• The Sigma is faster (f/2.8 vs. f/4)
• The Sony is longer (35mm vs. 24mm)
• The Sigma is wider (14mm vs. 16mm)
• The Sony is lighter (518 grams vs. 795 grams)
• The Sony is shorter (98.5 mm vs. 131 mm) – but that difference disappears when zoomed in to 16mm. The Sigma zooms internally.
• The Sony focuses a little faster than the Sigma.
• The Sigma has an AF/MF switch, and a customizable button (for Eye-AF, etc.)
Anyway, I set up my camera on a tripod, turned off IBIS, set a 5 sec. timer, and manually focused the camera on the tall snag in the upper right corner of this frame:
The result? The Sigma (@ f/2.8) on the top, the Sony (@ f/4) on bottom, both zoomed to 16mm.
That's all I needed to see. I'll be keeping the Sigma.
