  2. Hi All, I'm a bit confused . When I'm looking for some additional lenses (both for above water and under). Some manufacturers quote a 16mm wide-angle lens, while others quote 0.5x magnification. How do I compare the two? Now this is my guess, someone please correct me here.... Ok, most cameras used to be 35mm. A bigger number meant getting closer or magnifying the object (ie telephoto or macro). A smaller number meant getting further away (ie wide angle/fisheye). Now, say you have a 35mm and you get a 16mm wide-angle lens, what is the magnification? Is it simply 16/35=0.457? If so, then I can just apply that to my digital camera and everything is solved For example, my digital camera has the 35mm equivalent of a 27-110 mm lens. So if I have a 0.45x WA then do I end up with a 12.5-49.5mm lens? So what does this mean? What is my view angle? Is it possible to calculate the viewing angle as well? Again, some people quote a size, while others quote view angle. Last, how do all these numbers change when you put the camera in water!!!!! Sorry for all the questions! Cheers, Adam L
