Canon 5D Mark II Rumor Mill

There is a report in from Finland that speaks to the lack of stocks of the 5D + 24-105L kit — and it seems that B&H are also out of this combination too. Has 5D production stopped? We are anxiously awaiting the next incarnation of that marvelous 5D. (Mine was stolen and I am still fuming over it a year later!)

Canon might still be trying to incorporate EF-S lens support in their ‘low end’ FF camera…whatever that means.

Now a PDF file has surfaced mentioning a 52MP sensor. Hmmmm

“We have developed a new CMOS image sensor having pixels of more than 52M in APS-H size. The CMOS image sensor has the most number of pixels known to date without stitching. The sensitivity of the monochromatic image sensor is 39000e-/lx?s. The sensitivity of the color image sensor (green pixel) is 16600e-/lx?s. Pixel size is 3.2um x 3.2um. Random noise is 5.5e- with a saturation level of 24000e-. The CMOS image sensor has 5 x 5 random block readout mode and 4(2×2) adjacent pixels averaging mode. The reproduced image shows splendid high resolution.”

Hmmmm

Canon Xsi, 450D - 12.2mp

450D Xsi From DPreview: The EOS 450D is the balance between beginner-friendly ease of use and the manual control / customization. The new stabilized 18-55mm lens is a distinct improvement on some of Canon’s earlier kit zooms and the fact it only adds $100 to the body price is a real bonus. That said, you really need to be using primes and pro-level zoom lenses to really see what the sensor is capable of. However, the default JPEG output is too bright and contrasty and the metering sometimes gets it wrong.

The Pros
* Superb resolution, good per-pixel sharpness (especially in raw files)
* Good tonal response and dynamic range
* Trademark Canon CMOS noise free images, remain detailed even at high sensitivities
*Optional high ISO NR removes all chroma noise
* Viewfinder bigger and brighter than predecessors
* New features (live view, spot metering, MyMenu, Highlight Tone Priority, 14-bit raw) lift it above the typical ‘entry level’ and move closer to 40D territory
Improved continuous shooting, 3.5 fps and better buffering
* Feels very fast and responsive in use
* Good battery life
* Compact, sharp stabilized kit lens (though it can’t match the sensor’s superb resolving capabilities)
* ISO indication in viewfinder (finally!)
* Lots of external controls including new ISO button give instant access to commonly changed functions
* Contrast-detect focus in live view (though see cons, below)
* Bright, clear 3.0-inch screen and clear, logical menu system

The Cons
Average automatic white balance performance, still very poor under incandescent light * Limited exposure compensation range (+/- 2.0 EV)
Contrast detect AF so slow it’s useless for most types of photography
* Metering has tendency to overexpose in very bright, contrasty conditions
* Default JPEG output may be a little ‘over processed’ for some tastes (raw far more flexible)
* Flash must be up for AF assist lamp (although AF is good even in low light)
* Automatic AF point selection unpredictable (use center AF, it’s safer)
* Occasional total focus failures (in our case only 5 or 6 shots in almost 2000)
* New Auto Lighting Optimizer doesn’t really seem to do anything
* No mass storage USB support
* A little pricey
