The Sigma AF 18-50mm f/3.5-5.6 DC is an budget lens which comes with a couple of weaknesses but also surprising strengths. At 18mm the level of distortions and CAs is quite extreme. Vignetting is also an issue at 18mm and 50mm – the latter is quite unusual especially because it doesn’t really help much to stop down here. However, if you limit your aperture settings to f/5.6 and smaller the resolution figures are pretty impressive and comparable to much more pricey zooms out there. Regarding the extremely low price tag Sigma had to implement some compromises on the mechanical side like a rotating front element and a rotating focus ring in AF mode but other than that the build quality of this little lens is actually quite decent. Regarding its weaknesses the corresponding Nikkor AF-S 18-55mm f/3.5-5.6G ED DX may be a better choice though. “¦ READ FULL REVIEW
