Hi, Most brands make a 50 mm lens and a 60 mm. lens with f/2.8 or f/4 that can be used as a normal lens. The question I would like to ask is, is it an advantage to take a 60 mm. over a 50 mm.? I would use the 60 mm., as if it were a 50 mm. lens. For example, to shoot a video scene from a distance of three to four meters, where two people engage in a dialogue, one could use either lens; but perhaps for close up shooting one can only use the 60 mm. lens because it allows to get closer than with a regular 50 mm. lens. If you were me, would you rather have or get a 50, or a 60 mm. macro lens? Thank you, kind regards, igmolinav : ) !!!
