Yap. They rent cameras to people.
During my buddy's wedding last month, he rented a Canon IXUS from Rentixus. I was actually their "unofficial" photographer. ;-)
The cam was pretty user friendly. I caught about hundred shots for the couple's dinner. Heard that Rentixus later sent them a CD of the images and my buddy's wife was pretty pleased with my shots. hahaha......
I think this rental thingy is good for ppl without digicams and don't want the problems with processing/download the images. Cheap deal compare to engaging professionals photograhers.
