Opteka will soon announce a new 28mm f/2.8 HD Multi-Coated E-mount Lens. Above you can see the first image.
6 elements in 5 groups
9 aperture blades
9.8” (0.25m) minimum focus distance
But there might be a chance that this is a re-branded version of the current Meike E-mount lens :(
Thanks Mistral for the Meike tip!
