test chart meant to be used with a tripod (as all focus tests are) and he explains how to use it. Once your focus is verified (probably only need to do 70/130/200) at f4, go shoot a brick wall or something flat and check for focus and sharpness center and all four corners.

Once you've verified sharpness and focus, just go out and shoot, shoot, shoot. Remember to keep you shutter speed up. Until you've practiced, I would keep shutter speed at 1/400 or higher while handheld to help reduce blur caused by any shaking. Remember that DOF is increased as the f stop number is increased in number so it is easier to produce a sharp, in focus shot at f11 than at f4.

My recommendation...

1. Take the lens out of the box

2. Mount the lens on the camera

3. Take some pictures

4. Download the pictures

5. Look at the pictures

Lots of people take this whole business too seriously. It won't take you long to find out whether the lens is working correctly. My EF 70-200 F/4L is a great lens that I enjoy using to take pictures.

I just bought one also, used off of eBay. Here is a sample gallery from my first time out. I posted these images actual size to display the quality of the lens. The still shots are unreal. The "bird flying" shots are not, obviously photographer inexperience... I also posted 2 pics of a road sign at 200mm, one f4 another f10, to get an impression of the sharpness of my lens. Chek out the red duck's face in paricular to see what this lens is capable of. Comments please:

ChrisDM's Red Duck is a very good image to show off this lens. It was shot at f/4 and the eye of the duck is very sharp but the back of the head and bill are quite fuzzy. The point is that a long focal length and wide aperture will require the photographer to use great care in placement of the small zone of sharp focus. Here the photographer did well and so did the lens. If using autofocus, it is really necessary to be careful where we place that focus spot. When testing the lens, you are also testing your ability to use the lens. Be sure not to blame poor sharpness on the glass unless you have done everything possible to rule out user error.

After 40+ years of shooting - I find that the "Wildman" approach works much better than ANY forum. I'm going out to shoot now -
