The Panasonic GH7 or S1 Mark II? One Filmmaker's Honest Take After 6 Months

Choosing between the Panasonic Lumix GH7 and the Panasonic Lumix S1 Mark II is a real decision with a $1,400 price gap sitting between them. Both are flagship cameras aimed at the same kind of shooter, but sensor size, lens ecosystems, and how you actually work day-to-day push them in very different directions.

Coming to you from Nigel Barros, this candid comparison video comes after Barros spent six months using both cameras as loaner units from Lumix. He makes the case that despite the S1 Mark II's full frame sensor and superior low-light performance through dual native ISO, he consistently reaches for the GH7 for his YouTube videos, B-roll, and on-location work. A big part of that comes down to size. Barros points out that there is no full frame equivalent to pairing a Micro Four Thirds body with a lens like the Panasonic Leica DG 12-35mm f/2.8 and keeping the whole kit genuinely compact. When a rig gets too bulky, it stays home, and that kills the work.

He also raises something worth thinking hard about: the lens ecosystem. Micro Four Thirds has a large selection of lenses, but Barros argues it lacks the character-driven, unique options that full frame shooters can access. With full frame, you can pull from thousands of vintage lenses built over decades and get distinctive looks without much hassle. With Micro Four Thirds, getting that same kind of look often means adding a speed booster, which adds cost and complexity. He mentions the Voigtländer Nokton lenses as one of the few Micro Four Thirds options with real character, but acknowledges the selection is thin compared to what full frame opens up.

On the 4:3 open gate question, Barros makes an interesting distinction. The GH7 shoots 4:3 natively, with no crop. The S1 Mark II can shoot 4:3, but it's cropping into a 3:2 sensor to do it. For anyone making content across both horizontal and vertical formats, that difference has real practical weight. Barros is also direct about where the S1 Mark II wins: if you're doing serious hybrid photo-video work, the full frame sensor produces noticeably better stills, and the dual native ISO gives you a meaningful edge in low light. He's not dismissing it.

His bottom line is that at around $1,800, the GH7 hits a sweet spot that the $3,200 S1 Mark II simply can't match for the way he shoots. But he also walks through which type of shooter each camera actually suits, and explains why someone newer to the Lumix full frame system might want to look at the Panasonic Lumix S5 II or Panasonic Lumix S9 before jumping straight to the S1 Mark II.
