>>199540 If you know of another objective measure of lens resolution and contrast, let's see numbers in that system. Everything I've heard, seen, and experienced says that the 1.8 is sharper than the 1.4 at similar apertures, and kicks its ass at f/4-f/11. From a theoretical optics standpoint alone, making a 1.4 lens as sharp as a 1.8 is going to be difficult and likely require ED glass, a fluorite element, and/or an aspheric element.
