As you cannot still change your Diana Mini lenses like you can with Diana F+ here is an idea for getting that different effects on your photos!
It’s so simple and effective! Have yourself these different adapters for the Lomo LC-A+ – Tunnel Vision and the Fisheye adaptor. Just stick the metal rings from these adapters in front of the lens of your tiny but cute Diana Mini. Then just mount the lens you want to use and shoot like crazy! Definitely a must try!
I only tried this only with the square format setting of the camera though, but hey it’s your turn to experiment! ;)
