Otis wishes you well and commends you for choosing the K5, a fantastic camera! He does disagree on the lens selection, thinking you might like the Bigma 50 or 150-500 better than those little tiny lenses that won't reach out for a Handsome Squirrel. I do see your point, and it could also be that Otis is somewhat biased toward Squirrel shots.....
Whatever lens you get, I hope it delights you and fulfills your expectations...as for the K5, I am already certain it will surpass your dreams of a dream camera.
Best Regards!
