Bright and sharp

Actually not a big push fan, I have decided to go this fast lens, after I had rolled infinite amount of material on the net. To combine this range on a crop camera equivalent to about 28 to 50 mm small image simultaneously with a maximum aperture of 1.8 seemed to me almost as a panacea. Sometimes it takes next to my full manual M9 also the (fast) autofocus and then I do the usual exemption that the Leica lenses together provides me the Crop quite important. Vorneweg said it works, even in this focal length range. You can with this lens sufficiently indemnify. It lacks a bit of typical 3D-Touch, I love my Zeiss lenses so. Nevertheless, I am quite satisfied with the results of my little Canon 650D. Offenblendig the Sigma is a little soft and the Bokeh generally uneasy. However, the focus at the center is OK, you can still bring out a lot of the pictures with little tutoring in Lightroom, so using the raw data format. I iris usually starting at 5.2 to 2.3, when it comes to me to the exemption. Then the results in the targeted area are razor sharp. In landscape photography it needs anyway aperture from 8, then the Sigma (almost every other modern lens like anyway) is blameless. Portraits can photograph it, although this focal length this is not really suitable. I iris then also easily, otherwise there is a danger that only one eye at a sharp one gets not utter plan face attitude of the model z. B. and the rest of the head does not fit. The Verzeichnungen- especially at close range between 18 and 24mm remain within the limits, to me they are not yet overly negative impression. A giant Nachteil- but that's just physics and not to be changed is the weight and size of the lens. It just drags nearly a kilo in addition around with you. However justify the results, and one saves some fixed focal length, quite the drudgery. Good also the Sigma mitliefert a lens hood, which is not common practice in the photographic industry.
