sensor protection

After nearly making a mistake while changing lens, I just had this thought. (I once studied usability and Human-Computer Interaction)

Why don't they design mirrorless cameras so that when you press the button on the left of the lens to detach it, it automatically switches the camera off electrically, so that the sensor doesn't attract dust etc during the lens switching.

Maybe you should try it! For one thing, there is no sensor image when pressing the lens release button.

Re: sensor protection

I hardly ever turn the camera of when changing lenses and never really have a problem.

Re: sensor protection

As the button is linked to the electronics, theres no reason I can see why they don't close the shutter while the lens is off... even more saferer.

I think Canon do that with their new full frame mirrorless camera the EOS R.

Re: sensor protection

Several of the adapted lenses I use have no position for the locking pin, so the camera still thinks the lens isn't engaged when it's fully mounted...


I'd much rather have the camera work than have it give minimal protection to the sensor. Perhaps the shoot without lens setting in the menu has some impact on how this works (I always change this from the default as soon as I get a new camera)
