you must be a wizard at swapping lens tubes by nowRobertOToole wrote:I must have tested something like 100+ tube lenses mostly in the 80-120 range. I tested something like 20 or more 135-150s in the last month alone.
I've adopted your thorlabs SM2 setup and like it a lot, but but whenever I have to change extension it takes me ages to get everything back in order (flocking, alignment etc) - I don't want to imagine adding an extra tube lens in there.
I'm actually considering trying the thorlabs SM2 Quick Release Adapter (SM2QAF and SM2QAM) for the three lenses I have to swap a lot, keeping the base fixed with SM2 rings and swapping only lenses and needed extra extension. not cheap though.
I first was trying bellows but I find it hard to secure them as tight as the SM2 setup on a vertical system.
In any case, hats off to your lens swapping skills!
