Hi there OL....ya really wanna give the Canon 15x50 a try. That'll give any other 15x a run for the $, plus ya get IS, which can really be a boon if ya don't wanna use some type of support. I've had one for almost 8yrs and haven't yet found anything appreciably better. I've had one look thru a 15x60 Zeiss, and while that was very satisfying, it's a big, heavy, rather clumsy glass, and has IF (which makes it weatherproof, but not very versatile). Also did about a 30 min comparo with a Swaro 15x56 on a birding trip, and found it gives up virtually nothing optically (I never used the IS while A-B-ing, as the big Canon is the easiest hipower bino to hold reasonably still of any I've tried, which is about all of them), plus having the IS. The Swaro is a tad brighter, but for resolution, fov, er, a dead heat....except the Canon costs half what either the Zeiss or Swaro cost.
