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: Not much else I can say that others haven't, it's a fantastic lens. Not a negative point about it, but something to keep in mind is that 135mm isn't at all wide-angle. You really need to be prepared to move back physically to get the desired shot.
Excerpt: My budget required I choose between upgrading my Sony SLT A65 camera or getting this lens. I chose the lens and I'm glad I did. Although I'm a novice at best, I've received good compliments on some of the photos I took at a recent basketball game from a family member. Low light situations with a medium reach are the two reasons I bought this lens and I am very satisfied so far.
Pros: Fast / accurate auto-focus, Nice Bokeh, Strong Construction, Very good in low light
Excerpt: I compared this lens to the Sigma 85mm f 1.4 because I wanted to do some portraits for my family and use it for nature photography. When comaring them side by side the Sigma was excellent but the Zeiss was magic. I have used it for protraits with spectacular results.Even though the Zeiss was almost twice the cost of the Sigma I think it is worth it.
Pros: Durable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
