I was out in this, not just near shelter but in the middle of the lake in a rowing boat. The white streaks are hail - what else in August?
Since I didn't think it was a good place to be in a thunderstorm, waving a carbon fibre fly rod around and having no waterproofs I rowed to the shore. tied up and grabbed this shot on my Panasonic G1 on the way back to the car.
The G1 immediately packed up but was working again this morning and I found this one shot had been saved.
Perhaps it doesn't look much in the picture but it was nearly 20mm rain in under 30 minutes and I was as wet as if I had fallen in.
Sooner I take the plunge and invest in an Olympus OM-D the better.
