[QUOTE="Ahmadkawi, post: 135086, member: 7194"] Well, I have a ton pictures taken with my camera, that are somehow all non-dental I'm afraid. I do have pictures from work though. Taken with the clinics camera. The setup we have there is a Sony Alpha 35 D-SLR, a 50mm macro and the Sony Macro twin flash. I never paid attention to the 1:1 reproduction ratio though. And when I did, I found that do that with the 50mm lens is quite difficult. I'll see if I find any photos that would be helpful. I tend to live by the rule of if you want honey go to a bee. So I want to buy a camera I'd go to a company that makes them. Nikon and Canon are the popular names that come in mind. And if you look online you'll camera kits made specifically for dental photography. But there are many companies, other than those too. That being said, I should say that the Sony camera we have is actually very good, and I hear that her bigger more expensive sisters are very good indeed. I did a lot of research before I bought my camera, but I missed certain things that I have now learned, which is really the point of writing this. It's a cautionary forum post. So now you know what to look for in a camera. I suppose, that if I had waited a while, I would've bought a Nikon D600 or more optimistically a D800. Boy ,oh boy! By the time I went to bed, I realized that I forgot to talk about two things; RAW files and Focus Motors. [B]Focus Motors[/B] Lenses autofocus using an autofocus motor which is either built in the camera or the lens itself. For instance my D3200 doesn't have a motor, and for me to use autofocus – which I actually don't – I have to buy a lens that has the focus motor built in to it. In the Nikon world, those would be AF-S lenses. Bigger Nikon cameras like the D700, D600, D800 and upwards have a focus motor, so they can use AF lenses. There are lenses that are strictly manual though, and they would need manual focusing on any body. I'm not sure of the terminology when it comes to other brands, so you'd have to the homework I'm afraid. [B]RAW Files[/B] Suppose you have a D-SLR and you go into the settings for file format and you choose JPEG. What happens is that the camera doesn't shoot in JPEG. It shoots in RAW then does some processing to convert it into JPEG, which means a smaller file size with loss of detail. Check the link below for more information. But bottom line is, you should shoot in RAW, and so you should make sure that the camera you're using offers RAW. As it turns out RAW files are not strictly universal.
