Price-performance Enormously

I ordered this lens because it has very good Betwertungen get anywhere. I have now tried and duly compared with my other lenses. I still have from Four Thirds times a Zuiko 50mm 2.0, which I occasionally use with adapter of my OM ED-5. One idea was the old Zuiko to sell and replace them with the Sigma. The 50mm Zuiko is very slow along with the MFT adapter already considerably bulkier and autofocus. Both problems should solve the Sigma and does it well.

But you have to remember that I have the same focal length (50 or 60mm) on my M.Zuiko 14-150mm and have always close at hand, but only at f 5.6. So it throws itself on the question of when, then, switches to a fixed focal length. One question that must be answered at any of its own. I do it even more often in the 20mm range, because the Panasonic delivers 20mm 1.7 already noticeable benefits.

If 60mm is planned Portraits urge. I make but rarely. It's always the ad hoc Portraits with whom I best meet my fellow man. The best in the last year I have made all the push, and I checked and found that the adjusted focal length by an average of 130mm (260mm miniature) was much higher. People have mostly only later realized that they were photographed and the pictures they have fallen themselves. Most of these photos were also taken at night in low and artificial light. The camera had some highly regulated to ISO8000 and shutter speeds were also quite long. Nevertheless, most images were properly by the very good stability.

I had at similar conditions from time to time been experimenting with the Zuiko 50mm 2.0, and yes, the images are better than with Zoom, very clear with more contrast. These fixed focal length had by noticeably better quality already well justified, even if keeping the opportunities to use the limited.

From Sigma I had a similar effect expected, only that it should focus just faster.

After many comparisons, I would say that the autofocus when Sigma as expected is considerably faster than the Zuiko 50mm, but rather slightly slower than the M-Zuiko 14-150mm. Definitely very acceptable. (All at relatively low light conditions). In the image quality of contrast to zoom is by far not as clearly visible as compared to the 50mm Zuiko 20mm or the Pana. As such, it really is not worth the most to change the zoom on the Sigma.

Also, the Sigma when imaging scale is far from the Zuiko 50mm (which is also Macro) can replace.
The 50mm Zuiko I'll keep now probably.

Although I'll probably were not using it very often, I'll keep the Sigma. It is so enormously priced for its performance that you would for that reason alone can hardly criticize. The design makes a perfectly acceptable quality impression. The smooth adjustment does not bother me, the manual focusing is fine and soft. In addition, the lens with lens hood and soft lens case is supplied. In the image quality, however, I had hoped that it would be closer to the first-class 50mm Zuiko which is unfortunately not the case. That is why 4 points.
