Do DSLR cameras take good video?

The reason that DSLR cameras do some video is that the sensor has very high sensitivity – approximately 5 stops from the sensor’s resolution at full magnification for 1080p/30fps or 20 stops from the sensor’s resolution at 2160p/45fps. This means that you won’t see much chroma noise, and that video is very well corrected and sharp.

How to Reduce Camera Shake - 6 Techniques
Some other interesting points:

– The sensor is more stable when the focus is fast and the shutter is closed

– If you set the camera focus with a shutter speed larger than the shutter speed that you typically use, you will also see a reduction in the light that reaches the sensor, which helps your camera achieve a tighter focus ring.

– The shutter release button on cameras that support it is the most sensitive feature, and can sometimes cause the camera to lock up or to have slight problems when shooting video. Try changing the way that you release the shutter – for example, moving your hand more in front of you and moving the camera a bit more from your body. If that also takes a little longer, try increasing the shutter size (you can use the camera’s exposure button to change the shutter speed).

– When the exposure is high – such as with a moving subject – the sensor may not be able to record as much light as it would if the focus was controlled more slowly.

– In some cases the noise will be a little more noticeable as well.

DV: What is the focus ring like? Is it smooth, and does it shift with the focus? Does it move?

The focus ring moves with the camera. The ring moves up and down as you move the camera, and because you have to keep the camera focused for the duration of the recording, the ring will usually stay level, but there will always be a little bit of movement in there.

This also means that you won’t be able to use the focus ring to move the camera quickly when shooting video. Also, if the camera focus ring is not exactly level, you may not be able to focus the camera while shooting video while the focus is still set to something.

Some other interesting points:

– The focusing ring will keep changing if you change it the size while it is moving down or up. You can press down on one of the four sides when the focus is centered to set the focus again, and press back up on that side to remove the new focus.
