New Sigma 60-600 coming

Amongst other lenses, the 60-600 is a sport version and rumoured to be lighter than the 150-600 sport.

Yeah, color me doubtful about the image quality from a lens with this much zoom range. I hope I'm wrong!

Hi,

I enjoy my 150-600 C lens very much.
I'm not waiting for this lens...
These specs I have copied from a Canon rumors page:

Sigma 60-600mm f/4.5 – 6.3 DG OS HSM | Sports

• Lens construction: 19 groups of 25elements (including 3 FLD lenses and 1 SLD lens)
• Minimum focusing distance: 60-260 cm
• Maximum photographing magnification: 1: 3.3 (200 mm)
• Image stabilization: 4 stops
• Filter diameter: 105mm
• Size: 120.4mm x 268.9mm
• Weight: 2700g
• Compatible with TC-1401 / TC-2001

2.7 KG ... that's only 0.2 kg less as the 150-600 Sport, 0,8 kg more as my 50-600 Contemporary.
No thanks, not for me.
