I thought there was a standard RMS to Nikon mount adapter, but I have not found one on the Web yet so will keep looking.

I'm not that handy with a lathe; but I've bought an adjustable adapter that extends the tube length of a standard RMS (Approximately 20mm Thread Mount). This extension adapter has male threads that mount to the microscope nosepiece and female threads that mount the objective lens.

I should be able to attach an objective and secure the end thread inside a Nikon back lens cap with a suitable nut - that might do for now.

I did see a Nikon F Mount adapter ring on eBay a few weeks ago that had a thread on the inside for attaching some type of micro lens. Should have bought it. Can't have enough gizmos and widgets.

They are out there Dave. Thanks for the lead.

Also did a Google search for RMS to Nikon mount adapter and came up with 2 interesting links; but this is all new territory to me. Will have to look more carefully when I have more time.

For adapters in the UK try:-

For the US Beljan Manufacturing are said to provide the same service:-

I also noticed in Lester Lefkowitz "Manual of Close Up Photography" a geared slide called "Velmax". I put it into my search engine and came up with these links:

They may be able to replace milling machine tables in your set-up's:-

Hope those are of interest?

There is some interesting info in those links DaveW.

Ideally, for the D100, it looks like I need a Nikon BR16 and BR17; but it seems it will be quite an adventure trying to find them. One fits inside the other enabling an objective to be attached.

Do a search on EBAY for them and if it comes up zero click on the bit that says EBAY will e-mail you when one comes up for sale or auction. I did this with a close-up lens and got an e-mail back next day saying one had just been posted. As I had recently searched I would have probably not searched again for a while and missed it. You can also put a WANTS ad for free on EBAY.

For those who might be interested. I found a universal adapter that should fit nicely onto an SLR or bellows attachment.

I bought one and at the time of writing this there were another 2 available.

Type the eBay item number in the the eBay search and you should find it.

eBay item number: 130038068725

Hope this is of help.

Good find!

I'd question whether it's really a "universal" adapter, though. Looks to me that you have to tell them when you order, which camera you need it to fit.

In regard to some of the questions asked earlier in this thread, I have included a link to a PDF document. It's only a short article; a blend of science and art written by Thomas Eisner.

Thought you might appreciate it.

About two years ago I purchased (eBay) from Beljan Mfg. (see DaveW link above) an adapter that has female RMS thread to male T-mount. Very well made, and with the T-mount, very versatile.

Also, the extender tubes on this site could also be used to make an adapter.

This topic seems to have become a place to collect links to interesting hardware. That's OK -- let me add a couple for posterity.

Really Right Stuff has a nice screw-drive macro focusing slide, 1.25mm/turn. It's their model number B150-B. See http://www.reallyrightstuff.com/specialty/index.html# . If it's not immediately visible, you'll probably have to browse for it under Speciality Products. Typing the model number into their search box does not find what you want.

For precision benchtop stuff, one might consider the Cross-Roller Translation Stages from Edmund Optics, http://www.edmundoptics.com/onlinecatal ... 1&search=1. They're expensive, but the specs are impressive.

The most precise linear positioners that I've run into are the Edmund Optics Micro Positioning Stages, http://www.edmundoptics.com/onlinecatal ... uctid=1844. These are screw-driven at 80 turns per inch. But they're small -- would only be suitable for positioning the specimen, not a camera. They also come in a motorized version, http://www.edmundoptics.com/onlinecatal ... 5&search=1.

However, one concern I have with all these positioners is that it seems difficult or impossible to get much more than an inch or two support area around the attachment point. This is not much leverage to counter the shutter vibration of an SLR, even with mirror lockup. The milling tables have more like 5 inches and are designed for heavy loads, so I suspect they're a bit more forgiving. They're also quite a bit cheaper. For bench use, I'd still go with the milling tables.

For field use, the slickest setup I have seen is the one by Charlie Krebs, illustrated at http://krebsmicro.com/forumpix/0099sm.jpg and described in http://www.photomacrography1.net/forum/ ... php?t=5461.
