Yeah i try to think about what lens to have in advance for the situation.
the FA 50 is one of my fav portrait lenses, but if its outdoors activities I'll probably take the 90mm instead.
Unless its for landscapes obviously. I have actually taken most of my landscapes with the 50mm, however i have a 35 as well, if its something that needs to be taken in one shot.
I'm looking to at a sigma 10-20mm soon.
I really don't like the quality from super zooms. I've also found i tend to use zooms all the way in or all the way out so decided i can replace them with two lenses in the end (maybe 3)
