Originally posted by pathdoc Without knowing exactly where you're going, my advice to you would be leave the fisheye home and probably the 40XS as well, and take the 18-55/50-200 combination. I know you must be really eager to shoot the fisheye since you've not long got it, but going away on a trip - especially if it's once in a lifetime or otherwise very special - with a lens you're not very familiar with could be a recipe for disappointment, especially if your photography is a secondary purpose or consideration on the trip.
It's a tough decision, since the 40 is so small and I'm loving it, it comes for sure.
The fisheye would be nice as I havn't used it yet really. 50-200 I'm not sure how much I'll use the long end in France.
Originally posted by pathdoc A more important consideration might be backup. If you're going to have any access to computers at all, you might want to take along a USB card reader and a couple of spare SD cards to put your day's pictures on. Also, how are you going to handle power requirements? I almost bought the K-30 instead of the K-5 because it could take AA batteries. if the K-50 does that, you're set; otherwise, you might be looking at squeezing a charger into your bag esp. if you're taking a lot of flash pics.
I'm going for a month so the charger will be a must. I've got the AA adapter and some AAs ready for emergenices, but I prefer using rechargeable batteries.
I believe we'll have a computer with us, but if not I have a couple spare cards, just there won't be any back ups.
