Disclaimer: I can't quantify this and I don't intend to start a heated discussion over best, or over-rates lenses. Also acknowledge that most has to do with the photographer than equipment, but... I've noticed that some lenses seem to have a quality beyond color and sharpness. Something about them makes a subject stand out in a way that isn't just sharp, isn't just background blur. Some have referred to it as a 3D quality. I don't know what it is or how to describe it, but I've seen it in images here. Is it real, is it just a particular pic in special light that any lens would have created, or do some lenses really produce it more commonly than others. What do you think?
