I think 55mm center is correct, i can’t remember why it was set to 58. I barely have enough tower to use the 300mm lens without the rotary lol.
I’m not too comfortable digging into the machine much more than just opening it right now as I have a pretty long trip coming up soon and i dont want it to be in pieces and not have time to put it back together before i leave. I appreciate all the advice you’ve given me. I have more than enough to go off of for now, it’s been extremely helpful! I’ll try to check the forum more often from now on.
