Is a very tough thing to define. I've been debating with some of you enthusiasts lately about the lack of character of some native lenses (namely the 45 and 75 primes, which are fantastic optics but look very sterile and lifeless to me). So I got this picture tonight from an old Canon FD 135/2.5 S.C. prime tele lens, and I think it illustrates perfectly what "character" can look like in a lens. I have not applied any vignetting in post to convey the real rendering of the lens. Very minimal PP (levels/WB type) to jpeg file. Here it goes : Some may or see or not see it. I'm open to all opinions, let me know what u think.
