Avoid if: You're on a tight budget or only need basic functionality

TL;DR: The OM System OM‑5 Mark II packs 1,053 cross‑type AF points, 120 fps burst with a 213‑frame RAW buffer, and 5‑axis IBIS into a 0.9‑lb, weather‑sealed body for serious MFT shooters.

What really sets the OM‑5 Mark II apart is its autofocus system – 1,053 cross‑type phase‑detection points paired with TTL phase‑difference and contrast detection, plus subject‑recognition for birds, vehicles, dogs and more. The camera can fire at 120 fps with continuous focus, and its buffer holds 213 RAW frames at that speed, giving you plenty of room for fast‑moving action.

At 0.9 pounds the OM‑5 is lighter than the Panasonic LUMIX G97 (2.54 pounds) and the G100 (about 1.30 pounds), while matching the Panasonic G7’s weight. Its 5‑axis IBIS delivers up to 8.0 EV steps body‑only and 8.5 EV with a lens, nearly double the 4.5‑stop stabilization listed for the OM E‑M10 Mark IV. Battery life stands at 520 CIPA shots, which is solid for its class but lower than the 360‑shot rating of the E‑M10 Mark IV, and the camera lacks the larger capacity of some larger‑sensor rivals.

Reviewers love the ultra‑fast AF and the 120 fps blackout‑free burst, calling the autofocus “excellent” for wildlife and sports. The compact size and light weight earn praise for handheld comfort, especially with telephoto lenses. On the flip side, users note a steep learning curve – the menu holds over 100 items – and the absence of a built‑in flash can be a hassle for on‑the‑go fill light. The camera’s 20.4 MP stacked BSI Live MOS sensor (17.3 × 13.0 mm) and IP53 dust‑proof, splash‑proof rating round out a well‑rounded package for demanding shooters.

Best for: Professional wildlife and sports photographers who need ultra‑fast AF, high‑speed burst and rugged portability.

Avoid if: You’re a beginner overwhelmed by extensive menus, need long battery endurance, or prioritize low‑light performance over size.

TL;DR: The Panasonic LUMIX G97 packs a 20.3 MP Micro Four Thirds sensor, unlimited 4K 30p video, and 5‑axis Dual I.S. 2 (up to 5 stops) into a weather‑sealed body that weighs 2.54 lb for $847.99.

The standout feature is its unlimited 4K 30p recording at a solid 100 Mbps bitrate, meaning you can capture long takes without hitting a time limit. Coupled with 5‑axis Dual I.S. 2 that delivers up to 5 stops of shake reduction, the G97 stays steady whether you’re filming handheld or on a gimbal.

Compared with the other six cameras in this roundup, the G97 sits at the higher end of the price band and weighs noticeably more than the Panasonic LUMIX G100 and the OM System E‑M10 Mark IV, both of which weigh under 1 lb. It also outpaces the G7’s burst capability: the G97 offers 9 fps mechanical/EFC shooting versus the G7’s 4.6–8.6 fps depending on mode. However, the G100’s EVF resolution lists at roughly 3.68 million dots, edging out the G97’s 2,360,000‑dot viewfinder.

In practice, reviewers praise the camera’s ability to run 4K video without a recording ceiling and the professional‑grade V‑Log L profile that provides 12 stops of dynamic range. The same feedback notes the 4.2/5 star average—below the 4.5 star marks of several rivals—suggesting some users find the ergonomics or battery life (about 290–300 shots per charge) less than ideal.

Technical context adds that the G97’s 20.3 MP CMOS sensor (17.3 × 13.0 mm) supports ISO 100–25,600 for stills and ISO 100–6,400 for video, while the 3.0‑inch vari‑angle touchscreen delivers 1,840,000‑dot resolution. The EVF offers 0.74× magnification and a 20 mm eye point, and the camera includes a 3.5 mm headphone jack and a 3.5 mm mic input for audio control.

Avoid if: Reliability and user satisfaction are your top concerns

TL;DR: The OM System OM‑3 delivers flagship‑level focus, 5‑axis stabilization and a stacked 20.4 MP sensor in a rugged, all‑metal body, but its single card slot and premium $1999.99 price place it at the high end of the MFT lineup.

What really sets the OM‑3 apart is its dual‑mode autofocus system with 1,053 contrast points and 1,053 cross‑type phase points, paired with a stacked 20.4 MP Live MOS sensor and the TruePic X processor. The camera also offers up to 7.5 stops of Sync IS compensation and 6.5 stops of standard IBIS, giving you shake‑free results even at slower shutter speeds.

At 3.34 Pounds, the OM‑3 is heavier than the OM‑5 Mark II (0.9 pounds) and the E‑M10 Mark IV (0.84 pounds), and even heavier than the Panasonic G97 (2.54 pounds). It also carries the highest price tag in the seven‑camera set, sitting at $1999.99, which makes it pricier than the rest of the roundup. While many of the other models use a single SD slot, the OM‑3’s single UHS‑II slot limits redundancy for professionals who need it.

Reviewers consistently praise the camera’s premium feel, the “best‑in‑class” 5‑axis stabilization and the creative dial plus rear‑mounted CP button that unlock computational features like Live ND and Handheld High‑Res. However, users frequently mention the desire for a second card slot and a higher‑resolution EVF; the OM‑3’s 2.36 million‑dot OLED viewfinder has lower resolution than the 3.68 million‑dot EVF of the Panasonic G100. Video‑focused users also note the lack of a microphone input.

Additional technical highlights include a 3.0‑inch vari‑angle electrostatic touch screen with 1.62 million dots, up to 420 shots per battery charge, and low‑light AF sensitivity down to –5.5 EV (ISO 100, f/2.8). Continuous shooting reaches 50 fps with contrast‑AF and 120 fps with phase‑AF, while a supersonic wave filter keeps the camera dust‑protected.

Best for: Those prioritizing quality and willing to pay for premium performance

Avoid if: You're shopping on a tight budget — it's priced at $1999.99

TL;DR: The Panasonic LUMIX G100 packs a 20.3 MP sensor, 3‑mic OZO audio and a 3.68‑million‑dot EVF into a 303 g, fully‑articulating body, but its 4K clips stop at ten minutes.

The standout feature is the three‑microphone OZO audio system with face‑aware tracking, letting you capture clear directional sound without an external recorder. Pair that with an electronic viewfinder that offers approximately 3.68 million dots, and you get a vivid preview even in bright sunlight. The camera’s 20.3 MP Live MOS sensor delivers stills up to ISO 25,600, while the 4K video runs at a 100 Mbps bitrate.

At 590 g overall, the G100 is heavier than the OM System E‑M10 Mark IV’s 383 g package and the Panasonic LUMIX G7’s 0.9‑pound body, but it’s lighter than the Panasonic LUMIX G97, which tips the scales at 2.54 pounds. Battery life yields 250–270 CIPA shots per charge, fewer than the E‑M10 Mark IV’s 360‑shot rating and far below the OM‑5 Mark II’s 520‑shot capacity. Its 49‑area contrast AF system is solid for a vlog‑focused camera, yet it offers far fewer focus points than the OM‑5 Mark II’s 1,053 cross‑type points. On the burst front, the G100 shoots 10 fps with the electronic shutter, outpacing the G7’s 4.6 fps JPEG burst.

Reviewers consistently praise the built‑in OZO microphones and the side‑hinged touchscreen that flips fully forward for selfie framing. The compact 303 g body makes handheld shooting comfortable for long vlogging sessions. However, users note the absence of a headphone jack, which means you can’t monitor audio in real time, and the 10‑minute 4K limit can interrupt longer projects. Professional testers also highlight the lack of in‑body image stabilization for stills, so you’ll rely on lens‑based stabilization or steady hands for sharp photos.

Best for: Vloggers, social‑media creators, and hybrid shooters who need a lightweight camera with strong built‑in audio.

Avoid if: You need advanced in‑body stabilization, long continuous 4K recordings, or professional‑grade video features.
