Paul asks…whats the highest and lowest mm for a digital camera?is 15mm the lowest and 200 the highest?mr.eos answers:That depends on the camera. If you have a digital SLR like a Canon EOS then the lowest (widest) is a 4.5mm lens http://www.bhphotovideo.com/c/product/535757-USA/Sigma_486_101_4_5mm_f_2_8_EX_DC.html
