Wil this work on a sigma 58mm 70-300 lens?

I've used the graduated filter up to a 62mm diameter lens. You probably couldn't use it on anything much bigger as the adapter ring I had for 62mm seemed to be almost the same size as the filter holder. I love the graduated filters because they can really help balance out dificult lighting situations. You can expose more for the shadows without blowing out the highlights.
