    IQ just means image quality.

    Chromatic aberration, resolution, distortion, and sharpness all fall into the IQ area.

    :thumbup:

    The optical quality of a lens tends to be assessed in quantitative terms; resolution at different apertures, (lack of) vignetting and aberrations...

    Then there's the more qualitative and subjective aspects, such as the "bokeh" or appearance of the out-of-focus areas and highlights.

    Personally with regard to IQ and lenses, I prefer to think in terms of Lens Quality rather than Image Quality. A lens by itself can't produce an image of any quality.

    Low IQ = Stupid Lens

    Doesn't Stanford-Binet test for IQ?
