Your AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED lens has a maximum reproduction ratio of 1:1 at the the lens' minimum focus distance of 0.314 meters (1 foot). Your Nikon D5300 is an APS-C camera with a sensor size of 23.5x15.6 millimeters and a resolution of 6000x4000 pixels. Let's look at the capabilities of what you are using. It has a specific magnification, a fixed focal distance, it can be easier to clean, it's compact and probably has a built-in light, and live view, so you can use it to see in real time. So you need to see what is in reality what you need. It is less than 2x (1.8)īut if you see the image for example on a FullHD 23" monitor, at full size you can see the sugar grain of 1mm at about 11cm. The optical magnification is not that great. I posted this image of some sugar grains. In this other question: What kind of lens to photograph a 1 mm object? So in optics terms, 25x means A LOT! of magnification, and I mean a LOT.īut as you are a dentist you probably do not really mean that. Take a look at this question: What does "magnification" mean? In the photographer's world magnification is relative to the optics. It can also mean that you need to understand about motion blur if you are using a slow speed, so probably you need to increase the sensitivity of your camera, increasing the ISO. If you are not focusing well either you need to practice or you need to take a look at your lens, for example, if it is autofocus.īut it can also mean that you need to practice your "macro photography skills" like holding your breath, holding the camera firmly, etc. If that is the case you probably need a ring flash. Then "Blurriness" could mean that either you are not focusing well or that you have motion blur. Assuming you know how to use it, and you have tested it, for example outside of the mouth of a patient, you know how close you need to be and what "magnification". You are actually now using a 105 mm macro lens. I am going to separate them and you can choose an option. I expect that the high cost of some of those microscopes can be a problem, but it looks like there are also models that aren't so expensive. They often have their own light source, and they sometimes include a camera as well. There are microscope models made specifically for dentistry that can give you the magnification you want from a distance of 200-300 mm. Beyond the obvious physical and hygienic problems with sticking a lens into a patient's mouth, getting close enough to get the view you want inside a small space will make it impossible to get enough light on the subject.įor dentistry, you need something that'll give you good magnification from far enough away to be hygienic, and also far enough to give you room to work. Macro lenses get a lot of their ability to magnify just from being able to focus at very short distances - it's like looking closely at something by holding it close to your eye. No DSLR lens will provide the level of magnification you need, particularly at a focal distance that makes sense for dentistry. Below you will find what comparisons that are available for you to choose from.What shall i do please to have high magnification inside pulp canals with high magnification more than 25xīuy a suitable microscope.
