Missed this up to now, a quote from this page:
The Canon rep we spoke with claims they've narrowed the space between the micro lenses on the 60D's image sensor to create "gapless microlenses" which absorb more light and help reduce noise. While we can't give a verdict on image quality since it was a pre-production camera we were testing, we can say the 60D fared a lot better than expected at ISO 1600-3200. (See some examples of images we shot on the next page.)
Something is fishy here. The 7D is already a gapless micro lens set up.
Yap, exactly. Even the 550D's sensors has gapless microlenses, I think.
Just to clarify this:
550D same as 7D and 60D all have gapless microlens architecture. The difference (as i understood it) is: The (lowpass)filters attached to the sensor is a minor version used for 550D/t2i and a better one in 7D. 60D however uses the same Filter-solution used in 7D but uses tight to "gapless" sticking (is this the right word?) to the sensor, which itself is an improved 550D-Sensor, regarding light-sensivity.
As conclusion: In theory, 60D-Sensor (in whole) should perform better regarding noise and general performance than 7D and 550D should.
