Enabling and Testing for Electronic First Curtain Shutter (EFC Shutter)

Many digital cameras offer an electronic first-curtain shutter (EFC Shutter); see Shutter Vibration / Shutter Shake vs Electronic First Curtain / EFC Shutter.

Enabling EFC shutter

Check the camera manual; support for EFC shutter varies widely: sometimes it is not available, sometimes it is available but with restrictions (shutter speed, shooting mode), and every vendor seems to choose a different name for the feature.

Typically the EFC shutter requires the use of Live View shooting mode, though cameras that “do the right thing” might offer it in other modes, such as without Live View but with the self-timer, or in high-res pixel shift mode.

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.

Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.

  • Eases into photographic challenges with an introductory section.
  • Covers aspects of digital sensor technology that relate to getting the best image quality.
  • Technique section discusses every aspect of making a sharp image handheld or on a tripod.
  • Depth of field and how to bypass depth of field limitations via focus stacking.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • How to test a lens for a “bad sample”.
