MicroMV DCR-IP1E - Ultrawide lens adapter
Wasn't a fan of how the default focal length felt so I modeled this adapter which press fits onto the front face allowing me to mount a wide angle adapter I use for a different camera.
The exact product page for the lens doesn't exist anymore but if you can find one with either a 33mm filter thread, or 30.5mm thread then I have 2 models that would work.
Personally I prefer the Ultrawide mode (without the macro lens) which is much wider than even the wide mode, but adds lens distortion.
It fits quite snug onto the front but it's not secure without being held in place, which I've been doing with my hand as you see in the image, but I've also occasionally secured it with a rubber band which was good enough for me.
