I'm a new Chronos user that will be doing some outdoor shoots this spring and summer. Some at night (things like fireworks and hopefully some lightning strikes). I'm using mainly Canon lenses with a EF-mount to C mount converter.
I've done a few trial runs at night, and I'm running into some difficulties with focusing. Low-light scenes don't show up with enough clarity to focus using the Chronos LCD screen. With my DSLR, I can get a nighttime infinity focus lock using things like distant streetlights and car lights, these are things that understandably won't show up at all on the Chronos LCD. I have an external monitor on order, but I'm assuming it won't show much either. I've tried getting a focus lock using my DSLR, then moving the lens over to the Chronos without any success. I've also tried doing a daylight focus at infinity, then marking the focus ring on the lens for later. The problem is that some of my lenses' focus rings are electronic without hard stops, meaning that marking the ring at a certain position doesn't guarantee that the internal focusing mechanism will actually be in the same position later.
Would it be possible to adjust the Chronos backfocus to exactly match my DSLR? That way I can focus a lens using the DSLR, then transfer it to the Chronos. Right now that's my best idea, but wondering if anyone else had any other methods that have worked for you.
