Does anyone have any pointers to a suitable wet weather cover for the V1 (not an underwater bag)?

B&H has a Petrol Cover (PRC-DV Rain Cover) that fits well. Lots of zips and adaptable pockets, collar for the view finder and shotgun mic, stud collar for a light, plus a clear envelope for the flip out screen and a brim over the sunshade. And I have tried it on my V1. I'm sure there'll be modifications in the future, but if I had to stake out in the rain today, or sit under a snowmaking machine tomorrow, I'd feel confident the camera was protected. Right now it comes as a package with a decent carry-on camera bag.

Thanks Martin, the Petrol cover Petrol PRC-1 seem s about the right size?

Greg, not that one. The PRC-DV is included in a package with the PCUB-1N/PRC-DV that is a B&H recommended accessory for the V1. The V1 is very similar in size to the PD170, so the PRC-1 is probably too big. I've checked the PRC-DV on my V1 and it seems fine.

Excellent, thanks Marcus.
