Nikon entered the mirrorless interchangeable-lens marketplace last year with the Nikon 1 J1 and Nikon 1 V1 models, very compact cameras built around the same 10-megapixel CMOS sensor in a new CX format.

Olympus’ first mirrorless interchangeable-lens cameras were inspired by the company’s popular PEN 35mm compact cameras of the 1960s.

Fujifilm made a real splash in 2011 with the X100, a little gem with a great design, a unique hybrid viewfinder, a big APS-C image sensor and a built-in wide-angle lens.

The replacement for Panasonic’s GF3 entry-level "pocket" Micro Four Thirds model, the new GF5 improves on its predecessor in a number of ways, including a higher-resolution LCD, higher ISO capability, more effects filters, an improved grip and additional video capabilities with a built-in stereo microphone.

Canon’s long-anticipated mirrorless interchangeable-lens camera finally materialized in Summer 2012.

There’s no question that mirrorless, interchangeable-lens cameras are increasingly popular—more mirrorless models were introduced last year than traditional DSLRs.

For many years, the two most popular types of digital cameras have been compact models and digital SLRs. Each offers advantages over the other.

Digital technology not only has changed the way we take pictures, but it’s changing the way cameras are designed. The vast majority of photographers use either compact digital cameras or digital SLRs.
