Thinking about all the posts on the site about 'which lens' and the replies, got me to wondering if the science of light and how it interacts with lens elements etc, if there is a specific lens length that generally produces sharper results, not withstanding any differences in lens design/element composition etc.

We know that some lenses are generally sharper than others, often because the manufacturers have gone a long way to produce a brilliant lens, using technology. But I was wondering if just due the nature of light, if a specific lens length was more suited to being sharper etc, just cause of the way light works.

I am not after a discussion about brands here. I don't want to know that your Nikon this or your Pentax that is the sharpest straight out of camera. I want to know which of your lenses is sharpest, without the brand discussion. We may just find a trend (though we may not).

For me, my 24-70 is the sharpest.
