Does anyone know how are you have to be from a person to shoot 85mm and get the whole body in the shot?
85mm F1.4(8 posts) (4 voices)
On an FX Cam, if the person is about 1.80m high and you shot right-angeled to the person I guess it's about 3,5m
correct me if I am wrong
On an DX Cam about 5 meters ...
... again please correct me if I'am wrong ;)
Welcome to the forum, both of you. I get this for a person with 1.8m height:
FX portrait (image height 36mm): 4.2m
FX landscape and DX portrait (image height 24mm): 6.3m
DX landscape (image height 16mm): 9.5m
I was using something that will be pretty close for everything except for macro work:
sensor to object distance = focal length * (object height / image height)
If anyone wants to do it more carefully, you can use
1/f = 1/p +1/q
image height/object height = -q/p
where q = lens to object distance, p = lens to sensor distance, and f = focal length
or just wing it!
so you are saying i need about 12 ft or so from camera to person in FX format?
or just wing it!
Always so practical, shivas. Are you an engineer? ;-)
Kamerad, 12 ft would be where they would fill the frame edge to edge for FX, so you'd probably want to back up a bit from there. Shivas is right; you should probably just plan on walking a little closer/further away until you get the framing you want. But let's pretend you were trying to figure out if you'd have enough space in a place you were planning a photo shoot.
LOL, hardly - and you know, this is why I had a tough time getting my PhD when sometimes I would JUST wing it!
I'm a geneticist who ended up in pharma, where the winging it opportunity has some advantages. . . .
