Letus has released a new 35mm Lens Adapter product with a greatly improved design. The latest “Letus Extreme” product revision includes a solid metal casing, swappable lens mounts, prism flip, internal batteries, and only 1/2 stop of light loss. Quite a roster of upgrades, and the light loss improvement is impressive…but does it hold up to the hype?

Ryan Walters has written an extensive review on the new Letus unit, and he was pretty impressed. He thoroughly tested the Letus Extreme, and has shared resolution and color charts, as well as vignetting and bokeh examples. Excellent writeup. Ryan pulls no punches in outlining the adapter’s pros and cons.

UPDATE: The Letus team has also shared Video Samples and a model Comparison Chart.
