There is a new crowdfunding project for a Redcat 250mm f/4.9 telephoto full-frame lens by William Optics on Kickstarter. The lens is available also for Pentax cameras and it is described as “The world’s sharpest 250mm telephoto lens ever made for full frame cameras, at Apochromatic specification.”
See also the related posts in the Nikon D850 Facebook group.
Additional information:
Both new converters are fullframe and with all AF systems compatible.
But still no exact shipping date.
Still in late prototype condition.
Maybe because of the new tele lenses.
