I don't know, but the noise levels I'm getting in my images @ ISO 100 seem too high. The camera has nice high-iso performance as far as noise goes, but at low ISOs, it seems to have a lot more noise then what my digital rebel was throwing into images.
Here's an example:
|IMAGE IS A REDIRECT OR MISSING!|
HTTP response: NOT FOUND | MIME changed to 'image/png'
That shot was @ ISO100, and it's full of noise, look at the green areas above the fly.
I shoot in raw, and sharpen in post-processing. I don't think my post processing is introducing the noise, I basically do the same post processing I have always done with my 300D, but my 5D files are coming out with a lot more noise @ ISO 100.
I was told before that perhaps my raw converter is the one to blame, but I have tried both Rawshooter and ACR but both seem to produce noisy images @ ISO 100.
The majority of my work goes on stock photography websites to earn me some money, and they are sometimes rejecting my images saying they contain too much noise to be used. My 300D images were never rejected for having too much noise.
Am I being too critical? Are those noise levels acceptable for ISO 100? Is it normal to have to run neatimage on all images?
