Sometime you got THIS moment, and your equipment is somwhere else. Or you have the wrong lens on your camerabody. Often I see cool animals next to me and its difficult to get a closer look of them. Than I move slowly, pick out my pocket my mobilephone and press the volume button twice. After a few secons I have my camera started and I can shot pictures or videos of some cool situations or animals. I’m glad to have such a macro lens on my actual smatphone (LG G5).
