CF 3-10 plays into this. The top wheel now lets me select R out, R inside, L inside, L out, with the Quick Dial doing the vertical selection. I thought one of the reviews mentioned being able to do an "all around the racetrack" selection.
I recived mine today and it doesnt work i get error 99 every time.....to hell with Canon and its quality control...at least 16-35mm mkII seems to work...
That was the reason Tallyn gave me for being behind on their orders! They said that canon is maybe having to test everyone before sending them out..after getting these returns...but that was just a guess..sign
Does anyone know if the 1D MIII is able to produce high ISO, low noise images because the sensor actually produces less noise, or because of better noise reduction/removal as part of the processing?
yeah, P.A, that was their speculation anway, he said they have only recieved 4 and don't know what the problem is..He said he would understand If I decide to cancel, might be better playing the B&H lottery, but not burning any bridges!
The twin processors help, but I think the new sensor design is the main reason. (smaller pixel pitch and reduced gap between microlenses)
BTW, the high ISO noise reduction CF only takes care of color noise.

Well I for one sure as hell hope they test each $4500 camera before they send it out.
The bigger micro lenses make up for the smaller pixels, relative to the 1D2 sensor. I seem to recall reading recently that the 1D3 has a different amplifier setup in the sensor so there is better NR there. Plus of course the ex-sensor processing.
The NR mode is a great feature but apparently it gobbles up the available buffer space to a great extent. That's disappointing for sports and action shooters.

While the pixels are smaller on the 1D-3, the actual LIGHT-GATHERING area of each pixel is identical in size to that on the 1D-2. (How? Canon shrunk the size of the elecronics that take up the rest of the pixel area that isn't actually gathering light).
That alone should mean that the noise level of the two cameras is identical between the two cameras, in spite of smaller "pixel" size on the 1D-3.
However, the larger microlenses actually gather MORE light for the 1D-3, which IMPROVES the signal-noise ratio of the 1D-3 relative to the 1D-2.
There are other electronic improvements too. I believe they mention the amplifiers being better.
The stuff in the Canon white paper we skim over covers some of these non-feature improvements.

You seem to have misinterpreted what you've read. The microlenses are not physically larger. The microlens on a 1DII/N is 7.6 microns across, while on the 1DIII the microlens is only 6.9 microns across. So the microlenses on the 1DIII are smaller, and thus don't gather "MORE light," but they have a higher ratio of microlens to photodiode area, which is where a lot of the light gathering efficiency increase comes in.
Here's a great link from RG's site discussing the 1D3. Rob got a chance to head over to Canon Tokyo and talk to various Canon-heads who work there.
The following is a quote taken directly from the previously mentioned article:
The improved high-ISO image quality, cleaner, more natural shadow rendering and resulting broader dynamic range of the EOS-1D Mark III isn't the result of a radical new Canon CMOS sensor design. Rather, it's the sum of a number of small, evolutionary changes:
* At 7.2µm square, the pixel pitch of the EOS-1D Mark III's sensor is identical to the EOS-1Ds Mark II. But the gap between microlenses has been reduced to 0.3µm in the new model, from 0.6µm in the EOS-1Ds Mark II, which translates to the EOS-1D Mark III's pixels having about the same light gathering area as the EOS-1D Mark II or EOS-1D Mark II N, despite the latter two cameras having a pixel pitch of 8.2µm square.
* Each pixel's amplifier has been enlarged; this has helped to reduce dark current noise in the EOS-1D Mark III by a factor of 1.33X, relative to the EOS-1D Mark II/EOS-1D Mark II N.
* Banding noise in the EOS-1D Mark III has been lowered by the equivalent of one stop, also relative to the EOS-1D Mark II/EOS-1D Mark II N. This has been achieved largely through improvements in the camera's firmware.
* New noise reduction routines are employed in the EOS-1D Mark III's twin DIGIC III processors.
* The EOS-1D Mark III is the first Canon digital SLR to employ 14-bit analog-to-digital conversion, up from 12-bit in previous models. This means the maximum number of tone steps possible in a RAW CR2 jumps from 4096 to 16,384. This is a contributing factor in the camera's smoother shadow gradations, though not the only factor....Show more →
