    Macro generally is when a lens will reproduce an object the same size on film/sensor as it is in life.

    Hey that’s pretty cool. Is it really what happens?

      Yep, most macro lenses such as the 90 to 105 range from Sigma, Canon, Nikon and their ilk tend to have a designation like 1:1 in the description.

      This is normally based on a 35mm frame size, for cropped sensors the magnification is greater.

        Actually for cropped sensors it’ll still be 1:1 but “cropped”

        You can get more magnification if you use extension tubes or specialized lenses.

          Cropped by way of a smaller sensor, but magnified if you compare a “full frame sensor” camera and a “crop sensor” camera with identical pixel counts. A penny will have a penny-sized projection on the sensor, but the image from the crop sensor will have ~40% more pixels of the penny.

      Depends, I think. In the same order of magnitude definitely.

      Edit: this makes me wonder, is it possible to get an orthographic perspective with an ordinary size (but maybe not standard) lens on a normal camera?
