RX100 MK1 image file size
As an experiment I compared the image file sizes produced by an RX100 and a Canon S95. Both cameras were set to an image size of 1584x2816 and standard JPEG quality. After taking 100 images in similar situations with both cameras the average image size for the RX100 was 2.1 MB and for the S95 it was only 650KB.
I cannot understand why the files sizes of the RX100 averaged 3 times the size of the S95. The picture quality on a 22inch monitor was similar for both cameras.
I am a newbie so any information would be appreciated to help me understand why there is such a large difference in the test I carried out.
