Yes — but it depends more on the lens than the camera body.

On modern interchangeable-lens systems, aperture rings are much less common than they used to be. Many current DSLR lenses, such as Nikon G-type lenses, do not have an aperture ring at all, so aperture is controlled from the camera body.

If you want on-lens aperture control, the usual options are:

• use lenses that still include an aperture ring
• use older/manual lenses, often via adapters

Most cameras can use manual-aperture lenses if the mount and adapter allow it, but you’ll usually give up some electronic features such as autofocus and automatic aperture control. In many cases you’ll be working in manual focus, and sometimes manual exposure as well.

There are also a few digital cameras with built-in lenses that include an aperture ring, but this is not common in mainstream DSLR or Micro Four Thirds systems.

So the feature hasn’t disappeared entirely, but on-lens aperture control is now mainly found on certain lenses, older lenses, adapted manual lenses, or a small number of niche/fixed-lens cameras.
