LEAKED! Lightweight Sigma 500mm f/5.6 E and L-mount lens will be announced on February 21

The image on top show the new 500mm f/5.6 Full Frame E-mount lens that will be announced on February 21. The additional info I got says:

• lightweight lens
• very fast AF on Sony A1
• very low chromatic aberration
• Coming for Sony E and Leica L mount cameras

I am working to get info about the price that surely will be MUCH lower of that of the expensive Sony 400mm GM (Click here) and Sony 600mm GM (Click here).
