    Hmm.
    I have this lens for a second day. Having Sigma 18-200 I'm asking myself why
    I need C10-22 if wide end make such a huge distortion.
    Some guys criticise Sigma for pic quality, but so far I'm happy with my
    Sigma.
    I think that I need some discovery time with C10-22 to appreciate it. I had
    similar situation when I did buy my Rebel, 1st SLR so far.
    Believe me or not but from purchase day it took me 1.5 year that I start to
    like my pic and I start to understand what SLR photography is about. During
    this time I even put it few times on classifieds, but I'm glad I didn't sell
    it:) I'm still in learning procces (hm, who isn't?:)
    I'm planning to go somewhere in the weekend to make some shots. When should
    I go first, cityscape or landscape or...?
    Do you guys remember when you first time start to work with wide angle
    (particular question to C10-22 owners) did you like it at first time you
    attached to your camera?
    cheers

    I've loved my sigma 12-24 since I got it. It did take me time to really
    learn to use it though: knowing how to emphasize or minimize the
    fun-house look.

    Distortion isn't really the right word for what you are describing:
    perspective, or 'wide angle perspective' is better. Here's a few
    exercises to play with:

    Shoot an interior scene first tilting up, then holding level, then down.
    Try cropping the straight one. Shoot perpendicular to the far wall, then
    at an angle.

    Put things in the foreground & take advantage of the ability to put
    those objects in context.

    Shoot a subject near the center of the frame, then put it in the edge,
    and then in the corner. Again, play with whether you are aligned
    perpendicular or the subject is angled.

    Try some closeups, notice how close you can focus & how deep the field
    of focus is when stopped down to f/11 or more.

    Shoot a subject with a lot of 3D relief, compared to a fairly flat
    subject. Align the shooting plane to put portions of the 3D subject on a
    parallel plane to the camera, then put those protrusions at a diagonal
    so one is much closer than the other. Big difference.

    This sounds interesting, but I don't have a clue what you're talking about.
    :)

    Please explain more ... or show us an image? Thanks!

    Mr. Strat Guest

    You need an understanding of optics and photography. The problem is not
    the lens, it's your lack of understanding.

    I'm not completely dump. I understand some photography and optics. What I
    don't know, I'm truing to get from here.

    My camera is back in the shop again :-(

    Simply: things change size dramatically in a wide angle frame depending
    on their distance from the camera so you can exaggerate that way.
    Putting those things parallel to the sensor plane keeps them more normal
    looking, less 'distorted'. 3D objects in the corners can get really weird.

    Umm, not sure I'm any closer to understanding what you said. Would you give
    me some definitions, please?

    3D relief = ?

    shooting plane = ?

    those protrusions = ?

    Thanks!

    Maybe you are asking for too much.

    Maybe you should be looking as a tilt and shift lens if you want to
    photograph tall buildings, as previously mentioned in another post. A lens
    is only a tool at the end of the day.

  9. This is all related to Dancing With The Stars. I saw a few minutes of
    the show this week and realized these are the answers you seek;

    3D relief: after a few minutes of being slapped in the face by the
    whirling bosom of a well-endowed dance partner, a guy realizes why
    flat-chested ballerinas are so popular

    shooting plane: in the disco competition, the winning move is to make
    "finger guns" and act like you're shooting planes out of the sky
    (left-right-left-right)

    those protrusions: see first answer

    Does fixed lens have the same problem? (Is that a problem anyway?)

    Got it.
    I see.

    "Put those protrusions at a diagonal so one is much closer than the other",
    makes complete sense now.

    Try it with a face and a hand instead of 'those protrusions' if you
    prefer :) equidistant (parallel) to the sensor or one further away than
    the other (diagonal).

    It is the same way we see with our eyes. A fisheye projection is an
    alternative.

    When I said it makes complete sense to me now, I was playing along with
    Tully's joke. I still don't have a clue what you are describing. I guess I
    only will when I see an image (and I know your camera is being fixed).

    The 'protruding' tile paving is diagonal to the sensor: exaggerated in
    the foreground with a steep perspective. If you crop where the tile
    meets the building on one of those doors, the tiles look about the same
    size in the foreground & background: like a long lens.

    The parallel building looks square and undistorted. Even if it was
    angled, putting it in the center keeps it realistic looking.

    Here's an exaggerated diagonal:

    Here's a missed opportunity for a superwide:

    Here's one with the subject close to parallel but stair-stepped:

    This shows how things in the middle of the frame look straight but it
    falls apart in the edges:

    The left side original has the doors the width of 2 foreground tiles,
    the enlarged crop at right has the door almost 10 tiles wide.

    You're just talking about perspective, right? I have no problem with that,
    just with understanding the incomprehensible gobbledegook about
    "protrusions" and "3D relief".
