Main trade-off
Tamron 25-200mm F2.8-5.6 G2 for Sony E
Maximum aperture changes with zoom and reaches F5.6 at 200 mm. Expanded close-up claims require firmware 3.
Head-to-head
Tamron 25-200 G2 vs Sony 24-105 G: Distant details or a steady F4 routine?
The short answer
Choose Tamron for daylight outings where distant details keep forcing a second lens. Choose Sony for a constant-F4 routine and documented lens stabilization with still subjects. Tamron saves 88 g and reaches 200 mm, but ends at F5.6. Sony starts slightly wider at 24 mm and stops at 105 mm. Check the actual exposure needed rather than assume Tamron keeps F2.8 throughout its range.
Before you choose
The reasoning and the trade-offs
A family outing can make the long end more useful than the small wide-end gap
A child nearby and a detail across a park can occur before there is a convenient place to open the bag. Tamron reaches 200 mm while Sony stops at 105 mm. Cropping a distant 105 mm image to the same view keeps about 28% of the pixels, using (105/200) squared. Sony’s 24 mm start is only about 4% wider than 25 mm under the same simple geometry. If distant framing is the repeated problem in good light, Tamron addresses the larger range gap. Neither calculation measures optical quality.
What this is based on
Family supervision plus alternating near/far daylight subjects crossed with endpoints and crop geometry. Fixed sensor and distant subject assumed.
Main trade-off
Sony FE 24-105mm F4 G OSS
105 mm can require a substantial crop for distant details. The lens weighs 88 g more.
Tamron 25-200mm F2.8-5.6 G2 for Sony E
- Choose it for
- Reach 200 mm without swapping lenses during a trip.
- Use the lighter 575 g lens and firmware-qualified close-up range.
- Main trade-off
- Maximum aperture changes with zoom and reaches F5.6 at 200 mm. Expanded close-up claims require firmware 3.
Sony FE 24-105mm F4 G OSS
- Choose it for
- Keep a constant F4 maximum across 24-105 mm.

About this comparison
Tamron 25-200 G2 vs Sony 24-105 G for family trips and a one-lens bag. Compare distant framing, constant aperture and firmware-dependent close details.
These full-frame Sony E zooms both begin near 24 mm and target an everyday one-lens trip. A buyer can plausibly trade Sony’s constant F4 and documented OSS for Tamron’s much longer reach and lower mass.

What matters in practice
The differences that matter
A family outing can make the long end more useful than the small wide-end gap
A child nearby and a detail across a park can occur before there is a convenient place to open the bag. Tamron reaches 200 mm while Sony stops at 105 mm. Cropping a distant 105 mm image to the same view keeps about 28% of the pixels, using (105/200) squared. Sony’s 24 mm start is only about 4% wider than 25 mm under the same simple geometry. If distant framing is the repeated problem in good light, Tamron addresses the larger range gap. Neither calculation measures optical quality.
How we reached this conclusion
Family supervision plus alternating near/far daylight subjects crossed with endpoints and crop geometry. Fixed sensor and distant subject assumed.
A planned video exposure can favor the shorter zoom
Sony keeps an F4 maximum through its range. Tamron’s maximum changes and reaches F5.6 at 200 mm. If you want to zoom during a shot while keeping shutter, ISO and aperture fixed, set an aperture available across the range you intend to use before recording. The longer range is still useful, but its F2.8 label does not guarantee a constant exposure at that setting. No exact Tamron aperture transition at 105 mm is adopted, because it was not verified in the selected evidence.
How we reached this conclusion
Fixed video exposure plus zooming crossed with constant versus endpoint-variable maximum aperture. No invented midrange aperture curve or seamless zoom behavior.
A still museum detail and a tiny craft are separate close-work jobs
Sony documents OSS, useful evidence when the subject stays still and the camera is handheld. Tamron’s firmware 3 instead gives a documented half-macro-or-greater route through 25-70 mm. Someone who mixes museum visits with small craft photos should identify which limit matters: camera movement during a longer exposure or getting the object large enough in frame. Neither ability substitutes for good light access and sufficient depth of field. No missing Tamron stabilization claim is treated as proof of absence here.
How we reached this conclusion
Static travel detail plus home craft work crossed with documented OSS and firmware-qualified magnification. Unknown features remain unknown, with no cross-brand stabilization ranking.

Meaningful differences
What changes the fit
| What changes | Tamron 25-200mm F2.8-5.6 G2 for Sony E | Sony FE 24-105mm F4 G OSS | Why it matters |
|---|---|---|---|
| Wide view | 25 mm. | 24 mm. | Sony is slightly wider. This difference is much smaller than 20 versus 24 mm. |
| Distant framing | 200 mm. | 105 mm. | Matching 200 mm with a 105 mm crop keeps about 28% of pixels at distance. |
| Exposure routine | F2.8 wide to F5.6 tele. | Constant F4 with OSS. | Do not assign the wide-end aperture to the entire travel zoom. |
| Carried lens | 575 g and 67 mm filters. | 663 g and 77 mm filters. | Tamron is 88 g lighter before accessories. |
What you give up
Every choice has a cost
If you choose Tamron 25-200mm F2.8-5.6 G2 for Sony E
- Changing focal length changes the available aperture. An exposure planned at the wide end may need revisiting when the subject moves farther away.
If you choose Sony FE 24-105mm F4 G OSS
- A second long lens adds both packing and a swap for distant travel details. Check whether 105 mm already covers the pictures you keep.
Recommendation switch
The decision flips if...
The second telephoto is the main reason the bag gets opened
Choose Tamron 25-200mm F2.8-5.6 G2 for Sony E. Tamron adds substantial reach while saving mass.
The normal range is enough and constant F4 plus OSS matters
Choose Sony FE 24-105mm F4 G OSS. Sony serves that established exposure routine.
What matters in practice
Before you choose
The longer lens can keep the bag closed for a distant subject, while a changing maximum aperture can complicate the evening or video routine.
What this comparison cannot tell you
- No midrange Tamron aperture curve inferred.
- No matched stabilization or image-quality test.
