=I am a doctor by profession and I was looking for a good macro lens for use with my Nikon D200 lens. There are a lot of times when we want to take a close-up macro photograph of a particular condition, or during surgery, so that we can archive it or fr sharing with colleagues for their opinions.
I tried many brands of lenses, including Nikon, Sigma, and Tamron, but they all had one problem or the other, and were terrible at the way they rendered colours. Some of them were reasonably sharp, ut form my purposes, I found that none of them were sharp enough.
So I asked around and was referred to ProPix There I was shown for the first time, the Carl Zeiss Makro-Planar T* 100mm f2 lens for the first time. I tried it at their showroom and then came back home and looked up the reviews and feedback about this lens.
I was really surprised to see that every one who ever bought this lens was very happy with it. So I went back to ProPix and bought myself a 100mm Carl Zeiss Makro Planar f2 lens. Today, I am happy to say that I am very very happy with the lens, and its image quality. The lens has a metal body which is very rugged. The focusing is extremly smooth and feels solid. It is so easy to focus this lens, and it is the brightest lens I have ever seen on my camera. At and aperture of f2, this is also the fastest macro lens in the world!
