This adapter works well. I hadn’t used an M42 lens before. Just a tip for others, when the lens was mounted on the adapter, it was upside down. After some confusion, I noticed on my lens there were 3 set screws that, when loosened, I was able to rotate the lens right side up. Just to be clear, the adjustment screws are on the lens, not the adapter. I hope this tip helps others with any confusion like I had.
