Lens not reaching infinity focus?
Hi All
I purchased an m42 screw 200mm f2.8 and m42 to eos adapter to use in astrophotography.
AS can be seen from the attached photo I can't seem to reach focus.
I tried a 135mm m42 screw lens as well , same problem?
Using a 30D modded camera , tried it on a 40D unmodded , same problem?
Has anyone had this issue and solved it?
Is it the adapter thickness (one I have is the thinnest I could buy)
