You mentioned that I shall attribute the noisier image to 7D. How does that relate to my inability to size images?
Most people drop images in PS and zoom to 100% forgetting that higher MP images are magnified more at "100%".
Of course, it will be affected by my alleged inability to compare images, but then that is just your guess, isn't it?
You are correct that I am guessing as to why you believe the 7D is noisier when reproducible tests say otherwise.
I don't objectively test cameras or formats so all the parameters you mentioned are moot.
No, your opinion is by your own admission moot.
It simply amazes me how people will stubbornly cling to opinions even when they fully admit their opinions are not based in any way on anything objective, reproducible, or reasonable. No wonder Zack went on his rant. I'm behind him 100%.
Yes, I know it isn't the same ratio of enlargement. Who cares?
Now I have no need to guess.
So what are you trying to prove through your offensive statements,
Pointing out the truth is offensive? But it's not offensive at all when people appeal to hyperbole to prop up clearly false statements?
and uneducated "guesses"?
My guess was spot on as you just admitted.
Put less stock in theories and calculations, and rely on your eyes.
Silly statement considering I'm telling you to rely on your eyes with a proper comparison.
Human nature just amazes me sometimes...
As unfocused stated in a different context- you let your keyboard run off before your brain and now you have to keep it up... (paraphrasing)
1. I did not drop images into PS and zoom to 100%. As I clearly stated before, I set the image full screen on a 24" monitor to see how it looks. Being higher resolution, the 7D gains an advantage in terms of pixel downsampling, but being a smaller sensor, it has the disadvantage of enlargement. Regardless, if one is trying to gauge whether his photos look good and presentable, all that matters is looking at them at the same size that your viewers will be looking. For me, that is either a 24" monitor or an 8x10 print. For someone comparing a 7D and a 5Dc, comparing them with similar enlargement of pixel makes sense. But I never owned both cameras at the same time. Which brings me to my second point.
2. My comments about the 7D noise is not an opinion, it is an observation. I owned the 7D and loved it except when I needed to use it at high ISOs. I could not use it at ISO 3200 and above, ISO 1600 was best avoided and ISO 800 was borderline. Not an opinion, an observation at the extremely low performance bar that full screen images from 7D showed unacceptable noise. I have frequently lamented that fact, and still I stuck with the camera for all the other attributes and the great and inexpensive EF-S lenses. So I have no idea why you are blowing this whole issue up as appealing to hyperbole to prop up clearly false statements. What would be my reason for doing that? Being able to keep the 7D would have saved me a lot of money. In fact, I tried to wait for 7DII but it took too long and I just went for the 5DIII. The difference was immediately apparent.
So, why the comment about 7D vs 5Dc? I own the 5Dc now, and had considered selling it after a small job, but I realized that I was able to use images at ISO 1600 without any problem. So, given my subjective scenario, saying 'my 7D was worse than my 5Dc" makes sense.
3. Your guess was I don't know how to compare images. Well, as a scientist, I have published my work that included various images of neurons, that needed to be counted and examined for shape and form. These were fluorescent microscopy images taken using various microscopes and magnifications. I am fortunate that the expert reviewers that accepted my work for publication didn't share your view!
Now, less cross-examine your rants:
4. You still haven't cited any "reproducible" tests or shown any of your own images. You really expect someone to comment on those low-res images without any ISO information? If you're so convinced, why not post some of your OWN 7D images at ISO 1600 without any de-noising. Let everyone see for themselves?
5. You stated one guess at the beginning at the post (PS>100%, etc) and when I said I used a different way to compare, you concluded that supports your guess.
6. Zack Arias is essentially speaking about APS-C sensors that perform better, and not having used Fuji I am willing to take his word for it. I am not saying APS-C sensors cannot be good. In fact, I mentioned he is partially correct in my first post. The reason I got irritated by the video is the weird argument that FF vs APS-C is negligible because they are both so much smaller than MF etc. So you wouldn't care if your arm broke vs it got twisted just because they are so much better than your arm getting ripped off? That's terrible logic. And he is annoying and obnoxious. But he feels like a sweetheart compared to you. I made a subjective comment, stating my observation with my own camera. And you keep trying to prove that I have an 'opinion' against the 7D based on 'what? certainly couldn't be the reviewers who unanimously praise it's high ISO performance'. It is not the words you say that are offensive (well they are, but I don't care), it is the nature of your argument- how you are making a normal, civil discussion into a fight.
7. I am surprised human nature sometimes amazes you. It should always amaze you, considering how foreign it should feel...
Say what you want to say to this... I am not going to waste any more of my time responding to your posts.
