Hi
for 35mm it is recommended to use at least 85mm or even 135mm for portrait due to compression effect prefered to a wide angle.
On the other hand 50mm is seen as "normal" while around 80mm would be "normal" in MF.
How is the 80mm effect resulting in an MF compared to a 50mm in 35mm?
Does it just show the same frame or does it also give the same effect?
Is it as fine to do a close up portrait with a 80mm on a hasselblad like doing it with 80mm on a 35mm?
Or would this result in longer nose and so on as the 50mm?
best regards
You are treading on very dangerous sands; the risk of being sucked down into the Underworld is great, so beware what you ask!
Your question is basically about the effect of distance on the human face, and the main factor affecting that
is simply the distance between you the photographer, and the subject.
Whichever camera format you use it remains the same problem. You have first to decide the distance away from your subject that you feel gives the best look to him/her. Your eye should tell you that. Then you select the lens that allows you to fill the frame at that distance (assuming you are only interested in a head-shot). In my own case, I seldom wanted to work closer than about six feet from the model, so I used a 135mm lens on 35mm cameras or a 150mm on 6x6 cameras. On the latter, I would have preferred a 180mm, but though I had that with my old Mamiya TLR, I could only find a 150mm for the ‘blad when I graduated to it; the 180mm didn’t exist in the range at the time I was buying into the system.
(Specifically regarding your question, I wouldn't dream of doing a close-up of a face on a 500 series 'bad with an 80m lens if I wanted to remain friends with the subject afterwards.)
That’s the simple answer. Unfortunately, that leads to different problems as you go to noticeably larger camera formats, mainly because of the change in the depth of field that you’ll run into as you change the magnification of the image on screen.
