What would it be?

    A lot of pro portrait photographers use a 70-200mm constant f/2.8 lens.

    What would that correspond to in :43: terms?

    Obviously 35-100mm, but what about the max aperture? Not sure how to figure that out.

    (I know this lens doesn't exist for :43:, but I was curious what it would take.)

    If you want similarly shallow depth-of-field, it would have to be f/1.4 to match the 70-200/2.8 on a full-frame sensor.

    Maybe you already know this, the 24-70 & 70-200 equivalents from Panasonic are supposed to be coming sometime, hopefully this year.

    In the mean time you could look at the Olympus 45mm f/1.8. It's a very nice small prime at a good price point.

    Edit: I see from flickr that you have the 45 f/1.8, are you looking for a longer focal length?

    Max aperture is max aperture. There is no "equivalent" for it.

    The Zuiko 35-100mm f/2 is a very good choice for portraits. The m.Zuiko 45mm f/1.8 is also a good portrait lens, but that all depends on how tight you compose. It'll work well for a full bust or more, not so good for a headshot. I would prefer the m.Zuiko 75mm/1.8 for both bust shot and headshot, but that one's not out yet. ;) Full body shots could be done well with the m.Zuiko 45mm f/1.8, but also with the Leica 25mm f/1.4 Summilux or Voigtlander 25mm f/0.95 Nokton. If you have enough space then generally the longer the focal length the better. Get too close for the crop you're shooting and you may get unflattering perspective distortion. However, too long and you could run out of space to move or you may make lighting more difficult (ie, a fill flash on a bracket may get too far, or maybe if you're using optical triggers you may get too far to fire reliably).

    So what kind of portraits do you intend on taking, and in what kind of setting? That would be a much more pertinent question than asking about "equivalent" lenses for an ill-equivalent system.

    Divide the aperture by the crop factor to get equivalent depth of field.

    This is the answer I was looking for.

    I'm not really that concerned about replicating the same thing in :43:; I was just curious. I've got the 45mm f/1.8, and like it just fine. The PanaLeica 25mm is starting to look tempting now too.
