|positive:||- constant f/2.8 aperture|

|comment:||Build quality is excellent. Plastic exterior, but no squeaks, creaks, or strange noises. Fully internal operation, metal internals, metal tripod mount, thick, ribbed hood, and a 6 year warranty. |
Image quality is great, only pixel peeping will reveal the differences between the Tamron, Sony, and Sigma variants. This lens does have a softer area around 135mm, and is sharpest stopped down to f/4.
Focus accuracy on my copy is a little suspect. There have been multiple times where the camera has confirmed focus, and then looking at the images in post reveals a completely OOF frame. The clutch system to engage the focus ring for MF adds an extra step which changing to MF. The new $1500 version of this lens fixes that by adding USD.
Overall, shooters who aren't making a living off of their work or don't want to shell out for the more expensive Sony, Sigma, or the Mk II Tamron flavors will find a great lens in this one.
