Pentax K-3 II Electronic First Curtain Shutter (EFC Shutter) Behavior

An electronic first curtain shutter (EFC shutter) allows zero vibration exposures*. While an EFC shutter offers little or no benefit over the mechanical shutter for shorter focal lengths, it becomes critical for telephoto lenses, where the shutter itself will blur the image. For example, the Leica M240 mechanical shutter causes severe blur.

Both Nikon and Canon have EFC shutter options as options for Live View shooting, once enabled (Nikon also requires the use of MuP mode and 1/2000 sec or slower).

* In theory there could be a vibration issue when the shutter starts to close if the camera requires closing the shutter to finalize the exposure, but in practice I’ve not seen any issues even with the 50-megapixel Canon 5DS R.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • Make better images by learning how to get the best results right away.
  • Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
  • Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
  • Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
  • Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
