Utterly newbie question -- Canon EF-S 60 aperture adjust

Here is a question that will reveal my utter ignorance of my new Canon EF-S 60 macro lens with a EOS 20D body. How do I adjust depth-of-field with this combination, since there is no aperture ring? Thanks much!

In manual or Av mode you would adjust the aperature with the dial near the shutter release button on the camera.

Stephen, you can use aperture settings in camera to adjust DOF. The smaller the f no, the bigger the aperture and you get a narrow DOF. Using a larger aperture gets more of the subject and environs into focus. From what I've read an aperture of f/11 should be good to get almost everything into focus. I hope that made sense...

So, if I understand, there is no manual aperture ring, it's done via the body. Kinda like a fly-by-wire system for a camera. I guess that's why this lens only works for a few digital cameras -- maybe it's the trend for lenses: software control.

its been around for a long time. eos = electronic operating system and canon has many film cameras under this name. the lenses that attach to them have been around for a while, its nothing new

All (or almost all) EOS mount lenses work this way (about 20 years now). The lenses just do not have a mechanism to control the aperture. Something 20 years old is hardly new, all of the EOS fim cameras work this way also, so it is not a "digital" thing.

This control just happens to be in the camera body.

This is really not any sort of deal, controlling the aperture on the lens, or in the camera body is really not that different. Turn a ring on the lens, or rotate a ring on the camera body.

Having it on the camera body does make it very easy to control. You control it with the same finger you would use to fire the shutter release.

Enjoy! Lon
