Lens Trade? DJI15mm for Olympus 12mm?

Anyone interested in trading an Olympus 12mm lens (X5 compatible) for the DJI 15mm lens?

I will throw in 2 new B&W filters - never used - polarizer and 106 ND 1,8 - 6 BL 64 MRC.

I like the DJI lens, but would like to be able to have a bit wider perspective.

Thanks,
