The Sony 16-35mm f/2.8 GM and the Tamron 17-28mm f/2.8 are both bright wide zooms for full-frame E-mount cameras. The Sony offers a wider range and a premium build, while the Tamron is smaller, lighter and narrower in coverage. Choose the Tamron for portability, and the Sony for range and professional demands.
What Each Lens Does
The Sony 16-35mm GM is a flagship wide-angle zoom. It covers 16mm to 35mm, which spans dramatic wide scenes to a natural moderate-wide view, and it is built for professional work in tough conditions.
The Tamron 17-28mm is a compact f/2.8 wide zoom. Its range is shorter, so it behaves almost like three primes in one body, and it is popular with travellers and street and landscape shooters who want small kit.

How to Decide
- Carry weight: if you hike, travel or shoot all day, a lighter lens may be the one you actually bring.
- Range: 35mm is handy for portraits, environmental scenes and everyday use. 28mm is tighter on that end, so you may switch lenses more often.
- Width: 16mm is slightly wider than 17mm, which matters in tight interiors.
- Filters: a smaller filter thread means smaller and lighter polarizers and neutral density filters.
- Build and handling: flagship lenses usually offer more custom controls, stronger sealing claims and tougher barrels. Read what the maker says.
Who Should Choose Which
Choose the Sony if wide-angle work is your living, if you need the extra range, or if you want maximum build quality. Choose the Tamron if you want a bright wide zoom that fits in a small bag and you rarely need beyond 28mm. For a baseline in landscape work, try an aperture around f/8 for good depth, then refine for your subject.
- Choose the Sony for event work, wide portraits and interiors.
- Choose the Tamron for travel, hiking and compact street kit.
FAQ
Is 17mm wide enough for architecture?
For most interiors and buildings it is, though 16mm offers a bit more room in cramped spaces. Cropping and perspective correction in editing software also help.
Do both lenses support the same autofocus features?
Autofocus motors and body integration differ between makers. Look at each maker’s page for what is supported on your camera body.
The Short Version
The Sony 16-35mm GM is the larger, more capable all-round wide zoom. The Tamron 17-28mm is the light, compact option for people who value portability. Match the lens to how you shoot and how much you carry.
