If we are correcting grammar, it probably should be spelled out, one for the grammar police. :)

Nige has eloquently written about all the thoughts I have when it comes to deciding between the T1i vs. D5000. Best of all, he has helped me take a step further in the right direction.

Thanks Nige!

PS Sproutey, it is obvious you are the one who choked.

raw is not intended for consumers.

if these are targeted for consumer market, then the 16mp raw file of canon 500d is photoshop/hardrive-unfriendly.” canon could have added sraw feature from its midrange dslr family and up. nikon is arguably right on the money with 10-12mp raw file size. its the sweet spot for the entry & advanced post-processing. shame on canon for having a 16mp but very big raw file sizes for CONSUMERS without any flexibility to its raw file size.

Actually this is bad news for the Nikon, according to DXOMark itself:

Noise measurements in RAW format are indicative of pixel performance, but the viewing conditions of the image must also be taken into account. To compare prints on a given format of cameras with different resolutions, it is more suitable to compute the equivalent SNR of a camera with a given reference resolution. For equal, normalized SNR, a high-resolution camera is still better than a low-resolution camera. While it is always possible to simulate a low-resolution camera using a higher resolution camera (since downsampling is easy), it is not possible to simulate a high-resolution camera from a lower resolution one other than by interpolating or inventing data.[/quote]

Bottomline, the 500D sensor is better since it is either equal or close to the D5000 sensor even with smaller photosites plus 3 more MP.

That would be one big pixel.

Dxo is interesting: applying a numerical rating to sensor performance. I think it is worthwhile to qualitatively compare sensor characteristics, but the numerical ratings are pointless. Their findings should be backed up with real life examples where you can see a difference, otherwise it’s purely academic.

On a separate note: Canon, get your act together.

I think 10 to 12 is a great nuber (although an 8MP FF would be aawwssoooommme)!

Ditto in some spots, not so mutch in others.
