I have one from Wayne and although it is convenient and works well when set up correctly, it only focuses by distance to the object or by magnification. It can be tricky to get decent shots imho.
If you are purchasing for your own use and research, then they are wonderful. If you are thinking about using for sales or customer images, i think that there are better options.
I concur. Personally I think even for personal use and research much more flexible and better equipment can be had for same or lesser cost than any of these type gadgets. They are good for showing customers things like repairs that maybe needed or the like. Decent for field work. But the really cheap $50 ones work for this as well.
I just feel they're far too limited for real beneficial use.
Gemstones and jewelry photography is better done with a Panasonic LX3 or LX5 + Raynor add-on macro lenses, all of which can be had for same or less money and offer a lot more features, flexibility, and better image quality as well. With cropping they can even do decent shots of inclusions too with the MSN-202 or 505 Raynox lenses.
A digiscoping adapter + P&S camera with your existing microscope works for micrographs as well much better.

Wow! That might even be within my price range . How many U.S dollars is 45 Euros?
I can't help you with your other questions but I think this is the same item sold in the U.S. for a penny under 50 bucks with free shipping (if you're not in a big rush): http://www.adorama.com/VORDAS.html
I'm thinking about buying one of these as well. Cascaillou, is it possible for you to post an image of the adaptor and camera attached to your microscope? Thanks in advance.
well to take a pic of my camera would require another camera (if I can find one I'll post a few pics).
However, the link I provided shows the adapter and camera fitted on some kind of telescope, it fits my microscope occular exactly in the same way (the only difference is that the occulars of my microscope are a bit more vertical angled than the one of the telescope shown in these pics, but that still works just fine)
to barbara: universal adaptors should fit most scopes, just check the occular diameter range the adaptor can fit (the one I have fits any occulars from 28mm to 45mm diameter, and the occular tube needs to be at least 3cm long)
The main issue with such setting is that all you get on your camera screen is a tiny circular image (2cm diameter) in the middle of a black screen (note that the camera zoom was of no help here). That means that you cannot see what the camera will be picturing just from looking at the camera screen. This is a problem to centre and focus your pictures, unless your camera can take pictures while being connected to a large screen displaying what it sees. So I did set the diopter ring of the scope left occular to show roughly the same as the right occular, then setted the adaptor+cam on the right occular, which still allow me to look through the left one to get an idea of what the camera will be picturing.
about camera settings: no zooming, flash off, macro mode on, timer on with a delay of 2seconds. I always take many pics, as I know that many will be blurry or uncentered. Not so easy. I guess with some practice I will get used to it.
here's what a pic looks like (before I modify it using windows pic editing tools):
ps: note that I used to take similar pics just by holding my camera right against the microscope occular, but using a digiscope adaptor makes things more stable and more comfortable.

Thanks, guys! I do believe these are both the same item. Okay, so it will fit on my microscope, now I wonder whether it would work with my camera . The ad says for point-and-shoot cameras ... mine is a Canon PowerShot A640. When it is first powered on the lens telescopes out from the body (it is a 4x zoom lens). Anyone know about these and if it would work with the adapter??

barbara, what I use is the same kind of camera (with telescoping objective) and the adapter fits it fine (the adapter is made so you can move the camera back and forth over a few centimeters so the camera objective can be stuck right against the microscope occular)
As I said, the main issue with this setting is to see what the camera sees. I suggest that before buying an adapter, you try the following: place a stone under the scope and focus on some inclusions within the stone, then stick your cam objective right against your microscope occular (holding the cam with your hands), you'll notive that you can't really see anything on your camera screen (the displayed image being to small for you eyes to see any details of what the camera actually sees). Then take a pic (try to move as little as possible, keeping the cam stuck to the occular), and then link the cam to your computer to see the pic you've been taking: you'll get something similar to the last pic I posted, meaning a black field with a tiny circular image of the stone at the center (which will need to be enlarged for better understanding, which can be done using windows pic viewing tools). Of course, enlarging a pic means you're loosing resolution.
Things will be exactly the same when using the adapter, but instead of holding the camera with your hands, the adapter does it for you.
I wonder if there are any lenses that could be added to the digital camera so to solve this problem, allowing the cam to take a "full pic" instead of picturing the inner surface of the occular cylinder as a black field with a tiny circular image in the center. Is that what you call a "macro lense" swishman ? (my camera does feature a threaded ring around the objective allowing to attach some kind of adaptor for special filters, maybe I could attach a macro lense here)
