The 70mm lens in the 110 lineup is kinda legendary. A couple of years I passed on a complete Pentax 110 kit still in the box at a rock bottom price. Drat...
Yes, they work well and cover well on my X-E1 & X-E2 with a Chinese adapter from eBay.
The 50/2.8 is great (my favorite), the 18/2.8 will vignette in the corners (but a 5x7 frame hides a lot this problem), the 24/2.8 is super sharp in the middle ... but falls off a lot towards the corners.
I have recently acquired the 70/2.8, but I have not had the time to put it through its paces. All seems AOK from the first quick tests.
I have also just installed a home-made diaphragm in my second copy of the 18mm to get some more sharpness and DoF hopefully. Need to test it as well.
Below is an image with the 24/2.8.
