    Since longer lenses can give the illusion of a shallower depth of field, a 35mm t1.5 on the bmcc will look different than the 85mm 1.2 (assuming both are at the same f-stop) on a 5d.

    It's my understanding you are correct but if you wanted the same DOF, then the 35mm lens would need to use a faster aperture by that 2.3x multiplier so roughly the 35mm at T1.5 would look like the 85mm at f2.2 give or take a point.

    Here is a quick reference chart I posted already, but may be useful here as well.

    Edit: Updated.
    Is there a lens that will make it look like the full 4:3 imaging area? And I realize that the BMPCC needs ultra wide lenses, maybe even fisheye lenses, to get wide shots. What are some lenses that will give you wide shots while still giving you a "flat" image? (meaning not distorted in a "circular" way such as generally with a fisheye)

    Maybe you should specify which 35mm format ? 135 ? APS ? Super 35 ?

    Jeez, I don't even know. i made this little diagram and i have been using it as a reference for myself, i thought people might be interested, it has helped me. It might be super35. Not sure. : /

    I suppose it is to whatever Blackmagic and Metabones are comparing their crop factor.

    John, he means stills 135 film in the leftmost column of the table. Not Super35 film.
