The Tamron SP 35mm f/1.4 Di USD and Sigma’s 35mm f/1.4 Art are both bright wide-angle primes for DSLR cameras. They share a focal length and aperture, so the choice comes down to build, mount availability and used-market condition. Choose the one that fits your mount and handles best in your hands.
What Each Lens Is For
A 35mm f/1.4 prime is a favorite for street, documentary, environmental portraits and low-light interiors. The wide aperture gives shallow depth of field and lets you shoot with lower ISO in dim places, while the focal length gives a natural, slightly wide view.
The Tamron SP lens belongs to Tamron’s higher-grade SP line and was made for DSLR mounts. Sigma’s 35mm f/1.4 Art comes from the company’s Art line of premium primes. Sigma has also made mirrorless versions, so confirm which one you mean.

How to Decide
- Confirm the mount first. If your camera is a DSLR, both can be options, and used units may be easy to find.
- Think about autofocus consistency. Third-party primes sometimes need autofocus fine-tuning on a given body, so check whether your camera supports it.
- Compare size and weight. Bright 35mm lenses are large, and that matters for travel and street work.
- Examine used copies carefully for condition and signs of drops.
Shooting Guidance
For street work, many photographers use apertures around f/2.8 to f/5.6 with a shutter speed of roughly 1/250 or faster. For low light, open to f/1.4 to f/2 and raise ISO as needed. These are general guidelines; adjust to your scene.
Why the Slug Says Only Sigma
Sigma has made several 35mm lenses, so this comparison assumes the f/1.4 Art model, the closest match in focal length and aperture. If you are weighing a different Sigma 35mm, such as an f/2 or a mirrorless version, look at it on its own terms. The size, weight and mount differences can be large.
Also think about how you will use the lens. A prime that you enjoy carrying will be used far more often than one that stays at home.
FAQ
Is f/1.4 worth the extra bulk?
If you often shoot indoors or at night, yes. For daytime use, an f/2 or f/1.8 prime is smaller and often good enough.
Can I use these lenses on mirrorless cameras?
A DSLR lens can be adapted, but autofocus behavior depends on the adapter and camera. Native mirrorless lenses avoid that question.
The Short Version
These lenses share a focal length and aperture, so mount, handling and condition decide. Choose whichever fits your camera and feels better in use, and confirm specs on each maker’s page.
