kenko ST-90 I last used this about 20 years ago. I used it when shooting with a video camera. I didn't use it very much, and when I tried setting it up, it seems to be usable as shown in the photos. However, it is very old, and there may be defects that I can't see, so I'm selling it as a junk item with scratches and dirt. Recommended for video materials, shooting props, or parts. Please consider purchasing only if you agree with the condition shown in the photos. Returns will not be accepted after the item arrives, so thank you for your understanding. Thank you for looking! ^_^
