[HUG] Re: Optical performance of Hasselblad 60-120mm FE Handheld

Per,
I'm looking forward to your answers. I look on the internet for the PDF of the Contax 45-90mm, Pentax 45-85mm, and the Rollei 60140mm zoom lenses. Guess that all would be somewhat similar to each other. 


Thanks and have a good weekend.

Hi Evan,
you'll have to wait at least until Tuesday before I can check all those filter/shade questions. Why the 60-120 wasn't made for 500 cameras? Lots of reasons, like the CF shutter having too small diameter, and all mechanical complications you can dream of. (Imagine getting the aperture and shutter speed setting rings through the cam rings necessary in a zoom lens, or a shutter key-shaft that can handle the long movement of the shutter unit.) The performance of the 60-120 is high, as you say. I won't comment on lenses for other brands, that would just sound biased. But I'm quite sure you can find datasheet for the Contax lens, and probably the Rollei lens, on internet. Best regards, Per Nordlund

    Per,

    I bought a 60120m FE courtesy of Jim Brick's advice. In the
    process, I
    scrounge around for a lens hood , the Polarizer filter, and Polarizer
    Filter ring. It took awhile and I should be receiving the items
    shortly.

    If the lens hood is NOT the correct 60-120mm, but the deeper one made
    for the 350mm FE lens, would this created any problem for me in
    use of
    any of the 93mm filters?  Especially for the 93mm Polarizer, would
    there
    be vignetting at the corners of my image? I do not have the lens hood
    yet, but if it creates problems, I will return it and search out a
    60-120mm lens hood.

    Could I use a SW 86mm polarizer filter on this lens and would
    there be
    any problems with a smaller filter?

    I been shooting with this lens hand held and its quite heavy, but
    sharp
    and contrast y. Its a wonder that this lens was never made or the the
    idea suggested for the 500 series version. Being that it is a of a
    modern design and has the latest multi coating, how does this lens
    compare to the Contax 645 45-90mm zoom, the Rollei 60-140mm, and the
    Pentax 45-85mm?  The mentioned zooms are all of recent manufacture
    and
    are of modern design.
