The biggest news in the camera industry this month is that Nikon is reportedly halting development of new SLR cameras, marking the end of a 63-year run..

Many serious shooters still prefer an optical viewfinder, too. They want a subject view they can trust and believe that a physical view via a prism and mirror is superior to an artificial electronic display. The drawback, of course, is that you can’t see the image when you shoot it because the mirror lifts up to block the display.

The last big thing is battery life and handling: Flagship DSLRs have heavy bodies and big grips that make for stable shooting platforms, particularly with the massive telephoto lenses used by sports and wildlife photographers. They’re also covered with dials and buttons for easier handling. And the optical viewfinder obviously doesn’t drain the battery, so DSLRs can shoot many more photos on a charge.
