"Clunky" as in onamatopaeic description of the camera's operating cycle,
or
"Clunky", as in not fashionable or stylish; awkward ? (Chunky shoes, clunky purse...)
My 1920's 3-1/4 x 4-1/4 RB Graflex fits both definitions ! 😀
My favorite 35mm SLR is still my 1955 Exakta VX II, followed by my Pentax SP-500... most of my film shooting is done with my Leica III and Leitz lenses, but I'm not even thinking about ditching my "clunky" SLRs... not even the Graflex ! 😉
