the lower the number the more you can see. typically form 1-.5 it is wide angle. from .5-.4 is super wide angle and from .4-.3 is fisheye. not sure if you can get a fisheye with less then .3? oh and if anyone is interested im selling my .42 super wide angle. the thing is awsome but i dont have the cam anymore. 37mm threads
