Upcoming Sigma "trifocal" lens?
« on: March 03, 2015, 10:00:46 PM »
Sigma is hinting at upcoming "unique" lens, risky and odd like their 18-35 f/1.8. 

Sigma Rumors is thinking it may be a trifocal lens. http://sigma-rumors.com/2015/03/sigma-upcoming-very-unique-lens-thoughts/

I guess the idea is it could be optically simpler and would not have to be good at every FL, just the 3 of them?

That's a really old interview from last fall.  They are just dredging up stuff to improve their search engine rank.

Sigma had already mastered the bifocus: Lenses that nails the focus in 2 places -
1) Focus in front of the subject
2) Focus behind the subject

Ahaha! I've got a couple of those, they could market them to Physicists as Particle/Wave Duality Capturing equipment; there's no way of knowing where those photos are landing until you observe their distribution after the affect... ;)
