i just checked out the price of the Pentax 145mm clear (no effect) SMC protection filter for my A* 400/2.8. it's $519 from B&H. i never use a filter on my lenses unless i am using it's effect. it's another pair of lens surfaces to keep clean and, even though most of my filters are multicoated, more chances for flare. i use lens hoods.
