Very good performance for Top. Harmonizes very well with the OlympusOM-D E-M10

For recording indoors, I was looking for a good but not very expensive solution. Lichtstark it should be, because I do not like lightning. Originally I had the very Panasonic 20mm 1.7 in use. Because of this, unfortunately, is not one of the fastest, I was looking for an alternative and tried doing the Sigma 19mm 2.8.

And it did not disappoint.

The lens is extensively equipped and the small box is equipped with a Gegenlichblende and a bag.
It's feels very valuable, although the glossy surface is highly susceptible to impressions and scratches. The focus ring is made completely of metal and does not have rubber or ribbing. Nevertheless, it can be easily operated.
A little fear makes the rattle in the lens, which ceases immediately when the camera is on. Battery performance seems to be declining through the lens, but this effect is hardly noticeable. Compared to other M43 lenses that Sigma looks more larger and heavier, yet it blends in very well to my e-M10.

The picture quality is beyond doubt and the AF is very fast!

Just like the Pana 20mm focal length is a bit strange. Architecture is, for example, a bit too long.
Here I would have liked that Sigma had the focal length adapted to the crop factor.

Lowlight it is reflected in the interaction with the E-M10 very well, so I could with the aperture of 2.8 on countless parties and events, make good to very good images, with acceptable ISO values ​​and useful exposure time.

Therefore my full recommendation!
