I’ve owned all four Sony RX100 cameras: models 1, 2, 3, and 4. I haven’t kept all of them. When a new model appeared, I bought it and then sold the previous model. All have been great, pocketable cameras, and I’m always amazed at the clarity and color accuracy of each camera. After using all of them, I’m convinced that Sony found just the right combination of the camera’s processor, sensor and lens. These three units work beautifully as a team. I’m especially impressed with the distortion-free Zeiss telephoto lens.
The Sony RX100 cameras from versions 1 though 4 have offered various improvements; some are small, others are more substantial. For example, models 1 and 2 are quite similar, but model 3 has more features than the previous cameras and the photos are somewhat clearer.
But model 4 is the best. It’s more effective than model 3 in low light: It’s almost noiseless at 800 ISO, and noise is very minor at 1200 ISO. The burst mode is 16 frames/second compared to model 3’s 10 fps, and the shutter speed limit has been raised to 1/32,000/second (vs the 3’s 1/2,000/second). Also, the video has been upgraded to 4K (but I still prefer my Canon 7D Mark ll for shooting videos).
The Sony RX100 lV photos below were taken hand-held, and a polarizing filter was used for some of them.
Clearly, the Sony RX100 lV still is king of pocketable cameras. The photo quality compares with some larger, more expensive cameras. Being able to produce such excellent photos with a convenient camera is an incredible plus for both professional and amateur photographers.
