Please define IQ as it relates to lenses for me.

Thanks.

Image Quality

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.

Great lens = high IQ!

 

[Garbz]

if you replace a cheap kit lens with another cheap kit lens you have low IQ

How much more can we milk this one?

I thought IQ stands for intelligence quotient.

 

[Seefutlung]

Great lens = high IQ!

Low IQ = Stupid Lens

Doesn't Stanford-Binet test for IQ?
