rumored 35mm f/1.2 very useful for M6?

Discussion in 'Leica and Rangefinders' started by james_.|1, Feb 11, 2002.

  1. Curious as to whether, with M6's shutter speed selections, the upcoming rumored 35 f/1.2 would be that much better than the f/1.4. Seems there was mention of the M7 being able to exploit the new aperture setting better. Thanks.
     
  2. In my opinion, the only way to exploit a 35mm f/1.2 lenses
    features besides shooting in low light, is to use it in daylight at
    f/1.2 to take environmental portraits.......but the shutter speed has
    to support such a technique....the M6's biggest weekness in my
    opinion. Somthing I used to do with my old 35mm f/1.4 on my
    FM3a.

    <p>

    Anyway a reliable source has advised me that we're all on the
    wrong track about this lens. plus if it was true, who could affford
    it....better call my friend at Microsoft...hm.....what's his
    name...Billy?
     
  3. There is NO upcoming rumored 35/1.2. The guy who wrote about it made
    the whole thing up. There is no such thing.
     
  4. Sure would be nice if voigtlander/cosina made such a superspeed lens .
     
  5. You can shoot at f/1.4 @ 1/60th, but you can't set the current M6 to
    f/1.2 @ 1/90th (or whatever the midway point would be from 1/60th to
    1/125th). If you kept the shutter to the same speed, and used the
    extra half of a stop, you might see some more shadow detail. The
    best use of those in-between apertures is when you are shooting on a
    camera with a step-less shutter, that can actually go in-between
    speeds with a measurable accuracy. Maybe something's coming in this
    regard, but with the thousands of M users out there that won't give
    up their classic cameras, who is to say a half of an f-stop is worth
    getting excited about?

    <p>

    If this lens does exist, I am still at a loss as to why it was though
    to be needed. The current ASPH Summilux is still world class for
    this aperture and focal length. There are still some focal length /
    aperture gaps in the world of real everyday shooters. I'm still
    patently waiting for that small moderate aperture 75mm lens from
    Leica... the one Cosina built several years ago.
     
  6. Ummm, you are all pulling our collective legs, right? Up where I
    live light does not come in whole stop graduations. I frequently
    use the "inbetween" aperture settings. Sometimes plus or
    minus a third stop or a half stop or whatever is required. The
    ability to get a half stop more light on the film could be very useful
    at times. Having said that I have no plans on selling my 35/1.4A
    ever.

    <p>

    The M camera has a stepless shutter! The intermediate speeds
    are useable except between 1/30 and 1/60 (except for 1/50) and
    1/8 and 1/15. The important thing to remember that the shutter
    speed dial resistor only has postions for the marked speeds on
    the dial. So meter, then set the intermediate speed and do not
    meter again until you set the shutter dial back to a marked
    setting.

    <p>

    As to whether there is a new 35/1.2 lens coming, I have no idea.
    It seems rather unlikely to me but then a number of Leica's
    recent offerings have had me puzzled. 135/3.4APO, 50/2.8, LTM
    lenses, etc
     
  7. Well I think the rumor is really just that, but it would be a partner
    to the Noctilux, on the assumption an f1 35mm is just too expensive to
    make. Not quite sure I get the shutter speed argument. Sometime the
    light is such that f1.2 would be the perfect exposure. After all with
    any lens the light may not allow full aperture whether f1.4 or f2.8 if
    you want perfect exposure.

    <p>

    It is all academic anyway. This is just a fantastic rumor.
     
  8. FWIW i had a Canon 50mm f1.2 lens.I have also used the original Leica
    50mm f1.2 lens.Whats the point? Its only a half stop faster than the
    f1.4.The depth of field becomes critical.There is so little,even with
    35mm lenses.I think a 28mm f2.o does have use,but faster,not for me.
    With todays fast films,i reguarly use Fuji 800 color neg.I like the
    warmth,in available lite.Also a lot of photography is done with fill
    flash these days,so really no point whatsoever.
     
  9. John,

    <p>

    I use mid-point apertures also. I was just saying that if your meter
    is reading a correct exposure for f/1.4 and any speed, then opening
    it to f/1.2 without a corresponding shutterspeed increment is kind of
    a non-benefit. Of course if the aperture is wide open (f/1.2) and
    then the meter reads correct for any whole speed, then the benefit of
    that extra half of a stop is clear. I just don't think this is
    something that would make people get rid of their current Summiluxs.

    <p>

    In terms of the question James asked, I still think that any
    advantage of this lens would be best realized on a camera like the
    Hexar RF, (or the M7?) where in minimal light, you could rack it wide-
    open and let the shutter pick anything, like 1/22nd or 1/43rd of a
    second on aperture priority.
     
  10. Yes Al but that argument applies to any lens. Is it always better
    therefore to have an electronic shutter? Yours argumentatively! No
    need to respond, of course. I am at a loose end.
     
  11. Hi Al,

    <p>

    The M cameras already have a stepless shutter as I pointed out
    above. On the M6 cameras you have to meter with the shutter set
    at a marked speed but you can set it any interval you like (except
    for the above mentioned speeds). Whatever the wide open
    aperture is on a lens, you might get to use it with a marked
    speed or not depending on the light levels. A f1.2 lens is just as
    likely to end up with a marked shuter speed as a f1.4 lens is.

    In reponse- sure it would be nice, but why, when it would be
    NICER, but useless for Leica to do such a bold thing.

    <p>

    Go on Cosina....I dare ya!!!!
     
  13. Let me get this straight. Am I reading that if I set the sutter speed
    dial somewhere between 1000 and 500 that I will actually get a shutter
    speed between 1000 and 500?
     
  14. Probably, but on most M's if you set the shutter speed at 1/1000 you
    will also probably get a shutter speed between 1/500 and 1/1000!
     
  15. Hi Jim,

    <p>

    Yes.
     
  16. Wow, I learn something new every day here. Thanks.
     
  17. Me too, very interesting.
     
  18. The problem is you have no way of determining where that intermediate
    speed is. But close enough for Government work, as they say... Or for
    c41 print work, to be more precise.
     
  19. It's funny to come across this thread, realizing that Cosina HAS made a 35mm f/1.2, expected to be available by mid-2003. I guess they took Kristian up on the dare.
