Lenses for Canada/Alaska

I've synthesised all the replies and there is support for 7-14 (or 9-18) and 50-200 and considerable grounds for not changing lenses too often.

There was a general trend towards leaving the 14-54 behind. This fits with the claim that zooms tend to be used most at their extremes.

I will work on the 2-lens basis (+XZ-1 which, of course, does offer the same range as the 14-54 - albeit at slightly lower quality).

I will take 2 bodies. They are both quite old now and failure of either can be compensated, while failure of one 510, if it is the only one carried, obviously cannot.

Thanks again to all.
