Canon EF 50mm f1.8 STM - Custom cine lens Rehousing

thingiverse

This customized lens housing is optimized for Canon EF 50mm f1.8 STM. "The new EF 50mm f1.8 STM keeps the same focal length and aperture of its predecessor, not to mention a six element / five group construction. But instead of five diaphragm blades, there’s now seven, promising smoother out-of-focus effects, and a closer focusing distance of 35cm compared to 45cm. The plastic lens mount of its predecessor has been replaced with a metal one, it’s fractionally heavier by 30 grams and employs a slightly narrower filter thread of 49mm. Most importantly the slow and noisy micro motor AF has been swapped for Canon’s more modern STM system for quicker and quieter focusing that’s ideal for movies." Unfortunately, I said it was a cinematic lens re-housing, but there is little that improves the functionality of the AF lens itself. Focusing manually will help a little. It is just a cosmetic change. Enjoy!
