How do I set 1/50 sec for 1080 50i? at DVinfo.net

I own a 2 year old EX1, firmware hase been updated to v1.20, everyting works fine, but I have a question. I shoot PAL 1080 50i. According to Doug Jensen's DVD, I should set my shutter speed to 1/50 sec. for best results, but looking at the shutter speed selections that I have available, for 1080 50i the slowest speed is 1/60 sec. When set to 1080 25p, shutter speeds down to 1/33 sec. are available.

Is the shutter speed setting, when on interlaced, the speed per frame or per field?

How do I set my shutter speed to be 1/50 sec. when I am shooting 1080 50i? Does a shutter angle of 180 give me this figure? Any enlightenment on this topic would be greatly appreciated, thank you.

Hi Harro,

For 1/50th shutter speed in 50i, just turn the shutter off. I'm sorry if that was not made clear in my DVD.
Same thing goes for 60i. If you want a shutter speed of 1/60th, just turn the shutter off.
