  Akkor idézem a dpreview-ról:

  Just to recap, the shutter systems on most mirrorless cameras have tended to work in a different way to SLRs. The shutter is held open during normal live view, and when the shutter button is pressed it closes so the sensor can be reset, then quickly opens again to make the exposure. This process has been blamed for sometimes introducing slight image blurring across a specific range of shutter speeds (usually around 1/60-1/250sec).

  With an electronic first curtain, the exposure is started by a purely electronic process (as the name implies). Some manufacturers such as Canon and Sony have used this for several years, as it can be used to entirely eliminate any vibration from the physical shutter action. Olympus's implementation is however subtly different - the physical shutter still closes and opens as usual, but the exposure is slightly delayed to allow any vibrations to die down, and then started electronically. This is also the first time we've seen it added via a firmware update, and specifically to reduce image blurring.

  Lehet gondolkodni.
