Title: Good Sigma 120-300/2.8
Review: I bought this lens for $2,260 from Amazon -(excellent seller,very fast,best prices). The lens generally performs well, F8 improves the sharpness, but is quite soft when used wide open at 300mm (f2.8), especially at the edge of the frame. Auto focus can struggle in low light conditions, but generally seems fast and efficient.It's a 300mm lens that gives an aperture of f2.8 for about half the price of the equivalent Nikon or Cannon primes.The 120-300mm zoom range is really nice to have.
Is the review positive or negative?
