Here is how it works, the sensors within your camera communicates with your lens to pick up contrast and light level but mainly contrast. This also applies to , too, when a specific part of your subject needs to be in focus. The narrow depth of field in these shots mean that you need to be incredibly precise with focusing and being just a smidgeon out or having your camera choose to focus on the wrong part of your subject can completely ruin a shot. So there is a tradeoff: while they might be able to focus more critically on distant objects which are also more likely to be in focus anyway due to depth of field , they have more difficulty focusing on and composing close objects due to parallax the viewfinder and lens see the scene from a different angles. I ran into him sitting in a bar having a drink -- but he had his camera with him, and picked it up, focused, and shot at least once every couple of minutes.

Any suggestions would be much appreciated. It reminds us of the good-old days when all photographers used to use only manual focusing thats all they had. One way to overcome this is to switch to manual focusing and prefocus on a point that the subject will move through — and shooting at that point. If you do this in conjunction with a large aperture which decreases depth of field and get in close to the fence or glass, you might well eliminate it completely from being noticeable in your shot.
