This is an interchangeable focus screen for the Leitz Leica R4. Although it's listed for the R4, I believe it can be used up to the R7. I purchased this used for my R6, but I didn't end up using it. 【Included Items and Condition】 This item includes the focus screen and a cleaning brush. Overall, it shows little sign of use and functions without issue. Please check the photos. The included instruction manual details how to handle and replace the focus screen. There are also some notes written in red ballpoint pen. - Brand: Leitz - Model Name: Leica R4 - Manual: Instructions included - Accessories: Focus screen and cleaning brush - Condition: Used, minor wear visible Please refrain from purchasing if you are overly concerned about the condition, as this is a used item. Thank you.
