The myth! Full Frame vs Crop Sensors.

There is a very BIG difference between full frame and crop sensor and sadly theres a lot of BS out there ass well.

The kit lens doesn't project a big enough image to cover the full frame sensor. You would get vinetteing on the edges.

I'm sorry, but you're wrong at 7:15. A 50mm on a crop is nothing like a 35mm on a full-frame. How can the crop sensor be wider? It can never be wider than a full-frame. That's the whole reason why they call it a crop to begin with.

You're also wrong how a 50mm on a crop isn't like an 85mm on full frame. The fact is the field-of-view is closer to a 80mm on a full-frame. The depth-of-field will be different, but you can totally achieve similar results.

Here's an example. Take a crop camera and shoot with a 50mm at f/2.

Now take a full-frame camera and shoot at 80mm f/3.2

The 2 images will look identical.

Of course you can open up the aperture on a full-frame more to achieve a narrower depth-of-field and get a blurrier background, but to say you can't achieve the same look on aps-c is wrong. It's just that in order to achieve the same result, the aperture also needs to be opened up more.

And bigger isn't always better. A modern APS-C crop sensor camera still beats a 10 year old full-frame camera if you compare high ISO noise, dynamic range, and all those other factors you mentioned.

Charlie, I tested this out using a Sony A6000 with a E mount 55-210 and a FE G Lens 70-200 (full frame camera) both take the same size image at 200 mm focal length

Field of view and angle of view are different. Angle distortion is why people use 85mm for portraits on FF and not 35mm lenses. Crop sensor Cameras are used for bird photography so you can see a small subject larger in the Viewfinder. Getting longer lenses, 600mm on full frame sensor will give a better result than 400mm on a crop sensor camera. No free lunch. It’s a reason why FF is more expensive.

Hmm...the math is for the APS-C camera that a 50mm on a Crop Sensor Camera is like an 80mm on a Full Frame. The Pixels from a Full-Frame are larger and grab more data. The Kit lenses will not provide enough Bokeh for some shots due to the smaller F Stop of the lens (many are like f3.5). If you want Bokeh on a Crop Sensor camera get a lens that is F2.8 or wider. Anyway this issue is a waste of time to hear about as it has been beaten up for years. As a Professional Photographer I would think that you could use either system and shoot really nice photos. I do appreciate your preference for Full-Frame, but the cost difference between Full-Frame and Crop Sensor camera bodies may not be worth it for many. Spend the money on quality glass to achieve good enough results.

I think you answered a question that I had for a while.

Are you saying that a 50mm lens on a crop sensor will have an approximate same field-of-view of an 85mm lens on a full frame camera while having the approximate same perspective and depth-of-field as a 35mm lens on a full frame camera?

[jamesmgreen]

This is a super explanation for me to recommend. I've seen BIG channels make a royal meal of this with LONG vids (I never watched all of those).

[roybixby]

On Nikons a crop lens on a full frame just causes the camera to auto crop.
I prefer full frame becuse i\m a big ultrawide lens fan ... 🦘

Someone got out of the wrong side of the bed today didn't they 😉😂

[YoungBlaze]

Oh this must be one of those early April fool's joke videos right

[Toamserippa]

What this Video basically comes down to, is the often made mistake of applying crop factor to the focal length of a lens, but not to the aperture.
I think it's quite legit to say 50mm on a Cropbody is equivalent to 80mm on FF, but considering Depth of field, 50mm F1.2 for example would give you an equivalent 80mm F1.8 Image on APSC.
Also there might be a small benefit from sticking a FF Lens on APSC in Corner Image Quality, since modern RF Mount Lenses rely heavily on digital correction of distortion and vignetting present in the image corners. These corners get cropped out by the smaller APSC sensor, so there's not as much need for digital correction.

Still no reason to prefer APSC over FF if money is not a factor.

My R7 has more megapixels (30m) than my R6 (20m)?
I mainly use the R7 for wildlife, just for range

[ScreenFiends]

Great video, although I slightly disagree about pixel density. An aps-c or crop sensor camera will have a higher pixel density meaning greater flexibilty to crop in post. Yes, full frame cameras are increasing in MP size, but even then the pixel density of a crop sensor is typically higher than that of a full frame. Wether this is an advantage someone is subjective. I prefer to see them both as tools. The best thing about crop sensor cams for me is the bang-per-buck factor and typically lighter set ups. This equates to a more fun/ engaging experience in the field for me which outweighs the benefits of a full frame sensor for wildlife photography. For portraiture and video work I prefer the full frame look.

A guy without the theoretical understanding tries to debunk a myth.

[svtcontour]

Also you CAN get the same shot on a crop sensor vs full frame as far as framing. WIll be a different focal length and different aperture

[KeatsIT]

It has nothing to do with being "pro" lol. The Outdated-DSLR-Tech Canon mount you're using doesn't fit for flange distance reasons, while Mirrorless Canon RF and Sony FE mount accept both APSC and Full Frame lenses in either bodies (with vignette on FF ofc). Crop has more benefit in some situation (mainly range: aka sport / wildlife). Crop is also the default sensor size for cinema pretty much, Full Frame isn't really used much there. You can be a "pro" with m4/3 in certain situation. Don't be close-minded :)

[debbiesamsonwhite]

Just upgraded to the R5 from the T8i - bought one RF 24 to 105 but have to wait on the others. Biggest bummer is if I use the adapter for my 100 to 400 L EF lens on the R5 it automatically crops it down to 17 mega pixels. But my T8i shoots 24 mp. So will most likely be using 2 cameras until I can slowly upgrade to RF lenses.

[Aviator]

Agree 100%. APS-C is not just cropping the full frame, each pixel on the APS-C sensor gets about 50% less light which not only affects the picture quality but also makes the AF less accurate and sometimes completely unusable. Because of the smaller pixel size on the APS-C sensors, the diffraction-limit-aperture is much larger than full-frame sensors. So the photos won't be as clear as full frame when shot with a large depth of field.

[janradtke]

You seem to assume, that the identical lens is used on both the full frame and the APS-C, which is not what one would usually do. Instead one uses a 33 mm lens on the APS - sensor, which gives you the same angle of view as 50 mm on the full frame. And yes, full frame - combined with the right lenses - is slightly better in noise etc. However, the difference these days are in most cases not relevant and very few people can actually detect the difference in the final images. I scaled down from a Nikon D850 and Z7 to a Fuji XT-5 and am quite happy about a much more compact and lighter system - which still does everything I need.

[LoneJoe_hadley]

Ive seen on Youtube where aspect ration 3:2 will use the whole crop sensor. what do you think of that Wollertz?
