Seems like Panasonic made a bit of a mess. First they made a teaser for the Jan 31 announcement but in very last-minute they decided to postpone it for a few hours. We have been told the official Panasonic S announcement will happen at tomorrow (February 1st) 11:00am London time.
You can join the new L Full Frame Facebook group if you plan to buy this camera. There you can discuss all features and tests once it’s released!
