Late last week, Samyang announced a 100mm f/2.8 macro lens and a cine-style variation with a T/3.1 aperture, geared focus and iris, and longer throw distances. Macro lenses, of course, have the ability to focus at much closer distances than their non-macro counterparts, which makes them perfect for capturing extreme close-ups of smaller items that would otherwise be difficult to photograph in extreme detail. That makes macro lenses great for a number of purposes, including nature and product photography, but for filmmakers, macro lenses are great for capturing highly-detailed inserts and cutaways.
Here's some footage shot with the new lens to give you an idea of what it can do. Just as a heads up, you may want to mute the video because the song choice is -- questionable.
Here are the basic specs and another photo of the new 100mm T/3.1:
