Query: Pentax PF-63 Zoom

Purchased the PF-63 spotting scope from Pentax as a backup unit, at the price of $329.00, it seemed like a great deal. I must say I am very impressed with the spotting scope as a whole. Unlike a previous review, I have no problems focusing at any level, and the picture is crisp and clear from edge to edge. I carry a Swarovski as my main unit, but for a spare that fits easily in a backpack, you cannot go wrong with this little gem from Pentax.
