Yongnuo announces compatibility with the following models:
- Panasonic GF8, GF9, GX85, G95; G9 and GH5
- Olympus E-PL9, PEN-F, E-M5 MkII and E-M10 MkII
As is often the case with Yongnuo, the returns are mixed. We have here something correct for the price, but above all a new lens opportunity for Panasonic and Olympus owners, which is a good thing because Yongnuo for years has been focusing on Canon and Nikon models most of the time.
To finish, here are some promotional shots of this 42.5mm f/1.7 lens provided by Yongnuo. Unfortunately we don’t have the original files so we can’t zoom in on the details.
