By 1.3 stops, I believe Neuro meant the ISO performance. 1.3 stops equates to the difference between ISO 256 and ISO 100 - which is the theoretical difference between a 1.6x crop APS-C camera and FF - this is due to the 2.56 times greater surface area (read: light gathering area) of FF.That would be awesome ... I do hope 7D II will be a 1.3x crop sensorThere is a part of me that thinks Canon may differentiate the two by offering slightly fewer megapixels but better low-light performance in the 7D, as they have done with the ID-X.
That would make the 7DII a more interesting offering, from my perspective. If it can come within 1.3 stops of the 1D X (i.e., right at the theoretical difference between APS-C and FF, vs. the currently greater advantage of the 1D X), coupled with a high-density AF sensor (e.g. 41 points with 20 crosses) and improved metering, that'll be an impressive camera...
Canon may change tack, but so far they haven't once changed the size of a sensor in a DSLR line. If a camera comes out named 7D mk II, it's very likely to be 1.6x crop.
Ps - I really hope Canon resist the temptation to take their 1.6x crop sensor up to 24mp. It'll suffer from softness due to diffraction from f6.0 onwards - mount an f5.6 lens on there and you've got little in the way of options. Even the legendary 300/2.8 II with a 2x TC III will underperform, and leave you with just one aperture option if you want to attempt to utilise all of those megapixels. Leave the MP lower, and let those lower processing overheads allow them to push the hardware of the small mirror and shutter to its limits.
"Amen!" to that!
I certainly don't hope (and neither do I see there being any logic or proof) that the 7DmkII will be a 1.3x crop sensor.
But if it's noise performance is within 1.3x (one and third stops) of the 1DX (or 6D) - I would be happy
No need for 24MP, 18 is fine by me (if they're sharp). I have some great lenses for my 7D - including L glass and some awesome EF-S specific lenses.
The 1.3x day is over. Either FF or 1.6x crop for Canon. Roll on actual annoucements. The rumoured specs for the 7DmkII look spectacular!
Happy photo-shooting everyone!
