My most recent wedding last weekend was the first time I added videography without bringing a videographer. The couple was already purchasing the slideshow montage and I wanted to experiment with video so I shot clips throughout the day. For the stills I used (along with my assistant)
Pentax k-7
Pentax k20d
Canon 5dmkII
Canon 1DmkIII
For video I used
Canon 5DmkII
Pentax k-7
Canon G12
The only thing that kinda sucked for me was that I had the k-7 mounted on a tripod shooting video of the ceremony... and my assistant was holding the 1D and the k20... so I only had one body during the ceremony. Not that it mattered because the ceremony is pretty easy to shoot anyway - and my assistant is awesome. But I felt naked with a single prime lens on a single body for that part of the day
The best part of my setup was carrying the p&s camera with HD video that I could give to other people to shoot for me. You can see the bridesmaid shooting the video of the "first look" in the still photo I have right after that clip.
The other thing that sucked about the day is having to put away both Pentax cameras after the sun went down. The k20 stopped firing the flash AT ALL... not in Manual Mode... not in p-ttl. And the k-7 was struggling to focus in the dark with the fast action... and it sucked past ISO 1600 so I could not get the ambient light I wanted. In the end I did all the night shots with the Canon's at ISO 6400 F1.4 (on 35mm and 85mm lenses... and using a VERY small amount of flash).
I have too many cameras and not enough money but I suppose I will need to pick up a k-5 sometime if I want to keep shooting Pentax
