    1. or don’t shoot close up to increase DOF and can still take advantage of the light it can give you.

  1. “ the lens delivers the 35mm equivalent of an 85mm focal length that is ideal for photo and video portraiture and other detailed studies.”
    Not.
    The equivalent isn’t even right on m43.

  2. 1kg lens from Chinaman for 2k$. Metal and glass for the special price of 2USD per g.

    In comparison to this one, the Lunar suddenly looks like something that actually makes sense.

  3. This lens is not the world fastest lens. It is the fastest in the APS-C-scope (apart from certain X-ray lenses etc, but those don’t really count), but there are many faster lenses in the FF-scope. f/0.85 equals f/1.275 on full frame. For example a Voigtländers 50/1.1 is not only half the price, but likely performs better and allows faster shutter speeds (ie. is faster) on FF than the Ibelux on it’s scope.

    1. From light gathering point of view a 0.85 on APS-C is a 0.85 .

      I guess you are mixing up with the equivalent DOF compared to FF?

      1. No, I am perfectly right. I’ll explain:

        The f-number tells how much light is collected per unit area. FF sensor has 2.25 times the surface area to collect light. Thus you need to convert f-numbers by a factor of sqrt(2.25) = 1.5.

        There are no free lunches – DOF and light collecting go hand in hand. A cell-phone sensor with f/0.85 would not collect anywhere near as much light as a medium format at f/2.8.

        And now the math bit:

        Also, ‘f’ in the f-number stands for focal length. f/0.85 in this case is 40mm/0.85 = 47mm. A full frame camera with the same field of view would have 60mm focal length, thus solving for x 60mm/x=47mm -> x=60mm/47mm=1.275. Thus f/1.275 on full frame is identical to f/0.85 on APS-C.
