100-400 In Alaska

Jim, are you flying or cruising to Alaska? I haven't been there in a while. Wild place.

I see your point about the size/weight of the 100-400 compared with the 75-300. Both 4X zooms. One, 25% more reach, slighter brighter on the long end.

250% bigger and heavier. Seems like it doesn't have to be that much bigger and heavier. I'm not an optical engineer, can't offer any explanation. The Panny and the Sigma are too. The OLY is a better build quality than the Panny IMO, also the opinion of a Panny owner who brought his Panny when I borrowed the OLY. And he loved the way you can use the MC14 and MC20 with the OLY.
