Pretty sure this is all-time low for any stock (even grey import). I have it and it is a great do it all lens, arguably the best superzoom out there - sharp, fast. Only downsides are no OIS and 'limited' range compared to the (much worse optically) 24-240mm for example.
Part of the 20% off sale. Apparently there's rumors the store is closing down after Q1 on Whirlpool.
Great all around lens. Same size and weight as the Tamron 17-28mm 2.8f lens.
