who keeps saying uncoated lenses are softer? Not in my experience -- coating allows more light to get through, but it doesn't improve the way the lens is designed ... a very old uncoated lens is perfectly capable of excellent results.

The thing you do want to watch out for is light hitting the front element -- they can flare a titch more, so get that lens hood. Shooting into the sun is asking for more trouble because more light bounces around inside the lens on those uncoated surfaces instead of passing through.

Some feel this bouncing lightens shadow areas a bit, making for a less contrasty look, but certainly not less sharp. Lens coatings are like every other aspect of photography -- a good image is 5 percent equipment and 95 percent the photographer.
