Sigma 120-300mm f/2.8 DG OS HSM "S"

Review Date: Jun 14, 2015 Recommend? yes | Price paid: $2,450.00 | Rating: 7 

Pros: A zoom lens in this FL is awesome. Build quality is top-notch. Rings have just the right amount of dampening. Pretty sharp @2.8 great by 3.5. Not too heavy to hand-hold.
Focus shift, so you can't zoom to 300 and focus and then zoom out. Tripod collar is horrendous. Vingette at 2.8 is pretty bad. Need to buy the sigma dock to unlock fastest autofocus, and even then, it feels slightly slower than my nikon 70-200 VRII. It's fast enough for sprinting subjects most of the time, but I wish it was faster. Metal lens hood, wish it was carbon fiber for weight loss.

Pros: Light, cheap, and fast focus. Really wide zoom range.
Soft corners, strong vignette. Plasticy feel
