I found a use for a Canikon macro zoom lens! It makes a smashing vessel for my tea. Seriously though, thank you Vanessa and Owen for this smashing Christmas gift. A novelty drinking flask cunningly disguised as a Canon zoom lens. Nice one.
EDIT: Today I learn’t how to clean an in situ focusing screen on an old Pentax ME Super without too much damage. Yesterday I learn’t how to totally foul a focusing screen up while changing an SLR mirror pad. It’s all about learning in this pastime.
