John, since I don't have the quickest eyes anymore... Well, let's be frank, I haven't been any good at manual focussing for anything besides flowers or a still life since about 1985, I'm big on auto focus, too.
These lenses do seem to hold a great deal of promise, however. Fingers crossed for all you "interchangeable" folks.
Wolfie, many thanks for this news flash and that link! Here is an excerpt:
Announced jointly by Olympus Imaging Corp. (President : Masaharu Okubo) and Panasonic Corporation in 2008, the Micro Four Thirds System standard has rapidly grown in popularity. Now, support for the standard is expanding with the decision of Carl Zeiss AG to join the Micro Four Thirds System standard, and the company is releasing lenses compliant with the standard.
