It's one of those things (sensor size) about as important as brands, or cameras that still have mirrors, or shooting in RAW, people will fight to the death over the topic for no relevant purpose.

Sure there's a purpose: MUST expound on my opinion.
Might not be relevant, but it's still a purpose.

I said you cut and pasted it -- you did.
I said you failed to reference it -- also correct.
There are no assumptions there. I referenced it.

Here are some that I can link, read these if you care:

https://www.studiobinder.com/blog/full-frame-vs-aps-c-crop-factor/

And FYI, I have been doing this for over 48 years as a worldwide award winning pro, and also as a longtime Professor of Photography at a state university who has taught the physics , advantages and disadvantages of each format to my hundreds of students. I do have my Masters Degree in Digital Photography, so I do know something about this subject. LOL

I have used both APS-C and Fullframe cameras from Nikon, Canon and Sony and have made great shots with each.

IMHO the IQ of fullframe cameras is superior in detail and ultimate resolution, detail, dynamic range, bokeh, and depth of field over APS-C.

But you can make your own decisions which system suits you and works best for you based on a host of other practical features.

For IQ I will stick to Fullframe

Cheers

Then why did you cut and paste an article with faulty information in it?

There are actually a host of different points of view by respected "experts" in the photo world. I posted a few that do show that difference of opinion.

Constant advances in sensor tech and sensor quality render any hard fast "absolutes" as moot points. This is a moving target and there is NO one correct answer anymore here. It is constantly changing.

There are APS-C sensors, notably from Fuji ,that do approach some fullframe sensors in IQ. And there are some of the latest flagship fullframe sensors that are far beyond what any APS-C can achieve in IQ.

You can choose to believe any of them or believe what you think is correct. You characterized it as conflicting information, I did not. It is all changing and the physics is being pushed by the sensor makers.

Cheers

So did you even read what you cut and pasted? I'm not talking about opinions or different points of view I'm talking about facts -- about getting facts straight. In the article you cut and pasted the author presents false information (not opinions) and later presents conflicting info. Here's an example:

Two quotes from the article follow.

1. "For instance, if you shoot a bird at 100mm on a full frame vs crop (APS-C) camera, the APS-C photo will look tighter. This is because the smaller sensor captures a smaller portion of the scene. Note that the focal length of your lens doesn’t experience any real shift. Nor does the depth of field or the lens speed change. The only real change is a field of view, which makes your lenses appear longer."

2."Finally, because of the way the crop factor works, it’s easier to achieve a deeper depth of field with APS-C cameras. If you want to get the entire scene sharp, you won’t have to stop down as much–which is fantastic for shooting in low light scenarios."

I like what you said about advances in sensor tech etc... making a hard fast comparison tough. The techie experts here can battle it out for a still undetermined # of pages... I will say this though, I DO like the idea of carrying at least one of each format. i.e. a 60D as well as a 6D in my case, utilizing top shelf EF lenses. I like the idea of mixing and matching while cutting back on the ACTUAL # of lenses needed... I could not care less on the # of pixels lost on the crop... The IQ of my two cameras mentioned above using the same lens is negligible in most situations. In fact I have (2) 60D as well as 6D. Nearly identical look, feel, and controls. Everyone has to work out there own system based on their needs. Just food for thought... What, 100mm macro not quite right, lets make it an apparent 160mm macro... Easy Peasy.

Your math is wrong.

The Canon 1.6x crop factor is applied to the focal length, as in: 50mm x 1.6 = 80mm equivalent focal length. The crop-factor is not an easy relative percentage of the two sensor sizes. It's 'easy use' is as focal length multiplier.

To use your 37% observation correctly, we'd take the total area of the Canon crop sensor 22.3mm × 14.9mm and divide that result by the total area of the full frame 24mm x 36mm, or 332 sq mm / 864 sq mm, an area actually about 38.5% of the larger frame size.

Moreover, the crop factor is the ratio of the diagonals of the two frame sizes. And, the diagonal requires taking the square-root of adding the square of the length to the square of the width, see Pythagorean theorem. The ratio of the two total areas is close, if you just use the rounded whole numbers.

Essentially the same as what I did by indicating the length and width are reduced by 1/1.6 each, which reduces the area to 39%.

"If your sensor throws away 50% of the frame, how will you ever achieve your potential as a photographer?"

Paul, many professional photographers use cropped sensor cameras with full frame lenses. They seem to be very comfortable.

Diligence is the mother of good luck. Having a cropped-sensor camera is like dating your cousin.

Take a look at some lens simulators. They might show what you want - or maybe not.

I am wondering how a crop sensor image would compare with the same image taken with the same lens and distance on a full frame camera, manually cropped to the same extent. Does that result in the same resolution and IQ?


The comparative pixel densities or pixel pitch or pixel size of the sensors will be the most defining factors here.
