This thread is about the 5DIII, that's what I was talking about. The 5DII is almost 4 years old, it would be foolish of Canon not to improve the high ISO performance and dynamic range. It just seems like those changes are inevitable. There have been a flood of people on CR in the last week because of these posts, it's annoying going through pages and pages of nonsense.
Has Canon never done anything foolish? Honestly, I've heard lots of complaints about the 5DII...and almost none about it's sensor. Excepting the new 1D X (no data yet), the 5DII has the least ISO noise and is effectively tied for the best DR. Is it a huge stretch to think they'll just re-use that sensor? I don't think so. They might make slight improvements, maybe gapless microlenses, etc., but if it ain't broke... Plus a re-use would save a lot of R&D costs...
well of course not. Canon makes incremental upgrades.
back in 2008 the 5D2 could be criticized because of its poor AF performance, sure. The sensor was the best in class.
but this does not mean that things haven't changed since.
The 5D2 has always had pattern-noise (banding) that basically make postproduction less flexible especially at ISO 800 or higher.
Sure, the quantity of noise is very good up to ISO 3200. But the quality is just not that good.
Now when the 5D2 had no competitors in terms of resolution and overall features of the sensor (considering that better sensors on a per-pixel basis had significantly lower resolution i.e. 12mp) then of course nobody complained about the sensor.
TODAY, however, there are higher resolution sensors that perform better even on a per-pixel basis.
Or anyway there are sensor with a lower resolution (but definitely more than 12mp) that perform way better in terms of DR and noise quality (some also in terms of noise quantity).
so TODAY I expect canon to deliver an outstanding sensor, just as the 5d2 sensor was originally.
The problem that I see is that Canon does not seem to care about DR that much, given that their top performing DSLR has an effective DR of 12 compared to Nikon, Pentax, Sony, Fujifilm, all with sensors well above 13 stops of DR.
Instead, given what Nikon has done with the D7000, if their D800 is as good an FF as the D7000 is an APS-C, Canon will not be a leader anymore.
I'm sure the 5D X will be an improvement (duh!), but my question is how much.
