Main trade-off
Sigma 24-70mm F2.8 DG DN II Art for Sony E
735 g for Sony E and an 82 mm filter thread. Its closest wide setting carries a front-contact warning.
Head-to-head
Sigma 24-70 II vs Tamron 28-75 G2: Wider groups or a smaller filter kit?
The short answer
Choose Sigma for crowded indoor groups where 24 mm earns its place. Choose Tamron for a lighter everyday kit when 28 mm is already wide enough. Tamron saves 195 g and uses 67 mm filters instead of 82 mm. Both have similar strong wide-end close-up ratios, but each needs care near the subject. Do not buy either on the assumption that a short sensor-to-subject distance leaves ample space in front.
Before you choose
The reasoning and the trade-offs
The wider lens can be the smaller working kit at an indoor event
A photographer who otherwise carries a second wide lens for group shots may avoid that swap with Sigma’s 24 mm setting. Tamron is 195 g lighter by itself, but the relevant bag contains every lens needed for the day. At a fixed full-frame shooting position, 24 mm covers roughly 17% more distant-plane width than 28 mm. Check the actual room before deciding. The wider setting will not solve every group arrangement, especially when people spread across different distances or stand near the edges.
What this is based on
Indoor group coverage plus a one-bag constraint crossed with minimum focal length and conditional second-lens carrying. Geometric width ratio, not a measured room guarantee.
Main trade-off
Tamron 28-75mm F2.8 G2 for Sony E
28 mm can be restrictive in a crowded room. Wide-end close-up leaves only about 4.4 cm front clearance.

What matters in practice
The differences that matter
The wider lens can be the smaller working kit at an indoor event
A photographer who otherwise carries a second wide lens for group shots may avoid that swap with Sigma’s 24 mm setting. Tamron is 195 g lighter by itself, but the relevant bag contains every lens needed for the day. At a fixed full-frame shooting position, 24 mm covers roughly 17% more distant-plane width than 28 mm. Check the actual room before deciding. The wider setting will not solve every group arrangement, especially when people spread across different distances or stand near the edges.
How we reached this conclusion
Indoor group coverage plus a one-bag constraint crossed with minimum focal length and conditional second-lens carrying. Geometric width ratio, not a measured room guarantee.
A shared filter can matter more than five millimeters of portrait reach
If the bag already contains a 67 mm Tamron telephoto and a video ND filter, the 28-75 can use that native diameter too. Sigma needs 82 mm. A larger filter with step-up rings may be a sensible alternative, but it changes caps, hood clearance and what stays assembled in the bag. Compare the whole accessory purchase before deciding that the cheaper lens offer is the cheaper working kit. No current filter price or universal ring compatibility is assumed.
How we reached this conclusion
Mixed stills/video plus an existing 67 mm accessory system crossed with native filter diameters. Accessory cost direction is conditional, not a priced bundle.
Neither close-up headline guarantees room for a lamp or a moving nose
Both publish about 1:2.7 at the wide end. Sigma explicitly warns about hood removal and front-lens contact, while Tamron gives a 4.4 cm front working distance. For crafts under a lamp, plan light access before choosing on maximum magnification. For a pet that moves toward the camera, back away rather than trying to use the minimum distance. These are useful occasional detail lenses, but the specification alone does not make either an easy substitute for a longer-working-distance macro setup.
How we reached this conclusion
Occasional craft photos plus limited lighting, or a curious moving pet, crossed with wide-end maximum and physical-clearance warnings. No equal working distance inferred.

Meaningful differences
What changes the fit
| What changes | Sigma 24-70mm F2.8 DG DN II Art for Sony E | Tamron 28-75mm F2.8 G2 for Sony E | Why it matters |
|---|---|---|---|
| Nearby group | 24 mm wide end. | 28 mm wide end. | The wide-end choice matters when the photographer cannot move. |
| Carry and filters | 735 g and 82 mm filter. | 540 g and 67 mm filter. | Tamron saves 195 g of lens mass and can share a different existing filter set. |
| Close detail ratio | 1:2.7 at wide, with hood/contact warning. | 1:2.7 at wide, about 4.4 cm front clearance. | Similar ratios do not remove the need to arrange lighting and safe distance. |
| Exposure through the zoom | 24-70 mm constant F2.8. | 28-75 mm constant F2.8. | Neither offers a nominal low-light aperture advantage over the shared range. |
What you give up
Every choice has a cost
If you choose Sigma 24-70mm F2.8 DG DN II Art for Sony E
- Sharing a native 67 mm filter with a Tamron telephoto is no longer possible. A larger common filter needs a checked ring, cap and hood arrangement.
If you choose Tamron 28-75mm F2.8 G2 for Sony E
- An outdoor portrait may fit well while the indoor group still needs another lens. The shared F2.8 label does not solve the narrower room view.
Recommendation switch
The decision flips if...
The group picture keeps forcing a lens change
Choose Sigma 24-70mm F2.8 DG DN II Art for Sony E. 24 mm may cover the missing room width.
28 mm works and a shared light kit matters
Choose Tamron 28-75mm F2.8 G2 for Sony E. Tamron combines lower lens mass and 67 mm filters.
What matters in practice
Before you choose
A compact standard zoom can share the rest of your kit, while the wider lens can save a lens change in the room where you use it most.
What this comparison cannot tell you
- No matched AF or image-quality test.
- Close-up clearance is not inferred from sensor distance.
