Butch Cassidy, rklepper, butterfly2937 and davo1979 - Thanks for your input about Storm Jacket. It's definitely one I am considering.
jhom and alduin - Thanks for your responses. I'm not familiar with Think Tank but will check it out.
jon and PacAce - Right now, the Kata seems to be the front runner in my mind. Have seen a couple of friends use these in the field. I liked their design. Both friend seem to be satisfied with theirs. I understand that I would definitely need the sleeve for longer lenses. Thanks for your help.
Wilt - I understand the rain poncho to keep you dry but not sure how that works to keep the camera and lens dry. Care to elaborate?
Thanks everybody for your help.
John
