SonyAlphaRumors confirmed that Sigma will launch four new lenses in mid July. The very big news here is that those will be the first Sigma lenses exclusively designed for Full Frame Mirrorless systems.
We got an additional confirmation that those lenses will be available for Sony E-mount and the L-mount system first. Nikon Z and Canon R mount versions will be launched later!
These are the lenses:
24-70mm f/2.8 (this lens will be available later after the release of the other three lenses)
