Panasonic 150mm f/2.8 mft lens is rumored to be released at Photokina show this year in September. The lens first displayed two years ago again at Photokina show.
Panasonic 150mm f/2.8 is a telephoto prime lens for micro four thirds cameras introduced back in 2012 along with the 42mm f/1.2 prime.
According to recent rumors, there was a slight problem with the production of the lens that Panasonic had to solve. That’s why it’s coming a bit later than expected.
