About the "same" sensors for 300D and 10D

Digital cameras Canon have really well proved among the majority of photographers,
Especially after an output of model 300D when popularity of this mark has increased many times over, due to very "democratic" price. However, there is an error, that the sensor controls established on younger model (300D) and on more senior model (10D) are identical. IT NOT SO. Here that writes itself Canon

" Like the EOS 10D, the EOS KISS DIGITAL (300D) uses a CMOS sensor having approx. 6.3 effective megapixels (out of a total of 6.5 megapixels). To reduce sensor costs, the chip size HAS BEEN MADE SMALLER without changing the image format. More sensor chips can thus be made from a single wafer. "

We have a jpeg-image of this document, and also a photo for comparison of sensor 300D and 10D in the same document. In it it is shown, that the sizes of a sensor 300D it is less than at 10D.


P.S. If it will be interesting to someone,
we can send the doc. image by e-mail.
Unfortunately, we can't insert this
document image in this topic body.

According to Canon Camera Museum both cameras use the same sensor.

From 10D description:
The model's imaging element comprises a Canon-developed 6.3-megapixel large-area (22.7 x 15.1mm effective size in a 3:2 aspect ratio)

From 300D description:
The EOS Kiss Digital incorporates a Canon-developed 6.3-megapixel large-area (22.7 x 15.1 mm effective size in a 3:2 aspect ratio)

That doesn't mean they are the same - those dimensions given are only the working area, not the total area of the silicon required to accommodate ancillary IC elements and space for connectors, etc.
If they can reduce the overall size of the blank then they can indeed get more from each silicon wafer.

Chris,

Maybe that is the case, but if so, that is really just re-packaging the same technology. When I read Cat& Mouse's email, I thought he was refering the size of the imaging component (an easy mistake to make?)

And even if electrical components have been re-positioned, that does not mean that - electrically - there is any difference to the workings of the sensor.

That makes more sense, same size actual image sensor but less peripheral space used for all the bits that make it work.

Thanks for explaining

Chris,Matthew, Bill
thanks for response.

We have already sent to Matthew all necessary information with the sensor pictures by the e-mail.

Malik & Mary.
