Advice please.
I am going to buy a lens specifically for portrait use. It may also be used for video interviews at portrait distance.
It will be used on a Canon 5DIII (and possibly my son's 7D and 6D that I might buy for office use) and most of the output will be published on the web or in brochures converted to PDFs and sent electronically.
I am attracted to the idea of being able to achieve shallow depth of field: shallower than I can get now with my 24-105 f4 L. Low light capability is an advantage though we do have a powerful LED lighting set up use in our office (where many of the shots get taken). We usually use a tripod for stills and always for video.
I am not necessarily wedded to buying Canon, so Zeiss, Tamron or Sigma may also be suitable if they are optimal. Autofocus is nice but not essential. It must be sharp (I can always soften pp if needed).
And I have considered a macro lens (L or non L) but am aware that most of the focus adjustment on such lenses is at the macro end so may be troublesome on a lens used for portrait and macro? Or is that not really an issue. 100mm seems in the one for macro.
I am not especially price sensitive, though have no desire to waste money. I have zero experience with specialist portrait lenses. Review on the web help a little bit....
Is the 85mm L Canon f1.2 too limiting for example? Some people love it, some say focus is ever so slow and rather hit and miss.
Thanks in advance
