| Tamron 12-20mm F2.8 (A084) | 570g | Weather-sealed (Tamron's own term is "Moisture-Resistant Construction" — "leak-resistant seals throughout the lens barrel"; the maker does not use the words weather-sealed. Source page states "Length and weight are for Sony E-mount", so 570g is the Sony E figure (the nikon-z entry's 585g comes from a different source and is not in conflict).) |
| Sony FE 16-35mm f/2.8 GM | 680g | Not verified (weight from Sony product code SEL-1635GM; sealing not stated on the source page) |
| Sigma 14-24mm f/2.8 DG DN Art | 795g | Weather-sealed |
