Nope...but maybe you should get one anyway just in case.
I get this question A LOT. Maybe it's because the sales people at the camera stores are talking them up as add-on sales or giving buyers one to sweeten the deal on a high end lens. I've had a few over the years and what I can tell you is that they do not make an ounce of difference when it comes to image quality. In fact, if you get one of low quality it may actually degrade your images.
Modern cameras simply do not need them owing to advancements in sensor and lens optics. All those wonderful coatings your lens manufacturer tells you about in the manuals but nobody ever really reads about...Like my Olympus ED 40-150mm F2.8 Pro telephoto zoom.
Blaahh Blaahh Blaahh
Personally I keep a set of UV filters in my gear chest for whenever I plan to be shooting in locations where there is blowing sand (think the beach), driving rain or water spray..again think the beach. I would much rather clean salt spray off a UV filter than the front element of my expensive lens.
I tend to shoot with a lens hood attached at all times, both for protection of the front element and to block stray light. UV filters can add an extra later of protection but I haven't experienced that in many years.
So to wrap up...buy one if you need a barrier between your lens and the elements, otherwise save your money.
