Hi everyone,
We are testing a setup with the Letus Extreme and an EX1.
Unfortunatley we can't get the Ground Glass in proper overall Focus. The right and the left edge are out of Focus while the center is in Focus. We allready adjusted the Lens to the right Infinity Focus had a look at the Ground Glass and all that was allright. Still no Focus throughout the whole frame.
We also do have the EX1 Kit (77mm thread ring & the special EX1 achromat lens).
Can anyone help us? Thanks.
