Best ND Filters for Sony a6700
The Sony a6700 is a 26 MP APS-C Exmor R hybrid with no internal ND. Movie ISO starts at 100. 4K/60 is 6K-oversampled across the sensor; 4K/120 adds a crop. 180° shutter at f/2.8 still raises the speed until 24p looks like a slideshow. Mechanical stills stop at 1/4000. Sony does not sell an a6700 ND. The 2026 filter that matches this body is the PolarPro Peter McKinnon Signature Edition II 67 mm 2–5 stop. It is not the FX3’s 82 mm 6–9 LOG default, and it is not a 40.5 mm ring sized only for the kit power zoom.

Street prices move. PolarPro’s 67 mm Edition II often sits around $250; NiSi True Color 1–5 around $160–$200; K&F Nano-X ND2–32 around $60–$80. ND4 is 2 stops, ND32 is 5, ND64 is 6, ND512 is 9. 180-degree shutter is ≈ 2× fps: ~1/48 at 24, ~1/60 at 30, ~1/120 at 60, ~1/240 at 120. S-Cinetone at ISO 100 / f/2.8 / 1/48 is about six stops — 2–5, or f/4 inside that range. S-Log3 on this sensor is typically worked near ISO 800 (CineD’s a6700 lab used ISO 800 / 2500) — that is three more stops and the 6–9 ring, not the first hybrid buy. Sony does not sell a circular ND for this body. Buy 67 mm first (E 16–55 mm F2.8 G and E 70–350 mm G OSS are 67 mm). Step-up rings cover 55 mm (18–135) and 52 / 49 primes. The kit E PZ 16–50 mm OSS II is 40.5 mm — do not make that the only VND. XAVC S-I 4K 59.94p is 600 Mbps on a single UHS-II SD slot — that is a V90 card problem, not an ND problem. Do not stack two variable NDs.
How We Picked These Filters
- What Sony published for this body: ILCE-6700 spec sheet: E-mount. APS-C 23.3 × 15.5 mm Exmor R CMOS. Approx. 27.0 MP total; 26.0 MP effective stills (6192 × 4128); 19.9 MP effective movies. BIONZ XR plus AI processing unit. Stills ISO 100–32000, expandable 50–102400. Movies ISO 100–32000 equivalent. Shutter: mechanical stills 1/4000–30 s, Bulb; electronic stills 1/8000–30 s; movies 1/8000–1 s. Flash sync 1/160. 4K up to 60p with 6K oversampling (Sony). 4K 120p/100p in-camera (Sony); DPReview: ~1.58× crop. XAVC S-I 4K 59.94p 600 Mbps / 50p 500 / 29.97p 300 / 23.98p 240, 10-bit 4:2:2. XAVC HS 4K 119.88p up to 280 Mbps 4:2:2 10-bit. S-Cinetone, S-Log3 (Sony: 14+ stops of latitude), HLG, user LUTs. HDMI: micro Type-D, 4K to 59.94p 4:2:2 10-bit. Spec: RAW output “–”. Single SD slot (UHS-I/II) — no CFexpress. IBIS 5.0 stops (CIPA, FE 50 mm F1.2 GM). Active / Standard / Off for movies. EVF 2.36 M dots; 3.0-type 1.04 M-dot vari-angle LCD. Weight approx. 409 g body only, 493 g with battery and card. Body 122.0 × 69.0 × 75.1 mm. NP-FZ100. 11 fps Hi+. No Pixel Shift. No Dual Gain. No 8K. Sony does not sell an a6700 ND set. There is no built-in ND, unlike the FX6.
- Why ISO 100 still needs glass — and why 2–5 / 67 mm is Overall here: Movie shutter on this body goes to 1 s, not 1/4000. 180° at 24p is ~1/48. Sunny-16 at ISO 100 / f/2.8 / 1/48 is ~6 stops; at f/4 it falls inside 2–5. PolarPro prints 2–5 for general photo / video and 6–9 for LOG / ISO over 400. That split matches this hybrid: S-Cinetone lives at ISO 100; S-Log3 is a 14+-stop grade, not a Cine EI 800 cinema body. Mechanical stills stop at 1/4000 — electronic 1/8000 can freeze a portrait; 2–30 s water cannot. 4K/120 still wants ~1/240 and still has no iris inside the body. Active Mode is a slight crop, not an ND. A no-hard-stop 1–10 VND draws an X — worse on 6K-oversampled 4K60 than on an 8-bit proxy. This is not the a7 IV (full-frame, 82 mm first) and not the FX30 (APS-C cinema, Cine EI).
- 67 mm, the 40.5 mm kit trap, and the cheap-VND trap: Standardize on 67 mm: E 16–55 mm F2.8 G (SEL1655G) and E 70–350 mm G OSS are 67 mm. E 18–135 mm is 55 mm — use a step-up ring. The kit E PZ 16–50 mm F3.5–5.6 OSS II (SELP16502) is 40.5 mm; a 40.5 mm VND will not mount on the 16–55. PolarPro Edition II claims zero vignetting to 16 mm and uses hard stops; the front is unthreaded. NiSi True Color 1–5 67 mm uses a 72 mm front thread and a Swift ND16 press-on for 5–9. K&F’s hard-stop 1–5 is KF01.1802V1; the 82 mm sibling is KF01.1805V1 — wrong thread for this kit. ND2–400 is the wide-range skip. Mounting an FE 24–70 GM II (82 mm) on the a6700 is a second filter, not a reason to skip 67 mm for the APS-C zooms. 4K/120’s extra crop does not add internal ND.
Best ND Filters for Sony a6700: Detailed Reviews
PolarPro Peter McKinnon Signature Edition II 67mm 2–5 Stop View on Amazon View on B&H
| SKU | MFR 67-2/5-VND-ED2 · PolarPro SG-EDll-67-2/5 · UPC 817465026021. 67 mm rear thread. Density 0.6–1.5 (ND4–ND32). CinemaSeries / fused quartz. Haptic clicks. Defender360 case. Street ~$250. |
|---|---|
| On a6700 | PolarPro: 2–5 for general photo / video. Printed zero vignetting to 16 mm — that is the 16–55 G wide end on a 6K-oversampled 4K60 frame. Front is unthreaded; do not plan to stack a second screw-in. Mechanical 1/4000 can freeze many stills. It cannot hold 180° at ISO 100. |
| Not the LOG ring | PolarPro’s 6–9 is LOG / ISO over 400. S-Log3 noon on this body is Layer 2, not the first APS-C hybrid buy. Do not copy an FX3 82 mm 6–9 cart onto a 67 mm 16–55. |
| SKU trap | Edition II 82 mm 2–5 (right range, wrong thread for APS-C G zooms). Edition II 67 mm 6–9 (same $250, wrong first range). Helix MagLock. Peter McKinnon Edition I. A 40.5 mm kit-lens VND as the only filter. |
Why it fits the a6700. This body is a 26 MP APS-C hybrid, not a Cine EI cinema camera. ISO 100 S-Cinetone at a cinematic shutter is a 2–5-stop problem most weeks, and PolarPro built this ring for that sentence in 67 mm. Hard stops are why it is Overall and a $30 ND2–400 is not — 6K-oversampled 4K60 will show an X that an 8-bit proxy hid. Buy 67 mm once; step-up the 55 mm 18–135. Buy NiSi first if you want a True Color 1–5 you can Swift-expand when S-Log3 noon shows up. 600 Mbps XAVC S-I is a V90 SD choice — this body has no CFexpress slot.
Skip this if the week is S-Log3 parking-lot noon or 10-second water — PolarPro 6–9 or NiSi 1–5 plus Swift ND16. Skip an 82 mm copy when the 16–55 G is 67 mm.
- Hard-stop 2–5 matches ISO 100 APS-C weeks
- 67 mm matches 16–55 G and 70–350 G
- Haptic stops; Defender360; 16 mm claim
- Front unthreaded — no screw-in stack
- 6–9 is a second $250 if the week is actually S-Log3 noon

NiSi True Color ND-VARIO Pro Nano 1–5 Stop 67mm View on Amazon View on B&H
| SKU | NIR-TCVND0.3-1.5-67 · EAN 6972949372910. 1–5 stops (0.3–1.5). Nano coat. Removable lever. 72 mm front thread. Street ~$160–$200. Swift 1–9 kit is NIR-TCVNDSWIFT-KIT0.3-2.7-67 if you want the ND16 in the same box. |
|---|---|
| On a6700 | Hard stops, True Color claim, useful from ISO 100 interiors to open shade. Five stops covers most S-Cinetone noon if you can sit near f/4. S-Log3 near ISO 800 / f/2.8 / 1/48 still wants more — that is the Swift ND16 (4 stops) press-on, which NiSi says turns this ring into 5–9 without an X. |
| Wide glass | B&H language on this 1–5 is conservative on ultra-wide (often 35 mm FF / ~28 mm APS-C). PolarPro is the ring that prints 16 mm. On a 16–55 G at 16 mm, treat PolarPro 2–5 as the safer wide claim. |
| SKU trap | 82 mm True Color (NIR-TCVND0.3-1.5-82) when the zoom is 67 mm. Older NiSi ND-VARIO 5–9 Enhanced — not True Color. Swift kits that are Black Mist only. 40.5 mm “kit” True Color as the only filter. |
Why it is Value, not Overall. It is the cheaper True Color hard-stop VND, and the Swift ND16 is a real 5–9 path. It is not the one-ring ISO 100 default PolarPro already cut as 2–5 in 67 mm. Buy this if S-Cinetone / mixed interiors are the week and S-Log3 noon is the exception you expand for. Buy PolarPro if the job starts at ISO 100 and the 16–55 stays at 16 mm.
Skip this if every setup is ISO 100 S-Cinetone and you do not want a second piece of glass — PolarPro 2–5.
- True Color + hard stops under PolarPro money
- Swift ND16 expands to 5–9 for S-Log3 noon
- 72 mm front thread if you must stack a fixed
- 1–5 alone is short for S-Log3 at f/2.8 noon
- 16 mm claim is PolarPro’s, not this page’s

K&F Concept Nano-X ND2–32 Variable ND 67mm View on Amazon View on B&H
| SKU | K&F CONCEPT Nano-X / Nano-Xcel ND2–32 67 mm KF01.1802V1. 1–5 stops (0.3–1.5). Japanese AGC glass, 28-layer coat, ~7.3 mm ring. K&F: no X-cross in this range. Street ~$60–$80. Use a 72 mm cap. |
|---|---|
| On a6700 | Same 1–5 math as NiSi without the True Color / Swift sentence. Fine for S-Cinetone and overcast. S-Log3 / f/2.8 / 1/48 in sun still needs more — stop down, raise frame rate, or add a fixed ND64, do not buy ND2–400 to “get nine stops” on a 6K-oversampled file. |
| SKU trap | KF01.1805V1 (82 mm). True Color KF01.2079 / KF01.2158 if you wanted this Nano-X line. 67 mm ND2–400. ND2–32 + Black Mist / CPL 2-in-1 as the first a6700 ND. A 40.5 mm ring sized only for the 16–50 II. |
Why it is Budget. Hard-stop 1–5, 67 mm, one cheap invoice, a printed SKU. You give up CinemaSeries, True Color branding, and PolarPro’s 16 mm print. The only way this pick fails is Amazon merging it with ND2–400 or an 82 mm listing. If the week is S-Log3 parking-lot noon, spend the extra on PolarPro 6–9 (Layer 2), not on a wider-range cheap VND.
Skip this if the listing says ND2–400, 1–9, 1–10, or 82 mm.
- Named 1–5 SKU under $80
- K&F no-X claim in the ND2–32 range
- Not enough for noon S-Log3 at f/2.8
- Amazon will also show ND2–400 and 82 mm

If You Need Something Else
These two are not cheaper versions of the Top 3. One is PolarPro’s LOG / long-exposure ring in the same 67 mm thread. One is the wide-range VND Amazon will try to sell next to the Nano-X.
PolarPro Peter McKinnon Signature Edition II 67mm 6–9 Stop View on Amazon View on B&H
| What it is | MFR 67-6/9-VND-ED2 · SG-EDll-67-6/9 · UPC 817465026052. 6–9 stops (ND64–ND512, 1.8–2.7). Same CinemaSeries, haptic, Defender360, 16 mm claim, unthreaded front, ~$250 as the 2–5. |
|---|---|
| When it wins | PolarPro: 6–9 is LOG / ISO over 400 / long exposure. S-Log3 noon at f/2.8 / 1/48. 2–30 s water and clouds at ISO 100. Pair with the 2–5 if the a6700 does both S-Cinetone weeks and one S-Log3 commercial. Not the first buy if the job is ISO 100 stills and S-Cinetone. |
| Helix sibling | PolarPro Helix MagLock stays off the Top 3 — different base rings, more money. An 82 mm 6–9 is for FE GM glass mounted on this body, not the APS-C default. |
Buy this after 2–5 is already in the pouch, or when S-Log3 noon / long stills are the look. Do not buy it as a substitute for the hybrid default.
Skip this if the week is ISO 100 S-Cinetone — PolarPro 2–5.

ND2–400 / “1–10 stop” variable NDs View on Amazon View on B&H
| Why it shows up | Amazon titles say “67mm Variable ND” next to the Nano-X. One ring claims ~1–9 stops. There are no hard stops at 5 or 6. That is where the X-pattern lives — worst on a 16–55 G at 16 mm in 6K-oversampled 4K60, which is exactly the a6700 run-and-gun wide end. |
|---|---|
| On a6700 | 26 MP stills and 10-bit 4:2:2 will show the color cast and the X. Buy KF01.1802V1 (1–5) or PolarPro 2–5. Same skip: generic 1–10 VNDs, stacking two variables, a 40.5 mm filter as the only size on a 16–50 II kit that will be replaced by a 67 mm zoom, and any listing that implies the a6700 has built-in ND like the FX6. |
A $30 1–10 is not a 2–5 with haptic clicks. If the camera in the bag is an a6700, the cart says 67-2/5-VND-ED2, NIR-TCVND0.3-1.5-67, or KF01.1802V1.
Skip this if the body is an a6700 and the lens is wider than 24 mm (APS-C). Buy PolarPro 2–5, NiSi True Color 1–5, or K&F ND2–32.

Frequently Asked Questions
What ND strength the a6700 needs
There is no internal ND. Movie ISO starts at 100. 180-degree shutter is ≈ 2× fps: about 1/48 at 24p, 1/60 at 30p, 1/120 at 4K/60, 1/240 at 4K/120. Sunny-16 at ISO 100, f/2.8, and 1/48 is ~6 stops — 2–5 covers it if you can sit at f/4 in the hardest sun. S-Log3 is typically worked near ISO 800 on this sensor (CineD: ISO 800 / 2500) — that is PolarPro 6–9 or NiSi 1–5 plus Swift ND16. Mechanical stills stop at 1/4000; electronic stills at 1/8000. They can replace ND for a frozen portrait. They cannot replace ND for video or for a 2–30 s still.
67 mm vs the 40.5 mm kit vs 82 mm FE glass
Buy 67 mm first. E 16–55 mm F2.8 G and E 70–350 mm G OSS are 67 mm. Step-up rings take 55 mm (18–135) and smaller primes up to that one VND. The kit E PZ 16–50 mm OSS II is 40.5 mm — a 40.5 mm filter will not mount on the 16–55. An 82 mm PolarPro is for FE 24–70 / 16–35 GM II if those live on the a6700; it is a second ring, not the APS-C default. PolarPro Edition II’s front is unthreaded; NiSi True Color 1–5 67 mm has a 72 mm front.
4K/120 crop vs 4K/60 6K oversampling
Sony: 4K up to 60p uses 6K oversampling. 4K 120p is a separate high-frame-rate mode; DPReview measures about a 1.58× crop. The crop changes angle of view. It does not add an iris ND. 180° at 120p is ~1/240, so you need fewer stops than at 24p — still a filter, not a menu. Do not buy a smaller-thread VND “because 4K/120 crops.” The 16–55 G is still 67 mm.
a6700 vs a7 IV vs FX30 glass
Same E-mount. a7 IV is full-frame: 82 mm first, 4K/60 Super 35, no 4K/120. FX30 is APS-C cinema (Cine EI, no stills-first hybrid) — its daylight LOG cart is 6–9, not this page’s 2–5. This page is ILCE-6700. Sony does not put electronic ND in any of these. The FX6 (1/4–1/128) is a different body.
The 600 Mbps codec, single SD slot, and ND
XAVC S-I 4K 59.94p is 600 Mbps. The a6700 has one UHS-II SD slot — no CFexpress Type A. That is a V90 card, not an ND. Movie shutter is 1/8000–1 s. Active Mode is stabilization (Sony: slight crop). HDMI is micro Type-D to 4K/60; spec lists no RAW output. Do not buy an ND “for external RAW.”
Final Verdict
For most Sony a6700 kits, buy PolarPro 67-2/5-VND-ED2, shoot 67 mm with step-up rings, and keep 180° shutter at ISO 100 without raising the movie speed. There is no internal ND. 1/4000 mechanical stills are not a video ND. S-Log3 near ISO 800 in noon sun is PolarPro 6–9 (or NiSi 1–5 plus Swift ND16). Same 1–5 cheaper? K&F KF01.1802V1. Skip ND2–400, skip a 40.5 mm kit-only ring, skip the FX3 82 mm 6–9 cart unless the week is actually LOG on FE glass. 600 Mbps is a V90 SD. 4K/120 is a crop, not an FX6 ND. This page is the a6700, not the a7 IV, not the FX30, and not the accessories roundup.
