Originally posted by DirkG In most circumstances, this range is enough for travel, but occasionally going beyond 50mm might be interesting.
There are various solutions to this problem of augmenting a basic (15/17-50/70 APS-C) travel kit.
Sometimes I use Saxplayer's method, with the M100/2.8,
but on other occasions I've brought along a superzoom P&S,
which can also be handy for birds and beasts in good light.
I like the ones that use the same AAs (and charger) as my K-x.
Never bothered with teleconverters, though,
or a Q/Q10 and K2Q adapter to "stretch" the APS-C lenses.
