  • How to Check Lens Sharpness – “the simple way”
  • Lens Reviews often provide the most accurate and comparable idea of how sharp lenses are since they tend to provide standardised data on lens characteristics. Specific distortion percentages, measurements on the exact EV loss due to vignetting and sharpness ‘blur’ units make it easy to get an idea of how the lens is likely to perform and how it compares to other lenses.

  • Autofocus Points And How It All Works
  • Autofocus sensors work by measuring the difference in contrast across the sensor. A sharp point of focus will have a strong edge contrast, with the edge weakening as it becomes more blurry. This is the principle on which the autofocus processor determines that maximum sharpness has been reached.
