I still use my lenses in the rain but am more cautious. If I have the 16-50 or 18-135 mounted when it starts raining I then use them as 16 and 18mm primes respectively.
I just won't trust the seals when there is positive or negative pressure building in the body.

No, I would not. The focus throw is so large that it will also pump air.Would you add the 100mm F2.8 macro WR to the "safe" list? The lens barrel does extend for focusing of course, but the rear glass element is fixed.

I would have thought the seals in the lens would be just as likely to suck in water as buttons on the body, if not more so, as the moving parts of the lens cannot be fully sealed. Because they are designed to move and slide against each other!
I tested this quite thoroughly, air gets pushed not though the o-rings in the lens but in and out of the mirror box.I would have thought the seals in the lens would be just as likely to suck in water as buttons on the body, if not more so, as the moving parts of the lens cannot be fully sealed.

I never had any issues at all using my K-7, DA* 16-50 or DA* 60-250 in very wet conditions. Sure zooms act as an air pump but they should be vented correctly through the body and I would be very surprised if Pentax hadn't thought of this.
I know my current gear (also weather and dust proof to a high standard) is vented in such a manner.
They apparently have not thought of it. Did the following test on both the K10D and K-5 with identical results.I never had any issues at all using my K-7, DA* 16-50 or DA* 60-250 in very wet conditions.

Mount 18-135 or 16-50.
Make sure all ports are closed and proceed to zoom the lens.
Air moved in and out of the d-pad ring and 'ok' button on the K10D and similarly positioned buttons on the K-5.
When the SD card bay was open the lenses zoomed much more freely as there was no pressure resistance on the seals and it really blew quite strongly out of the open door of both cameras.
If I have my cameras in the rain with a 'sealed' lens I will no longer zoom it. I will leave it on the shortest extension and dry it off well before zooming. Or ensure I have a non extending fixed volume lens.

Just a word of warning, the lenses are far better sealed than the sealed cameras. Do NOT use extending lenses in the rain! I have learned this the hard way. Extending the DA*16-50 or DA18-135 causes air, and if the body is wet, water to be drawn into the camera body via buttons, dials and covered ports.
The lenses themselves won't leak.
The only safe lenses for all weather are the DA* primes and the DA*50-135.

DA*300 vote here as well. Not a lens I use often but always gives very good results.

No, both those flashes would only work in fully manual mode. Better to got for a P-TTL model as it will get you going with automatic exposure but still let you expand into manual control.

I know their radio triggers are very good. Am quite tempted by their fully manual flashes as well. I don't know how good their P-TTL flashes are sadly.

Weight will be a problem but Having used similar ones in the past I didn't find it too bad.
Where did you get it and which size as I need 2 for my Metz 58s.

What diffuser is it?
As for falling, what flash is it mounted on?

Metz 50 or 58! Full P-TTL and the best manual control level of any flash 1/1 to 1/128 in 1/3rd stop increments for the 50 and up to 1/256 for the 58. Tilt and swivel, AF assist and much cheaper than Pentax versions.
The Pentax 360 has a poor reputation for the battery door lock breaking and cells falling out. Don't know if they ever fixed that design flaw.
I use 2 Metz 58 AF-1s as my on-camera flash units.
Having said that though I find that I am generally shooting with no flash or off camera flashes.
There is just so much you cannot do with the flash stuck on the camera.

I really like the Cactus V5 ( www.gadgetinfinity.com ) as they use standard batteries, have an insane range and last a long time.
