This is a problem of higher resolution. More pixels means the lens must be
larger to gather more light to continue to illuminate each pixel at the
same intensity compared to a lower resolution camera.

Lower resolution cameras tend to be roughly the scale of the human eye,
which is what makes them suitable for afocal (behind-the-eyepiece)
photomicrography. The 5 and 8 megapixel cameras of late are relatively
huge in scale.
