Re: Figures show mirrorless gaining ground?
In reply to Mike CH, Apr 12, 2013

The trend curve shows the same thing (faster growth for mirrorless).  Thom and others here, seem to be confused by the # of additional sales vs rate of growth.  If one sells 20m units one year and 24m units the next, the increase of 4 million units means a 25% growth rate.  If another product sells 5 m units one year and 7 m units the next the unit increase of 2 million units is a 40% growth rate.

People have an exceptionally hard time visually grasping exponential curves (which growth is).  The text appears to be arguing that the 8% line is growing faster than the 20% line in the first few periods, because the increase is larger.

Note that I'm not predicting that mirrorless cameras will be able to maintain a 20% growth rate indefinitely, but the information presented places them on a 20% growth rate path, currently.

It would be far more correct (and immediately obvious) to plot the numbers on a log chart to compare growth rates:
