SDM only, no RDM adapter. It's old, but the variable size is large, offering a wide coverage range, which is convenient. I think it's the size range I use the most. The friction on the boom end variable lever in the third photo is too light, but it functions without any problems. I was using it until recently. It's not suitable for intermediate to advanced users who are particular about their equipment, but it's good for beginner practice. Local pickup only in the Jonan area of Tokyo, Zaimokuza, and Miura.
