Yet, we can’t use it with flash on any full frame camera.
This article opened talking about the great value of silent shooting on mirrorless cameras. Thus, at the fast 1/640 shutter speed above, combined with the slow readout of the electronic sensor, resulted in heavy banding across the image, essentially displaying the flicker of the light frequency as bands across the image. (50hz through most of the rest of the world).
In the United States and Canada, artificial light has a frequency of 60hz. Getting back to our wedding ceremony example, a silent electronic shutter can still be of great benefit except for one significant limitation: Banding with Silent Shutter Banding with silent shutter on Sony A7riii at 1/640Īrtificial light is not actually “constant” but has a frequency. Except for the Sony A9, you really shouldn’t be using a silent shutter for shooting fast movement. So, you can’t use silent shutter with flash. When shooting silent shutter for street photography, take a look at what it did to the bus in the background of my image: Sony A7riii silent rolling shutter distorting the bus Dpreview has an explanation of rolling shutter distortion which you can read by clicking the image: explanation of rolling shutter When photographing subjects in motion, there may be elongation or compression of the subject. The Sony A9 electronic shutter still can’t be used with flash, but the fast readout generally removes the other limitations of silent shutter.Įxcept for the Sony A9, electronic shutters will result in rolling shutter distortion when there is action or motion in the frame. At least this is true on most cameras: Of the current full frame mirrorless cameras, only the Sony A9 is equipped with much much faster readout. Read out speed is actually slower than the effect of a mechanical shutter. Modern high resolution sensors have very slow readout speeds on most current cameras.
Though we tend to think of the digital age as “instant,” an electronic sensor actually cannot be read out instantaneously. Flash sync limitations will be overcome in the future but flash cannot be used with silent shutter for now. The first issue with fully electronic shutters is that due to the design of CMOS sensors, they are incompatible with flash sync. For the most part, they can be expected to share the same limitations. For others, it also allows far more discretion when shooting candids or street photography.Īll of the current generation full frame cameras – Sony A9, Sony A7rii, Sony A7iii, Nikon Z6, Nikon Z7, and Canon R are all equipped with silent shutter capabilities. Most critically, I have used silent shutter of the Sony A7riii when shooting wedding ceremonies: the capability to shoot without any risk of interrupting the service with the noise of the shutter. (The Sony A7riii + Tamron 28-75 f/2.8 is a fantastic wedding kit). I’ve greatly benefited from the silent shutter on the Sony A7riii when shooting weddings. By fully utilizing an electronic shutter and without a mirror flapping up and down, cameras can be entirely completely silent. With all the major camera brands now producing mirrorless cameras, more people can enjoy one of the key benefits of mirrorless: silent shooting.
