The light-sensitive Samyang 135mm f/2.0 ED UMC lens is suitable for MFT, APS-C, and full-frame sensors, and impresses with its brightness of 1:2.0. This manually focused prime lens offers vibrant colors and a beautifully smooth bokeh, thanks to its 9 blades that create a nearly round aperture. These are just a few reasons that qualify the Samyang 135 f/2.0 as an ideal portrait lens. The light reserves are sufficient to achieve good results even in poorer lighting conditions. As a "short telephoto," it is also appealing to journalists and wildlife photographers. The internally focusing lens consists of 11 elements in 7 groups. The glasses are multi-coated, providing outstanding imaging performance and sharp contrasts, along with the ED lens. The lens feels great in hand and does not noticeably alter the balance when focusing due to its design.
