Every year I try to upgrade some part of my kit from "cheap but good enough to get by with" to "hey this is pretty slick"
For example, over the years I've upgraded:
My light meter from an "iffy" swap meet Adams to a Luna Pro SBC.
My focusing loupe went from a uiquitous Agfa to a tilting Silvestri
Assorted cable releases of disreputable ancestry to professional grade Gepes
A motley collection of worn out gear bags replaced with a pair of Mil-spec surplus coyote tan 5 gallon water can coolers for toting film holders
A downright bizarre grain focuser to a Bestwell
Little by little my kit has gotten better, or at least better functioning. I'm thinking this practice has served me well over the years. As I'm contemplating what, if anything to upgrade this year I was wondering if anyone here does the same sort of yearly thing? If so, what bit of your kit are you planning on upgrading?
