Hi everyone,
Thanks for everyone who is replying to all these threads.. hopefully I haven't "Alaska'd everyone out".
Oh question about lenses and filters etc. I brought WAY too much gear. For 99% of my shots I used either the Sigma 17-70 or a Tokina 400mm f/5.6 AT-X. I used a Tamron 70-300 for few shots buts thats all.
What I did bring that worked out VERY well was two camera bodies. I had the Sigma 17-70 attached to my Ds most of the time and the Tokina attached to my K10 (for the SR). I did switch for some shots at places I knew I wouldn't run into any wildlife. I didn't use any filters at all. I did bring a cheap tripod and a monopod, both worked out pretty well. I could have used a better tripod but I didn't want the extra weight (or spend the money on a CF one).
I mentioned this in the other reply.. if anyone is planning a trip let me know if I can answer any questions. We where there for almost a month so I could have some tips
