I have a Letus Extreem. I want to film a conversation real close and sharp with dof . My question is I have been using a 85mm and 100mm and 105mm. I never realy got a chance to fully explore the 100 and 105 but over all these lenses which would you say is worth me getting it. I also want to chase people in my war movie up close for action effect and all but am lost which one to buy. Thank you for all the help provided.
