Question: So who makes the worlds highest resolution full frame 35mm DSLR now!?
Its not Canon or Nikon!.!.!.!.!.!.!.!.it is CMOS, the number is 24!.6mpWww@QuestionHome@Com

Sony has the A900 which is 24!.6mp!. Wait another 3 months and that will be blown out of the water!. Really going from 20 to 24!.6 isnt going to be noticable!. Www@QuestionHome@Com

Megapixels is only important to a certain number after that too many in the same area can actually harm image quality!. The only way to put more pixels in the same area is to make them ( the photo detectors )smaller ( though some folks say they have more pixels than they actually do by interpolating pixels for a higher count) !. After a point it dimishes the light reaching the photodetector which results in less quality, lower geometrical accuracy , higher noise and lower dynamic range!. A recent article in Digital photopro said "The number of electrons that can be held by an individual photodetector (which is measured as an electrical voltage) determines the definition of “full” in the context of that photodetector (this is referred to as a measure of “full well”)!. The larger the photodetector, the more electrons it can fit, and thus the stronger electrical charge it can record!. The minimum charge (ostensibly, no charge at all) compared with the maximum charge provides a measure of the dynamic range of each individual photodetector—the darkest and brightest values each photodetector can measure "

Noise is often caused by low signal strength!. You increase the signal by increasing the amount of light that strikes each sensor photosite!. This can be done by using faster lenses or larger sensors with larger photosites!. Or by only shooting photos in broad daylight where there are plenty of photons to go around!. Thats why I say more pixels can lead to more noise as again less light gets to each photosensor!.

Other things that are important in deciding quality is how are the pixels arrainged also called sensor architecture!. !. Are they one layer on top of each other like in a Foveon X3 or are they mosaic bayer array !? Most cameras use so-called Bayer array interpolation, where each sensor pixel has a red, green or blue filter in front of it (the exact proportions are actually 25%, 50% and 25% as the human eye is more sensitive to green)!. An interpolation algorithm reconstructs the three color values from adjoining pixels, thus invariably leading to a loss of sharpness and sometimes to color artifacts like moiré patterns!. The demosicing software in the image processor determines how much this impacts output!. Bur reguardless a "6 megapixel sensor" in a Bayer Array has in reality only 1!.5-2 million true color pixels!.

Foveon makes a sensor that has three photosites stacked vertically in the same location on top of each other!. This theoretically yields more accurate colors and sharper images!. Foveon originally took the high road and called their sensor with 3x3 million photosites a 3MP sensor, but unfortunately they were forced to align themselves with the misleading megapixel ratings used by Bayer sensors!. While I am a Nikon person I have to give Sigma credit for using the Foveon sensor!. The main downside to the Foveon sensor is its relatively low-light sensitivity!. IF they overcome that it will be worth looking at!.

Pixels shape in the array is also important!. Fuji introduced octagonal pixels in place of the square ones usually used when they made thier "Super CCD "!. They argue that the distance between pixels is smaller so they get better images!. However, the information has to be converted to a digital image with square pixels!. This results in 6 megapixel Super CCD images that are based on the measurement by only 3 million effective pixels, so the other pixels have to be interpolated!.

In an awful lot of ways pixel count is a shell game used by marketers!. And the race for higher pixel count may actually have slowed other more important sensor technology improvements!. Sensor size, image processors, firmware for demosaicing and interpreting sensor data, each pixels dynamic range all are things we should be looking at along with or in some cases after a point in place of megapixel count!.

Or to put it another way ( though I usually don't like car analogies and may regret doing this ) the old V12 used by Jaguar was only about 350 cu inches but it still could take any stock V 8 400 cu inch engine of the day off the line even thought the 400 cu inch engine had more cubic inches!.

Added:Cannon and Nikon chose to put the vibration reduction in the lens rather than the body!. Somefolks put it in the camera and make of that!. Yes that means you get stabilization only on lenses with that feature built in!. In the body in theory it would work on every lens!. But in fact image stbilization in the lens has proved to work faster and smoother with a lower impact on focus times than image stabilization in the body/ One problem with in body stabilization comes from the fact that the sensor would have to move different amounts for different focal lengths!. A canon white paper says an in body system would have to move the sensor 1/4 inch to account for movement on a 300 mm lens!.Www@QuestionHome@Com

The A900, which hasn't been released yet, is the highest resolution full frame digital SLR!. They make medium format cameras, that has 39 megapixels, which i'm sure would be much better than any mid-range Sony camera at best!. also, the A900's 24 megapixels doesn't make it the best full frame on the market!. Megapixels aren't the only things which are important in your camera- and don't make up image quality!.

The Canon EOS 1ds Mark III's image quality would far outshine that Sony camera, it's thousands more, and is a professional level body:

Haha!. We all heard about the Sony with wonder!. Now all we really have to ask is what do we do with the 24!.6 mega-pixels!. Not enough to print a billboard at full view (and most of us don't print billboards) way more than you need for normal stuff!. And they forget to mention you'll need to buy a couple of new hard-disks and a new computer system to be able to process those images with reasonable ease!. Well, I think I'd rather invest in a professional body and some glass!.Www@QuestionHome@Com

Its not the sensor that Makes the Sony A900 great, its the built in image stabilization that makes all the difference!. No need to rebuy all your lenses to get image stablization when every piece of glass you own is not IS on the A900!.Www@QuestionHome@Com

Sony!. Now, how many lenses does Sony offer for that camera!?Www@QuestionHome@Com

That is not a question, why post it!?
Showing off!?
I could Google trivia and post it too, but I have a life!.!.!.Www@QuestionHome@Com

that was a tough questionWww@QuestionHome@Com

24!.6 MB might have four times the MB of say a decent Nikon or Canon!. However, pixels go not only from left to right, but also from top to bottom!. So a 24!.6 MB camera is only twice as 'good' as a 6 MB camera!.

However, if you use a film camera and scan the negatives with a good film scanner you will have images of a much, much higher resolution!.Www@QuestionHome@Com
