Summary: A lot of people have negative reviews, but I disagree with them. Lens is made of mostly metal which is pretty amazing for the price. Lena size is big hence using of tripod is necessary to avoid out of focus pictures. This lens is my fav.
Summary: Happy with it. Lens works manually just as it should. Later I ordered the 2x doubler for it, so save your effort and buy both at once. Make sure you order the correct adaptor for your camera. Sony cameras might need A mount or E mount.
