Sigma 90mm F2.8 Macro A-mount lens review by leon3536
|leon3536#10258 date: Jun-2-2012|
flare control: 4
|ownership:||I own this lens|
|price paid:||87 USD (used mint)|
|negative:||Green and purple CA wide open|
|comment:||I got the Quantaray version from ebay and it's identical to the Sigma. This lens is incredibly sharp at all speeds and all distances. Great for both portrait and macro. The long focus ring gives you precise focus in both auto and manual mode. |
My copy had back focusing problem, but it's not a problem on the A77. The micro adjustment was at -9! If you shoot something with high contrast at F2.8 expect to see a ton of purple CA.
