Yongnuo 50mm f/1.8 review by Marc Alhadeff: “excellent performance”


Today the new Yongnuo 50mm f/1.8 E-mount lens is starting to ship out on Amazon and BHphoto.

Marc Alhadeff from SonyAlphaBlog tested the lens and concluded:

The Yongnuo 50mm F1.8S DA DSM (120 euros) is a very pleasant surprise : A Chinese lens with AF with very good to excellent performance in photo
In photo it is far better than the Sony E 50mm F1.8 OSS (280 euros)
The only drawback is in video with a capricious AF in this mode
Highly recommended for A6000 users if you are on a budget
For high end APS users having a A6500 / A6600 you may want to invest in the Sigma 56mm F1.4 DC DN (430 euros !) that is a bit better (but not 4 times better)

Very good to excellent sharpness
Very soft background blur
Very good color rendition
Good AF
Lens with electronics contacts so EXIF available and control of the aperture via the body
Cheap (120 euros)
Light and small

Bokeh balls showing heptagon when closed down to F2.8 or more
Chromatic Aberrations wide open when facing the sun
Build quality is OK
Moderate distorsion and vignetting
No Optical stabilisation

unreliable AF in video with V4 firmware (could be corrected in a future firmware)
