I've posted before about a similar topic, however... Has anyone tried the new 18-135mm f/3.5-5.6 digital lens? All descriptions list that it's compatible with digital AF mount cameras, but don't say if the lens itself is an autofocus lens. Is it manual only? The product picture only shows the zoom lock switch, and no AF/M focus switch. It looks like a great all-in-one lens, and I'd love to know more. Anybody? thanks.
