Yongnuo still has to fully unveil the pricing and shipment date for the new 16mmf /1.8 autofocus E-mount lens. But Marc Alhadeff was able to post the world’s first review of this lens and concluded:

The Yongnuo 16mm F1.8 DA DSM is an excellent wide angle lens for APSC. It offers similar if not better performance than the Sigma 16mm F1.4 DC DN Contemporary (APS-C) (420 euros) with the size and weight of the Sony E 15mm F1.4 G (850 euros)
Results are very good : very good to excellent sharpness, very good color rendition, bokeh , AF, good ergonomics, resistance to flare and low level of CA
The only drawbacks are the distortion and vignetting (that can be corrected automatically with a tweak in Lightroom) and some stab issue in video on A6600 (to be corrected in a future firmware)
At the time of this article , price was not yet fixed if below 250$ if will be a very good price, if below 150$ it will be a fantastic bargain

Highly recommended
