Sigma has always been a popular company for long zoom lenses from the original 50-500mm f/4-6.3 “Bigma” to the expensive and comically large 200-500mm f/2.8. But the new Sigma 150-600mm f/5-6.3 DG DN OS Sports series lens has been hotly anticipated in Sigma’s current transition from DSLR lenses to mirrorless lenses.
The “DN” designation on the new lens denotes that it’s been designed specifically for mirrorless cameras. Now, some of the specs for the new lens have leaked. And it appears that it will be compatible with the Sigma TC-1411 and TC-2011 teleconverters!
