As usual, surfing around the web and youtube gets me into more questions that it answers. I saw a number of videos by different people, presumably pro photographers and they all say different things. Some say that no lens of less than 100mm makes good portraits, while others sing the praises of the 50mm with FF cameras. What gives? One particularly interesting argument against shorter focal lengths was that even with M43 and other smaller than FF sensors, the focal length is the same as the 35mm equivalent because all we have a crop factor and the barrel distortion still exists... Anyway, the subject isolation (DOF?), excellent bokeh and no distortion that one can get with FF cameras seems to be out of the reach of M43 cameras because of these factors... To make matters worse, since we are using an effectively cropped area, we cannot even get the whole picture without having to stand twice as far from our subject as with the FF format cameras. Anyway, I don't pretend to know about these things and I don't mean to start some sort of polemic. But I would like to hear what the cognoscenti have to say on the subject. And of course, I want to know what lens to have for best results of head shots and portraits. Cheers!
