This optimization kit includes a custom achromat lens and a 77mm thread ring specifically designed for the Sony PMW-EX1/EX3 XDCAM . This corrects the issues in the Sony lens and gives you sharp focus across the entire image. This kit is as add-on for the Letus35 Extreme. This is a direct replacement for the stock achromat and includes an optimized thread ring specific to the EX1/EX3 as well. If you are purchasing an Extreme new, you can add this kit to your order from the Letus Extreme product page. Optimization kits ordered with an Extreme come pre-installed.

NOTE: If you received your Letus Extreme before December 2007, please contact us for information on this kit specific to your adapter.
