SIGMA 35mm 1:2 DG DN φ58 Lens Hood LH636-01. Only mounted, never taken outdoors. Since it's 35mm, I rarely used the hood, so it's been stored in a dehumidified storage. It's expensive to buy new, so if you're looking for a good condition used one, please consider it. - Model: LH656-01 - Size: 35mm - Brand: SIGMA - Function: Lens Hood
