How water tight?

Just watching Survival with Ray Mears.

Impressive to see him photographing bears in torrential rain without anything over the camera and lens.

The video cameras are inside plastic rain shrouds.

His camera and 400mm f/2.8 are dripping and saturated. Still working as he's shooting away regularly as a bear goes by.

What an advert for weather sealing!

If it only was a Pentax

I am sure the Pentax weatherproof kit will do the same. Just need some one to actually go out in a torrential down pour to do the acid test?

I have the same body he was using but not the "vitamins" to take it out into a heavy down pour. I am still putting the pennies aside to buy either the 300 or 400 f/2.8

As well as more Pentax kit of course.

Been out in pouring rain several times... Rain harder than what comes out form the shower in the house. So that is no problem... I'd be more afraid of getting close enough to the bears to photograph them well.
I personally think 400mm is still a bit too close, but Pentax only has what, maybe 250mm or 300mm water resistant and certainly not in f2.8. Yeah, I might pass on that one.

On proximity to bears I agree.

I have used a 400 f/2.8 for a week or so. It is a unique piece of kit that demands correct usage. Pulling power and IQ were superb.

I am erring on the 300+TC combo due to cost of the 400. I have the TC so just need a green light from the wife to bring home a 300.

It must be nice to be in a position where it doesn't matter if you wreck the gear provided you get the shot.

As to the bears - no problem, we have a house full of them.
