Best Wide-angle Lenses for Sony a6700
The Sony a6700 is a 26-megapixel APS-C hybrid of about 493 g with IBIS. Full-frame 16-35mm glass crops to about 24–52mm and is the wrong default. Wide on this body is native E-mount that starts near 10–11mm. The Tamron 11-20mm F2.8 Di III-A RXD is that zoom — about 16.5–30mm equivalent, constant F2.8, 335 g. Check the Tamron 11-20mm F2.8 on Amazon.

How We Tested
Lenses were scored for APS-C coverage on the a6700, not for full-frame 16-35mm charts. Equivalent field of view had to start around 16mm full-frame equivalent. Constant F2.8 on a 335 g native zoom outranked an FE 16-35mm that hangs off the mount. A 10-20mm F4 G power zoom was kept as the light video extra. FE-only GM wides were not used as the default on this APS-C body.
Best Wide-angle Lenses for Sony a6700: Detailed Reviews
Tamron 11-20mm F2.8 Di III-A RXD View on Amazon View on B&H
| Mount | Sony E, APS-C |
|---|---|
| Focal length | 11–20mm (about 16.5–30mm equivalent) |
| Aperture | Constant F2.8 |
| Weight | 335 g |
| AF | RXD stepping motor |
Why it fits the a6700. Eleven to 20mm on APS-C is the wide range people expect from a 16-35mm on full frame, at constant F2.8, at 335 g. The a6700’s IBIS covers the missing VC. 67mm filters. Buy it as the lens that stays on for rooms and plazas. Skip it if 10mm (~15mm equivalent) and 255 g matter more than 20mm — that is the Sigma 10-18mm.
- ~16.5–30mm equivalent at F2.8
- 335 g on a 493 g body
- 67mm filters
- No VC (use IBIS)
- Not 10mm wide

Sigma 10-18mm F2.8 DC DN Contemporary View on Amazon View on B&H

| Focal length | 10–18mm (about 15–27mm equivalent) |
| Aperture | Constant F2.8 |
| Weight | 255 g |
| Filter | 67mm with included petal hood adapter |
Why it fits the a6700. Ten millimetres on APS-C is a true ultra-wide. 255 g F2.8 is smaller than the Tamron. You lose 18–20mm. Buy it to save mass and gain 10mm. Skip it if 30mm equivalent street wides are daily — stay with the 11-20mm.
- 10mm / ~15mm equivalent
- 255 g constant F2.8
- Cheaper than the Tamron
- Stops at 18mm

Sony E PZ 10-20mm F4 G View on Amazon View on B&H
| Model | SELP1020G |
|---|---|
| Focal length | 10–20mm (about 15–30mm equivalent) |
| Aperture | Constant F4 |
| Weight | 178 g |
| Zoom | Internal power zoom |
Why it fits the a6700. Internal PZ and 178 g make this the video spare. IBIS covers the missing OSS. F4 is why it is budget for stills, not overall. Buy it for gimbal wides. Skip it as the only indoor stills wide if F2.8 rooms are the week.
- 178 g internal PZ
- True 10mm on APS-C
- Gimbal-stable length
- F4, not F2.8
- No OSS in the lens

| Aperture | F1.8 |
| Weight | 181 g |
| Stabilizer | None (body IBIS) |
Eleven millimetres F1.8 at 181 g is the fast room prime. IBIS on the a6700 covers stills. It will not zoom. Keep it beside the Tamron 11-20mm, not instead of it for mixed streets.
- 181 g F1.8 ultra-wide
- About 16.5mm equivalent

- No zoom
- No OSS

Frequently Asked Questions
Whether an FE 16-35mm is the wide lens for the a6700
It mounts, then crops to about 24–52mm equivalent. You carry full-frame wide glass for a standard-zoom view. Native 11-20mm F2.8 or 10-20mm F4 fills the sensor.
Why the Sigma 10-18mm F2.8 is value instead of overall
It is about 255 g and starts at 10mm (~15mm equivalent). It stops at 18mm (~27mm). The Tamron reaches 20mm at F2.8. That extra 2mm at the long end is why Tamron is overall for mixed interiors and streets.
Whether the 10-20mm F4 G PZ is enough
178 g, internal power zoom, 10–20mm (~15–30mm equivalent). Perfect as a video spare. F4 is why stills interiors still want the Tamron F2.8.
What the 15mm F1.4 G is for
219 g, F1.4, about 22.5mm equivalent. Night APS-C wide, not a 10mm room lens. Premium prime, not the zoom default.
Whether the 11mm F1.8 replaces the Tamron
181 g, F1.8, about 16.5mm equivalent. Talking-head and interiors at one focal length. It will not zoom to 20mm. Keep it as the fast prime beside the 11-20mm.
Final Verdict
On the a6700, wide is native APS-C. The Tamron 11-20mm F2.8 is the 16.5–30mm-equivalent zoom. The Sigma 10-18mm F2.8 is the lighter, wider F2.8. The 10-20mm F4 G is the power-zoom spare. Step up to the 15mm F1.4 G for night, and keep the 11mm F1.8 for a single ultra-wide. Leave FE 16-35mm kits on full-frame bodies.
