Auxilliary Lenses for Camera Phones?

[black_bird_blue]

You have to love marketing.

An extra lens held over the standard piece of plastic with a bulldog clip, generating an image on a tiny sensor with terrible low ISO capability gives the same result as, say, my f2.8 24-70 on a full frame sensor?

It must be true, of course, because the people selling it have told me so. My really favourite bit is the table at the end, with its ticks and crosses. "And now, the science bit".

Thanks for that laugh.

The table is especially funny. According to them, Nikon lenses have neither coatings, high contrast, or low aberrations. Go figure.

The "75%" discount is laughable, too.  How could such attachments originally cost four times as much as the "discounted" price?

Totally laughable, and scam at the same time. I hope no one buys it.

There is a lecture on the industrie's ability to make plastic mold lenses that outperform classical optics:

We can discuss our doubt that this claim is true, but if it is true, the "cheap plastic mold lens" might not be the limiting factor.

"Ultra Multi Coated"

There is always a minimum factur that limits the overall result. Even were the optics by some miracle perfect, with APO colour correction, free of aberrations, and diffraction limited, the images they project have to be recorded onto a tiny sensor of highly dubious quality.

Thus the scam factor looms extra large here.

The site itself is so filled with dubious images and scripts that my antispam and virus blockers go into Red Alert.

That approach is a far cry from the one linked in the OP. In fact, they are completely opposite.
