  • Sensor performance should be much better on this one. Its not Just BSI its a whole new process see

  • I usually wait till the completed article till reading but thanks for this. Others on the web have done some MTF measurements and its quite startling. Samsung also has this feature on its NX20 and...

  • You left off one advantage of the 810 the electronic first curtain. This makes a bigger difference for macro and telephoto's than one would think (especially with these high pixel counts). Dpreview...

  • Does it have the electronic first curtain like the 810?

  • I was also excited to see this. I use a lot of long lenses and shutter shock starts to make a big difference from 180mm and over. Put me off the Fuji till now.

  • Actually just want to point out that the Canon is only really bad at low ISO were its off sensor ADC creates a fixed amount of noise which fills up the shadows. Once you get to ISO 3200 its just as...

  • I would point out that the special glass used that is melted in platinum crucibles isn't exactly cheap to manufacture. Neither is the micron level tolerance on the parts or the assembly or the...

  • I would point out that the special glass used that is melted in platinum crucibles or grown over the couse of the year isn't exactly cheap to manufacture. Neither is the micron level tolerance on...

  • Yes think product or studio shots which will be printed large. Even with all the light in the world m43 won't compete (not that its supposed to) with full frame. That is until such time as full...

  • Commented on Nikon D810 Preview preview

    Very little. Remeber the mechanical shutter is usally only fast enough to expose at 1/240 of a second before it needs to start closing the shutter before the the first shutter is open (the limit...

  • The shutter speed decides how long each line is exposed. So you may be rcording at 30 frames a second and the sensor is capable of recording at 240fps (possible for some but more likely 80 or 120)....

    EFC works by reseting the sensor line by line at a very quick rate so it is ready to accept a new charge. The physical shutter then closes after the reset so the pixel receives just the right...

  • Quick reply to the question above. Unity gain is only valid if there is no read noise and pixel sizes are equal. If a pixel is twice as large it could have 2 electrons when the other would only...

  • Of course the higher conversion gain is leading to less quantization error. If it didn't all sensors would capture at ISO100 and boost digitally. Since they're all 14bit and the last two bits are...

  • Probably becuase you can't use the Canon lens on the Nikon.

  • What amazes me about Lytro is that they actually deliver. I see many announcements of new technology or methods but an actual product never hits the shelf or takes years to arrive. They announce...

  • Commented on 1939: England in Color (part 3) article

    Are you usin a scanner to get this in? Have you tried photographing the negatives using a good macro? I've found it gives me much more freedom to control the curves than scanner software even...

  • Commented on Sony a6000 Review preview

    They count each red, green and blue sub-pixel as a dot. So 480k x3 becomes 1,440k and 786k x3 becomes 2,359k.

  • Commented on Samsung NX30 Review preview

    Thanks, haven't laughed that hard in weeks.

  • Initialization is much faster than readout.
