What is a leaf shutter? - Photography Stack Exchange
2016年6月6日 · No leaf shutter provides nearly that high a shutter speed. The trick here is that a focal plan shutter doesn't fully open and close during that time. On a focal plane shutter, the maximum flash sync speed is typically much lower than the maximum marked speed--typically around 1/250 th of a second on a current shutter (but as high as 1/350 th in ...
What is the difference in purpose between a focal plane shutter …
Barrel lenses without a leaf shutter can be used with a Speed Graphic. The focal plane shutter is used for speed, specifically faster shutter speeds, thus the name Speed Graphic. But the camera was certainly not speedy in terms of shot to shot intervals and the operation of the FP shutter took longer to manually reset the FP curtain between ...
How is uniform exposure achieved when using a leaf shutter?
2021年12月16日 · The leaf shutter is in the spatial Fourier plane of the lens. The shape of the aperture with time as it opens and closes will expose different spatial frequencies for different times. The low frequency component is in the centre of the spatial Fourier plane and would get the greatest exposure than the high frequency component.
Leaf vs Focal plane shutter - Photography Stack Exchange
2016年11月30日 · With a leaf shutter, everything is exposed at the same time, so the subject will just be blurred in the direction of motion. Note that this blurring will happen with the focal plane shutter too, since the exposure time is the same.
Leaf Shutter Life Expectancy - Photography Stack Exchange
2021年5月25日 · If you compare an early in-lens aperture type leaf shutter to an early fabric (silk) focal plane shutter, then yes, the leaf shutter will likely last longer (in both age and actuations). But if you compare the leaf shutter commonly used in compact mirrorless digital cameras (e.g. my Fuji x20, x100, etc.) it will have a life expectancy more ...
medium format - Does leaf shutter work in HSS with Any strobe ...
2017年4月11日 · A leaf shutter, however, works by having overlapping leaves iris in and out, so the sensor is uncovered from the center outwards. HSS pulsing, in this case, would do nothing but illuminate the frame from the center outwards, causing a gradient (kind of like vignetting).
Why are there no full-frame lenses with leaf shutters?
2015年4月7日 · the shutter closes and cocks, while. the mirror swings out of the way. the dark curtain opens (the part of the dark curtain will be played by the focal plane shutter in a hybrid design) the leaf shutter opens for the required time, then closes. the dark curtain (FP shutter) is closed. the mirror returns, while. the shutter opens again for ...
Panasonic FZ1000: Flash FP high-speed sync oddities, 1/16000s ...
2020年4月7日 · Because the Panasonic LUMIX FZ1000 uses a leaf shutter, there is no maximum sync speed; the flash can be used throughout the entire range of mechanical shutter speeds, as high as 1/4000s (1/3200s unless stopped down at 32mm equiv. 135 or longer). Ordinarily, this means that FP high-speed sync isn't normally necessary.
Will a leaf shutter with a smaller diameter than the back of a lens ...
2024年11月16日 · If the open leaf shutter behind the lens is open and visible through the front of the lens as the smallest restriction when the lens' aperture diaphragm is wide open, then the shutter will reduce your lens' maximum f-number. You will also experience a corresponding change in depth of field.
Shutterless vs global shutter - Photography Stack Exchange
Mechanical Global = Leaf Shutter with iris design. This shutter type is less common, and people don't even think to refer to it at all. Even though the entire film/sensor area is exposed together, some may not consider this a true global shutter because light from different parts of the lens are exposed differentially, (see MichaelC's comment).
