The only circumstance I can think of where turning the dial makes no difference is if a lens is fitted with no electronic contacts, or an A lens or later is fitted and the aperture ring is not set to A.

Both were excellent lenses, but I bought the 28-105mm. There were three reasons for the choice - cost, bulk and the slightly longer reach of the 28-105mm. Although the 24-70mm might be slightly better in some ways, in practice it doesn't make much difference.

If all else fails, contact JPS for advice as a repair may be needed.

That should be it.

Also, try a rubber mat, placing the filter face down onto it. It grips, enabling better leverage when removing the other part, and also avoids the distorting effect.
Otherwise, don't fit filters tightly.
