I Need help understanding Macro Lens for digital photography pictures of teeth, what to buy.? - dental digital camera
In our practice, we begin to look for a digital camera to take pictures of the teeth very closely. The problem is that we are all fans of photography and digital cameras. I said, we need a macro lens for this. Some have said we need more zoom capability, I do not think that is correct.
I suggested that a digital SLR camera from Nikon need, as a rebel, who, of course, in a flash. Do you need a ring flash?
Nikon knows that the rebels $ 800 and more, and the macro lens would be a separate cost, is not it?
Some expect more in the office that could do this with a device much cheaper, he said: "In your dreams!
Please advise ...

Dental Digital Camera I Need Help Understanding Macro Lens For Digital Photography Pictures Of Teeth, What To Buy.?

For a very clear and detailed pictures of teeth you need a lens that the ability has focused on short hops. It would be a front or a macro lens. The addition of a ring of light would even illumination from all sides, shadows and reduce as much detail as possible.
Also, because you will work in close cooperation, it is essential that you have an SLR, when the viewer actually sees through the lens to use.
I want a Cannon EOS Rebel XSi with EF-S 60mm f/2.8 Macro USM and recommend Macro Ring Lite MR-14EX.
Move photoace - it is a real expert here. I would just add that it is not the goal - the 105 macro and flash-proposed compromise would be perfect. However, you do not need super-strength or characteristics of the breath of the D300, you can also provide satisfactory results with the D80 and save $ 1K.
Oh, and you're right: The zoom is not a substitute for the macro. The fact that a lens can zoom in and things appear closer, does not mean that the lens will focus quite close - it functions as a macro lens.

In relation to go macro lenses, you could be much worse than a Sigma 105mm macro, which would be 1:1 Macro or size target.
Your question: "Is it necessary Ringflash Yes, yes. The number of Ringflash Guide is the most suitable for macro photography. If you use a regular camera flash, it would be to adjust the light output to about 1 / 4 to the flash output 1:8 to avoid a "Whiteout", while Ringflash care, which is already done.
Sigma makes this selection of accessories including Canon, and you will see that it is very suitable for this kind of shots you want.
What ring flash, one of the best on the market is also made by Sigma (no, I do not work for Sigma), and get the power you need flash macro photography without spending a small fortune.
Whatever the device used, the lens quality really counts. Even if you are a low-end Canon digital SLR cameras, the quality of the optics is what makes the ultimate difference. Your patiI thank the parents make an informed career choice, especially if a good color match the desired result, in the case of veneers or crowns, etc.
Several years ago, developed a special Polaroid camera for the dental profession. In the yellow pages of the UK, comes after the demolition of dentists.

Shot a few dentists in my area. I use a Nikon D200 and a 105mm VR macro macro with a "flash disk (as in CSI from time to time to see). The package is Nikon R1C1
Too many buy something like this is about $ 1800 for the D300 costs (replacement for the D200), $ 760 for the lens and flash $ 680 for the macro. Not much with other tools in practice compared to dentists. Less than $ 3,500 if a good tripod and prosecutors.
Your dentist should be some experience with such things in dental school.
Ok, I will comment on the various components and can decide what to do.
With respect to the camera, you're right, you need an SLR camera, so you can see in the viewfinder exactly what is shown the picture. Now, the Canon Rebel did not work for you, it has a meter of land, which is for macro work is crucial. If you choose the top model Select Canon or Nikon. Each model of Nikon is going to work. If you are on the cheap that you go the D40x a great entry DSLR that takes exceptional pictures can only use to. If you want more control and options, which I think is not necessary in this case, take the D80. I personally use a Nikon D200 and I love him, but then no picture teeth, I insects and fungi, which I can both a challenge and it is certainly much harder than the teeth. So I need the additional features of the D200. If I am the teeth are not happy with the D40x.
You should not buy a SLR kit with the proposed target. You can buyany goal they want and in general can help you a little discount on the lens when you save the camera you buy money.
So what? Of course you need a macro lens, preferably a 1:1, that in fact size. Nikon has two versions of this, a 60mm and 105mm. There are others that have a "macro-offer" skills, but they are not real macros and gives only a ratio of 1:2 (half size). A macro lens is also on a horizontal plane and not from the common curve, which is based in the macro work is crucial. Many macro lenses are called because they help you closer to your subject, but that does not make them true, and macros that you have large images that you require.
In macro photography, the goal specified distance of the motif of the size of the object and the focal length of the lens. If you shoot a filling in the tooth, with the prospect of a short, 60 mm, it means you've really close (Porbably) a few centimeters, can be a problem with the patient. Greater focal length is really necessary for their implementation. Provided with the 105mm, but instead, at least a foot away from the objective of the subject that is easier to manage for you and your patients. In addition, the 105-mm lens, an image stabilizer with any camera movement is excellent. So in this case, I recommend the 105mm lens. I have both, and both are excellent lenses, but the 105mm is the best of what we are trying to do, since the constraints under which they work.
Finally, with regard to the lighting, I have a ring flash agree is ideal. You try not to create art, you try to capture the clinical details, so that it is important that you have a uniform illumination that all the shadows are eliminated.
Sigma has a good ring flash, it works perfectly with the Nikon. It is a reasonable price and with the 105mm macro lens provides a comfortable working distance, the patients of their sentence.
Nikon macro flash system, which refers to a game before, but I uhrsonally think it is not practical for what we are trying to do. It is also heavy, bulky and require more noise to trigger the recording.
Hence my suggestion of a Nikon D40 with a 105mm macro lens from Nikon and Sigma ring flash. That would be the cheapest solution for their needs. If you think you need a sophisticated, I would chose instead to the D80 with the same lens and flash. Another approach would be to kill.
Hope this helps a little.
