I bought this lens at Best Buy after reading too many reviews and good things about it . Today after Two weeks is my first day that I am trying to learn and read how to use it , So Far so good with my a6600 Camera and my Sony PXW-FS5M2 where I purchased it specially for my fs5m2 . I love taking movies but still learning did not have too much chance to learn on how to set my Camcorder but it all takes time for a beginner like me!!!! But I highly recommend this lens and all Sony products , Never Sony let me down always I was lucky with hundreds of Sony items I bought.
