I'd be guessing that it's not all that waterproof.
What I used to do for my old film SLR's is put a second UV (or skylight, take your pick) filter on and tape a plastic bag over the entire camera, from the front filter back, so it was in a complete bag. Then you just have to wipe the filter occasionally. Makes the viewfinder a big vague, but keeps things dry as long as you're careful not to rip the bag. A decent lens hood will also keep the drops off the front filter.
If the end element on the lens rotates as you focus you might have to stick with manual focus as the load on the focusing motor might be a bit much.
I assume you're talking about light rain, not a tropical storm? My OM4 never complained about being a little wet, from drizzle etc, but I don't think I'd contemplate taking a dSLR out in the rain if it wasn't something like the 1d which has more seals than I've had hot meals.
Just my 2c worth, and of course I don't own any nikon gear (appart from a CP2500) so can't speak from experience, but I'd be taking a fair bit of care with an entry level dSLR in the wet, lots of electronics to make unhappy if it gets wet.... |
