Now if you upgrade to the "pro" style of lenses they have a constat Aperature of f/2.8, or f/4. You can use that Aperature at any focal length. Here's an example 70-200mm f/2.8. Hope that helps.

Now does that mean that you are stuck to using an apperature of 2.8 at any zoom or that you have the ability to have it that low? I shot 5 cars at work today and no alas on any DOF only on closeup shots of lights and nametags, for shots of the whole car, it doesnt work. TROLL is it ok to post 4 or 5 pictures here to show what i mean or should I make a quick thread. They are all resized to 640x480
