The Lumix FZ2500 also uses a 1-inch 20MP sensor that offers exceptional image quality for the class. However, its lens is shorter than the RX10 IV, with an equivalent focal length of 24-480mm. The maximum aperture is from f / 2.8 to f / 4 which, like the RX10 IV, allows reasonably good low-light performance, especially compared to the competition for smaller sensors below.
Where the FZ2500 stands out is the video. Despite being released in 2016, it still offers the best features for the cameraman. It can capture two 4K flavors, Ultra HD (3,840 x 2,160) and Wider DCI (4,096 x 2,160), at a rate of up to 30 frames per second. True 24 fps also supports cinematic looks. Video enthusiasts will also take advantage of features like V-Log L, a flat color profile that preserves a more dynamic range, as well as 10-bit 4: 2: 2 output via HDMI suitable for an external recorder. These are very impressive features on a bridge camera, or really any camera at this price.
On the downside, 4K is recorded from 1.4X clipping, which means it loses some of the wide-angle and ultimately sacrifices some low-light quality by effectively reducing the size of the sensor. Still, serious VCRs that need a portable camera with a built-in long zoom could do much worse.
