Previously used several shutter release, from the beginning of the dozens of cable shutter release line to the nikon D810 bought the color wireless timer shutter line.
Thanks to the help of a local friend, the eggplant purple smart shutter, a Bluetooth shutter release. I remember that when I last looked at the shutter, there was only an infrared shutter that was plugged into the phone's headphone jack.
Next, out of the box, by the way to compare the difference between the two products, convenient value for friends to buy after the release line.

Do not send batteries, saying that there is a bad battery delivery. The packaging is great, the design is very good, and it's much better than my previous packaging. Skin-like shells don't like it and are easy to rub off. The weight is very light and there is basically no weight, the line is good and the quality is very good.
By contrasting with the wireless size, the weight is wireless this weight. The Bluetooth shutter has only one indicator in front and one behind the button and wireless has two buttons and a small status display.
experience feelings
Next on the machine, used similar products, installation does not need to look at other instructions, are used in front of the interface. The Bluetooth shutter is also placed on the hot shoe. There is no snapping thing and it is fixed by friction. I think this design is good, it should be the advantages brought by the weight of pro, it is very convenient to disassemble.
This is the installation of the wireless shutter, the line does not have to change, directly for the above receiver on the line.
I use the iphone 6p mobile phone to download the corresponding software.
First, turn on the Bluetooth shutter. Press and hold the light to turn it on. You can search it and the shutter name can be renamed.
A shared 9 function single shot, continuous shooting, B and so on. . . Let me talk about my feelings.
In the single shot mode, pressing and holding the focus to release the shot is very simple. Dragging the left alarm clock is a timer. 
In the continuous shooting mode, press to start continuous shooting, releasing the end, automatic mode is to set the shooting time.
The b door is similar to the above. The function of the remaining time-lapse photography of the B-door is not used and the curve is not used. I rarely use the delayed-time video to use it.
I think the most convenient is this voice control. It is very suitable for a group photo. After I click it, the sound reaches the blue ball and it is very convenient. I also found that if you keep the sound more than blue, you can shoot continuously, which is interesting.
Shake it, vibrate it and take a picture. Continuous shaking will not always be done.
If you do not understand, there is help to view
For a period of time, the main feelings are as follows:
The mobile app is indeed much stronger and more direct than the shutter release. Until now, I didn't understand the setting of the shutter release. This product is very convenient and intuitive.
I have a student party, take pictures of the scenery, and take some pictures of houses, take tripods and shutters, so I also try to bring eggplant to shoot. The function I need is a simple single shot. The problem I encountered during the shooting process was that Need to constantly change positions, move the feet and adjust the level, etc. The old flat color can be clipped to the hand, but with the eggplant, my remote control is a mobile phone, it can not be adjusted in the case of holding the mobile phone, and the mobile phone It's not like the shutter stick is in my pocket. So in the end it is not very useful, unfortunately, the final exam and the recent bad weather did not go upstairs shooting haha, it is estimated that it will be very convenient, set up hands and pants pocket ha ha ha very good. There is more electricity.
Advantages: full-featured, clear and easy to use.
Disadvantages: mobile phones are sometimes inconvenient to take, it seems more power, shutter time is not very convenient (may be the reason for the larger mobile phones, but now mobile phones are relatively large), no feel, blind operation is not convenient. The shutter is unstable and sometimes does not respond.
So you want to buy a Bluetooth shutter if you are a delay, video shooting users must be very suitable for you. If you just need the same simple functions as me, I think wireless may be more convenient, and it is much cheaper (this 200 or so, the basic wireless more than 100 will be able to get). Everybody has the choice to buy, write for the first time, welcome to comment.
