Is there a reason more for a NEX 5 or even 6 issue? Although the display has less points than the resolution of the bigger brothers. But compared photos I could not adjust worse and could also assess any problems. All the rest I look then at the ehehin large PC monitor. And in bright sunlight does not use the best display. Here an electronic viewfinder would be naturally good. But the costs properly charge and increases the camera. The display can be folded only upwards and not downwards, for example, when holding the camera overhead. One must decide how often you make extreme overhead shots themselves. Aside, the display can not fold the way. This can not also the expensive NEX 6 and 7. For this you can display the complete fold up and draufschauen example, when shooting or self-portrait from the beginning and check what you just because filming. That goes with the NEX 5, but not with an NEX 6 or 7 .. Also the focus was limited to the contrast focus. I once compared it with a NEX 5, which has the new software contrast and phase autofocus. So currently I can here find little difference.
A good combination is the new, very compact and lightweight kit lens SEL 16-50mm. You can order beautiful film also. The movie mode is 5R / 6 slightly slimmed to NEX and makes max. Movies with 50i or 30p movies = Vollbilder.Das but usually more than adequate. The high frame rates of 50p and more you need more if you want to use later slow motion. The films are very good, low noise and have well balanced colors. There is still an HDMI output in order to control the film while recording on a corresponding additional monitor, for example, Phottix, can. Problem of NEX cameras 3-6 is the lack Abspeichermöglichkeit settings. Man photographing and filming normally with other settings that you need to be always new when switching between photo and movie.
If you want to avoid something fiddly battery charging in the camera, a charger from a third party eg Bundle Star Battery Charger 4 in 1 incl. Charger for Sony NP-FW50 + 2x Patona replacement battery for Sony NP-FW50 can treat yourself with replacement batteries, matching Sony NEX -6 NEX-F3 NEX-7 NEX-NEX-7B 7C NEX-7K NEX-3 NEX-3N NEX-C3 NEX-5 NEX-5N NEX-5K NEX-5R SLT A55 A33 A35 A37 etc - with Car Adapter , ....
Overall, you get a very usable camera with the NEX 3. It is priced even lower than the precious compacts and even has a large sensor and interchangeable lenses.
