Okay, much like the “effective focal length” discussions, there seem to be many “effective aperture” discussions going around as many of these mirrorless interchangeable lens compact system cameras begin to really round out their lens offerings. Well, I guess the micro 4/3 system has while the Samsung NX is getting there and Sony NEX system users still have a small handful of options, but not really here nor there. The fact that so many lenses can be adapted across various formats can complicate the discussion. Along with those who shoot with APS-C DSLR cameras, all references for focal length and depth of field seem to fall back to a full frame/35mm sized sensor as the benchmark. There are some misconceptions as to how the aperture, or focal length affects the exposure or depth of field in these varying formats.
C’mon in, we’ll straighten this all out.
