I want to do some beauty portraits. Some of my shots will be from waist up, some of them will be tighter. For example just the face and nothing else in the frame OR a little going back to get the model from chest up to the head and some room on the other side of the picture for a brand name for example for the watch she is wearing on her wrist.
My question is about the Macro lenses and in particular this lens that I am thinking to rent:
The Pentax SMC D FA 645 90mm f/2.8 ED AW SR Macro Short Tele Macro. With a focal length equivalent to 71mm after sensor crop factor, the 90mm f/2.8 gives you macro lens that’s capable of 1:2 reproduction.
Is 71mm focal length too short for use cases that I am doing to shoot all of them with that? and is being Macro change anything? I mean although it is 71mm but because it is Macro does it mean still I can use it for tight portrait and fill the frame shots too?
I can also rent their 150mm lens which with crop factor is close to 112mm on 35mm, so which lens do you recommend for which use case that I have?
