  • If today, this photo would probably have been taken with a smartphone and not a Leica.

  • Commented on Nikon D810 Preview preview

    I assume you're talking about the Nikon D4, the successor to the D1. The Nikon D4 is basically a fast focusing camera with high frame rate for sports photography. And because this kind of camera...

    It is crystal clear that what Nikon did was basically a slight makeup on the D800 to raise the price. The D810 would be a fairly modern camera if it was released in ... 2012!

    Nikon is truly...

    Calm down, gentlemen! Only a blind man cannot see that the "new" D810 is just a collection of relatively old technologies that other companies have been using for years in their cameras. Nikon is a...

    Lousy camera? Don't be ridiculous! The Sony A99 received the DPR's gold medal with score of 84%, what is higher than the 82% received by the D800. And unlike the Nikon D800, the A99 never suffered...

  • This is an extremely complex lens with 20 optical elements and almost 2kg weight. You can imagine that half the weight comes from the expensive optical glasses used in the lens construction. When a...

    It's amazing that many of the "new old" features of the 2014 Nikon D810 were already introduced in 2012 by Sony on the A99:
    • Electronic first-curtain shutter
    • 3.2in 1,229k-dot RGBW LCD screen
    ...

  • Okay, I get it. The lenses will be simpler to design, production costs will fall by half but consumer prices will double. Sony is a very smart company, indeed.

  • If fluorine is so good to repel drops of oil, why Nikon did not use it on the D600 sensor?

  • "With an electronic first curtain, the exposure is started by a purely electronic process (as the name implies). Some manufacturers such as Canon and Sony have used this for several years, as it...

  • Canon is making a big bet. Make no mistake, Canon must sell a lot of lens or loses money.

  • I was talking about JPEG Tone Curves / Dynamic Range, and not about high ISO performance.

  • How important is +1/3 EV here, -1/3 EV there? Nobody buys a camera like the D4S because these trifles. Who buys a D4S wants a rugged camera for action. Everything else is secondary.

  • Lies have short legs, milled aluminum bodies and red eyes.

  • I do not know why DPR gives so much importance to the method of distortion correction. The modern trend is that the bulk of the distortion be partially corrected optically, and the remainder by...

  • Canon 1Dx shoots at 12 fps in high speed mode.
    To achieve 14 fps the mirror must be locked up.

  • The maximum fps depends on mechanical limits of the mirror- shutter system, not with the performance of the AF system.
