I bought a pair of the swarovski 8*32 binos and a friend bought a pair of the 10*42 Pentax DCF WP. There may be some lowlight difference, but I can not tell. I know there is not $300 worth of difference. I would look hard at the pentax.
The Pentax cost $309 at AAACAMERA.COM. IF you fid you like them and want to look at a reconditioned pair, call Pentax service departmetn and see if they sell used/refirbished binos.
