Difference in image from APS-C to FF

[JoFT]

I believe this comparison is too weak: you should consider µ43 as well. I do have 2 photos from all 3 formats in comparison:

The top is the 5D3
The middle is 7D2
The lowest is the Panasonic GM1

I will extend that comparison in the future but I think you have to do extrem stuff to get the advantage of FF, but than there is no choice, f.i. @ HDR and extreme adaptions in post...

Without knowing the specific camera settings for each shot the comparisons are useless. But the DOF apparent in the bottom group would suggest you have the labels reversed with the ff crop on the bottom and the m4/3 on the top.

Well done, lead off with the DxO overall score (which even DxO says can't be used between sensor sizes, though most would say is entirely irrelevant for any kind of comparison), then follow up with your flawed methodology comparison images that are handheld and auto focused, some in different years!

Sorry my friend, your conclusions might make sense, but your post is so rife with inaccuracies it is scary.

Thank you for your comment. My idea was to show real world comparison and not a scientific one.

For the comparison of dynamic & tonal range as well as color sensitivity shooting from a tripod will not give us a different result than handheld - due to my understanding.

If I want to make ist scientifically correct: Comparing cameras from a tripod would make an alignment of all cameras to the same optical path necessary without any influence on the conclusio... This means adapters for each cameras which I can align... And the result would be the same...

And the mixing of an old image from 2011: If I know that I have two photos were I see a certain phenomena much clearer I think I can use this image - als long as both images are taken under comparable circumstances... (Same place, same time etc...

Based on past statements, I didn't even bother clicking on the link. I can drive by a wreck on the side of the highway without slowing down to look at it, too.

Here's one big difference between APS-C & FF - the pixel density really brings out the flaws in lenses - check out the purple fringing in the 7DII vs. 1DsIII from the latest test on TDP - yikes:

Is that pixel density doing that or distance from the chart ? I presume these are shot on the same framing so the 7DII will be further away.

I think TDP is a very useful and well executed resource, but I'm not sure allowing direct comparisons between APS and FF reflects real world results.

Thank you, good sample... I have the feeling that pixel density gives a big impact.. What might work with a pixel pitch of 6,3µ may not work with 4,0µ...

The pixel of µ43 with 3,7µ is very close by. And to design a lens for just the µ43 size is much easier than for FF... The result you see in this comparison

I'm no optical expert, but I would think that the abberations would improve the closer you get towards infinity focus, so I would think it's the pixel density. I noticed this same phenomenon with my fast lenses, particularly with the 24L II and 50L when I was shooting with a crop sensor.

Yikes ! Yet another point then, to add to my list of reasons to get hold of another 5D mark one.

It is always a bit depending on the lens design. But basically you are right. Color fringing or Chromatic aberrations are an optical phenomena which is based on diffraction. Look at the Dark side of the moon cover: http://www.mirror.co.uk/news/uk-news/pink-floyds-dark-side-of-the-moon-128883

The same effect happens while focusing. The effect is just related to geometric conditions. In the sensor plane this effect has an absolute size. And as higher the pixel density is as more sensitive is this sensor against this optical failure.
