Loving your photos...sorry I am just now catching up with this thread. I now have a better organized photographic tool bag situation.
I currently have all my Nikon gear in an old Domke backpack and a Nikon shoulder bag. The Leicas are now housed in three bags: the Billingham for when I want to take "everything" or just the rangefinders; the 5XB Rugged Wear for the X1; and a black 5XB for the R4. Now I don't have to unpack, repack, shuffle, forget, utter an oath or two, or anything...just get the bag for the task and go! Still got to get a dedicated bag for the Ciroflex, though.
The X1 may need a digital partner like the D-Lux 6. I am wondering about selling the IIIf and a couple of other things to get one as the images are terrific, and, the zoom lens covers most everything else that the X1 does not.
What do you think? A super-lightweight digital kit in a 5XB Rugged Wear bag?
