SO please excuse my poor memory - it's been a while since I shimmed my IQ180 / Alpa STC combo.
I'm upgrading to the 3100 and so it seems to me that there's no need to shim it (or even, really, to remove the shim I already have in place) because the reason it was needed for the 180 was that there was no real possibility of focussing in magnified live view therefore I was using a Disto and an HPF ring on my Rodie - and they relied on the camera/back relationship being exact.
With the 3100 I can focus on the back in live view so I assume that the shim is redundant - so much so that I can probably leave the old one in unless it is stopping me reaching infinity.
Is that right, or am I missing something? Also, is there any point in taking the HPF ring off the Rodie 40 HR (if that can be done) to reduce bulk?
and complexity.
I guess I'll be retiring that Disto now, though it does have a surprising number of alternative uses!
Thanks in advance....
