>>3970500A small P&S camera has the main advantage of fitting in your pocket. The RX100 series is among the best in its class for fitting the biggest and best hardware into the smallest package. As someone said, you can always have this camera with you, so you'll get the shots others may miss for not having their heavier/larger DSLRs with them. However, focal length is not everything.
What it doesn't do well can be seen through the exposure triangle:
>apertureThis lets you control depth of field, and with smaller sensors and slower lenses, it's more limited than on a full frame, or even APS-C camera. At the extreme end, like with phone cameras, the sensor is so small that basically everything in the frame is in focus, with no real ability to ISOLATE the subject from the background. At the other extreme, a large format camera with a fast lens, you take a portrait of a person and only their eyelashes are in focus...also not ideal, but at least you have more options with the bigger sensor.
>ISOSony is great at engineering sensors that perform, but a physically larger sensor gathers more light, which allows you to work with less noisy images at higher shutter speeds or higher f-stops, as desired by your creative needs. Larger sensors of the same generation also allow you to just have overall less noisy, more detailed images. Larger sensors can work with higher ISO numbers and retain more detail.
>shutter speedI am not sure if the shutter speed itself is limited in the RX100, since that's one of the easiest things to downscale, but as I pointed out above, if the camera's ISO is high enough that detail is being lost, and the lens is not gathering enough light, then you will be forced to shoot with a slower shutter speed in order to expose the photo, which can result in motion blur.
>>3970506>No, the tiny ass sensor gives you worse image quality than your phone.Simply not true. The RX100 cameras have much larger sensors than any phone cameras.
