Following the arrival of my FD-m43 adaptor yesterday, the FD extension tubes I won also turned up this morning!
I was keen to try them out to see what kind of magnification was possible. Suffice to say, stacking all 3 tubes gets you in quite close, and it quickly becomes apparent how much use image stabilisation is. Yes, this is where those of you with Olympus bodies can feel quite smug
, however, it is still perfectly possible to get the shot, and I'm really looking forward to trying this in the field!
For what it's worth, here are examples of the kind of magnification possible with the various tubes fitted. I hope these are useful...
GH1, Massa FD->m43 adaptor, Canon FD50mm only @ f2.8
...with 12mm tube
...with 12mm & 20mm tubes (+32mm)
...with 12mm, 20mm & 36mm tubes (+68mm)
I'm really not sure what the actual achieved magnification numbers are I'm afraid, although I guess with all 3 tubes, it's beyond 1:1 - perhaps someone can clarify the maths please...?
