Any kind of focus tracking ("AI focus" and the like) requires the camera to refocus between shots, and focusing requires the lens to be fully open.
Also, you can use your DoF test button with aperture set to something small (f/16..) to see how the image looks like when the diaphragm is closed, and you will observe that this is a lot dimmer than what you ...

I tested my cheap Canon EOS 2000D with a really slow burst mode, with continuous shooting & servo AF.
First, I selected aperture f/5.6. Then, I started shooting. The viewfinder was bright between the shots.
Then, I selected aperture f/22 and started shooting. The viewfinder was still equally bright, no change from f/5.6.
Thus, I assume this camera ...

For an SLR, moving the aperture blades will be a lot less effort than moving the mirror. So I doubt that there is a universal answer independent of camera model.

If the mirror moves between shots, the aperture probably moves as well. As you note, this would keep the viewfinder bright between shots. It's also possible they are mechanically connected, especially in older film cameras that use an aperture-control lever.
Canon T-series and Minolta Maxxum SLRs move both the mirror and aperture between shots.

dual apperture means based on the light(luminous intensity) the apperture will switch just like human eyes eg:galaxy s9, if the lux is low,low light situations like night ;it will switch to f1.5 to allow more light to the lens and in bright conditions switch to f2.4 to get vivid,bright photos.if a fixed focus camera,then only narrower area will be captured ...

Is there any reason to change the ISO manually, rather than have it set automatically?
The primary reason to set ISO, along with shutter time and aperture, manually would be to totally control exposure manually rather than let the camera set exposure. Not every scene needs to be rendered with an overall average brightness of medium gray. Left to its own ...

It isn't Manual Exposure until all 3 parameters have been set to manual: aperture, shutter time, and ISO (video gain). So in situations where you absolutely must have a defined exposure, you must also get off the auto ISO. Examples: a panorama shot where you don't want brightness jumps on the stitches due to changes in exposure, a time lapse where you don't ...

The modern camera is loaded with automation. You can elect full automatic -- now you point and compose and take the picture using the setting dictated by the camera’s software. In many cases this image will be quite satisfactory.
On the other hand, a skilled photographer might choose to reject the camera’s logic and go it alone. Now we are talking creative ...

In some cases (found it a useful way to work stage photography), it even makes sense to use ISO as the variable element in doing manual exposure. Eg in a stage lighting situation where you set the shutter to the slowest acceptable speed (so no motion blur or camera shake), set the aperture to the widest acceptable value (so you have enough DoF and not too ...

Yes, there is.
High ISO means lots of noise. Not all photographers want noisy images, although some minor amount of luma noise as opposed to chroma noise may be found pleasant.
Also, the auto-exposure of camera might not work in all cases (examples: astrophotography, photography of moon, fireworks photography, aurora borealis photography).
By setting the ...

yes for sure, High ISO values (like 1600, 3200, 6400) introduce more color noise in your picture which isn't a desired effect. So best to keep it as low as possible*
*or as close to the native ISO of your sensor, often between ISO 100 and 200.
As a photographer being used to manual exposure settings auto iso also makes it hard to over or under expose. Then ...

The first time it happened was after being out in the rain for 4-5 minutes
This, to me, suggests you may be misusing your equipment. The Canon 40mm STM lens is NOT water resistant.
The same is basically true for Canon 60D: Is the Canon 60D weather proof?
Letting the camera and lens dry thoroughly and cleaning your contacts may solve your problem. Or, it ...

The last time Camera FV-5 was updated was in November 2017. To say it is getting a bit long in the tooth is an understatement. That was only three months after the initial public release of Android 8.0. A lot of reviews for Camera FV-5 are negative and indicate that it causes a wide variety of phones to crash when certain features are accessed. It may be ...

Depends a lot on the actual camera hardware and the camera application. On my Android 9 (Xiaomi Note 7), the camera app has a "Pro" setting in which I can pick the ISO, the shutter speed and the focus[*]. You will notice that there is no setting for aperture, because since the small size of the sensor makes the camera diffraction-limited, the camera is ...

What is the effects on depth of field, when reducing the aperture?
Depth of field will increase with a smaller aperture.
signal to noise ratio
That depends on what if any other things you change.
If your original settings were correctly exposed and you reduce the aperture without changing anything else then you will underexpose the image, making your ...
