Future of macrophotography?
This video (not mine) certainly looks impressive.
But as it has advertising purpose it may not cover every potential "cons" of this approach.
Maybe not every macroshot made with it is so high-class as on video.
Even with lousiest phonecam no big problem compose catchy promo video.
But It worth to keep an eye on this technology
Ok, as for cons. From third party reviews they are some softness of images, strong light required, difficulty of manipulating, aiming, stabilizing.
Verdict - it's a great SECOND macro lens, meant for special uses.
