Smokedaddy, no, it doesn't. Ray, that's a fascinating lens, looks more modern than the Ultra-Micro-Nikkors. If I still had money left I'd buy it, but I'm broke for at least the next half year. I am surprised there is no label for the wavelength. The newer UMNs usually had the mercury line name engra...

Here is a really good one; unlike the Zeiss lenses which are fairly old technology, this is from 2008 and uses UV light: http://www.ebay.com/itm/141-TAMARACK-SCIENTIFIC-5X-248NM-LENS-530-0801-/111126379871 I have one of these. Don't know if it will work or not, since there seems to be a gas port, as...

These are hard to search for, since the owners don't always label them correctly. But there are several for sale now, not only on eBay but also in semiconductor surplus stores. Here is another: http://www.ebay.com/itm/Carl-Zeiss-Lens-S-planar-1-1-6-f-50mm-4360A-Nr-6205792-/282643030884?hash=item41ce...

Edit- Robert posted some good info while I was writing...I also recommend Marco's document. I might be interested in buying one of those cameras, smokedaddy, if you are ever interested in selling one. The most well-known of these lenses are the Ultra-Micro-Nikkor lenses, sometimes available on eBay ...

If one can accept the limitations of monochrome photography and short working distance, they may be pretty exciting. They do present some stacking...

Banania, yes, that is the Olympus lens that works best for focus stacking in the field. It works very well if yo can hold still. In the field so far I have only done stacks up to m=1. It can do stacking when reversed with an adapter I made, but in this case the working distance is too small for anyt...
