1. The lens body of this lens is made of aluminum alloy, and the surface is sprayed with a matte plastic protective layer. (This plastic protective layer is also the only flaw of this lens. After long-term use, it will peel off. For a user, this should not be a problem)
2. The imaging conforms to the requirements of a macro lens Indicators: good deformation control, accurate color restoration, and sharp imaging. 2 SLD lenses control dispersion to ensure high-definition image quality, floating focus system, and perfect internal focusing (focusing action also keeps the length of the lens unchanged). The ultrasonic motor HSM mode provides ultra-quiet high-speed focusing and full-time manual focusing.
3. It is very suitable for the content you need to shoot, especially insects, because the working distance is farther than the 100mm macro lens and it is not easy to disturb the insects. And this working distance does not affect the lighting arrangement. This lens also comes with a tripod mount design (something other brands only equip with 180mm macro lenses).
4. If you are not interested in shooting insects, you can choose a 90mm or 50mm macro lens. However, if you want to take photos of insects into consideration, this 150mm macro lens is the best choice.
