If you spend time on the camera forums, the “experts” there will complain about the “crop factor” applying to depth-of-field as well as field of view. The cruz of the complaint is to infer that you cannot get an out-of-focus background with such cameras because f/5.6 is really more like f/11.

Not everyone can afford a big, fast, lens. It’s particularly hard to find the loose change to buy a big telephoto lens. While the lesson I offer here applies to ALL cameras and ALL lenses, regardless of manufacturer OR format, it is most apparently impactful when you are shooting with telephoto lenses.
