4. Mirrorless Interchangeable-lens Cameras
Combining some of the benefits of both compact cameras and DSLRs such as better image quality from larger sensors, lens changeability, compactness and lower price (when compared with DSLRs), these cameras are becoming popular in travel photography.
Yet, these cameras do have some drawbacks such as:
  • No phase detection auto focus,
  • No optical view finder (only electronic view finder),
  • Limited number of lenses available, and
  • No compatibility with SLR lenses.
Popular models are:
      Sony NEX-3N, NEX-5R, NEX-6 and NEX-7
      Canon EOS M
      Olympus PEN E-PM1, E-PL3, E-P3
      Panasonic Lumix DMC-GF3, DMC-G3, DMC-GX1
      Samsung NX200
      Nikon 1 V1

Note:
  • Some updates were made on this page in 2013.
  • Camera manufacturers are notorious in naming their model numbers, especially for DSLR models. A DSLR's capabilities cannot be simply guessed by just looking at its model number. Always look for the full specification.
