Best wide angle lens for the sony a6700?
For the a6700, my pick is the Sony FE 12-24mm f/2.8 GM. It frames like 18-36mm on this body, and its constant f/2.8 means the exposure stays the same across the zoom. If you want the best wide zoom here, this is the one.
If you'd rather spend less, the Sony E PZ 10-20mm f/4 G covers 15-30mm equivalent. That's a genuinely wide view for landscapes and interiors, though f/4 is slower, so it suits good light best.
For a faster wide option, the Sigma 16-28mm f/2.8 DG DN Contemporary is a middle ground. It frames like 24-42mm and keeps f/2.8 throughout the zoom.
If you're not sure what the f-number means for your shooting, the lenses guide explains it.
