Originally posted by moodlover I am shooting mostly vertical portraits with the 105mm at f/2.4 and it's quite difficult to snap the eyes into focus when there isn't a bright catchlight in the eye or the subject is a bit further away. I also like to take real close-up portraits with it. I am wondering if anyone has any tips or tricks on landing the focus wide open right on the eyes of a subject while holding the camera vertically. I was looking into the Pentax 67 magnifier that flips on and off but read that only zooms in on the center? I don't put the eyes on the center so this is a big issue...
You're going to have to use some form of hyperfocal focusing to create an in focus zone for what you want to be sharp.
This would be easier if you had the 67ii, which has a slew of user changeable focusing screens to make life easier.
