the face of the lady in the top left appears to be distorted, but the Biogon is famous for its lack of distortion. So where does the distortion come from?
The camera is not square to the scene (ie straight up). It's tilted down. The dude on the upper right is distorted, too. My bad. The lens is great for portraits, if you do your part.
It's very good for candids, but you do need to stuff it in there, squared up. I was only a few feet away.
Lucky for me, all of these subjects are drunk or distracted.
Damn always wanted one, I fondled with a 903 a couple of times over the years when Aperture in London had one. The closest I got to that lens was the ZM 21/4.5 C.
