I just picked one of these up pretty cheap, but I can't locate the instructions. Anyone have a digital copy?

If not can anyone tell what the "switch" in the front of the lens does? I presume it is activated by the installation of the accessory lens, but I'm not sure what it does.

I don't have the accessory lens, but was planning to use a good 2x achromat.

Advice welcome! Snarky comments will be ignored!

I’ve used one in surgery at a previous job.
Been too long to remember much about it. Switched to a 105 macro and a ringlight.

Thanks. It appears that the addition of the accessory lens changes the setting in the lens, which is what I had guessed.

I hope you found the instruction manual useful.

That is a very fine lens. I use it extensively for medical/surgical photography and ballistics research work many decades ago- it's also is great for photographing things like printed circuit boards, watch and clock movements and any othere applications where a ring ligh would be applicable. It is amazingly sharp considering it is an older version and it makes for a nice macro lens even when the ring light is not employed.

I wonder if you have the full kid with the power supply and the addition add on accessories.

Good luck with it, enjoy the lens and the best of the season to you!

I have the lens, AC power supply and cords, so it is completely functional. I am missing the auxiliary lens and a battery power pack. The lens I'm to worried about, but the battery pack would be nice to have for field work. Apparently the lens actuates a coupling in the front of the lens to "tell the lens" that it is in place. I'm curious how it will function with a good quality 2x diopter.

Thanks again for the instructions. They will be very helpful.
