My good old never let you down Zenith EM
Dont know if you'd call it retro though
I was up some hill or other in winter ,a good thousand feet up,plenty of white and damn cold, -18c or something
My mate brought his all singing all dancing grands worth of nikon with its laudy da motor wind
.Due to the low temperature his refused to work,seems the batteries had frozen solid
The Russian made zenith ,despite its bad rep for cheapness,worked flawlessly and produced its usual quality shots
I took it sailing and the salt got into its workings
Though im pretty sure it if i plunged it into fresh water and put in in a really hot room ,it would work again
Not retro but damned rugged
