  • Oh cr@p. Dropped my TG-1 - just a couple feet, but it landed on top of an unlucky pebble, and the screen is cracked. The camera still works, but from the looks of it, it's no longer waterproof. Oh ...
  • Using a TG-1 in high-contrast scenario can be a struggle, I doubt TG-3 is much better.  At least, with TG-3 you have control over the ND filter. Shadow adjust brightens dark shadows, but adds some ...
  • Aside from what I care about (which very definitely isn't a $10,000+ camera with a fixed-everything normal lens), there's a matter of feasibility.

    Commercially, a specialized sensor that could...

  • "get the Sagittal and Tangential planes to coincide on the Petzval surface" - if I understand this correctly, a comparatively simple symmetrical lens system can correct for astigmatism, while still...

  • Sorry, this still doesn't sound convincing. Improved corner sharpness (at some apertures, at some distance settings) just does not sound important enough to warrant a separate *type* of sensor,...

  • Great Lakes ice coverage did set records. Lake Michigan, for example, set a 41-year record with 93.29 percent coverage on March 8, beating the previous record of 93.1 percent in 1977. http://www.ml ...
  • Hamas are launching *unguided* missiles towards cities.  So killing somebody is a luck of the draw.  They are stationing the launchers in densely populated areas.  By the time the airstrike ...
  • Replied in "Ever"???
    The hottest month "ever"?  I suspect there's a paleontologist or ten who might take issue with that. If you exaggerate to the point where anybody with high-school education can see you're fibbing, ...
  • Here's your large snowball: (1) Country of origin: Syria (Possibly based on Chinese WS-1 design) (2) Class: Long range artillery rocket
  • Funny how their sample image's corners are completely blurred.

    If you're showing off a great new feature, wouldn't it be nice to, you know, actually show it off?

    On a more serious note - why add...

  • The article said "In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a ...
  • Macx: Color depth refers to the number of bits per color. In terms of sensor characteristics, it's basically DR of individual color channels. MF sensors have significantly narrower DR than FF...

  • "A 24mm f/1.4 full frame lens is equivalent to a 12mm f/0.7 lens for micro four thirds. But no-one makes one so there is no equivalent to the 24mm in the real world"
    - They make a focal reducer for...

  • The problem with medium format cameras is the tiny sales volume. This means there's not a lot of money in sensor development, so their sensors are always generations behind the mainstream, and...

  • A "signal to noise ratio at each photo site" only matters if you are examining the sensor output at 100%. On the other hand, if you're comparing final images of a fixed size (for example, 13x19...

  • Camera's "comfort zone" is not just about light levels. Large sensors generally have more DR, which makes a big difference in high-contrast scenes.

  • I don't see how the mirror width would make any difference, as long as it's wide enough to show the target (I'm thinking, 1/2" in the setup that I described). If anything, it might be useful to ...
  • It's pretty far-fetched.  Trying to shoot a 1" object from 30 feet away, with vibrations introduced by fast-rotating mirrors, would be, shall we say, challenging :)
