This is what happens when you let your D40 go for a swim in the Pacific Ocean...cack everywhere, buttons jammed with sand and inoperable, small seaborne animals milling around the mirror box, and a completely dead body...deader than a run-over dead thing with no breath....

So today's swimming lesson is this - if you have to paddle in the sea, wear your camera around your neck, not slung over your shoulder where it could fall off...into the waves...to be ruined...along with the lens...that lovely 10-20mm Sigma (sob!)
