I bought as "Always top" for Sony A99V the lens. The weaknesses of the lens, however, are known with little effort to eliminate in the image editing ... if's but then interferes times! Processing is not too loud in the green zone, the focus. The back has normal resistance, not too light and not too heavy! Tube extends not alone. Small, lightweight high speed, in conjunction with the not too heavy A99V a great combination! Overall, one can when one considers the price is not much go wrong. From my very good 4 star for the lens and not a price-performance star to ... makes 5!
