“I have the Sigma 18-50mm. I ended up choosing it for the smaller size and weight.”
“However, the lens feels sturdy and very well-built. The Sigma 18-50mm f/2.8 DN DC Contemporary uses a stepping motor for autofocusing. It is pretty fast and noiseless.”
“This makes it the most compact standard zoom lens in its class, when assessed as an AF compatible, F2.8 constant aperture zoom lens for APS-C sensor cameras. Build quality is excellent given the affordable price tag.”
“It is a compact zoom with a nice build quality, a constant F2.8 aperture, and a very good optical performance (outside of a bit of distortion). I could see this being the first upgrade for many photographers, and it could easily be their only lens, too.”
