According to SAR, Samyang might soon announce a new 16-35mm FE lens. It is wide-angle zoom and more affordable lens for E-mount.
This new lens will be much cheaper than the current Sony FE 16-35mm F2.8 GM II lens.
It seems that Samyang may announce a third zoom lens following Samyang 24-70mm F2.8 FE and Samyang 35-150mm F2.8 FE lens. Sony FE 16-35mm F2.8 GM II lens is highly rated but is expensive, so if Samyang releases a cheaper zoom lens, the range of wide-angle zoom options will expand.
