Hi Everyone,
Am new in this, am studying gemology and acquired a trinocular microscope. I have on it a brass tube adapter with inner diameter of 23mm. I live in Shanghai, China, got the microscope straight from factory but they cannot give me any kind of advice on the camera I can use.
Does anybody could give me advice on what camera could fit/work for this application? Can i use a normal camera and need an adapter with a marco lens or do I need a specific camera?

Tim is going to help you see if you caan set up your present camera. If that does not work out and If you have to buy somethting new - and since you are in Shanghai - you could chat with 'Colin' at Chlight Corporation in Chengdu. See http://www.optics-china.com/content.asp ... tentID=334. They say that this device will mate to the trinocular port as well as it will to a 23mm eyepiece tube. I can't attest to the performance of these but have been sufficiently impressed in chatting with Colin to order one as a gamble. They are a little more than two hundred bucks - and no swingeing delivery charges for you, since you are only 'down the road' from them

Hi Tim, Kerensky, Lukeness,
Much thanks for the reply guys,...
Here is my microscope:
Camera: got a Canon G10, if could fit on this and just need an adapted from Canon, would be great.. if not I will consider buying a new camera (what would work?)
@Kerensky: thanks for the Colin link... Will give a call to these guys...
Looking forward to hearing from you~!

Hi Nick and welcome to the forum.

there are 2 ways to do it: 1) have a look to this topic: viewtopic.php?f=17&t=3679 OR 2) you can add pictures as attachment following the instructions at the bottom of the posting page.
Out of curiosity, how much did you paid for the scope? ciao alberto

Hi Roberto,
Thanks for the greetings and the pic tips... Scope price: hehe... good I believe... can't really tell you this,... I deal with factories and trade product from China for a living. But let say something around 1500 USD. How does such a scope retail for in Europe?

Hey Kerensky,
I checked with Colin... they offered me this, see enclosed file.
But got a question with this thing. MY scope has 10X eye piece and central magnification up to 4x So I got normally a up to 40 x magnification visusally. If I use the camera on the third ocular, I get the only 4x right? or do I need to fit such a camera with an additional 10 x lense to get to 40x?

Hi Nick,
it appears that there is a way to marry your G10 to your scope but I'm not sure you wanna go there... The G10's lens is surrounded by a dress ring which can be removed. This exposes a bajonet fitting to which a LA-DC58K adapter can be attached. This LA-DC58K adapter features a 58mm female thread at the other end.
Here comes the tricky part: you need an adapter with a male M58 thread on one end and a ~25mm (check the outside diameter of your trinoc) hole at the other with a lock screw so that it can be clamped onto the trinoc. Since you still have your camera's lens in there you will have no worries regarding parfocality (I think... do check it first: put a bit of tekst under the scope and open the lightpath to the photoport, hold your cam a few cm (mimicking the second adapter's length) over the port and look through the viewfinder. If you like what you see this method will work for you, see if you can use your cam's zoom to get rid of the black ring surrounding the image). A handy machinist should be able to fix you up with an adapter like that for not a lot of money.

It is a bit tricky to determine exactly what magnification a particular camera will produce, but roughly speaking the camera's lens is behaving like the eyepiece, and so you shouldn't need an additional lens.

Hi Nick
Just back on line after ---- well never mind...
Digital eyepiece etc. You've already received the essential advices you need. So, it's really up you you to decide what - to start with anyway - you are going to want your 'camera' to do. I took the view that it's likely to take me 6 - 12 months of using a gem-scope to really decide for myself on that and there what I need is some 'get-you-started' rig for still photography, with which I can experiment, push its limits with and find out what better solution to *my* needs I may want. For the moment at least, I can't see that I have any need for video. The device you were offered seems to be essentially a video capture device that is capable of single-frame capture. My preference was for something designed primarily as still capture device.
I note that the max resolution of the 'digital eyepiece' offered you is determined by it's 1.3 megapixel design. This may be OK for video but i'd prefer to have better for still photography. The device you've details of from me (and I am taking a gamble on) has 2 megapixel native resolution and this can be interpolated up to a 5 megapixel equivalent, using the software that comes with the device. Frankly, I'd be happier with 5 megapixel native but the price is good and 'needs must when the devil drives' I quite expect to buy another camera in due course.
Anyway, if you get the one and I have the other, we can compare notes on what we can get out of them

OR you could go for Tim's WILD M400 which is all ready prepped to take a dSLR camera and have all the microscope you'll ever need and just about the ultimate macro/micro photography setup. HERE
