Could anyone recommend a lens of about 50 mm focal length
optimised for 1:1 reproduction ratio ?

This would be used with a c-mount video camera with an image
sensor size of 8.8 x 6.6 mm so a wide angle coverage is not
important.  What is important is the ability to resolve at
least 10 microns (preferably much better than that).

I have already considered enlarger lenses, but I really want
something for 1:1 which is outside their optimal range.

It should have an iris, and ideally a focus mount, but this
is not critical.  Any fitting could be used.

Thanks in advance,
