Hi folks,

The press release for the IBELUX 40mm f0.85 high-speed lens for native Fuji X, Micro Four Thirds, Canon M or Sony E-mount from 'Handevision' can be read here.

A brightest f-number of 0.85 will certainly allow the shallow depth of field previously enjoyed by full-frame cameras/lens systems but I think the reviews will repay reading, as and when they come out, as this will be an expensive lens and the MTF charts, if I'm reading them correctly, promise less than tack sharp imagery when the lens is wide open.

But hats off to Kipon, or Handevision if you prefer, for even attempting this lens. 8)

Bob.

Seeing that MTF chart reminded me of the Canon 50mm f/1.0. Not much contrast or resolution, but that's not why you look at this kinda lens anyway.

Equivalence wise, you've got 60mm f/1.2 for APS-C or 80mm f/1.7 on MFT. Had it been full frame compatible (FE mount?) it would have been really interesting. For the price, I can't get excited. I'm wondering if a metabones speed booster combined with a full frame lens would give you more performance for less cost? That could be one of the many 55mm f/1.2 lenses, not strictly identical but very close.

My gut feeling, they wont shift many of these, even as a niche item. But it will get them noticed and will help with future lenses.

I want to see a picture of that lens. It's probably a pretty big thing. :roll:

There's a picture of the lens in the link in Bob's post.

For micro 4/3, I don't see the need. Manual focus with DoF that thin is going to be difficult for any non-static subject. And if you shoot static subjects, there's the Voigtlander 42.5mm f0.95 which granted isn't an exact match, but pretty darn close for half the price. Or if you want AF, there's the upcoming Pany/Leica 42.5mm f1.2 which granted again isn't an exact match, but it will AF (and probably will cost less than the Ibelux). Or if you're on a budget, there's the Oly 45mm f1.8 which you could buy 5 of and still not spend as much as you would on one Ibelux.
