The new star?

Announced it was already a few days. Now Sigma has the 8 March - presented 16mm Ultra Wide Angle. An APS-C which is converted a 12-24mm lens. I was very excited to be able to test it yourself, since the first reactions were really positive. With the Sigma one also comes with an APS-C focal length areas in front of the advance the VF cameras were reserved with a 10-24 eg. Anticipation, the wide angle is not suitable for full format but is just as APS-C version available for purchase. The two already existing wide-angle zoom not surprising.

The DX version of the sigmoid colon is as always decent and packed with all the accessories that is needed. Also with integrated Streulichblende. I can not verkneiffen this in my reviews for the Canon Note bayonet, because this is a real nuisance for me at the Canon optics. The Sigma is very well made and with the roughened surface has a very pleasant feel. Zoom and focus Siering are handy and can be operated well. Both runs without play and mechanically sound. But since I had honestly expected nothing less. The AF is quick and super quiet, also can manually intervene in the focusing operation. The Sigma is a Innenfokussierer is glad that the overall length does not change when zooming, and the tube does not unload. Unfortunately, the use of filters is not possible.

Already at the first pictures I was excited by the Sigma. The Abbldungsleistung on the 7D is easy to only be described as impressive. The vignetting and distortion errors are in a Ultra Wide course available, but are limited, which is not necessarily to be expected with a UWW so. Both falls significantly from tame as my Canon 15-85, what is often to stand without correction hardly.
CAs play no role in Sigma. The sharpness of 8-16 convinced at all levels. Until the edges that Sigma is really sharp. Even with Auschnittvergrößerung the detail and the high resolution of the sigmoid colon is striking. Various reputable IT sides when it comes to have the photo is indeed shown with numbers and praise the Sigma to the skies in terms of line resolution. The minimum focusing distance with 24cm and is convinced example below the very good Tokina 11-16.
I am fascinated by the Sigma by its sharpness to make his way images and the width of which is in these images and their particular perspectives. But convince yourself. In Nikon Photography, as well as on various Canon pages already there nice sample pictures from Sigma.

Short and sweet

Positive:
+ Processing and haptics
+ Imaging performance
+ Low vignetting and distortion, mind you for a UWW!
+ Resolution
+ Priced really attractive

Negatives
- No filters used

Neutral
o not fully compatible format

My conclusion: For me, the Sigma is the first choice in the (ultra) wide-angle lenses for APS-C format. The Sigma leaves everything behind what I had so far on the camera.
Even my beloved Pentax Fish (10-17 at K20D) must remain times zuhaus well here and there. Definitely a new star on UWW sky. 5 Stars
