Samyang, also known as Rokinon or Bower depending on the retailer, has posted a teaser on its Facebook page for two upcoming lenses — a full-frame lens and an APS-C lens — which appear to have been designed specifically with astrophotography in mind.

Samyang doesn’t reveal the focal length or aperture for either lens, nor whether these are manual lenses or autofocus lenses, but both lenses are relatively compact primes based on their respective silhouettes. Samyang says the lenses will be ‘Masterpiece[s] for Astrophotography,’ with night sky photos (presumably captured with the respective lenses) as the background for the teaser.

The duo will be out by the end of the month, according to the post, so it shouldn’t be long before we know the details.
