* You have to remove lens from camera and modify always shutter opened.
* You need rear lens holding ring to adapt lens with this adapter.
* Lens flange back is pretty strict. 3D print machine that Shapeways has been updating often return different results. I usually make lens adapter a bit over-inf. If you couldn't get infinity focus, you maybe get infinity focus by cutting or scraping it.
