Being a studio photographer along with shooting weddings, grad. seniors, etc. your explanation about using a light meter was totally a great example. I've used several crop sensor cameras to shoot hundreds of studio shots, and I've used full frame cameras to do the same. Same light, same f stop, same result. Sometimes gear heads can get mired in the muck and don't actually do enough photography, under various conditions, with various cameras (crop vs non cropped sensors) to understand lighting. You did a great job of explaining this to people.

Well said!! The aperture value does not change from APSC to FF. It does not change for brightness/exposure. It is multiplied by the crop factor when calculating a field of view comparable to FF. Using the same lens in an ASPC and FF cameras under the same lighting conditions set to the same exposure triangle will produce an image with the same exposure but different fields of view.
@Stephen.BinghamАй бұрын
I’m an optical engineer. I have been paid by governments to build fancy instruments for physics research… I think the key to avoiding confusion in this topic is to distinguish clearly between f-stop and aperture size (basically the physical size of the hole on the front of the camera), and to avoid the ambiguous use of just “aperture”. The amount of light collected by a camera is determined by the aperture size ONLY. Similarly, the depth of field rendered in the image is determined by the aperture size ONLY. Sensor size, focal length or f-stop make no difference to the light collected or the depth of field, for a given aperture size. For a given aperture size and field of view the total amount of light used to construct an image is independent of sensor size, focal length or f-stop. What a photographer needs to know is that in order to record the same image - same field of view and depth of field - they need to use (roughly) one stop numerically smaller f-stop on an aps-c camera than a full frame camera. This is because opening the aperture by one stop makes the aperture size the same in both cameras.

Exceptionally well explained, yes. Aperture multiplied by crop factor generates only a depth of field equivalent in relation to a full frame camera. Exposure is not affected - it stays the same between formats. It's confusing and that's why I always stress this out when I explain this to my students. You can multiply aperture value by crop factor, but realize that what you get is not an exposure value, but a full frame depth of field equivalent. And yes, your explanation is better and clearer:-).

Great commentary on this subject. I shoot full frame Nikon digital as well as Aps-c Fujifilm cameras. The depth of field effect is the only exposure difference between the two. I still occasionally use a hand held light meter in certain situations - sometimes in measuring flash exposure- and have never asked (or told) my Sekonic meter that I was using my Nikon or my Fuji. If I really think about it, I never did that with my first 35mm film camera or my TLR Yashica (or my 3-1/4 x 4-1/4 Speed Graphic) back in the 60s. The only difference might come IF the internal meter in the different camera was reading a slightly different scene due to the focal length disparity from my Nikon to Fuji in very contrast light. But that’s a different story because the meters are reacting to the TTL differences between the two.

Sounds like you’re spot on with your explanation. From my knowledge, (correct me if I’m wrong) a 50mm lens with the same aperture value on a full frame and APS-C camera will give you the same amount of bokeh and depth of field, but obviously the crop factor on the APS-C is going to impact your field of view, which is why using a 50mm EQUIVALENT lens to match the full frame field of view seems to have an impact on the depth of view and bokeh. The only way to match this would be, as you said towards the end of your video, adjust the F/stop to get the same amount of depth of field and bokeh. A landscape photographer on KZbin mentioned that when he went from Fuji APS-C to the medium format GFX 100s, his depth of field was impacted drastically and he had to focus stack images that he normally wouldn’t have done on an APS-C camera with the equivalent focal length. Great video as always. This topic drives me nuts because I know the mechanics and understand the values, but to explain it can turn into an argument at times.
@BoorayPerry Жыл бұрын
Yes. It is impossible to get the same field of view without changing the focal length or the distance from the subject and either one of those things will impact your depth of field.
@okaro65955 ай бұрын
They give entirely different images so comparing is hard. If the background is far enough and you shoot further away on APS-C then the bokeh will be same size. Depth of field also will not be similar. You would need to open the APS-C 1 to 1 1/3 f-stops more for the same depth of field. When you do the comparisons you need to specify what you want to keep unchanged. If you change the sensor size something else has to change. It can be the focal length, the distance or the subject. Photographers typically change the distance. However, when it comes to the depth of field formulas the subject is not even part of them so it changes.

However, everybody cares about capturing less light and was kinda bummed out by that, as I was debating getting a f1.4 lens for my Fujifilm or a f2.0. The f 1.4 is very expensive and I tought to myself... man if I had a full frame f2.0 would be plenty. But now that I know that light gathered is the same the lens decision is easier. Ok, the smaller sensor can be less performant in low light than a FF but still enough for me. The important thing I got out of this video was that cropping your sensor does not affect exposure. Thank you Perry for the explanation, keep it up ! :)

@okaro659529 күн бұрын
The capturing less light comes from the fact that you must use lower ISO on APS-C to control the noise. The light over the sensor is less but exposure is determined by the light intensity. Nothing changes on the lens when you use an APS-C sensor. This is why I hate when people say 50 mm becomes 80 mm. No it does not. Even worse is to say 50 mm is really 80 mm. No, 50 mm is really 50 mm.
@dennyoconnor86803 ай бұрын
It is simple physics. There is no change in depth of field for using a FF sensor or a crop frame sensor at a given mechanical F-stop ratio with the same lens, as long as nothing else is disturbed.. 1. Assume you have a Full Frame 35mm camera that has interchangeable sensors (just like lenses interchange) Set up your ruler and little figurines at various distances. 2. Pick an F-stop (lets say F4) and take a picture using the full frame sensor while leaving a bit of empty space around the figurines. Look at the ruler in the photo to see where the near and far limits of sharpness (DoF) fall on the ruler. 3. Now crop the borders of the picture with your Photoshop, or whatever, and again look at the limits of sharpness on the ruler. 4. Did they change? Of course not. Cropping the borders of the frame does not change the image left in the center. 5. Now gently replace the full frame sensor with an APS-C and take the same shot without disturbing any of the settings on the camera. Look at the near and far limits of sharpness. 4. Did they change? Of course not! Because all the smaller sensor does is mechanically crop the borders of the 35mm frame the same as Photoshop does. The central image remains unchanged. The surrounding unused light is just wasted. "But, but, but?" you sputter, I can prove mathematically that the F -stop ratio changes. Well of course you can because they are using a different focal length on the APS-C camera than on the 35mm (doh 😁) Claiming that using 1.6 ratio to calculate the "equivalent focal length" for APS-C gives you the same picture is baloney. The aspect ratio of the two lenses are different. And of course the depth of focus will be different (shrug). Carry on, gentlemen.
@thomasclark6318 ай бұрын
A related matter of confusion has to do with magnification of an aps-c lens/sensor combination, I.e. multiply the lens focal length by the crop factor and magically you get closer to your subject than you would be with the same focal length on a full frame camera. Unfortunately the laws of physics don’t allow the sensor size to change the optical characteristics of a lens. Moreover, for a crop sensor camera to produce the same field of view as a full frame camera at the same focus point the distance from that point must be increased; and of course focus distance is one of the determinants of depth of field.

DOF is determined by not the relative aperture value (like f/2), but by the absolute aperture diameter in mm because the bluring is caused by parallax between side poins of your outermost lens. So f/2 for 23mm crop lens is 11.5 mm real aprture and on FF equivalent lens is 35 mm and it will have almost same DOF on f/3 with real aperture 11.7 mm. With these settings you will get almost identical composition and DOF between crop and FF, but on FF you will use higher ISO or longer exposure because relative aperture is smaller. From the other side if your FF lens has f/1.4 you will need unrealistic f/0.93 on crop for the same bokeh.

In any case that would be unrelated to this video, and the explanation here is still completely valid.

It is important not to confuse equivalences with reality. The fact that the lens gets slower is an equivalence not reality. The comparable reality is that on APS-C you cannot raise ISO so high before the noise becomes excessive. Either way APS-C is worse in low light by the same amount. One must keep them separate and not mix and especially not use both at the same to say for example the lens gets slower and in addition you cannot raise ISO. The equivalence gives a tool to compare like what is better f/2.8 on full frame or f/2.0 on APS-C? Without the tool you get on one hand but on the other hand type of speculation. An alternative is to compare the aperture size but this works only if the fields of view are the same.

not really. If you're concerned about how bright your image looks then yes, a F4 lens on an aps-c sensor will look just as bright as an f4 on a FF sensor, but the actual amount of light reaching the sensor is less (since the area is larger). So if you compare the same field of view, eg. a aps-c 33 f1.4 and a ff 50 f1.4 they'll give you the same exposure, but the aps-c gets less light and thus gives you more noise. If your calculation is about how bright your image looks then you're correct, but if you're interested in image quality that's not the case. It'd be the same thing as saying a f1.4 lens and a f2 lens are just as good for low light since you can just pump the iso.
@solaweng3 ай бұрын
Totally agree. For an apsc sensor to get the same picture quality as a full frame (assuming same megapixel count and sensor tech), each pixel on apsc sensor needs more intense light (more light per period of time). To achieve this you will need an apsc lens with larger apature. For example, a full frame 50mm f1.8 with iso 1600 will result in similar image quality as an apsc 33mm F1.2 with iso 1000. 33mm f1.8 with iso 1600 will result in the same image with same exposure level, but with more noise (unless you use an apsc sensor that has the same pixel density as the full frame).

Of course f/1.8 is f/1.8. Neither the focal length nor the aperture actually change to anything.

Personally, I think we need to stop talking about crop factor. It confuses the masses and obviously many KZbin "teachers" don't understand it either. The size of the sensor doesn't change depth of field or exposure. Depth of field is controlled by f'stop, focal length and distance to subject. Good video, Booray.

That analogy with rain and the boxes just seems way off to me. Because there is also a time element aka duration. If it rains for say 1 hour the smaller box it actually have more water in it because the surface area is smaller so less to fill. Where as the larger box will have a much larger/wider surface area to fill as there is more water to distribute.
@BoorayPerry Жыл бұрын
Duration isn't a factor if both boxes are exposed for the same length of time. My analogy is good. :)
@williamgollatz19118 ай бұрын
The boxes (sensors) must be exactly the same size and exactly the same quality (leak the same). Because we all know camera manufacturers put the same flagship quality sensors in their aps-c cameras.

Using an aps - c sensor changes your field of view it does not change depth of field nor does it magnify the lens its the same focal length..
@BoorayPerry5 ай бұрын
It changes your depth of field if your composition is the same.
@canonlensesandcameras442510 ай бұрын
are you not wasting 40 % of light on apsc vs full frame as such your loosing ight as the image circle on full frame is aimed at the whole sensor but apsc wastes much of the light ?
@BoorayPerry10 ай бұрын
Nope. :)

Exposure is determined by the intensity of the light. The fact that you lose light at the edges does not affect the exposure.

Agree but… somehow performance of a let’s say f2.8 is better in full frame than APSC. Could it be because for same resolution you have bigger pixels and they are able to gather more light? Or manage better. There’s more dynamic range, less noise, for sure. Is the same amount of light, YES. The result is equivalent, NO. I would say is half a stop or 1 stop difference. This is why a 50mp f1.8 sensor of a mobile phone cannot beat in low light a f2.0 26mp APSC camera, for instance. Am I wrong?

The larger sensor simply rendors the light better

The physical dimension of pixels will vary. A full frame sensor is dimensionally 24mm x 36mm. If the size of the pixel is reduced more pixels will fit on the sensor. The smaller the pixel, the higher the resolution so not sure you can equate sensor to f-stop in your example.

I disagree. I have been shooting indoor basketball at a local college with a Fuji XH2s and 50-140 f2.8 (75-210 FF) at lower ISO than some people there shooting with FF and 70-200 f2.8 lenses. Shot the same games with the 40mp XH2 camera and my ISO was about the same. Maybe a stop higher. Both rendered very little noise at 3200 ISO. I don’t see major noise pop up until 6400 and even then it’s manageable. However, if I use the SOOC JPEGs with high iso NR enabled, I get clean images up to 6400 ISO.

No one is saying that an APS-C will beat a top-tier FF camera at dynamic range and noise. Bigger sensors with bigger pixels will usually outperform smaller sensors if the pixel count is the same. For me it's about value. The APS-C sensors are producing images at high ISO that are "good enough." There will always be better cameras but will they be smaller? Will they be less expensive? These factors count too. It's like, I could get a big V8 engine in my car and I would be faster but would it really be worth it?

OK, explain this: I can use my Nikon Z6 II at ISO 6400 and get fairly clean images. If I use my Panasonic GX85 with a Micro 4/3 sensor at ISO 6400, the images are very noisy. Why the difference?
@poserp Жыл бұрын
Because the "pixel pitch" is different between the two cameras. An individual pixel on the Nikon sensor is roughly double the size as that on the GX85. Hence, to really compare the two you need to shrink the GX85 pictures by 2x so that you're comparing apples to apples. This has nothing to do with the size of the sensor, rather it's the size of each pixel on the sensor. You could put pixels the size of the Nikon Z6 II on the GX85 sensor, but it'd have about 4x less of them and be 4MP in resolution rather than 16MP.

The MFT image is magnified more so noise becomes visible. Magnification always brings up errors.

"How an APS-C Crop Sensor affects F-Stop!" - It doesn't. Unless you are for some reason comparing with, or converting to, 35mm/Full-Frame equivalent. Something there is really no reason to do in 99.997959% of circumstances.
@vladtepes481 Жыл бұрын
Sensor size has no effect on the F-stop. Depth of field is, however, affected by the magnification of the image on the sensor and the chosen aperture.
