Any thoughts on these two lenses?
Sigma has promised one in a-mount 'soon' and the Tamron seems well regarded. The only significant feature difference I can see is that the Tamron doesn't have stabilization, while the Tamron will. Since I'll be using it on an A7ii, not sure it matters.
These would be used via the Sony LA-EA4 adapter, of course.
Any experiences with long zooms of either make?
