komentarz EPL2 vs NEX

"With the launch of the Sony NEX3/5 in the middle of 2010 Olympus found itself competing with not just other Micro Four Thirds models but an entirely new breed of mirrorless interchangeable lens camera.

With a larger, higher resolution sensor, higher resolution articulated screen and extremely compact proportions, the NEX models look like a very attractive alternative not just to the E-PL2, but to Micro Four Thirds system cameras in general. This is particularly true of the NEX-3 which is priced appreciably lower than either the E-PL2 or Lumix GF2. The NEX models offer exceptionally good low light performance as well as fast continuous shooting that's exploited in modes that automatically composite multiple images to produce excellent results.

So what's not to like about the NEX models? They don't have the range of lenses available to the Micro Four Thirds system, but that will likely change in time and meanwhile there are third party adapters that will let you attach other lenses. Like the Lumix GF2, the NEX models rely on lens-based image stabilisation. They also lack a built in flash or hotshoe, though a small flash unit is included in the box which attaches to the accessory port.

Then there's the question of handling. Though firmware updates have added, among other things, revised menus, button customisation options, better manual focussing control, and aperture control in movie mode, the NEX menu system and software remains better suited to point-and-shoot operation than advanced manual control."

Sony da lepszy obrazek ale z manualną optyką przez adapter. Bo na razie z systemowymi obiektywami kiepsko...
