B+W 52mm to 58mm Step-Up Ring (Lens to Filter) #5B New

The 52-58mm adapter can be easily screwed onto the front of any 52mm lens, and allows you to convert the 58mm threads of accessory items (such as filters, hoods, flashes and lens converts).

Tip: If photo equipment is to include lenses with different filter thread diameters, the B+W adapter rings can adapt filters and supplementary lenses to different lens diameters. This is less expensive than buying several lenses with the same filter type-money that would be better invested in a larger selection of filters.
