Sigma official teaser for a product announcement on February 21st, 10 a.m. JST

For me this means I have to wake up early and live blog at 2am my time 🙁

Sigma will announce those two new lenses:

• 500mm F5.6 DG DN OS | Sports
• 15mm F1.4 DG DN DIAGONAL FISHEYE| Art

Sigma 500mm f/5.6 specs:

• Lightweight lens…less than 1,5kg and so the lightest telephoto prime lens you can buy.
• Very fast AF on Sony A1 (lens has linear motor)
• The lens sharper than the Sony 200-600 G
• very low chromatic aberration
• Coming for Sony E and Leica L mount cameras
• Price just under $3,000
• Announcement on February 21.
