28-80mm Macro

Following the extension ring debate I got a second hand macro lens. It seems to work fine although I want a dedicated macro eventually.

When I go to the A position on the aperture ring. What is actually happening???

As you already know, a 28-80 Macro zoom is not a true macro lens, but it may well focus quite close.

The aperture ring can be set to any of the marked apertures, and usually this will mean that the camera will set the shutter speed (aperture priority or Av) or you could use manual settings of the speeds.

The "A" setting is used when you want the camera body to control the aperture. So, for example, you could set the shutter speed and let the camera set the aperture (shutter priority or Tv).

Some bodies require the lens to be set on "A" to be able to function correctly.
