It feels like an absolutely monolithic design in the hand, without backlashes and gaps! Previously, I already owned the same one (there is a review here), but I was satisfied with CANON EOS 5D Mark III. Then SIGMA 30mm F1.4 DC DN Contemporary on Olympus OM-D E-M5 Mark II (there is also a review), now I decided to return to this lens for Sony Alpha ILCE-7M2. In all three cases - without disappointment. Firmware Ver.01 at the time of purchase, bug-free. The lens focuses quickly enough and where it is needed. This makes me happy. On the bayonet sits like a glove. I bought a new one and 5.000 cheaper, it pleases even more. ))) As an option, I also considered another glass, namely the TAMRON 28-75mm f / 2.8 zoom (by the way, no less sharp on all FRs), which is 25% cheaper and with a 5-year warranty, but after holding it in my hands I did not dare and chose this one. I don't think I miscalculated. I recommend to buy! P. S. Lens for SONY E looks different than here in the photo, because. it has a longer shank which makes it really bulky.
