According to figures compiled by versus.com, APS-C cameras with a crop factor of approximately 1.5 outnumber full frame cameras 2.5:1.
(Pentax, Fujifilm, Sony, Nikon, Sigma and once upon a time Samsung use a 1.52 to 1.54 crop factor, while Canon uses smaller 1.6 crop factor sensors. The original APS format has a crop factor of 1.43, or approximately √2, i.e. the sensor area difference is the equivalent of a stop of light.)
Unfortunately, the versus.com figures lump Canon crop cameras with Micro Four Thirds, but it is what it is:
At my count, there are 46 Canon APS-C cameras, so if we include those, full frame cameras are outnumbered over 3:1 by APS-C, and Four Thirds (including Micro Four Thirds) are outnumbered by over 2.6:1 – if, however, we accept Wikipedia’s count of 60 Micro Four Thirds camera models and 18 Four Thirds ones, the ratio is over 3.5:1 in favour of APS-C.
In any case, there have been more APS-C camera models than full frame and (Micro) Four Thirds combined. If we accept versus.com’s figures with the exception of breaking out Canon APS-C and lumping that with all the other APS-C sensors, the ratio
(Full frame + (Micro) Four Thirds) / APS-C
actually comes to a spooky 1.42, or √2.
In a previous article, I suggested that there are better things one can do than upgrade to full frame.
