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
- Mount: Sigma, Canon, Nikon
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.
