I got few additional tidbits about the two Sigma lenses coming on February 21 at 2am Berlin time (That’s February 20 at 8pm New York time)
Sigma 500mm f/5.6
- Sources confirmed it has very fast autofocus
- Sadly frame rate is still limited to 15fps (that’s Sony’s fault and I hope Sony will change this policy)
- Doesn’t take telconverters
Sigma 15mm f/1.4 diagonal fisheye lens
- The lens looks nearly exactly like the current Sigma 14mm f/1.4.
- Same shape, similar weight.
