The Panasonic GH5 and its successor the GH5 Mark II remain two of the most capable mirrorless cameras for filmmakers who need serious video specs without a serious camera budget. Cinema 4K, 10-bit recording, anamorphic modes, dual IS. But the body is only half the story. The other half is what you put on the front of it. As they say: date your camera, marry your lens.
So what is the best lens for GH5 video work? It depends on what you are shooting. Here is a practical breakdown of the lenses that tend to show up again and again in the bags of working GH5 shooters in 2026.
What Makes a Lens Right for GH5 Video?
Before diving into specific picks, worth noting the GH5 native lens mount: Micro Four Thirds. That gives you access to a deep catalog of compact, sharp lenses from Olympus, Panasonic, Sigma, and others. The sensor is a 2x crop; so a 25mm lens, for example, gives you the field of view of a 50mm full-frame equivalent.
For video on the GH5, priorities tend to be:
- Smooth, quiet autofocus (the GH5 DFD is fast but noisy on some lenses)
- Optical stabilization that plays well with the GH5 in-body IS
- Sharpness wide open; you are often shooting at T-stops, not f-stops
- Compact enough that the whole setup stays handheld-friendly
The Best All-Around Lens: Panasonic 12-35mm f/2.8 II
The Lumix 12-35mm f/2.8 ASPH Power OIS II is the lens most GH5 shooters reach for first, and for good reason. It is compact, weather-sealed, and the linear motor delivers near-silent autofocus during video recording. The effective 24-70mm full-frame equivalent covers wide establishing shots through to medium close-ups, making it the most versatile single lens for run-and-gun documentary or event work.
Optically it holds up well wide open at f/2.8, and stopping down to f/4 yields edge-to-edge sharpness. The Power OIS works well with the GH5 5-axis in-body stabilization, so you can get clean handheld shots at 35mm without a rig.
The Budget Workhorse: Olympus M.Zuiko 12-40mm f/2.8 PRO II
Olympus lenses are often overlooked by Panasonic shooters, which is a mistake. The M.Zuiko 12-40mm f/2.8 PRO II is built like a tank (hence the slightly expensive price), focuses quickly and quietly, and the 25-80mm equivalent range covers the same sweet spot as the Panasonic 12-35mm — sometimes cheaper on the used market.
The 12-40mm PRO also has zero focus breathing, which matters if you are pulling focus during video. It is heavier than the Panasonic but the metal construction holds up to field use.
The Low-Light Option: Panasonic 25mm f/1.4 II
For interviews, narrative work, or anything shot in mixed lighting, the Lumix 25mm f/1.4 II ASPH is hard to beat. At f/1.4 you can shoot in conditions that would require pushing the GH5 ISO well past its comfort zone on slower glass.
The 50mm full-frame equivalent is a classic portrait and interview focal length. The mk II version improved the motor for quieter operation, making it genuinely usable for video autofocus.
The Anamorphic Option: Panasonic 8-18mm f/2.8-4
If you are one of the growing number of GH5 shooters exploring the anamorphic mode — the camera can do 4:3 Anamorphic at 6K — the Panasonic 8-18mm f/2.8-4 ASPH is purpose-built for this. It is the only Micro Four Thirds wide-angle zoom that was designed with desqueeze monitoring in mind, and the optical performance at the wider end of the range is excellent. Also a good choice for YouTubers and content creators thanks to its wide angle field of view.
The Telephoto Option: Olympus 40-150mm f/2.8 PRO
For event coverage, wildlife, or any situation where you need reach, the Olympus 40-150mm f/2.8 PRO (80-300mm equivalent) is the sharpest telephoto in the MFT lineup. It focuses fast, is weather-sealed to match the GH5 build quality, and the f/2.8 aperture keeps you competitive in lower light at the long end.
What About Sigma?
Sigma Contemporary and Art primes in Micro Four Thirds are worth considering if you prioritize optical quality above size and autofocus speed. The Sigma 18-35mm f/1.8 DC HSM Art is a cult favorite for GH5 shooters who primarily work on a tripod — its contrast-detect AF is usable but not as smooth as the native Panasonic or Olympus options for handheld video.
What to Buy Used
One practical note: the GH5 used market (and its successor GH6) is mature and well-stocked. Panasonic and Olympus lenses depreciate less than camera bodies, so buying used at sites like MPB, KEH, or your local camera shop is a solid move. Inspect the zoom mechanism and check the filter threads on any used copy, as those are the two most common wear points on mirrorless zooms.
The GH5 is nearly a decade old at this point, but it remains one of the most capable video cameras you can buy used for under $1,000. Pair it with any of the lenses above and you have a serious filmmaking setup for the price of a new consumer mirrorless body. It’s still one of my all-time favorite filmmaking kits.
