How do you know that the lens will fit on your digital camera?I currently have an s3 and want to purchase a 49mm CloseUp +10 / Macro Lens Filter.
How do I know which size filter to buy for my camera?
On the very front of the camera, it says 6.0-72.0mm...does that mean it could fit anywhere between 6-72mm size filter?

I can't say for sure...but I think 6mm to 72mm is your focal length.

Dr. Sam
The focal length does not have anything to do with your filter size.

You first need a Canon LAH-DC40 lens adapter to provide a 58mm thread to mount the filter on and then you can buy the close-up lens that you want.

PLEASE check with Canon or a dealer about the correct lens adapter number and configuration.

Easy way: Call the nearest dealer who sells your brand of camera and ask what filters will fit.

Hard way: Google for a review of your camera and scroll through the pages until you dig up something.
