A copyable S5 II / S5IIX setup. V-Log with dual native ISO 640/4000, 6K open gate, when the 4K 60p APS-C crop hits, phase-detect AF tuning, and the codec choices that matter.
The Panasonic Lumix S5 II and S5IIX are 24.2MP full-frame hybrids that fixed Panasonic's biggest weakness by adding phase-detection autofocus, while keeping the brand's standout video features: pre-installed V-Log with around 14+ stops of dynamic range, a true dual native ISO of 640 and 4000, 6K open-gate recording in the sensor's full 3:2 area, and an active cooling fan for unlimited takes. The S5IIX adds internal All-Intra and ProRes plus more pro codecs. The setup centers on V-Log, knowing which native ISO to use, and planning around the APS-C crop that kicks in above 30p in 4K. This guide gives you the exact menu items and recommended values, with the reasoning, so you can build a reliable S5 II profile for weddings, documentary, music video, and narrative work.
V-Log comes pre-installed on the S5 II and S5IIX (no paid upgrade needed) and is the profile to shoot when you want maximum dynamic range and a gradeable file. It captures a flat V-Gamut image with around 14+ stops, paired with the widely supported V-Log to Rec.709 conversion LUT for monitoring and grading.
The sensor has a true dual native ISO of 640 and 4000 in V-Log. These are two clean analog gain stages, not a noisy push. ISO 640 is your base for daylight and well-lit scenes with the most highlight latitude. ISO 4000 is the high native base for low light: concerts, night exteriors, dim interiors. It stays remarkably clean because it is a real native stage.
The camera selects the native circuit based on your ISO, so the practical rule is to lean on or near 640 in bright conditions and near 4000 in dark conditions rather than landing on intermediate values, which sit between the two clean stages. If you shoot a standard profile instead of V-Log, the dual-native behavior shifts, so for the cleanest results stay in V-Log and respect the two bases.
The S5 II's headline mode is 6K open gate: it records the full 3:2 sensor area at roughly 5952x3968 up to 30p, capturing maximum resolution and vertical headroom. Open gate is ideal when you need to reframe for both horizontal and vertical (social) deliverables from one take, which is why wedding and content shooters love it. It uses H.265/HEVC Long-GOP to keep file sizes manageable.
For 16:9 work, the camera offers 5.9K and oversampled C4K/4K. Crucially, full-frame readout is available up to 30p; all C4K and 4K above 25/30p (i.e. 4K 50p/60p) come from an APS-C (Super 35) section of the sensor, applying roughly a 1.5x crop. Plan your lenses accordingly: a 24mm becomes a ~36mm equivalent the moment you shoot 4K 60p.
So for your main material, shoot full-frame 24p/25p/30p (or 6K open gate) for the widest, cleanest image, and accept the crop only when you need 4K 60p for slow motion. The S5IIX additionally unlocks higher-bitrate All-Intra, ProRes, and more, but the crop behavior at high frame rates is the same.
Both bodies record 10-bit internally and offer Long-GOP H.264 and H.265 codecs. For most creators, 10-bit 4:2:0 Long-GOP H.265 is the efficient default for open gate and 4K, while 4:2:2 Long-GOP is available for 16:9 modes that need stronger chroma.
The S5IIX is the codec-rich variant. It adds internal All-Intra (up to 5.8K) and internal ProRes 422 HQ in Full HD, plus the ability to record to an external SSD over USB and ProRes RAW / Blackmagic RAW output over HDMI to a compatible recorder. If your workflow demands All-Intra robustness or ProRes for editing, the S5IIX is the body to choose.
For grading-heavy projects, prefer All-Intra (S5IIX) or the highest-bitrate Long-GOP your card supports. For long-form and storage-conscious work, H.265 Long-GOP delivers strong quality at smaller sizes. Set System Frequency (24.00 / 50.00 / 59.94) before the shoot to match your delivery.
V-Log looks flat and low-contrast, so use tools. Load the V-Log View Assist LUT (the V-Log to Rec.709 conversion) so the screen shows a corrected image while recording flat V-Log, and turn on the Waveform monitor, which Panasonic bodies offer natively and is more precise than a histogram for video.
Use Zebra to guard highlights and expose with the dual native ISO in mind: at the 640 base, protect highlights and keep skin comfortably exposed; at the 4000 base in low light, you have clean shadows to work with. Many shooters expose V-Log slightly bright to keep shadows clean, then bring it down in the grade.
Panasonic's V-Log places middle gray around IRE 42 and 18% gray around IRE 42-43 on the waveform, so use the waveform reference rather than eyeballing the flat image. Add the View Assist LUT plus Zebra and Waveform and your exposure will be consistent take to take.
The S5 II and S5IIX are the first Lumix bodies with phase-detection autofocus, a major upgrade over the older contrast-only DFD system. AF is now confident for video, with reliable face, eye, and subject tracking. For interviews, slow the AF speed and lower AF sensitivity for cinematic focus glides; raise both for action.
The 5-axis IBIS is excellent and pairs with Active I.S. for smoother handheld walking footage. Use Active I.S. for run-and-gun and switch stabilization off on a tripod or gimbal to avoid double-correction. Combine it with a wider lens to offset any crop.
Both bodies include an active cooling fan, so they record unlimited-length takes (including 6K open gate and 4K 60p) without thermal shutdowns, with a Fan mode you can set to prioritize quiet operation or maximum cooling. That reliability, plus pre-installed V-Log, is what makes the S5 II such a strong value for long-form and event work.

No. Unlike some earlier Lumix bodies, V-Log comes pre-installed on both the S5 II and S5IIX at no extra cost. It gives you around 14+ stops of dynamic range and uses the widely supported V-Log to Rec.709 conversion LUT for monitoring and grading, so you can shoot flat and grade from day one.
Both 640 and 4000 are clean native base ISOs in V-Log thanks to the dual native ISO sensor. Use 640 for daylight and well-lit scenes for the most highlight latitude, and use 4000 for low light such as concerts, night exteriors, and dim interiors, where the high native stage stays remarkably clean. Avoid sitting at intermediate ISOs when you can land near one of the two bases.
Full-frame readout is available up to 30p. All C4K and 4K above 25/30p (so 4K 50p/60p) is read from an APS-C (Super 35) section of the sensor, applying roughly a 1.5x crop. For 4K 60p slow motion, plan a wider lens; for your main footage shoot full-frame 24p/25p/30p or use 6K open gate.
Image quality and dual native ISO are identical. The S5IIX is the codec-rich variant: it adds internal All-Intra (up to 5.8K), internal ProRes 422 HQ in Full HD, recording to an external SSD over USB, and ProRes RAW / Blackmagic RAW output over HDMI. If you need All-Intra robustness or ProRes for editing, choose the S5IIX; otherwise the S5 II covers most workflows.
Open gate records the full 3:2 sensor area (around 5952x3968) up to 30p, capturing maximum resolution and vertical headroom. It lets you reframe a single take for both horizontal (16:9) and vertical (9:16 social) deliverables, and gives you room to stabilize and punch in. It is a favorite for wedding and content creators who repurpose footage across platforms.
