How Autofocus Works in Photography

When it was first introduced, many people sharply believed that autofocus would never have a clear place in the photography industry, puns intended.

Hands-On with the Sigma 60-600mm f/4.5-6.3 Sports Lens: Lots to Like

The Sigma 60-600mm for Sony E-Mount is a versatile, compelling, and unique lens with a mindblowing 10x optical zoom range. As with any all-in-one lens, it’s not without its compromises, and the $2000 price puts it up against Sony’s native FE 200–600mm f/5.6–6.3 G OSS, even though the Sigma has a more versatile zoom range.

The 13mm, which is equivalent to 20mm on 35mm full-frame, is fairly wide and works well for landscapes or architecture, especially for the low price of $429.
