>>12459566>without exposureExposure is the time the sensor/film is exposed.
You can dial it up or down however you like, but no exposure = no image.
Usualy DSLRs can do between 1/4000 and 30 seconds (longer in bulb-mode).
With an electronic shutter you can go faster, but introduce a lot of rolling shutter.
And then there is the issue with lenses that can have quite different speeds:
>f/5.6typical zoom-lens on the long side
>f/4.0typical zoom lens on the short side
>f/2.8many primes, a few rather expensive zoom lenses
>f/2.0Mostly primes and realy few zoom lenses
>F/1.4A few prime lenses, usualy normal lenses or short telephoto
>f/1.0Rare as fuck and insanely expensive.
>f/0.7Zeiss made 10 of these for NASA, two ended up in Stanley Kubrics hand to film in candle light with 200 ISO filmstock.
Each step above is 2x as much light, meaning the Zeiss Planar f/0.7 is 32 times as bright as your typical kit-lens at the same focal length.
