Amazing quality. Looks very similar to the performance of the 10D. ISO @ 1600 looks like ISO of the G3/G5 @ 400 (and only costing $300 more).

It is the same imaging chip and processor so I guess it isn't a huge surprise to see the same sort of pictures popping out the other end.

Actually it's NOT the same CMOS, similar but not the same. I'd expect the quality to be the same as 10D or at least very close to it, which is amazing considering this camera is only $899 (and probably will be in between 700-800 by Christmas)

They've ditched a load of the expensive buffer memory (hence the lower frame rates and smaller max picture limits), dumped a lot of the expensive construction materials (switching to the cheaper plastic body) and ditched a lot of the additional internal parts (PC ports, usb 1.1 only, etc) which all significantly reduce the component cost and bring down the assembly and testing costs a large amount too. Along with probable yield improvements on the CMOS and DIGIC its not surprising they can cut this much out of the cost and still make a profit.

I was under the impression that it was the exact same CMOS (I may be wrong).

One change I'm certain of is that what was 4 seperate pieces of circuit board (onto one of which the sensor is mounted in the 10D) have been combined into one which reduces production costs. Canon are claiming that this also serves to reduce noise even more.

Bod I have looked as well for any clear reference that this is different sensor, and have found nothing. Given this is same dimensions, same exact pixel count, I'd ve REALLY surprised if they designed new silicon... chip design being a VERY expensive process.
I would NOT be surprised if the packaging of the sensor is different; they may have found a way to reduce the cost of packaging and mounting the sensor to the card.

"The CMOS sensor found in the EOS 300D is similar to that found in the EOS 10D. The manufacturing process is slightly different, but the quality output between the two devices is essentially the same. The three-layer optical low pass filter and IR cut filter are identical to those found on the EOS 10D, where they have proven highly effective. "

Depending on if the buffer memories are integrated, they may just have done a respin with reduced memories, so essentially the same sensor with different peripherals. Also the ISO is changed so again, it could just be a minor derivative change - small size/ less memory cuts costs by area, by yield improvements, and reduced testing time per part. For a large enough run, its probably worth the additional million dollars or so that a new set of masks cost.

I´m planing to buy this camera when its out. I guess its not a bad buy at all, but does anyone know any issue with it that might be annoying?
Like other EF lenses will work but the image quality will be much less than with the standard lens attached, or some feature wont work with other lenses than the standard. etc...

As you cant use regular AA batteries(?) I wonder what the power consumption is on this camera, I guess it should be about the same as the 10D, so for how long can you 10D owner´s shoot pictures before you have to recharge the batteries?

It will be Hard to wait until the price goes down abit, wonder if I can make it?! =)

Oops, if i´ve browsed the forum abit longer I would have found the answer on my questions right away... 8|

For some reason it doesn't have a spot meter, that could deter some people but not me. I think the new wide angle lense that comes with it and the zoom lense will be quite good. I don't think I would have a problem with either of them because they were made for the camera and Canon have adressed the issues of chromatic distortion and color fringing with improved lense coatings. Probably not the fanciest lenses but far from the worst either. As far as issues of use. With my 35 mm Rebel I really like the control dial on the top left with the LCD panel on the top right as they seam easier for me to see and use in those positions. But it is a minor thing that would just take some getting used to. All in all it looks very good to me. For my use which isn't particularily rugged I'm willing to give up some durabilty and features of the 10D for a lighter weight camera.
