Hi, I recently got a 1Ds mk3 after using my 5D for a few years (I will keep it). I also have the 1D mk2 but the better image quality of the 5D kept the 1Dmk2 as backup (used it for sports mainly when needed).

A few days ago I had to shoot on a film production set for 12-14 hours. The morning started nice, sunny morning on the beach. Then the weather turned sour. Started to rain. Even though the production crew kept a small tarp/tent on the motion picture camera at all times, it was leaking at times and sometimes I had to shoot outside it in the light rain. My camera and lens got wet constantly. I dried it off every chance I got but the rain/drizzle was constant. I used the 70-200mm f2.8L IS and the 17-40mm f4L. Both worked great. I dont know if the 5D would have been able to take that.

Didn't look at your images but I just shot an event in a heavy downpour with my 1D3 and a 24-70. Wouldn't have tried the same with a 5D or any other non-1-series body. Performed without a glitch. Only worry was a Quantum battery I had attached to my 580 II. As I'm posting, I survived so the Quantum did OK. I love the weather resistance of 1-series cameras....

This past winter I've spent 4 hours shooting a x-country ski race in extremely heavy wet snow using a 30D and 70-200 without any issues. Of course the 1 series can handle the extemes much better, but they are not full proof as has been documented on various occasions as 1 series dying during light rains. Best approach is to use a "rain jacket" on your outfit if the weather turns for the worse.

This spring I fell through ice at a lake (only at knee/thigh height). My 1Ds2 and 24L went below the surface for 2secs. The camera went nuts (shutter going non stop without pressing any button etc) and was showing Err 99 (whenever the LCD was even showing anything). The lens leaked out about a tea spoon amount of water in the car on the way back.

Fortunately, nothing was broken! The repair shop just cleaned contacts etc.

Its very important that the lens be sealed too. The new 70-200mmf2.8L IS and 17-40L I was using have the rubber seal at the lens mount. I could see water dripping down that area. Nothing got in.

I live in Oregon and have spent the last two years shooting winter and spring Lacrosse games in downpours to drizzles without the use of any additional waterproofing. I have used the 5D with the 100-400, 70-200, and 24-105. I am certain that I have shot atleast 50 days in mist to heavy rain and I have never had a more sever problem than drops on my UV filter. I have not dropped it in standing water, but the camera and my GoreTex clothing were all thoroughly soaked. I have also done the same abuse to this camera by hiking the Columbia Gorge on weekly winter hikes, and again no problems. I have just returned from a week in the Buckskin gulch and South Coyotte Buttes region of Utah and Az. The sand was everywhere, but again I have not had any problems. I am impress
