Years ago, I was taught that the 100mm lens was the best portrait instrument. Now, it seems, this 1.2 seems to be accepted as the lens for faces, softening the background. Well.... which is it? 100 or 50? I am assuming a full frame configuration.... Would not my 100 f2.8 do great for portraits?
And please, no snarky replies. It is really unnecessary to be superior.
Your 100/2.8 is great for portraits, mine is, but so is a 50/1.2 —Different tastes.
