Fujifilm WCL-X100 II

Quality optics and adds a greater field of view to an already excellent camera. Also.... It's tiny!

Perhaps a bit expensive but it's made extremely well, superb build.

There is very little loss of image quality with the converter fitted

The additional width of angle is pretty disappointing. When I first got it I had to keep checking that there was actually a difference by taking the same shot with and without the converter. With hardly any shot I have wanted to take at a wider angle...

Quality build, ease of use.

It's Fuji so not cheap!

Light weight easy to use
