  • Should I use the sharpest aperture on my lens?
  • In an ideal world, you would always be able to use the sharpest aperture on your lens. In practice, though, you will find yourself stopping down to smaller, diffraction-prone aperture values if you need more depth of field. A large portion of this article is simply the background research and calculations that went into the finalized charts.
  • How many lines can a perfect lens resolve?
  • A perfect lens can only resolve 50 lines per millimeter (lpmm) at f/64. Therefore, don't stop your lens down to f/45 or smaller unless it's necessary. So how many lines can a perfect lens resolve at other apertures?
  • This question is not directly answered in the passage, but the given information can be used as a reference to understand the concept.
  • What is the minimum f-stop value a lens can maintain?
  • The range of f/3.5 to f/4.5 provides the minimum f-stop values (widest aperture diameters), that this specific lens can maintain while shooting at the minimum and maximum focal lengths, respectively. For example, the minimum f-stop value this lens can maintain is f/3.5 while shooting at 18mm.
  • Do you need a longer lens for a portrait?
  • In the case of a portrait, that’s actually desired. You do not want your person to blend in with the scenery, you want them to jump out. Using a longer lens will help you do that. Here are some examples of how longer lenses compress and isolate.
