    wow, that is one massive piece of glass! For those you want smaller yet have the similar focal length, consider the nikkor 85 f1.4 on Speed booster on an APS-C Sony camera. Much smaller footprint, smaller camera body, and still get f1.0 light gathering.

    and probably a lot better bokeh?

    the nikkor will have bokeh equivalent to 1.4, whereas this 90mm f1.0 will have bokeh equivalent to 1.0.

    Another excellent lens that mates well with Speed booster is the Canon 85mm f1.2 which will give 0.9 light gathering.

    For close by portraits it looks quiet nice. How close does it focus?
