Some SUPER macro video of a cluster of baby freshwater ramshorn snails. I've been watching these eggs for a couple of weeks now. Four days ago they were completely transparent spheres with no apparent structure. Two days ago my camera could just barely make out a small dot in each egg. Today, I saw movement, so I grabbed the camera and to my amazement this is what I saw :)

Shot with a Canon T2i using it's 640x480 cropped video mode with a Pentax 50mm f1.7 lens reversed onto the standard Canon 18-55mm kit lens for macro. So a reversed 50mm on a 55mm lens on a 1.6 crop 18-megapixel camera and a video mode that gives roughly another 10x. I donno how much magnification that works out to but it's a LOT!
