Originally posted by robgski FWIW, the 40mm XS is always in my camera bag, it's my "go-to" lens when I just want to have a DSLR without all the bulk of another lens,
Sure, Rob, I'm always bemused by the 'what lenses should I take?' threads, since only we know our shooting styles.
Somebody each day going with me to the same locations is going to take different shots, unless we both lack imagination.
That 40mm fits in very well with a lot of possible combinations though - slightly long on APS-C, slightly wide on FF - and it's so small that you can take it as a de facto lens cap.
Bert's selection of it and the DA21 Limited means he's only carrying two pancakes - a nice setup.
