The adapter will multiply the focal length of the lens you put it on by 0.2. The 1st post has it backwards, a larger number does not increase the effect, just the opposite.<br><b>References : </b><br> put the X on the other side… x 0.2, and put your lens in front of it.. 18mm x0.2, and your answer is 3.6mm.

Just like a 500mm telephoto lens can be called a 10x lens, making things 10x larger than a standard 50mm lens, a 0.2x lens will give you 0.2x the lens it's on....on a 50mm lens it is the equivalent to a 10mm lens. The lens attachment on a short zoom will give you an extreme wide angle to fisheye zoom which makes it much more useful than a fixed fisheye (look at the customer pictures).<br><b>References : </b><br> It’s the magnification factor.

.20x means it has that much fisheye distortion

.40x or .42x would have more fisheye distortion than the .20x
