There is a slight misunderstanding going on here regarding your request for a small front filter lens. The front filter is a good indication of the size of the beam of light coming in to your lens at maximum aperture. If you want a smaller aperture, stop your lens down. To determine the correct f-ratio that will give a 58mm size "hole", take your focal length divided by f-ratio and that's the true aperture. For instance 200mm/2.8=71mm aperture. 200mm/3.5=57mm. There's no reason to buy another lens unless your real reason is for a lighter lens.
Also, I assuming you know that to shoot between the chain link fence you need to be right at the fence - like touching it. You can't be back away from it. Also, you have to center the lens "between" the links. You'll see the links in the outside of the view finder, but when the picture is taken, the lens will be stopped down and they will be gone.
