I think it is the lens - but still I'm using cheap adapters, so it wont be a disaster if the adapter end up being unusable or only usable for the Jupiter Lens.
Just for comparison here is an example of F4/infinity at 100% crop with my Volna-9 50mm:
I would have expected more IQ from the Jupiter, so I'll try to see how much more material is to be removed with the adapter still usable
In the first grinding cited above about 0,6mm was removed. |
