Comparing Superzooms by a Figure of Merit: FZ1000 vs. FZ200

In 2003 Rodger Carter and Rick Matthews posted an article on Figure of Merit (FOM) which, in their words, ".. provides a quick, easy way to evaluate various digicams based on their ability to use focal lengths and pixels to obtain the best possible results when the photographer is primarily engaged in the capturing of distant images.": For explanation of how they arrived at this Figure of Merit please visit the link just above.

Their equation is pretty simple: FOM = P x FL^2 (sensor megapixels times the focal length squared). Running these numbers for the FZ1000 and the FZ200 I get:

  • FZ1000: 3216 millon
  • FZ200: 4356 million

The FZ1000 comes pretty close to the FZ200 because the added magapixels (20.1 vs. 12.1) means you can partially make up for the greater reach of the FZ200 by cropping the FZ1000 images.

Interesting, but this is only one "figure of merit". Another relates to the ability of the larger FZ1000 sensor to operate at higher ISO values, so use higher shutter speeds in low light, etc.
