Additional Sigma lens info…
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)… sonyalpharumors.com »
