What is a leaf shutter lens?
A leaf shutter is a shutter found on some cameras, using a small number of identical overlapping metal blades, called leaves, to open and close in order to expose a photograph. It is usually placed near the iris within the camera lens. The reason is that most of these shutters have a built-in iris diaphragm.
What are the disadvantages of a leaf shutter?
Cost: Leaf shutter cameras, and particularly leaf shutter lenses, are quite expensive compared to focal-plane shutters. Since each lens has a shutter inside, lens purchases can become very costly. Leaf shutter cameras and lenses are more complex and cost more to manufacture.
Which cameras have leaf shutters?
The brand new Hasselblad X1D (or was it 1DX or D1X? 😉 ) comes to mind. This is the worlds first mirrorless MF camera system, and in every lens there is a leaf shutter.
How long does a leaf shutter last?
it will have a life expectancy more aligned with mid range DSLRs; likely around 150-200k actuations. That would be better than the life expectancy of some entry level cameras using focal plane shutters rated at 50-100k actuations.
What is simple leaf shutter?
A simple leaf shutter is a type of camera shutter consisting of a mechanism with one or more pivoting metal leaves which normally does not allow light through the lens onto the film, but which when triggered opens the shutter by moving the leaves to uncover the lens for the required time to make an exposure, then shuts …
What is the focal plane of a lens?
Definition of focal plane : a plane that is perpendicular to the axis of a lens or mirror and passes through the focus.
When the shutter speed is brief or fast the space between the focal plane shutter curtain is narrow?
If a selected exposure time is short (or fast shutter speed), second curtain “chases” first curtain across frame and exposure is through a narrow traveling slit between the two curtains. The second curtain follows so closely behind the first curtain that the entire frame could never open to light all at the same time.
