Review on Samyang 12MM VDSLR CANON F1312101101 by Christine Goldwater

All the prerequisites, pleasant feel, super-clear glass This little one also focuses around 7.5 inches. 3 inches from the focal plane. In case you don't know, T stands for TRUE Light Transmission, this is actually a 1.5 light transmission lens. F is a mathematical expression used to calculate depth of field. F- does NOT correspond to real light transmission! Tripod photo taken with Olympus E-M5 (closest focus), T16, ISO 200.5 sec.
