    These lenses cover the whole 44x33mm frame, right? I wonder what the price range will be.

    The Speedmaster 85mm f/1.2 presented here is a Fujifilm G mount version of the (24×36) lens already available in Canon EF, Nikon F, Pentax K and Sony E lens mounts. It has been tested by LensTip.com among others.

    The Speedmaster 65mm f/1.4 is a genuine G mount lens, albeit deriving from an existing Mitakon.

    Indeed, it appears that its optical formula is close to the one of the 50mm f/0,95 save for a different rear group with an additional element. See below: 50mm f/0.95 on top, 65mm f/1.4 on bottom.

    The eight first elements are almost the same, save for some minor differences in drawing here and there (including E1 being planoconvex on 50mm and biconvex on 65mm, indents in E3 and E4, E4-E5 contact surface being spherical on 50mm and plane on 65mm and E6 being
    biconvex on 50mm and planoconvex on 65mm).

    The most obvious difference is that the 65mm has one more element
    at the rear than the 50mm. The divergence of the last group is more pronounced, sort of playing the role of an integrated teleconverter
    (larger image circle – longer focal length – smaller aperture).
