Hi Bob,
I can't get the hang of not having a threaded view, but I think I'm responding to your comment about traveling light with the 30mm macro.....
I'd been using the 16/2.8, 27WR and 60 as a very light, multi-night hiking kit in recent years, and when the 30mm became available, I tried just taking the 16/2.8 and the 30mm.... a minimalist kit with macro in two lenses. I wasn't sure if I'd still prefer the 27mm FL, but found that the 30mm works for me.
I've found the 30mm a fine standard with close focusing - for me at least. Its working distances do get a bit too short as magnification increases - it's better somewhere south of 1:1. For day hikes when I'm not carrying a heavy load, I think I'll still add the 60mm.
Enjoy your trip.
Regards, Rod
