okay guys here goes.
for portraiture headshots the best theoractical focal length to use is between 85mm-135mm or somewhere around that range. this is the range where your headshots won't come out too flat or too long, and more or less "just the right size". okay basically this is not the main question..
the main question is..
if i want to achieve let's say 128mm (80 x 1.6). there're actually 2 ways of looking at it. that is i use an 80mm lens, and the focal length is multiplied to 128mm and the headshot lies within the range. (yes i'm being stubborn but pls, this is not the issue)
i use an 80mm lens, the picture actually comes out either too flat or too long, and the camera CROPS out part of the picture to make it SEEM like the picture was taken using a 128mm lens.
so my question is.. which is more correct ? that if i use an 80mm lens, the focal length is 128mm and i take a "proper" picture,
or that i use an 80mm lens, i take a "wrong" picture, and the camera CROPS the picture to make it look like it was taken with a 128mm lens ?
hope someone can help.. lol.. just occured to me. sorry. thanks.
