    Question Wide-eyed and bushy-tailed

    Okay ... as a lot of you know, I like to attempt non-traditional photography. Hey, everybody has their quirks.

    Along those lines, I was looking at this new lens from SIGMA. Yeah, I know ... Mr. I-despise-SIGMA's-QA-program himself. Well, every once in a while they do offer something off the beaten path and here it is:

    Look at that focus gap between min and max!!! LOL That's nuts.

    Imagine 4.5mm f/2.8 ... talk about a sky-filling lens. You can't miss much with this baby and at $799 ... well within reason for such an awesome width -> 180

    The question is ... should I or what? LOL

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.

    I think this may be the lens for 'GotToyota?"

    hmmm crazy. Are all the shots rounded? I like the regular 16mm fish's perspective.

    Just looked at the review, and yes, all the shots are rounded. Are those images in the review where you can sorta see a frame around the shot the inside of the lens showing up on the image?

    Looks like fun Don, but seems awfully specialized. $799 seems like a lot of the way towards a CZ 16-35 or 24-70.

    Never been tempted with one of these. Perhaps you need to be a bit warped yourself.

    Here's kind of comparison between different fisheye-perspective, done by Tiktaalik, on POTN with a Canon EOS DSLR.

    You can see how the longer focal lengths begin to chop down what you see from the "fisheye effect."

    But if you think that's something ... here is an older 6mm f/.28 fisheye, from Nikon ... that could actually see "behind" it, with a 220 circle.

    The smaller one is an f/5.6 version. Aperture determines the size of the first element, remember? This "hunk of glass" weighs quite a bit, 5200 grams (11.5 lbs)

    ah, interesting. 4.5mm is really quite excessive. ~9mm seems like it would be all encompassing.

    This figure makes 15mm look small lol!
