Smaller cells collect fewer photons, so they are less sensitive. They can compensate by using longer exposure times (blurrier images) or higher gain (worst signal-to-noise ratio). In general, a similiar sized sensor with fewer, but larger, cells will take photographs that are superior in every aspect except raw resolution.

It's unfortunate that camera makers use "megapixels" to hype their products to consumers, and try to pack in more and more pixels even though the image quality suffers.]]>Jan 21st 2007 11:08AMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Jan 21st 2007 11:46AMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
When will they finally start with larger, lower-resolution, lower-noise, higher dynamic range sensors? When they do, I'm buying.

I love my D200, but I want high quality PS sensors too.

Unless you're designed the PCB (printed circuit board) for this device, I don't know why they state the package size as opposed to the actual sensor size.]]>Jan 21st 2007 2:56PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
who even needs 20x24 pictures anyway...]]>Jan 21st 2007 1:41PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
I really don't know anything about Cameras but I have a hard time believing that the amount of photons the sensor picks up makes any difference. Photons are quite small and I don't think the sensors are capable of differentiating between each individual photon.

A link to your source would be nice...]]>Jan 21st 2007 2:57PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Jan 22nd 2007 1:18AMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/

It's simple principles of Digital Photography/Imaging my man........It the first thing you learn when you start to read about how a CCD sensor actually works or when your DigiPhoto Professor starts class.

Yes the photons are small......but size ISNT everything especially when it comes to Photography.]]>Jan 21st 2007 3:25PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
So, go ahead and believe the marketing hype. I have a high-mp pointandshoot and a 8mp digital SLR and for times when quality counts, I'll take my SLR any time. For pics of the kids on the go, I leave my SLR at home. Each has its place.]]>Jan 21st 2007 4:47PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Jan 21st 2007 6:46PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Jan 21st 2007 5:58PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Jan 22nd 2007 12:24AMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
And in answer to my own question regarding why they state a measurement that's larger than the sensor's width, it's because the measurement refers to the sensor's diagonal dimension (just like TVs).]]>Jan 22nd 2007 3:11AMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/
You really don't even need to compare it to barbie-cameras. A prime example is the Nikon Coolpix 8700 vs 5400. The 8700 crammed 8mp in the same sensor area as the 5400's 5mp. The noise levels on the 8700 made pictures at anything above 100 ASA total crap as compared to the equivalent picture taken with the 5400. I think it's a conspiracy between the hard drive, computer, photo software, and camera manufacturers...

I just CAN'T take pictures the way I'd like to with it. Anyway, does anyone know if the Rebel XT handles blur very well(e.g. blur from handholding the camera, subject not perfectly still, etc.)? I want a camera that will last for quite some time, and take excellent
pictures in a variety of situations. It costs 700.00USD where I am, and I don't want to buy it if it is known to break, take blurry pictures, etc. I would also like to be able to do macro photography with it so any suggestions would be appreciated.]]>Feb 4th 2007 12:37PMhttp://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/http://www.engadget.com/2007/01/21/sharp-unveils-8-28-megapixel-1-2-5-inch-ccd-sensor/Feb 4th 2007 1:11PM
