Summary: I got this lense to use with the LAEA-4 adapter on the a7ii. I'm not a pro so only have my personal experience but once I calibrated the focus it was simply amazing. I have read people rave about this lens and in my mind it is truly "legendary". I took pictures at a birthday party and the combination of the a7ii stabilization allowed me to handhold without blurry shots. When I shared the pictures with my friends they were floored by the sharpness, color, and bokeh.
Summary: I have been using this lens for a couple of months. It is the best lens that I have owned. I use it with my Sony a65. As an amateur I have been learning my craft and this lens has made a huge difference. There are plenty of reviews on the technical side, so I wanted to express the fact that this lens will up anyone's game and provide beautiful images.
Summary: This lens is the pinnacle of technology and optical quality for portrait artists. Though a bit on the heavy side for use on mirrorless A7R but I have not taken this lens off my camera ever since i received it. Images are rendered beautifully and the bokeh at f/1.8 is amazing. The image center is very sharp when used wide open and creates incredible pictures.
Excerpt: I have a couple of Sony / Zeiss lenses, so I'm familiar with quality, etc of this line. I have the Zeiss 24-70 and the 85 1.4, in addition to the original Sony 70-200 2.8 G. This lens however blew me away. I had heard great things and always wanted to try. Managed to work it in as a rental on a recent photo shoot. Cut to the chase, now I own one. Beautiful colors, focus and detail is crazy. Was everything I hoped the 85 was when I bought that one.
Summary: I bought this lens in mid December, 2013, and I have been stunned by the quality of the photos I have taken with it. It took some getting used to. It is big and heavy, but I love that about it. Sometimes it doesn't focus quickly enough and occasionally it tends to hunt in very low light, but with this lens, when you nail a shot, you knock it out of the park!!! I love it and I use it every chance I get.
