Mikołaj My Olympus has a wi-fi function that lets you connect to a phone, control the camera remotely and download the photos. The app only gives you access to JPG files, but when you're connected, you can open a web browser and enter a URL like 192.168.0.10/DCIM/100OLYMP/PB0... to get the raw file.
Mikołaj Another option is to use a micro SD card with an adapter in the camera. Then you can take it away and insert to the phone.
Kazzi my phone doesn't have microSD port, I used SD OTG card reader, but at that time there was no .orf support at Snapseed and no Lightroom Mobile. Great idea about the browser! I'll try it soon
