YONGNUO YN25mm F1.7M Autofocus Standard Prime Lens for Micro Four Thirds Mount,Compatible with Olympus Panasonic Cameras

Had low expectations but really impressed with this lens. Works perfectly with my Panasonic GX85 and the sharpness and general image quality is as good as my other Olympus and Panasonic lenses. Has a little softness at the widest aperture but for the price it's fantastic.

Bought on a whim due to the cheap price and it has exceeded my expectations. Well built and works flawlessly with my tiny Olympus PEN E-P5L, 25mm on the M4/3 sensor with it's x2 crop factor makes for a great wide aperture 50mm equivalent and a handy little street shooting setup. It even has surprisingly nice out of focus bokeh too. Only down side, no native lens hood, but its seems to handle flaring quite well too so it's not a deal breaker. All in all a surprisingly good little lens, especially after having a less than stellar experience with some cheap Yongnuo DSLR lenses in the past.

For the price this is an excellent lens - it works perfectly with my Lumix g100d - between f2.8 and f8 the image is acceptably sharp - the lens feels well made and attaches to the m4/3 mount firmly - the autofocus is good for still photography though for video there is sometimes a degree of 'hunting' - all in all an good purchase with which I am very happy.

It’s cheap and cheerful, but surprisingly decent. Certainly a good alternative to the overpriced Panasonic option. Worked very well both in video and photo.

Very sharp lens, good value for money.

Nice and light, good in low light.
