Nice job what adapter do you have? Why did you stop the lens down?
I am using the Fotodiox M43 - NEX adapter. It has a LOT of play... Therefore I shimmied it best as I could to try and achieve infinity focus, I am LITERALLY on the razor's edge with it... At F2, I can't really focus perfectly, comes close, but not perfect... Thus I stopped it over twice to F2.8 and I am pleased with the result.
I shimmied it using Aluminum paper, to get the lens closer to the sensor. I also adjusted the infinity focus on the lens, but even then, it is only so far. I bought a bathinov mask printed specifically for it and do my best to twist it as far as possible.
In hindsight, shouldve just bought the Sony E mount version, but again, this one was a good deal and the results arent the worst. F2.8 is STILL beastly fast :-)
I will try to put it together with my ASI 183MM and filter wheel and see if I can reach infinity with that... I got the adapter for that as well. Now just need to figure out how to use it with a rigel n step, how to mount the motor and use a belt etc... Then ill be in business... IF I can get infinity focus with the dedicated. I reprocessed some of the images, they are down in the link. Rossette especially looks a lot more defined.
