Panasonic Lumix DMC-FZ300: The Sealed Bridge Camera That Still Lives Up to Its Reputation
A 4K bridge camera with a constant f/2.8 lens that still delivers in 2026
We review a specific grade B unit of the Panasonic Lumix DMC-FZ300: a bridge camera with a constant f/2.8 Leica lens, dust sealing and 4K recording that arrives at our workshop in excellent condition. Is it still a sensible option on the second-hand market?
- Constant f/2.8 Leica lens across the entire 24-600mm range
- Dust and splash sealing, rare among bridge cameras
- 4K recording with good quality and no recording time limit
- Electronic viewfinder and articulated touchscreen with 1.04M dots
- 12MP sensor already too limited for current standards
- Autofocus can hesitate in low-light conditions
- No 3.5mm microphone connector (only 2.5mm)
When a camera has been on the market for over a decade and still keeps appearing on recommended lists, it must be doing something right. The Panasonic Lumix DMC-FZ300 is one of those rare cases of commercial longevity that can’t be explained by marketing alone: it’s a bridge camera with a combination of features that, to this day, still has no direct competition in its segment. A Leica lens with a constant f/2.8 aperture across the entire zoom range, dust and splash sealing, 4K recording and a decent electronic viewfinder. All in a body that doesn’t weigh like a DSLR with an equivalent lens.
Today in the workshop we have a specific unit, the one matching internal identifier 69cd490537b27510863ae375. It arrived in grade B, which on our scale means it has seen use but shows no serious cosmetic or functional damage. The lab has classified it as “Excellent” condition, and the physical notes are simply “Good”. In other words, this is a unit that has lived a life, but has been well cared for. On the second-hand market, that counts for more than it might seem.

The lack of shutter and battery data is common for this type of compact camera: Panasonic doesn’t record total actuations in a user-accessible way, and the battery is a proprietary cell we can’t test in isolation. What we can confirm is that the body shows no dents, deep scratches or signs of previous opening. The rubber seals are intact, which is a good indicator that the unit hasn’t been exposed to harsh conditions.

The model in general
The FZ300 mounts a 12.1-megapixel MOS sensor with a 1/2.3-inch format. Yes, you read that right: 12 megapixels. In an era where even mid-range phones boast 50MP, this might seem like a joke. But you need to understand the context: this small sensor allows the Leica DC Vario-Elmarit lens, equivalent to 24-600mm, to maintain a constant f/2.8 aperture across the entire range. That’s a huge advantage over other bridge cameras that start at f/2.8 but stop down to f/5.6 or f/6.3 at the telephoto end. At 600mm, having f/2.8 means you can shoot at lower ISOs or with faster shutter speeds, and that makes a massive difference in practice.
The autofocus uses Panasonic’s contrast-detection system with DFD (Depth From Defocus) technology. In good light, it’s fast and accurate. In low-light situations, it struggles more than we’d like, especially at the telephoto end. That’s not exclusive to this unit; it’s a characteristic of the model. The 1.44-million-dot electronic viewfinder is adequate without being spectacular, and the 3-inch articulated touchscreen with 1.04 million dots is comfortable for composing from awkward angles.
What works well
The lens is, without a doubt, the main reason to buy this camera. A 24-600mm range with a constant f/2.8 aperture is something you won’t find on any other bridge camera on the market, even on more recent models. Optical quality is good in the centre of the frame, with some sharpness falloff in the corners at the extreme focal lengths, but nothing that compromises the final result for normal use.
Dust and splash sealing is another of its biggest strengths. It’s not a waterproof camera, but it will handle light rain or a dusty environment without complaint. For anyone into hiking or nature photography, this is a plus you won’t find on most bridge cameras. 4K recording at 30p is solid, with good image quality and no recording time limit, something that was a major differentiator back in its day and remains relevant today.

What shows its age
The 12MP sensor is the main limitation. Not because of resolution itself, which is enough for printing at reasonable sizes or for social media, but because of the sensor size. Noise starts appearing from ISO 800, and by ISO 1600 it’s already quite noticeable. In good light, the camera performs well; indoors or at dusk, you’ll have to push the ISO and accept the loss of detail. It’s a daylight camera, and it’s worth knowing that before you buy it.
Autofocus in video can be erratic at times, especially with fast-moving subjects or in backlit situations. The lack of a 3.5mm microphone connector (it uses a 2.5mm connector with an adapter) is a nuisance for anyone wanting to record video with decent audio. And the microUSB port, rather than USB-C, means you’ll need a specific cable for charging or transferring data.
Who is this unit for?
This specific unit, with its grade B rating and “Good” physical condition, is an interesting option for anyone looking for a versatile camera for travel or nature without lugging around interchangeable-lens gear. The €354 price sits notably below the €451 market average, making it a sensible purchase if you accept its limitations. It’s also a good option for someone wanting to get into photography with a camera that lets you learn without giving up an enormous focal range.
It’s not for anyone seeking image quality in low-light conditions, nor for those who need the flexibility of an interchangeable-lens system. It’s also not for anyone who values resolution above all else. But for outdoor photography, travel, nature and family use, it remains one of the most well-balanced options on the second-hand market.
Verdict
The Panasonic Lumix DMC-FZ300 is a camera that has aged with dignity. Its constant f/2.8 lens and sealing keep it relevant in a segment where no direct competition has emerged. This specific unit, in grade B and at €354, is a recommended purchase for anyone seeking a versatile bridge camera without paying the premium of newer models. It’s not perfect, and the 12MP sensor shows its age, but at this price, alternatives with this combination of features simply don’t exist.
