Summary: I buy for your price and yours features. Is good quality for your price. I dislike your many features but it has the necesary for a standard. If you has the camera for job, have you need more accesories.
Summary: I read about how the Nex-3N is much better than the Nex-F3, but I used both and that's not true. Both have about the same build quality. While the 16-50mm kit lens is smaller on the 3N, it yields very poor results in terms of resolution and colors. The 18-55mm kit lens on the F3 gives better detail. There is no point of having a big APS-C sensor with such a poor lens that washes out the pictures.
Summary: THE GOOD: The NEX 3N is said to be the world's smallest camera based on the APS-C sensor, which is the second-largest sensor (about 16mm by 24mm) commonly found in mass-market cameras. The result is fine photo quality in a small package, with good high-ISO performance. Moreover, the 16-50mm e-mount kit lens is optically decent, and retracts to semi-pancake dimensions when the camera is off.
Summary: Having used Sony Nex versions 3/5/7 this is a fine upgrade in regards to the power zoom, this make the camera so much easier to use and the new compact size is an advantage. However on the Nex 3 & 5 with the LCD screen only it represents a real weakness - in medium to bright light the screen image just fades out, useless. The Sony menu is not the sharpest system and its is for me a struggle to use quickly.
Summary: I bought the NEX 3 to take with me to New Zealand. I thought the compact size and the large sensor would make it ideal for quality photos. Previous models had the over-large 18-55 lens. I didn’t do my homework properly as I thought it would take one of those electronic viewfinders as an accessory - wrong!!
Summary: You might think "why worry about video on a still camera" but if you think that then you haven't been using some of the new Sony still cameras for video recently. Having a dedicated video camera makes very little sense unless you do nothing but video. I own the Sony HX9, RX100, A77 and A99 and all video at 50/60 progressive scan so I was quite shocked to find the Sony 3N has gone back in time to 50/60i.
