WOW ! .... OK ....S o......talk me through what and how you did that .... well  roughly as I have no idea how you have done that and achieved such an astonishing result ...   but I'm probably a bit stupid I've decided ..... BTW thanks for the comparison size wise ...  brilliant result too ... I am in awe ....

Just wonderful Weary......it is great to know that there is another user of vintage and redundant lenses from the old days of film.

Detail here is amazing.....

Have you spotted the video I posted in the Latte Lounge for you yet ?

Clicker + Bill,  the lens is 16mm diameter fitted tightly into a c-mount adapter then mounted onto a helicoid and a 28mm extension tube all sitting on my Wemacro focusing rail,

the fly is positioned on a piece of bark which is blu tac 'ed to my xyzr fine tuning placement platform. The fly is lit by three flash guns, the Janson led lights are there to illuminate the subject for focusing.

The final picture was a stacked image of 174 images @ 55 microns crunched down with helicon focus software.

The picture above lacked a lot of contrast initially so I made a deep lens hood flocked on the inside and I flocked inside the extension tubes this has improved the image quality.

The resolution of this lens is claimed to be 3600dpi in reality its around 3250dpi my other scanner lens is over 4000dpi and is noticably sharper,

tests of these lenses have shown that they're all apochromatic so no red blue fringing!

 If I’d known it was that simple ... ....blah blah ... :whistle:

:lol:

Seriously  Andy.... hats off to you .... thanks for the explanation and the pic of the rig...... it will give  many of us an insight to the technical expertise required as well as the patience necessary to produce your stunning images..
