Best ND Filters for Sony a7C II (2026): Compact Full-Frame, 4K60 Super 35
The Sony a7C II (ILCE-7CM2) is a 33-megapixel full-frame body that still has no internal ND. Full-width 4K30 is oversampled from 7K. 4K60 is Super 35 only — a 1.5× crop — so the same noon walk that needs two extra stops on a 24–70 GM II at ISO 100 also needs those stops when the crop tightens. The 2026 first buy is the PolarPro Peter McKinnon Edition II Variable ND 2–5 Stop in 82 mm, not the kit 28–60’s 40.5 mm thread.

How We Picked
Three official facts decide the glass. Everything else is a pairing.
- No internal ND. ILCE-7CM2 is a compact stills/hybrid body. Sony does not list an electronic ND. Exposure is shutter, aperture, ISO, and glass on the lens. (Sony a7C II product page)
- 4K30 is full-width from 7K; 4K60 is Super 35. The crop does not add stops. 60 fps still wants ~1/125. The ND math is the same as 4K30; the field of view is not. (DPReview a7C II specifications)
- Native ISO 100, no Dual Base. Stills ISO 100–51200 (50–204800 expanded). There is no FX5-style Dual Gain ISO 800/4000 menu. If ISO 100 is too bright at the shutter you want, the filter has to do the work. (Sony ISO listing)

PolarPro Peter McKinnon Edition II Variable ND 2–5 Stop (82mm) View on Amazon View on B&H
| Range | 2–5 stops |

| Thread | 82 mm |
| Best for | Travel stills + 4K30 / Super 35 4K60 |
The a7C II is a travel hybrid. The first ND should match ISO 100 stills and 4K30 — not a cinema 6–9.
Sony’s own a7C II page lists a 33.0-megapixel full-frame Exmor R sensor, BIONZ XR, full-width 4K up to 30p oversampled from 7K, and 4K60 from a Super 35 / APS-C readout. Native stills ISO starts at 100 (expandable to 50). There is no electronic ND in the body. The compact 28–60 kit is 40.5 mm. The lenses that actually use this sensor — FE 24–70 mm F2.8 GM II, FE 16–35 mm F2.8 GM II, FE 70–200 mm F2.8 GM OSS II — are 82 mm. Buy 82 mm first; step-up rings for 67 mm and 77 mm live in the same pouch.
At 24 fps and 1/50, ISO 100, f/2.8 in hard sun, sunny-16 still wants about five stops. That is the top of a 2–5, not a reason to start on 6–9. Super 35 4K60 does not change the shutter math — 1/125 at 60 fps — it only crops the frame. S-Log3 on this body is a Picture Profile, not Dual Base ISO. There is no Cine EI menu and no second native ISO to hide behind. If the histogram is cooked at ISO 100, the glass has to move, not the gain.
PolarPro’s hard stops keep a 429 g body from hunting between 3.2 and 3.8 on a sidewalk. The Edition II 82 mm ring clears the GM II petal hood. CinemaSeries glass is the same stack used on the a7 IV and a7 V articles — the pairing here is the compact body plus the Super 35 4K60 crop.
- 2–5 matches ISO 100 stills and 4K30 / 4K60 Super 35 on a compact hybrid
- Hard stops; 82 mm GM II hood clearance
- Same 82 mm SKU already on a7 IV / a7 V kits — one pouch for two bodies
- Not enough alone for S-Log3 noon at f/1.4 on a 50 GM
- Overkill on the 40.5 mm kit 28–60 — that lens wants a 40.5 mm or a 67 mm step-up, not this as the only filter

NiSi True Color ND-VARIO 1–5 Stop (82mm) View on Amazon View on B&H
| Range | 1–5 stops |
|---|---|
| Thread | 82 mm |
| Best for | S-Cinetone travel, Fine Tuning |
True Color and a 1-stop floor suit S-Cinetone and Creative Looks more than a 2-stop minimum.
The a7C II is often set to S-Cinetone or a Creative Look for travel JPEGs and 10-bit 4:2:2. Those profiles sit at ISO 100. A 1-stop floor is useful in open shade when 2 stops on PolarPro is already too dark and you do not want to open past f/2.8. NiSi’s True Color coating is the reason this is Value and not a third 2–5 clone.
Fine Tuning on the 1–5 is the same detent system as the 82 mm 6–9. Mark the ring for 1/50 at 24p and 1/60 at 30p on the 24–70 GM II. The 82 mm thread is the same buy as PolarPro — do not drop to 67 mm because the body is small.
- 1-stop floor for shade / S-Cinetone
- True Color on a 33MP stills-heavy body
- Fine Tuning detents
- No 6–9 companion in the same box — noon S-Log3 still needs a second filter
- Silver lever is easy to snag in a sling on a compact body

K&F Concept Nano-X Variable ND2–32 (82mm) View on Amazon View on B&H
| Range | 2–5 stops (ND2–32) |
|---|---|
| Thread | 82 mm |
| Best for | First 82 mm on a travel body |
A first 82 mm ND2–32 for the a7C II. Confirm Nano-X and KF01.1805V1 — ND2–400 is a different filter.
K&F’s Nano-X ND2–32 in 82 mm is the inexpensive way to put glass on the GM II pair without buying PolarPro on day one. The a7C II does not have Dual Gain or eND to paper over a crossed-polarizer X. Stay off the last ½ stop. Do not buy the 40.5 mm Nano-X as the “a7C II filter” unless the 28–60 is the only lens in the bag.
- Real 82 mm Nano-X SKU, not a 40.5 mm kit-lens trap
- ND2–32 range matches the Overall 2–5 job
- No hard stops — easy to over-rotate on a small grip
- ND2–400 listings sit next to this SKU in search results

FE 20–70 F4 G, FE 24–50 F2.8 G, and the APS-C 16–55 if this body shares a bag with an a6700. Do not make 67 mm the first a7C II buy.

only if the kit 28–60 never comes off. That is a vlog kit, not the GM kit.

Frequently Asked Questions
Does the a7C II have a built-in ND filter?
No. ILCE-7CM2 has no electronic or mechanical ND in the body. Neutral density is a filter on the lens.
Why 82 mm on a compact camera?
The body is compact. The GM II zooms that use the 33MP sensor are 82 mm. The kit 28–60 is 40.5 mm — a different, smaller job.
Is 4K60 full-frame on the a7C II?
No. 4K60 is Super 35 / APS-C (about 1.5×). Full-width 4K is 30p and below, oversampled from 7K. The ND stop count does not change; the crop does.
2–5 or 6–9 as the first filter?
2–5. Native ISO 100 and a travel hybrid. 6–9 is the S-Log3 / f/1.2 noon add-on.
Does the a7C II have Dual Gain or Cine EI?
No. Those menus are Cinema Line (FX3 / FX5 / FX30). The a7C II is an ILCE hybrid with Picture Profiles.
Will an a7 IV 82 mm PolarPro fit?
Yes. Same 82 mm Edition II SKUs. The Super 35 4K60 crop is the a7C II-specific note, not a new thread.
Final Verdict
The a7C II is a 33MP compact full-frame with no internal ND, full-width 4K30 from 7K, and Super 35 4K60. Start with the PolarPro 2–5 82 mm. Use NiSi 1–5 if S-Cinetone lives in shade. Use K&F KF01.1805V1 if the first 82 mm has to be cheap. Add the 6–9 only when S-Log3 or an f/1.2 prime runs out of 5 stops.
