Yeap! Please use the old 80 bucks lens (28-105) that i used for my own shot and then come back to tell us what you found.;-)

I have no interest in what you think of your outdated camera and cheap lens. The image quality won't come close to what I want, at any ISO or of any photographically interesting subject/scene. Your test shot merely illustrates the ugly artifacts you consider acceptable and even weirdly pleasing in the pursuit of a noise-free photo of a piece of trash.

Wow! Perhaps this thread will be locked soon.

Seems more likely to reach 150 posts, and practically all of them unnecessary. "Nick Zochias" replies are non-sequitur "contributions."

Too bad, because the original question never got a clear answer.

I beg to differ. I think the question was mostly answered with the very first reply.

The original question was whether "bigger pixels" were "less noisy". Apparently the answer is "it depends".

See the first answer to the OP. I think the caveats to that are summed up nicely here (read the entire text of this post).

Those are fine posts, and I read them when they were posted. The original question is subject to interpretation, though. See the first answer to the OP. It suggests an interpretation. The later, linked post is addressing a question not posed in the original post.

Is the original Canon EOS 1Ds "less noisy" than the 1Ds Mark iii because It has bigger pixels?

Or would the answer depend on various additional considerations?

Thank you for your comments.

My actual questions in my first post were about pixel size, pixel count and sensor size, vs noise, SEE BELOW. And at the beginning of the post I asked whether it would be possible to have any consensus concerning my questions. I tried to ask the questions as clerly as I was able to, and I got excellent answers, so anyway not much problem for the experts to give excellent, detailed answers. So thank you to everybody.  (As often is the case, the headline was not the actuall full question(s))

  1. Is it possible to generally say that FF sensors with fewer and bigger ”pixels” are/ are not, less noisy (to any practical degree) than FF sensors with smaller ”pixels”. (Same for APSC sensors)
  2. Some DPR members also dispute whether FF sensors (regardless of pixel count ?) are less noisy (better for low light photography) than smaller sensors. One argument is that the existing difference in noisiness between FF cameras and small sensor cameras basically depends on the fact that small sensor cameras have smaller lenses and thus the lens collects less light. According to this FF sensors and smaller sensors would be equally noisy?"
