Comparing VR “Active” and VR “Normal”

Whereas the Handheld/VR Shootout page compares using VR in Active mode to VR Off, this page explores whether there is a difference between using VR Active versus VR Normal mode. This setting might apply only to telephoto lenses; wider angle lenses typically have no such choice.

On Nikon VR lenses, the VR mode is chosen using a slider switch on the lens itself.  Canon uses a similar system on its “IS” lenses.

No single test can determine for all possible scenarios whether VR Active should be preferred to VR Normal, or vice versa. The performance of one mode over another may vary depending on the camera used, the technique of the photographer, motion of the photographer (e.g., in a boat or vehicle), whether a tripod is used, etc.

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”.
