Summary: Fantastic lens from Sony. This stops down to f/2.8 creating very creamy bokeh. I use this both on my Sony A33 and my Sony A99 (full frame) and get amazing pictures. Tack sharp focus. This lens is comparable to what you would see in a much more expensive model.
Summary: The lens build quality is very good. Focusing of the lens is smooth, sharp and accurate. Bokeh affect of the lens is very smooth, sharpness is excellent from corner to corner of the frame and contrast is impressive. Even if you have 50mm lens, this is a good addition to your portrait lenses. Very happy to have this lens and definitely recommend to others. You will not be disappointed with the performance of this lens.
Excerpt: for anyone looking to add a nice portrait lens to their collection, this is the lens you want...look at the graphs, look at the online reviews, then look with your own eyes...shooting into the light cropped in at 100%...you will get a little magenta CA that's easily taken care of in post...and the AF tends to hunt in low light situations, the lightweight feature makes it great if you're doing pet or children where capturing a moving subject is part of it..
Excerpt: Considering the optical performance and the price, I could not think of a CON. This is an amazing lens! It covers the FF sensors, but it is the same size as Sony's own 35/1.8 DT lens. Lightweight, compact, and excellent picture quality.<br /><br />I am willing to forgive the plastic construction for all of the positive aspects. The plastic mount might not be durable to withstand a drop or a hard knock, but who handles their gear that way anyhow?
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: The Sony 85mm f/2.8 lens is an essential lens for your kit. If you're new to the SLR world, this lens is perfect for portraits on either crop sensors (Sony Alpha 33/55/77) where it is a medium telephoto lens or on full frame sensors (Sony Alpha 99) where it is normal lens. Colors come through crisp and vibrant. The aperture opens to f/2.8 which lets you get a shallow depth of field or operate in low light.
