Honestly I can't see enough difference to make any real calculated conclusion. But I will say that I was more interested in how these lenses performed at 2.8 in sharpness across the frame. The Biogon-C is almost faultless at f/2.8, exhibiting biting contrast and sharpness wide open with a nice flat field, and I feel it's a challenge for any lens to beat that.
