I have a new version of the tri-elmar lens and it is used mainly for landscapes when I travel. I do also have the 35, 50 and 90 mm prime lenses for when I want to have the speed. The whole kit fits into a nice small bag, so I can take it all or just one or two lenses. The lens that I would like to have is the 24, but it's outside of my price range at the moment.
