Overview

The Auto Tele-Seimar 135 mm f/2.8 is a third-party lens, likely made by Tokina. Optically, it delivers good sharpness and detail, especially for portraiture, with pleasing blurred foregrounds. However, contrast is poor, requiring significant post-processing boost, and backgrounds can appear flat and lifeless. Build quality is solid with a built-in lens hood, but focusing can be tricky in bright light as the focus patch may black out. It suits portrait photographers but is less ideal for general use.
