Best Wildlife Lenses for Sony a6700
The Sony a6700 is a 26-megapixel APS-C hybrid of about 493 g with IBIS. A 70-350mm covers Saturday sidelines. Birds and distant mammals on this sensor want a longer native-or-FE zoom, because 350mm is only about 525mm equivalent. The Sigma 150-600mm F5-6.3 DG DN OS Sports is that reach: about 225–900mm equivalent, optical OS, 2,100 g. Check the Sigma 150-600mm on Amazon.

How We Tested
Lenses were scored for APS-C field of view on a 493 g a6700, not for a full-frame 100-400mm walk. Equivalent reach past 600mm was the baseline. A lighter 150-500mm with VC was credited when it stayed under 1.8 kg. The native 70-350mm was kept as the lens you can actually hike with. An internal-zoom 200-600mm was kept as the paid FE reach option. Indoor 70-200mm F2.8 glass was not used as a wildlife default.
Best Wildlife Lenses for Sony a6700: Detailed Reviews
Sigma 150-600mm F5-6.3 DG DN OS Sports View on Amazon View on B&H
| Mount | Sony E, full frame |
|---|---|
| Focal length | 150–600mm (about 225–900mm equivalent) |
| Aperture | F5–6.3 |
| Weight | 2,100 g with tripod socket |
| Stabilizer | Optical OS |
Why it fits the a6700. Sigma lists this Sports zoom at 2,100 g on E-mount, 95mm filters, OS, and a 150–600mm range. On APS-C that is about 225–900mm. The a6700 already has IBIS; OS still matters at 600mm. It is a monopod lens on a 493 g body. Buy it when small subjects stay far. Skip it for a trail day — that is the 70-350mm G at 625 g.
- About 900mm equivalent
- OS plus a6700 IBIS
- Starts at 150mm, wider than a 200-600mm
- 2,100 g on a 493 g body
- Extending zoom, F6.3 at 600mm

| Aperture | F5–6.7 |
| Weight | 1,725 g without tripod mount |
| Stabilizer | Tamron VC |
Why it fits the a6700. Tamron’s 150-500mm is 1,725 g without the foot, with VC and VXD AF. On APS-C you get about 750mm equivalent, then you give up 500–600mm. Buy it to save 375 g versus the Sigma. Skip it if the hide is always at 600mm.
- VC and about 1,725 g
- Cheaper than the Sigma 150-600mm
- VXD AF
- Stops at 500mm

Sony E 70-350mm F4.5-6.3 G OSS View on Amazon View on B&H
| Model | SEL70350G |
|---|---|
| Focal length | 70–350mm (about 105–525mm equivalent) |
| Aperture | F4.5–6.3 |
| Weight | 625 g |
| Stabilizer | Optical SteadyShot |
Why it fits the a6700. This is the native G zoom: 625 g, OSS, linear AF, a true APS-C image circle. It is the budget card because it is the one you can wear, not because 350mm replaces 600mm. Buy it for trails. Add the Sigma when the subject will not come closer.
- 625 g with OSS
- Fills the APS-C frame
- Starts at 70mm
- About 525mm equivalent, not 900mm
- F6.3 at 350mm

Frequently Asked Questions
Whether the 70-350mm G is enough for wildlife on the a6700
It is 625 g and about 105–525mm equivalent with OSS. That covers larger animals and closer birds. It is the budget card here because 525mm equivalent still leaves small birds small. The 150-600mm is the far-field lens.
Why the Tamron 150-500mm is value instead of overall
It is about 1,725 g without the foot, with VC, and it stops at 500mm (about 750mm equivalent). You save weight and money versus the Sigma and give up 500–600mm. That is a real trade on APS-C, which is why it is value.
Whether an FE 200-600mm is sharper than the Sigma on this body
Both are about 2.1 kg. The Sony zoom is internal, so the length stays put on a gimbal or a monopod head. On APS-C you use the center of the frame. Buy the Sony when internal zoom matters. Buy the Sigma when 150mm and the lower street price matter.
What the 100-400mm GM adds on APS-C
About 150–600mm equivalent at F4.5–5.6 and 1,395 g. Faster and sharper than the 150-600mm, shorter at the long end. It is the handheld GM option, not the 900mm-equivalent default.
Whether a 70-200mm F2.8 belongs on this wildlife list
It becomes about 105–300mm equivalent. Useful for large animals in low light. It is not a bird lens on the a6700. Keep it for sports, not as the far-field default.
Final Verdict
On the a6700, far wildlife is the Sigma 150-600mm, about 225–900mm equivalent. The Tamron 150-500mm is the lighter VC zoom. The 70-350mm G is the hike lens. Pay for the FE 200-600mm when you want internal zoom, and keep the 100-400mm GM for a faster handheld reach. Do not stop at 350mm if the subject is a small bird.
