[QUOTE="480sparky, post: 442536, member: 15805"] If your camera's sensor measures 6.4 x 4.8 mm, then take a ruler and draw a 6.4 x 4.8 mm rectangle on a piece of paper. Can you get that rectangle to fill the frame? If so, then you're shooting at 1:1, or 1x. Or if you have a ruler / tape measure with divisions at every 1mm, can you get close enough to image just 6+ mm? Same result.... you're at 1:1. But I think you're getting stuck on the math. Yeah, it might be nice to know, but it's certainly [I]not a requirement[/I] to either know, or post, the magnification. [/QUOTE]
