Main trade-off
Sigma 28-105mm F2.8 DG DN Art for Sony E
990 g and a 28 mm start. A tight room can still require another wider lens.
Head-to-head
Sigma 28-105 vs 24-70 II: Longer portraits or wider groups?
The short answer
Choose 28-105 when tighter portraits and long-end close details would otherwise require another lens. Choose 24-70 II for nearby groups and a lighter event camera. Both keep F2.8 and 82 mm filters. The 24-70 saves 255 g and starts at 24 mm. Its strongest close-up is at the wide end with a front-clearance warning, while 28-105 reaches its maximum at 105 mm.
Before you choose
The reasoning and the trade-offs
The bigger lens helps only if it removes the lens change you actually make
The 28-105 extends the portrait end by 50% while keeping F2.8. From a fixed position, matching 105 mm with a 70 mm crop retains about 44% of the pixels at a distant plane. That can make the longer lens useful for a seated event. But its 28 mm start can make a nearby group require a separate wide lens. Review which swap interrupts the event more often. The 255 g extra lens mass buys a particular range trade, not universal completeness.
What this is based on
One-camera event plus fixed seating and nearby groups crossed with endpoints, crop area and mass. No claim that range replaces every specialist lens.

What matters in practice
The differences that matter
The bigger lens helps only if it removes the lens change you actually make
The 28-105 extends the portrait end by 50% while keeping F2.8. From a fixed position, matching 105 mm with a 70 mm crop retains about 44% of the pixels at a distant plane. That can make the longer lens useful for a seated event. But its 28 mm start can make a nearby group require a separate wide lens. Review which swap interrupts the event more often. The 255 g extra lens mass buys a particular range trade, not universal completeness.
How we reached this conclusion
One-camera event plus fixed seating and nearby groups crossed with endpoints, crop area and mass. No claim that range replaces every specialist lens.
A small decoration under a fixed light can favor the lower maximum ratio
The 24-70 has the larger maximum reproduction number, about 1:2.7, but it occurs at 24 mm where Sigma warns about front-lens contact and hood removal. The 28-105 reaches 1:3.1 at 105 mm with a 0.40 m sensor distance. If a decoration must stay under a fixed light, the long-end approach may be more practical than moving the lens extremely close at the wide end. Exact front clearance and image quality are not established by these figures. Test the setup before treating either as a dedicated macro replacement.
How we reached this conclusion
Event detail plus fixed lighting crossed with focal position of maximum magnification and explicit front-clearance warning. Practical preference is bounded, not a measured working-distance delta.
The video filter can stay, while the balance of the camera changes
Both use native 82 mm filters, so an existing ND filter does not automatically need replacing. The 28-105 is nevertheless 37.7 mm longer and 255 g heavier in the Sony E versions. A support, camera bag or handheld setup arranged around the 24-70 should be checked with the complete larger lens. Do not infer that a shared filter means a shared balance point or gimbal setting. If the extra reach is seldom used, the smaller lens can preserve more of the existing routine.
How we reached this conclusion
Shared video accessories plus a preconfigured carrying/support setup crossed with equal filter diameter and exact physical differences. No gimbal compatibility guarantee.

Meaningful differences
What changes the fit
| What changes | Sigma 28-105mm F2.8 DG DN Art for Sony E | Sigma 24-70mm F2.8 DG DN II Art for Sony E | Why it matters |
|---|---|---|---|
| Group view | 28 mm start. | 24 mm start. | 24 mm gives about 17% more distant-plane width from the same position. |
| Portrait endpoint | 105 mm F2.8. | 70 mm F2.8. | The longer lens adds framing reach without changing the nominal maximum aperture. |
| Close-up method | 1:3.1 at 105 mm, 0.40 m minimum throughout. | 1:2.7 at 24 mm, explicit front-contact warning at minimum. | The strongest ratio and the most convenient physical position are different questions. |
| Lens and filters | 990 g, 159.9 mm, 82 mm thread. | 735 g, 122.2 mm, 82 mm thread. | The 24-70 saves 255 g and 37.7 mm of listed length. |
What you give up
Every choice has a cost
If you choose Sigma 28-105mm F2.8 DG DN Art for Sony E
- The extra 255 g remains attached during every nearby photograph. It pays back in fewer portrait-range swaps only if you regularly use 70-105 mm.
If you choose Sigma 24-70mm F2.8 DG DN II Art for Sony E
- Cropping to a 105 mm distant view retains about 44% of the pixels. The smaller standard zoom may need a second lens for a fixed-seat event.
Recommendation switch
The decision flips if...
Long portraits and details repeatedly need another lens
Choose Sigma 28-105mm F2.8 DG DN Art for Sony E. The 28-105 extends those jobs at F2.8.
Group width and a smaller camera matter more
Choose Sigma 24-70mm F2.8 DG DN II Art for Sony E. The 24-70 keeps 24 mm and reduces carried size.
What matters in practice
Before you choose
The longer lens can remove a portrait-lens swap while creating a wide-lens swap for the group at the start of the event.
What this comparison cannot tell you
