Drop an RW2 file from your Panasonic Lumix FZ300 (DMC-FZ300, sold as FZ330 in Japan) and get the exact shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere.
Check Shutter Count →The Panasonic Lumix FZ300 (DMC-FZ300, 2015 — sold as FZ330 in Japan) is a weather-sealed superzoom bridge camera featuring a 12.1 MP 1/2.3-inch BSI MOS sensor paired with a fixed Leica DC Vario-Elmarit 25–600mm constant f/2.8 lens (24× zoom). It was the first Panasonic superzoom with 4K/30p video and weather sealing. Panasonic does not publish an official shutter durability rating; the mechanical shutter is estimated at approximately 100,000 actuations.
| Model | Release | Sensor | Rated Shutter Life | RAW Format |
|---|---|---|---|---|
| Panasonic Lumix FZ300 / FZ330 (DMC-FZ300) | 2015 | 12.1 MP 1/2.3-inch BSI MOS | ~100,000 (est.) | RW2 |
| Panasonic Lumix FZ1000 II (larger 1-inch sensor) | 2019 | 20.1 MP 1-inch MOS | ~100,000 (est.) | RW2 |
| Panasonic Lumix G7 (ILC comparison, same era) | 2015 | 16 MP MFT | ~200,000 (est.) | RW2 |
Both the FZ300 and FZ330 (same hardware, different regional names) produce identical RW2 files. The same method works for both.
| Actuation Count | % of Estimated Life | Assessment |
|---|---|---|
| 0 – 10,000 | 0 – 10 % | Very low use — near new |
| 10,000 – 30,000 | 10 – 30 % | Low use — plenty of life remaining |
| 30,000 – 60,000 | 30 – 60 % | Moderate use — normal for active photographers |
| 60,000 – 90,000 | 60 – 90 % | High use — negotiate price accordingly |
| 90,000 + | 90 %+ | Near or past estimated life — budget for shutter service |
FZ300 bodies frequently serve wildlife and nature photographers who fire the shutter heavily during extended outdoor sessions. A body with higher count but excellent lens and weather seal integrity may still be a strong buy, especially given the FZ300's rarity as a weather-sealed superzoom — no direct successor was released with the same constant f/2.8 formula.
Both produce identical RW2 files. Shutter count is read the same way from either variant.
The FZ300 is rated splash-proof, dust-proof, and freeze-proof to −10°C, sealed at 78 points. When buying used, inspect the rubber seals around the battery compartment, card slot, and front lens barrel for cracking or compression damage — these degrade over time on a decade-old body and affect the weather resistance claim.

Panasonic does not publish an official rating. Based on the compact shutter mechanism, ~100,000 actuations is the standard estimate for this class of bridge camera.
No. 4K video and 4K Photo mode use the electronic shutter. Only single-frame mechanical releases increment the counter.
Yes — FZ300 and FZ330 are the same camera. RW2 files from both read identically in shuttercount.app.
