1) I no longer believe J. Rista knows anything. I used to think he had a pretty good grasp of technical issues and would even specifically ask him about certain issues. Now, I just think he's full of himself and doubt the accuracy of anything he used to claim knowledge of.
Well, I think that's a bit harsh and extreme...but everyone is entitled to their opinion. Why would anything I've said recently invalidate things I've said in the past though, especially things I've provided the math for? Is it that you really don't trust what I've said in the past (I know you don't trust what I say now, that's beyond clear), or simply that you just want me to shut up and not voice my opinions because your simply tired of hearing them, and your at the point of flinging insults in hopes I'll respond? You really want me to shut up that bad...you could have sent me a PM.
If your that sick of it...fine. I'll be done with this thread. If you really don't want to hear me anymore, ever, on any other threads...you can ignore me in your user profile. Here...I'll make it easy for you...just plug in your user ID:
Perhaps a bit too harsh. Maybe it comes from typing at the speed of thought.
I'm just perplexed as to why this suddenly has become so all-important. And, yes, I do think it has undermined your credibility with me – not that that should matter a bit to anyone.
But, do answer me this. A few months ago, you wrote a number of long explanations as to why a new 7DII sensor could not possibly match a full frame sensor in high ISO performance. In fact, as I recall, the basic premise was that we were pretty much at the limits of physics when it comes to ISO performance and that the best that could be expected was maybe a quarter to a half of a stop or so improvement.
So, knowing that, why does there seem to be such bitter disappointment that Canon has not exceeded the limits of physics?
I've got to be honest. I've looked closely at comparisons of Canon, Nikon and Sony performance on any number of review sites. My conclusion, which has been confirmed by the reviewers in their assessments, is that the higher megapixel sensors used by Nikon and Sony have much more serious noise issues as ISO increases. When you look at the comparison shots posted on these different sites, the story is always the same, whether its full frame or APS-C -- the greater the pixel density, the greater the noise.
In fact, Sony themselves are confirming that, since they significantly ratcheted down their pixel density to get better high ISO performance. And, even Nikon has now released their new camera with fewer pixels to improve their ISO performance.
So, what has caused you to now believe Sony's sensors are magical and Canon's are an utter failure?
