Yongnuo has released at the end of 2019 a first lens for owners of 4/3 Panasonic and Olympus micro cameras. It is a 42.5mm fixed focal length lens that opens to 1.7.

Its small price under $100 should please most people. The equivalent at Panasonic is the Lumix G 42.5mm F/1.7 OIS which costs around $350.

42.5mm on a micro 4/3 camera corresponds to a focal length of 85mm in 35mm equivalent.

Characteristic of the YN42.5mm F/1.7 Macro:

• Focal length: 42.5mm
• Structure: 8 groups / 9 elements
• Diaphragm: 7 slats
• Minimum opening: F/22
• Mount: 4/3 Panasonic and Olympus Microphone

Here are some official pictures of the YN42.5mm F/1.7:

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.

Fans of Panasonic and Olympus, tell us if you are interested in this lens, and why? How do you plan to use it?
