A new Sony lens patent has been published yesterday (Source Asobinet ). it discloses the design of four GM lenses:
- 400mm f/2.8 (available at Amazon , BHphoto )
- 400mm f/4.0 (more affordable version of the existing f/2.8 GM)
- 500mm f/4.0
- 800mm f/5.6
A patent is not proof that Sony will actually mass produce these lenses. But it definitely shows that Sony is thinking about making them. I would be happy if Sony would produce an 800mm f/5.6 and you?
