I purchased Sony NEX 5N this fall and overall enjoyed the camera (see my review of
Sony NEX-5N 16.1 MP Compact Interchangeable Lens Touchscreen Camera With 18-55mm Lens (Silver) here http://www.amazon.com/review/R3FN42SUEPJ1PA/ref=cm_srch_res_rtr_alt_7). The one issue I had with the camera was ability to see the LCD screen in the sun, but I knew this OLED viewfinder was coming and hoped it would resolve the issue. I received it yesterday and I am very pleased!
I am attaching 8 photos to the customer photos which I will be referencing in this review (they can be viewed by following a link under the stock photo at the top of listing).
The OLED display is very clear. Not only does it help me to see the image perfectly, it also allows me to see text and numbers better as it has a control that allows you to adjust it to your eyesight. I am slightly far sighted and was able to get the display perfectly calibrated to my eyesight. The adjustment can go much higher and lower, so I know it will continue to work if my eyesight changes. Photo #1 contains a schematic which shows all the controls labeled in red.
The OLED display has to be attached/removed to the camera while the camera is turned off. Once you connect it, there is a lock screw that holds it down. One of my concerns was that I could easily knock the viewfinder out of the connector while using the camera, but with a screw down mechanism there is no danger of that. The eyepiece if firmly in place while I pressed on it with my eye. You can see the screw down mechanism clearly in photo labeled #6.
The eye piece can be adjust in many different positions so you can place it at different angles depending on how you need to hold the camera, so it works much better than the fixed position eye piece. I am attaching several photos showing the angles of the viewfinder to the camera. Photos 5,7 and 8 show the different positions of the viewfinder. I left the camera's lens cap in the photo for size reference.
The OLED display comes with an end cap which protects the connector and soft cloth bag, which protects it from scratches. Photos 3 and 4 show the viewfinder with the end cap on and off, as well as the bag.
The weight of the viewfinder is 1.1 oz.
The instructions recommend that the OLED viewfinder is always transported separately from the camera to avoid damage to the connectors.
There is a button which controls whether the LCD screen is on or off when the viewfinder is attached. The options are to have the display in both viewfinder and LCD screen or either of one of the two. I found having both on is handy when you want to use the screen to control the location of the focus. Auto focus prefers the center of the camera, and I often like off-center focused images for better composition. Even in the sun I can see the general area of where I want the focus to be, and then I look into the viewfinder for the final shot composition. Since the camera gives feedback to where the focus is located (the green square) I can confirm that my touch screen operation did what I wanted it to do. It is not a perfect solution for focus override but it works.
If you wear glasses it possible to remove the rubber eyepiece cup from the unit, but I did not find this to be an issue when I tried using the camera with my eyeglasses on. Photo #2 has a good view of the rubber eyepiece.
OLED viewfinder is very sensitive to water. More sensitive the camera without the viewfinder. If you don't have a rain jacket for the camera, it is best not to use the viewfinder in the rain.
The flash and the viewfinder share the same connector, so they cannot be used at the same time.
The viewfinder is not compatible with SONY NEX-3C. NEX-3C is a very similar camera to NEX-5N that came out a few weeks before NEX-5N, with the main differences being it and NEX-5N being slightly lower price, incomparability with OLED viewfinder, and no touchscreen.
I LIKE
1. Clear image which I can see in the sun
2. Has diopter adjustment for perfect eyesight calibration
3. Lock screw holds it firmly in place
4. Allows me to control when I want LCD on (for touch screen focus control) and off (for battery power savings)
5. Lightweight: 1.1 oz
I DON'T LIKE
1. The price
Overall, it makes the camera much better for my use and I recommend it.
