Beautiful glass that is sharp from open and has a surgical level of sharpness at f2. The colors are superb. HA on the open is, of course, but there's nothing particularly urgent about it. The autofocus is nice, but I didn't try it for the reportage; it's perfect for portraits; occasionally you'll miss the shot at 1.4, but if you take your time and make sure you're aiming correctly, everything should be fine. The artwork is open to interpretation, but I find it really appealing. Pros: Aperture, sharpness, pattern, and color reproduction are some of the components that make up optical quality. Cons: The weight and the price, which might not be a problem for some people, but you need to be aware that an optics plan of this nature cannot be both light and inexpensive.
