How each score was set
Usability 6.7 /10
From published features and owner comments · not a lab test.
- Specs published10.0/10
- All six printed: Sony E and L mounts, 28-70mm F2.8, stepping-motor autofocus, 470 g, 72.2 x 103.5 mm and a dust and splash resistant mount.
- Warranty and repairs7.0/10
- One-year limited warranty with a 3-year Sigma USA extension per The Digital Picture; Sigma's own US warranty page was not readable, so the terms are third-party.
- Firmware and compatibility4.0/10
- Two of five: a firmware download tab on the global product page and a mount list. The USB dock works on L-mount only, and no manual was read.
- Price and extras6.0/10
- Sigma USA lists it 'as low as $989', above the $899 launch price; a hood and caps are included and nothing else is required. Shipping terms were not read.
- Support and owner reports5.0/10
- Sigma USA has account pages and a dealer locator; contact channels and hours were not read. Reviewers cite the 28 mm end and close focus as the main owner gripes.
