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
Summary: Hands down, my favorite lens! It is simply amazing, and I love the images on both the A99 and A77. This is my go-to lens for portraits, low-light settings, and action shots. Bokeh is outstanding. Also have the 85mm Zeiss, and the 135mm is by far superior. Brighter colors, crisper, sharper, than anything else I've seen for Sony. Generally regarded as the best lens that Sony makes, and I totally agree.
