Sigma 28-45mm f/1.8 DG DN Art: B&H Photo / Amazon / Adorama
Lenstips published its full Sigma 28-45mm f/1.8 DG DN Art review which you can read in full here or check out the excerpt below:
Pros: solid, weather-proof casing, sensational image quality in the frame centre, especially in the 28-36 mm range, very good image quality on the edge of the APS-C/DX sensor, good image quality on the edge of full frame, negligible longitudinal chromatic aberration, very low lateral chromatic aberration in the 36-45 mm focal range, lack of any noticeable problems with spherical aberration, slight distortion on the APS-C sensor, low astigmatism, sensible performance against bright light, silent, fast, and accurate autofocus, moderate focus breathing, unique parameters.
Cons: very high vignetting on full frame. It is not a big secret: such tests as this one are my favourite ones. After over 20 years of optics testing it is really difficult to surprise me with anything so I am more than happy to handle an instrument with original parameters. If additionally that instrument fares very well in tests I am overjoyed and everyone else is happy. In case of the new Sigma A 28-45 mm f/1.8 DG DN I can say exactly that – you get a lens with unique parameters, unlikely anything I’ve ever seen, and it offers you resolution levels close to record-breaking values.
