He 12mm ka mamao o ka mauna M12, ʻo ia ka mamao ma waena o ka flange kau (ke apo metala e hoʻopili ai i ka lens i ke kāmela) a me ka ʻike kiʻi.Hiki i kēia mamao pōkole ke hoʻohana i nā lens liʻiliʻi a me ka māmā, e kūpono ana i nā ʻōnaehana kamepiula paʻa a paʻa.
Hoʻohana maʻamau ka mauna M12 i kahi pilina pili e hoʻopaʻa i ka lens i ke kino kamera.Hoʻopili ʻia ka lens ma luna o ka pahupaʻikiʻi, a ʻo nā kaula e hōʻoia i kahi paʻa paʻa a paʻa.ʻIke ʻia kēia ʻano mauna no ka maʻalahi a me ka maʻalahi o ka hoʻohana.
ʻO kahi pono o ka mauna M12 ʻo ia ka laulā ākea me nā ʻano lens like ʻole.Nui nā mea hana lens e hana i nā lens M12, e hāʻawi ana i kahi ākea o ka lōʻihi a me nā koho aperture e kūpono i nā pono kiʻi like ʻole.Hoʻolālā maʻamau ʻia kēia mau lens no ka hoʻohana ʻana me nā ʻike kiʻi liʻiliʻi i loaʻa i nā pahu kiʻi paʻi, nā ʻōnaehana nānā, a me nā mea hana ʻē aʻe.
C mauna
ʻO ka mauna C he mauna lens maʻamau i hoʻohana ʻia ma ke kahua o nā kiʻi wikiō ʻoihana a me nā kiʻi kiʻiʻoniʻoni.Ua hoʻokumu mua ʻia e Bell & Howell i nā makahiki 1930 no nā kiʻi kiʻiʻoniʻoni 16mm a ma hope i hāpai ʻia e nā mea hana ʻē aʻe.
He 17.526mm ka mamao o ka mauna C, ʻo ia ka mamao ma waena o ka flange kau a me ka ʻike kiʻi a i ʻole ka mokulele kiʻiʻoniʻoni.Hiki i kēia mamao pōkole ke maʻalahi i ka hoʻolālā ʻana o nā lens a hoʻohālikelike ʻia me kahi ākea o nā lens, me nā lens prime a me nā lens zoom.
Hoʻohana ka mauna C i kahi pilina pili e hoʻopili i ka lens i ke kino pahupaʻi.Hoʻopili ʻia ka lens ma luna o ka pahupaʻikiʻi, a ʻo nā kaula e hōʻoia i kahi paʻa paʻa a paʻa.He 1-inihi ke anawaena o ka mauna (25.4mm), he mea li'ili'i ia i ka ho'ohālikelike 'ia me nā pu'u lens 'ē a'e i ho'ohana 'ia i loko o nā pūnaewele kamera nui.
ʻO kekahi o nā pōmaikaʻi nui o ka mauna C ʻo ia ka versatility.Hiki iā ia ke hoʻokomo i nā ʻano lens like ʻole, me nā lens kiʻiʻoniʻoni 16mm, nā lens format 1-inihi, a me nā lens liʻiliʻi i hoʻolālā ʻia no nā pahu kiʻi paʻi.Eia hou, me ka hoʻohana ʻana i nā mea hoʻololi, hiki ke kau i nā lens mauna C ma nā ʻōnaehana kamera ʻē aʻe, e hoʻonui ana i ka laulā o nā lens i loaʻa.
Ua hoʻohana nui ʻia ka mauna C i ka wā ma mua no nā kiʻi paʻi kiʻiʻoniʻoni a hoʻohana mau ʻia i nā kiʻi kiʻi kiʻi kiʻi hou, ʻo ia hoʻi ma ka ʻoihana ʻenehana a me ka ʻepekema kiʻi.Eia nō naʻe, i nā makahiki i hala iho nei, ua ʻoi aku ka nui o nā puʻu lens ʻē aʻe e like me ka mauna PL a me ka mauna EF i nā kiʻi kiʻiʻoniʻoni ʻoihana ma muli o ko lākou hiki ke mālama i nā mea ʻike nui a me nā lens kaumaha.
Ma ke ʻano holoʻokoʻa, ʻo ka mauna C he mau lens koʻikoʻi a maʻalahi hoʻi, ʻoi loa i nā noi kahi e makemake ʻia ai ka compactness a me ka maʻalahi.
CS mauna
ʻO ka mauna CS he mauna lens maʻamau i hoʻohana mau ʻia ma ke kahua o ka nānā ʻana a me nā kāmera palekana.He hoʻonui ia o ka mauna C a ua hoʻolālā kūikawā ʻia no nā kāmera me nā ʻike kiʻi liʻiliʻi.
Loaʻa i ka puʻu CS ka mamao kikoʻī flange like me ka mauna C, ʻo ia ka 17.526mm.'O ia ho'i, hiki ke ho'ohana 'ia nā lens mauna CS ma nā kāme'a mauna C ma o ka ho'ohana 'ana i ka mea ho'opili mauna C-CS, akā, 'a'ole hiki ke kau pololei 'ia nā lens mauna C ma nā kāme'a mauna CS me ka ho'ololi 'ole ma muli o ka lō'ihi o ka mamao o ka mauna CS.
ʻOi aku ka liʻiliʻi o ka mauna CS ma mua o ka mauna C, e ʻae ana i ka nui o ka manawa ma waena o ka lens a me ka ʻike kiʻi.Pono kēia wahi ʻokoʻa no ka hoʻokipa ʻana i nā mea ʻike kiʻi liʻiliʻi i hoʻohana ʻia i nā pahu kiʻi kiaʻi.Ma ka hoʻoneʻe ʻana i ka lens mai kahi mamao aku, ua hoʻopaʻa ʻia nā lens mauna CS no kēia mau mea ʻike liʻiliʻi a hāʻawi i ka lōʻihi kikoʻī kūpono a me ka uhi.
Hoʻohana ka mauna CS i kahi pilina pili, e like me ka mauna C, e hoʻopili i ka lens i ke kino kamera.Eia naʻe, ʻoi aku ka liʻiliʻi o ke anawaena o ka mauna CS ma mua o ka mauna C, me ke ana ʻana he 1/2 iniha (12.5mm).ʻO kēia liʻiliʻi liʻiliʻi kekahi hiʻohiʻona e hoʻokaʻawale i ka mauna CS mai ka mauna C.
Loaʻa nui nā lens mauna CS a hoʻolālā ʻia no ka nānā ʻana a me nā noi palekana.Hāʻawi lākou i nā ʻano lōʻihi a me nā koho lens e hoʻokō i nā pono nānā like ʻole, me nā lens ākea ākea, nā lens telephoto, a me nā lens varifocal.Hoʻohana maʻamau kēia mau lens i nā ʻōnaehana kīwī kaapuni pani (CCTV), nā pahu kiʻi wikiō, a me nā noi palekana ʻē aʻe.
He mea nui e hoʻomaopopo ʻaʻole kūpono nā lens mauna CS me nā kāmeʻa mauna C me ka ʻole o kahi adapter.Eia nō naʻe, hiki ke hoʻohuli ʻia, kahi hiki ke hoʻohana ʻia nā lens mauna C ma nā kāmera mauna CS me ka mea hoʻopili kūpono.
