In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. SpecificationThread (inner diameter): 82mmMade of metalColor: blackPackage included:82mm tele metal lens hood x1Compatible with: all lens with 82mm filter sizeSigmaAf 24-70mm f2.8 if ex dg hsmAf 100-300mm f/4.0Af 20mm 1.8 ex dg asp rf fisheyeAf 10-20mm 3.5 ex dc hsmAf 24-105mm 4.0 dg os hsmCanonEf 16-35mm f/2.8l usmTs-e 24mm 3.5 l ii tilt/shiftEf 24-70mm 2.8 ii l usmKonicaMinolta af 300mm f/4 apo gTamronSp af 28-105mm f2.8Sp af 24-70mm 2.8 di vc usdOlympus:Zuiko digital ed 150mm f/2Nikon:500mm f/8 nikkorSamyang lens: T-s 24mm 3.5 ed as umcZeiss zf lens distagon t* 21mm 2.8Zeiss zf.2 lens distagon t* 18mm 3.5Zeiss zf.2 lens distagon t* 21mm 2.8PentaxPentax lens smc fa 645 33-55mm 4.5Pentax lens smc fa 645 35mm 3.5 al if (26910)Pentax lens smc fa 645 55-110mm 5.6 (26765)Leica lens summarit-s 35mm 2.5 asph
