- Brand: Leica Thank you for viewing. This is a Leica lens hood 12583. It's a hood for the Summicron 50mm. I purchased it a long time ago and didn't use it much. I'm selling it because it's just been sitting unused for the past few years. When attaching it to my Summicron 3rd, the spring for the lock is a little sluggish in one place, but it still works. The accessories are as shown in the images. No returns or exchanges to prevent swapping. Thank you.
