Photographers wanting a slim compact system camera now have a few models to chose from.
The Sony NEX-5 (and NEX-3) and Samsung NX100 have a distinct advantage over the Olympus Pen E-PL2 as they both have larger, APS-C-sized sensors with 14.6-million-pixel resolutions.
Of the two cameras, the NEX-5 is smaller and lighter, but for enthusiasts the shortage of buttons may make it slow to operate.
The NX100 is probably more of a direct competitor to the E-PL2, although it lacks the built-in flash that many will see as an essential requirement for a camera of this type.
There is also micro four thirds competition in the form of the Panasonic Lumix DMC-GF2.
This camera uses the same resolution sensor as the E-PL2, but is more advanced.
