Hi!

I´m looking for the exact CMOS chip specs of the EOS D60 chip. I would like to use the D60 for astrophotography and so i´d like to know a bit about noise, readout noise and so on.

thx

I believe that the D60's CMOS sensor is an in-house product developed by Canon for use only in their EOS D60, and it is not sold on the open market and there is no data sheet for it beyond what the D60 owner's manual says. I'd love to be proved wrong, but I haven't seen anything yet to the contrary.

Canon was the first to put a CMOS sensor in a "high quality" camera and I believe they have done some clever tricks to reduce noise that the earlier cheap-camera CMOS sensors were plagued with. Possibly related to these tricks, you may observe that on high-resolution test pattern images, there are spurious pixels visible in the image (black where it should be a uniform white, and vice-versa). For example look at http://www.dpreview.com/reviews/canoneosd60/page17.asp under the subheading "Strange Dots"

i have it..........click on this link below. then click on the PDF icon at the bottom.
you can also download the PDF from there.
if it doesn't work for some reason, just go to www.st.com.........enter stv0672 into the search box and that will also bring up the info.
pretty interesting reading i might add.

then enter stv0672 in the search box and it will give you the page where you can read the PDF file or download it.

Clearly, the stv0672 isn't the CMOS sensor in the D60. In fact, it's not a CMOS sensor at all. It's an all-in-one image processor/USB interface that accepts image data from CMOS devices. The second paragraph in the PDF file indicates that it operates at a maximum resolution of 640 x 480 pixels.

This is the kind of low-cost/low-quality image sensor found in QuickCam type devices and digital cameras costing less than $100.

Is it just me, or did this Jason guy come across like a didactic ass?

Hey Hawkeye another member has insulted you are you going to cry to Pekka to get PC Plod removed as well.
