FishEye is a little application that I wrote over the weekend, which fetches your pictures from your WiFi-enabled Sony camera through the “Send to smartphone func.” feature.
Thanks to @vlagged, @MeeGo-Junky and @mr.yo for the inspiration:
If the Xperia 10 IV indeed launches without camera support, I am prepared!

Feel free to file issues and feature requests on Gitlab, and let me know if you use it.
If you find camera APIs for other brands: feel free to add support, make issues, and discuss. Ultimately, I’d like this to become an all-brand camera control app.
