Review on 📷 Rokinon 100mm F2.8 ED UMC Telephoto Macro Lens for Sony E-Mount Cameras - Full Frame, Interchangeable Lens by Brittney Merrill

I bought this lens to photograph groups of small chemical vials. The ampoules were approximately 2.5 cm high and had labels in fine print. The lens was used on a Sony A7Rii and did an excellent job of detail resolution. I did the same job a year earlier with a Sigma 70mm f2.8 macro lens on a Nikon D810 and the Rokinon/Sony combo was noticeably better. The extra range of 100mm macro compared to 70mm or 55mm is noticeable as there can be more space between subjects and the front of the lens. This simplifies the lighting and makes the composition more flexible. I would buy this lens again at any time. It's also damn good for portraits. Keep in mind that this is a manual lens with no electronic connection to the camera. You have to focus it by turning the ring and assessing the sharpness on the screen. You must rely on your camera's A or P setting for automatic exposure, or calculate exposure manually. An easy task for me after years of macro photography with medium format cameras and bellows attachments. Maybe not so easy for children who grew up with automatic digital cameras. bottom line? The lens is optically and mechanically very, very good.
