« on: September 18, 2012, 09:21:34 AM »Sadly, you aren't going to get a revolution in high ISO noise performance in a crop sensor for a very long time... if ever. With current sensor technology there is a limit to how well a crop sensor can handle noise... and with consumers for this category demanding features in video, hdr, etc... there is even less hope for sensor improvement.
But keep dreaming... it never hurts to dream.
There has already been a revolution in crop sensor high ISO noise. It's called the D800. The pixel pitch of it's sensor is VERY close to that of the 7D.
4.88µm v 4.3µm - that's only 13.5% difference. For comparison the 5D Mark III has a pixel pitch of 6.5µm - 50% bigger.
You can't tell me that the D800 doesn't have low high ISO noise. It's very competitive with the 5DIII.
However, the D800 does not do 8 or 10FPS. A crop camera is the best/only way of optimizing the following combination of attributes (1) lower price, (2) higher frame rate and (3) smaller pixels (i.e., lots of "pixels per feather"). I currently own a 5D3 and 7D both of which were purchased in the last 6 months. (They replaced a 5D and 40D.) The 7D is used almost exclusively outdoors in comparatively good light with longer lenses to photograph things that move rapidly and unexpectedly. The 5D3 is used for everything else.
