  • I think you're vastly underestimating the market. A tonne of people works out to about twelve of them (eleven, if it's US males). I'd say, it could easily be twice that number!

    Sorry, couldn't...

  • Ah, I see what you mean now. Yes, a thorough test will use a test target, or it might miss something. And the target would need to be photographed at various zoom settings and at various distances...

  • Yes, some zoom lenses have complex distortion:

    But if a straight line remains straight, you're good, there's no distortion.

  • "If it is very important for you and if you will buy the product only if it doesn't have distortion,then my advice is to search for a real distortion test of the product.Or you will never be sure...

  • For a travel solution, I don't think the IQ differences will be visible at all, let alone make much difference. Unless you travel with a tripod. If you need more reach, that's a different story.
  • Now, are there any other muscles that clench at dramatic moments that GoPro is supposed to capture? Something that wouldn't interfere with hanging on for dear life? People would pay money to see an...

  • UWA close-up portraits are more like caricature than "interesting and excellent". A bit of a niche, to say the least. But I guess, to each his own...

  • Just out of curiosity, what kind of wide-angle shots would call for shallow DOF?

  • Perspective distortion has a very distinctive look, easily recognizable here. Fisheye distortion has its own look, not present in this image.
    Perspective distortion is not caused by a lens defect,...

  • House and pole "leaning over" is perspective distortion. It's literally what the lens saw from its position and angle.

    The reason it looks distorted is that you're looking at the scene at a...

    "But it can't focus or change focal length. You would need a different metamaterial for each focal length and focus distance."

    Same thing with lenses made out of ground glass. You need...

  • Created discussion thread What's next in rugged cans?
    Now that the Tracker is out, hopefully the Olympus engineering team has more time on its hands to work their magic on the still cameras. Probably not this season, but next year might bring ...
  • With ultrawide lenses, there's always distortion. Rectilinear lenses preserve off-center straight lines, but they stretch and squeeze humans into weird shapes. Fisheye makes humans look more...

  • The bigger is a device, the more fragile it is. Basic physics. A flotation balloon, or anything with moving parts, won't survive the initial shock of hitting the water surface. It's not very long. ...
  • The current black boxes don't float. Redesigning them to add buoyancy would make them larger - meaning, more fragile - and you want then to survive jettisoning and the crash. And if it gets ...
  • Iridium satellites are in LEO, and they allow for two-way messaging with devices not much bigger than a cellphone. But they wouldn't be able to handle telemetry - too much bandwidth. A brief "I'm ...
  • Replied in GID treatment
    Actually, this would be a productive discussion. What makes GID so different from the "normal" psychological disorders, as to call for hormonal therapy and surgery? Historically, such approaches ...
  • They can't patent the *idea* of vaporware because of widespread prior art. But a specific implementation - sure, why not!

  • The price is usually based on the expected sales volume, so no surprise there.

  • Reminds me of mountaineering "by fair means".
