Professional DSLRs: Modern Marvels of Imaging Technology

Professional DSLRs: Modern Marvels of Imaging Technology

Cameras with reflex mirrors and optical viewfinders are still the pros’ top choices.


Professional photographers generally stick with what works. That’s why most of them still opt for traditional digital SLRs with reflex mirrors and optical viewfinders. Professional DSLRs are holding their own despite inroads from high-end, mirrorless interchangeable-lens cameras with electronic viewfinders (EVFs).

Peruse the impressive specs of the digital SLRs we’ve detailed here and we guarantee you’ll come up with your own list of cogent reasons why. However, it all boils down to a few basic facts. All these cameras deliver a full complement of advanced, often unique features along with awesome real-world performance.

Of course, all of them accept the complete range of legacy lenses in the average pro shooter’s arsenal. In addition, their robust, ergonomically contoured, well-balanced, weather-resistant bodies look and feel like “real cameras” with conveniently placed traditional controls.

Indeed, today’s top DSLRs represent the logical evolution of the genre and are classic examples of successful adaptation. The happy result is a superb group of cameras built for the rigors and artistry of professional photography.

A Selection of Top-Notch Professional DSLRs
