True to form, Canon releases another mediocre "film" lens

Discussion in 'Canon' started by RichA, Sep 2, 2008.

  1. Unfortunately build quality and pleasing haptics don't come with
    the f/1.8. Still, a good buy, unless you already have a fast 50mm.
    If they need what the Sigma delivers and not what the Canon does,
    yes, absolutely. Choice is good. (Just as an independent example:
    in portraits, seeing every pore is not always the best thing.)

    "Well?" If it was working well, it wouldn't be a piece of junk, would
    it? But I get your point, Canon is loath to change anything that
    might cost them $0.02 extra cents.
    What has that got to do with the design of the glass??

    98% on the irony meter.

    But it isn't a piece of junk. You don't want to accept that because
    you're a stupid bigot. You think that other people should waste
    money in order to support your ignorance.

  5. My fault ... I meant "very well, near perfect in an
    imperfect world".
    If you had a brain, you'd surely use it, and if you had the
    sense God gave a goose, you'd stop talking with your backside.
    So, pray tell, how do you manage life on spinal jerk reflexes?
    Since you don't own a camera, much less a working camera,
    much less a Canon ...
    According to *you* Canon doesn't design for digital, only
    for film. I want to hear your inane justifications. Really.
    I need that for a study called "Braindead or Brainless --- real and
    artificial dumbness". You are a fascinating study in that regard,
    even though one has to wash hands and brain after each contact.

    : You're right! All the non-third-party 50/1.4 normal lenses are copies of the
    : Zeiss Planar, which was designed in 1896.

    : Well, the latter half is right (1902, actually).

    : The only new 50/1.4 is the Sigma, 50/1.5, which is a radically different

    : f/2.0 than the Canon 50/1.4. However the Canon pulls ahead at f/4.0.

    Forgive me if I'm responding to a typo, but how does *any* f/1.5 lens perform
    better at f/1.4 than the Canon lens?

    : I'd give Sigma many points for updated that hoary old design, I only
    : hope they can maintain some level of quality, unlike with other lenses
    : they produce. Also, their 30mm f1.4 was a "new" design incorporating
    : low-dispersion glass, which did a good job on the colour error issue
    : such a lens would experience, but the residual spherical aberration
    : when the lens is wide open is terrible, and the less is far less sharp
    : with lower contrast at all apertures than either Nikon or Pentax's
    : 35mm f.20 lenses. In such a case, given the 1.4 aperture produced
    : such poor images, it almost renders the speed gain useless.

    Rich, have you ever actually used that lens? (And before you answer, you may
    wish to consider that your answer will be read by at least several who *have*
    used it.)
