This is the Canon 10-22mm EF-S 3.5 USM wide-angle lens with a Sunpak 77mm circular polarizer, only used for 2 and a half months.  [url=http://stormhighway.com/1022/]Please see photos here[/url].  I purchased this lens primarily to use on an aerial photo session via helicopter over downtown St. Louis.  You can see the results of that here:

<P>
I am selling the lens since I have finished capturing the photos I needed it for.  I purchased both the lens and polarizer brand new on September 15, 2011 from Creve Coeur Camera in O'Fallon, Illinois. 
<P>
The lens is in perfect condition with no scratches or scuffs. It has never been dropped.  Included are:
<ul>
<li> the front and back lens covers
<li> the case for the polarizer
<li> the original box and packaging
<li> the original purchase receipt dated 9/15/11
</ul>
I have to sell the polarizer together with the lens since it doesn't fit any other lenses or cameras I have.
<P>
$700 shipped (via FedEx ground & insured) for both the lens and polarizer to verified USA addresses.  Payment must arrive and clear before the lens is shipped.
