This is equipment for smoothly adjusting the focus of a lens during video shooting. I purchased it on Amazon and used it a few times. Please check the condition in the images. On Amazon, it was sold under the name "NEEWER A-B Stop Follow Focus C2, Applicable to 15mm Rods". Everything shown in the 8th image is included. The wrench is not included. * The shipping method may be changed from Rakuraku Mercari Bin to Yuuyu Mercari Bin. * Because it is also listed on other sites, it may be deleted suddenly. * Please read the profile before purchasing or commenting.
