    Question for RB or RZ users

    I have an RZ with 50mm and 90mm lenses. I am looking for a lens to do portrait work but I am not sure which of the 150 or 180mm lenses is best suited. Has anyone got experience shooting head and shoulder portraits with either of these lenses?

    I also saw a 100-200mm f5.2W on line. How would this compare to one of the fixed focal length lenses?

    Thanks,
    Peter

    All of those lenses would be a good choice. I have a Mamiya RZ67 Pro II with a 110mm lens and a 180mm lens and I am very pleased with the 180mm for portrait subjects.
    I haven`t used a 100-200mm f/5.2 lens, but it is only a 2X zoom and should be optically very good in terms of sharpness and resolution and will allow you to crop the image more conveniently.

    I use a 180mm for head & shoulder portrait work. It allows me to give the model breathing space. The 150mm is a slightly faster, and lighter lens, but not so readily available second-hand, you should also consider the 150mm soft-focus lens for additional creativity. The 100/200 zoom is a bit of a lump at twice the weight of the 180mm, that may be a consideration.
    Regards Dave.

    Agree with other posters. It's really a question of whether you prefer portraits with the conventional flatter modeling (-> 180 mm lens) or with slightly more rounding (in which case choose the 150 mm). If working distance is limited (e.g. you're shooting portraits in your spare bedroom), the 180 may be too long, otherwise not much difference.

    Regards,

    David

    Thanks for the info. Any idea what distance would be needed for a head & shoulders portrait using the 180mm lens?

    You can work it out using simple maths.

    Assuming portrait format so 70mm of film height. The ratio of distance to subject size is focal length to film height which, in this case, is 180 : 70

    This means that for every 70mm of subject height, the distance from the subject to camera will be 180mm. Or 180/70 = 2.57 x the subject height.

    So for a head and shoulders shot which may be about 500mmm high, the distance is 500 x 2.57 which is 1285mm or 1.285 metres (4' 2").

    This is a simplified version which does not take bellows extension into account but it should give a rough guide.


    Steve.

    The 150mm has variable soft focus for the fair sex?

    Is there much difference between the lenses with W, WN or no letter after them?

    Try and get one with little machanical damage and no optical. It does not have to be pristine mechanically, just not badly bent, and able to take filters.

    Check the shutter is ok slow and fast speeds.

    P.S. Use a hood.
