  • Cinch an uncinch those rubber-clad leg locks a few dozen times during the day and your palms will feel like they've been worked-over with course sandpaper. Reminds me of a Gitzo I once had. "Give...

  • Sony thought the same thing and look what's happened to their electronic's market.

  • It's like a store proclaiming 70% off! Well, if you are making margin at a 70% discount, what the heck were you making when it was at its normal price? Overcharging opens the door faster to...

  • Yes, grinding spherical optics can be cheaper today, but don't believe that all of this mass produced stuff is acceptable, some of the cheap stuff is horrifically bad, especially binoculars. Also,...

  • No, you can build a lens better, and smaller by eliminating AF. Look at Leica lenses. Fragile motors and electronics do not match machined aluminum parts that make-up a good manual lens, unless...

  • A company named TeleVue produced in the 80's a telescope eyepiece with an 82 deg. apparent field. Then, a company called Meade Instruments produced its own widefield eyepiece that improved on the...

  • Commented on Hands-on with the Pentax K-3 II article

    What I mean by "work as well" is that unlike Olympus's current true resolution increase mode, Pentax's pixel-shift mode may not require a tripod, it may be possible to capture it like an HDR mode...

  • Commented on Hands-on with the Pentax K-3 II article

    The only on-camera flash that avoids shadows is the one on the Q because it's on a little stalk that keeps the lens out of the firing line. Unless you shoot at 6400 ISO or more, an on-camera flash...

  • Commented on Sony SLT-A77 II Review preview

    I've seen weird things like this before. Like noticeable DOF differences when using different old manual 50mm lenses at the same aperture on the same camera.

  • Commented on Hands-on with the Pentax K-3 II article

    A review of the D810 would be naked without an explanation of the main reason for the D810; repairing the focus problems of the D800 series. But Nikon likely won't tell anyone exactly what they...

  • Commented on Sony SLT-A77 II Review preview

    Side issue; Sigma artificially stopping down the lens (somehow) to achieve greater sharpness at the expense of light though-put? That's a trick.

  • Commented on Sony SLT-A77 II Review preview

    Maybe I'm missing something about how this camera works (translucent mirror) but you will never get class-leading high ISO (or any other leading ISO) as long as part of the light is lost because of...

  • Commented on Hands-on with the Pentax K-3 II article

    The K3 has always been the best-looking DX camera going. The back-light colour of its top-plate LCD is terrific.

  • Commented on Sony SLT-A77 II Review preview

    There have been a lot of posts in forums attempting to link resolution with sharpness.
    For those struggling with the idea of resolution not being inextricably linked to sharpness, this review...

    I guess Hell finally froze over? :)

  • Commented on Hands-on with the Pentax K-3 II article

    The pixel-shifting is a good idea, might even work as well hand-held as Olympus's HDR mode, but it's definitely not as good as being able to call up 50mp+ resolution.

    The Japanese with their cars caused that, the soft, mushy shape of most of their sedans. Ruined the look of American cars that decided to ape them.

  • Commented on Hands-on with the Pentax K-3 II article

    What they should do is make a small, conformable flash that could sit on the hotshoe all the time. It's not that hard.

  • "f0.10" (difference) is "incredibly important?"  Too whom?
  • Terrific photos. I see some Canon FF shooters are still using the 14-24mm AF Nikon on their bodies.
