Curious if this objective would be of much use -

40X Nikon Achromatic Finite Conjugate Objective

I wouldn't expect much for that price, but if it is useless, then I'd like to know. I understand that it will require a bellows and adapter, which I have.

Not useful for macro work:

Working Distance (mm): 0.6
and likely it will need cover glass (not disclosed! Shocked although typical for this kind of objective)

Thanks, Pau. I did check and it doesn't require a cover slide, but you are right about the working distance (though I assumed all super high mag had very limited WD...)
