The pats hours I got some more additional info about the new lens and here are the specs we know:
- weight 1850g without hood and collar
- takes no teleconverter
- 105mm filter size
- White finish and similar look to the 300-600mm lens.
- super fast autofocus (according to sources)
- Full Frame
- For Sony E and Leica L mount
- Announcement August 19, price unknown
At 1850g, it weighs 150g more than the next Laowa 200mm f/2.0. Of course, we don’t know if this is due to Sigma using a more complex and superior optical design.
