Samyang MF 14mm f/2.8 MK2

The MK2 update of Samyang's popular 14mm f/2.8 manual focus lens adds weather sealing and a focus lock function, which is particularly useful for long-exposure astrophotography. It features a de-clickable aperture ring and a redesigned 9-blade diaphragm. The optical design continues to offer a very wide field of view with corrected distortion, making it a staple for landscape photographers looking for a robust, purely mechanical wide-angle option. Check that the focus lock ring engages correctly and prevents the focus scale from moving. The aperture ring should switch smoothly between clicked and de-clicked modes. SDS verifies that the weather sealing at the mount is in good condition and checks the lens for any signs of decentering, which can be a common variance in ultra-wide lenses. Ensure the fixed lens hood is not damaged, as it provides essential protection for the protruding front element.
