I just got my camera today and have had infinity focus issues as well. I'm using OCT-19 lomo lenses, with a cieco adapter. In the past I was able to fit my 18/35/75/100 on a Canon EF. At the moment only the 100mm spherical, and 50mm/75mm anamorphics focus properly.
My 18/35/75 have all been serviced in the past year, and when set to infinity they are in focus on objects about 3 ft away. Perhaps it's my adapter...but very frustrating that I have a camera, accessories, and lenses....but can't shoot with it!
