I will have some adapters coming soon express if anyone is interested.

Best,

Robert

Also V38 to V38 would be a good one also, for lens stacking coupling. For Makro Iris lenses 37mm to 37mm reversing ring should work as well and that is coming soon. The hood sets the element back a few mm on some lenses so really the best way would be V38 to V38 or even better mounting in the Sm2 t...

Thanks David! 5 lenses at 3 magnification levels really was a l-o-n-g process. It took a lot more time and energy then I expected. The final results were rewarding since they all really did a spectacular job, especially with CAs and LoCAs! Once I spent hours and hours slogging away through a pile of...

Excellent work Robert! Can you remind me of the cost of the Mejiro lens? The Mejiro float lens has been updated a bit since this version. I've tried to get information out of Mejiro a few times with email but they won't give me any details since I am not in the Photonics trade. Also they have been ...

I did not ask for this the first time sin...
