Sony DSC-HX99 Focal Length mapping table

【Sony DSC-HX99 Focal Length mapping table】

I had this problem while using my Sony DSC HX-99. When I shoot, I read from the monitor the 35mm-equivalent focal length number. However, when I browse my photos on my computer, the recorded EXIF focal length number is different. Recorded number is the actual focal length, instead of 35mm-equivalent number I read while shooting.

I could not find the official numbers from Sony. I did experiments on my own.

Here is my experiment result. Please note that EXIF focal length sometimes for unknown reason deviates a little. I took several samples and picked the most frequent result in this table.

EXIF Focal Length	35mm Equiv. Reading on Monitor	Mapping Ratio
