Wi-fi.

Part IV is here.

There are excellent descriptions of how to enable Wi-fi in the GX7 at CameraLabs.

I’ll add some personal experiences below.

Wi-fi:

Wi-fi on the GX7 means that you can send images to your portable device of choice – cell phone or tablet, iOS or Android – after first having downloaded the Panasonic Image App from the AppStore (iOS) or GameStore (Android). The app is free. Further, once the GX7 is connected to the device, you can control just about anything on the camera – focus (using the touch screen on the cell phone or tablet), framing rate, movie mode, you name it. However, you cannot send or receive emails while the camera and device are connected as they share a wi-fi circuit unique to the two devices. So if you download images from the camera to your device, you must then switch to your regular wi-fi or cellular connection before these can be sent out.

Here’s the order of events to get wi-fi working:

• Turn on the GX7
• Hold the wi-fi button on the rear until the blue diode lights up
• Go to Settings->wi-fi on your device, find and activate the GX7 wi-fi connection – it’s named ‘GX7-204E2A’. The first time you do this you will have to input the password shown on the LCD display of the GX7. Thereafter you can simply save this password to your device.
• Open the Panasonic Image App on your device – your device will take 10-20 seconds to connect to the GX7. Sometimes this fails so turn the GX7 off and on and the app on the device off and on. Re-pair the wi-fi and try again after doing this. It usually works by the second attempt, worst case.
• The Panasonic Image App will now display on your tablet or cell phone exactly what the lens on the GX7 is seeing. Magic! You can now control the GX7 fron your device.
• Take a picture by touching the camera icon on your device. Enlarge any image to full screen by touching it.
• You can now download the picture to your device by touching Playback on the device app, whereupon all the images on the GX7 will be displayed on the device in thumbnail format. Touch any thumbnail for a full screen view.
• The Panasonic Image App does NOT recognize Panasonic RAW images. You will see a preview with a symbol but you cannot email the image. Thus you must set the GX7 either to JPG or RAW + JPG. In both cases, the JPG file will be both visible on the device and can be emailed out once you revert to your normal wi-fi or cellular connection.

this is a RAW image which cannot be emailed.

I have successfully tried the above with two iOS devices (iPhone5 and iPad Air) and one Android one (Nexus7 tablet).

While steup is a bit clunky, operation is simple and effective. It’s a nice feature to have if you want to email images on the run or control the GX7 remotely.
