|comment:||I don't have much to compare to, this is the longest dedicated macro I have, and also has the longest lens hood I've ever owned, and the only one I have with a filter ring control. My copy came with a Tamron branded CPL, I'm not sure if that was an original accessory or if it was added by the seller, but it's a nice plus considering the largish filter ring.|
Focusing speed is what you would expect from a screw-driven macro lens - it's not bad but it's got a long throw. I have not had problems making it work and not had any real issues with hunting. I use the limiter whenever possible on the a77ii to assist in speed. Needed a small MFA to get AF accuracy.
The lens is very sharp, even wide open, and distortion control is good. 3.5 @ 180mm creates a very thin dof, plenty of separation, and pleasant oof. Shooting towards the open end, there's a good bit of fringing, but it's not been difficult to clean up in post, unlike the CA from the Sigma 70-200\2.8 Macro II which tends to be a huge pain.
I haven't intentionally created flare yet, but there's a reason it has that huge hood and you'll need it if you're shooting anywhere close to towards a bright source. Contrast and color is much better with a deep hood on. If I can get away with it I use a smaller 3rd party hood, but at least the big one is there when necessary.
All told, I'm quite pleased with this lens. I can't imagine it would be an everyday carry around lens for most people, but it's a lot of bang for your buck and its a lot of fun to use, which is in many ways, the ultimate test.
I haven't tried this with a 3x teleconverter or macro extension tubes yet to push the extremes, but I will try eventually.
