Review VerdictThe Sigma 90mm f/2.8 DG DN Contemporary produced impressive results during our time with this lens - although it has a few downsides. Image sharpness isn't one of them, though. The lens is plenty sharp, even at f/2.8. Stopping down isn't necessary and there's only a marginal improvement at f/4. We'd even state that images can exhibit the some "3D pop". RAW image distortions are a bit high for such a prime lens as is the RAW vignetting. Image auto-correction will hide these issues, though. Lateral CAs are on the low side. This can't be said about axial CAs, though. In critical scenes, it produces a lot of colour fringing at f/2.8. Stopping down to f/4 does make quite a difference already, though. The quality of the bokeh is excellent again. Out-of-focus highlights are nicely rendered, and the background blur is exceptionally smooth. Image quality is one thing. However, the aspect where Sigma lens tried to make a difference is build quality. The metal lens body just feels awesome.The focus ring handles about as good as it gets with its smooth and dampened action. The aperture ring also avoids the plasticy feeling that we've often seen on other lenses. The weather sealing is rather basic, though. The AF does rely on a stepping motor, which is a bit old school. However, it does the job silently and is pretty fast, so there's nothing wrong with it. If build quality is of lesser concern, then the Sigma lens is probably not for you. Other lenses are just as good optically but faster. However, none of the others can give you the look and feel - and joy - of a classic lens while still offering all the aspects of a modern lens.

Where can this lens be adapted?

The Sony E mount has a flange distance of 18 mm. A plain adapter fits a camera whose flange distance is at least 1.46 mm shorter. How lens adapters work

Native lenses set the aperture, and often the focus, electronically. On a plain adapter they do not work. Use an electronic adapter made for this pair; for many pairs nobody makes one. Fully manual lenses are the exception.
