Long time ago trusted sources told me that Panasonic had the plan to upgrade the current Panasonic 7-14mm f/4.0 lens. The day may be close that this will happen because the lens just got discontinued at BHphoto (Click here to check). And only a bunch of them are in Stock at Amazon (Click here to check). The trusted sources told me Panasonic developed a OIS (lens stabilized) version of the lens.
Let’s see if the rumored May 21th announcement turns out to be real (reminder, this is a rumor coming form external websites!).
