Leica is updating the way that we transfer photos to our mobile devices. The new app is called the FOTOS app which will replace the Wlan app that has been available. Functionality is very similar to the previous version. You still connect by WiFi but now the password for your camera is saved in the app. Also Android users will be able to transfer photos. The program also works with more cameras, not a dedicated program for each camera as before. Now you can transfer from a S, SL, M, Q, Tl, CL, D-LUX, and V-LUX from one app and all photos are kept in one place in your Leica FOTOS app. Then you can work on the images in the Lightroom Mobile or your other app of choice. I love the way that the app connects with the camera via a QR code that is scanned in the FOTOS app. Very slick. You can set what quality the files are downloaded as, jpg or dng as well as jpg quality, white balance and metering setting. When in the file viewer you can select single or multiple images. The camera can be controlled remotely with the app and the ISO, shutter speed, and EV can be set from the app.
