New image of the OWL drop in filter adapter.

This is an image of the new Micro Four Thirds OWL drop in filter adapter devleoped by MXcamera.

The advantages you get with that drop in filter are:
1. for ultra wide angle or fish eye lens, no way to install the filter. Rear drop filter is the only way to solve the problem.
2. For Cine lens, like Canon CP / Zeiss CT lens, the filter is thread is 95mm, very expensive filter, a rear drop in filter can reduce the cost
3. easy to change drop in filter and will not affect the setting, front lens filter may change your setting when un-installing, especially the lens is not internal focus….
4. The setting of rear drop in filter will not change while you change the lens, more efficient
5. For telephone lens, the lens body is too long, when you attached the lens on tripod, this is difficult change the filter.
using rear drop in filter, you can change the filter and keep an eye in the viewfinder.
6. MX is now developing the tele-converter lens for this adapter, so you can upgrade this adapter to tele-converter easily.

The filter will go on sale early 2014. And they will sell it on their eBay Store.
