Muraayadaha muraayadaha indhaha ee Nikon ee dhamaadka-sare si loogu shaqaaleeyo dahaadhka fluorine-ka

Nikon waxaa lagu xantaa inuu ku daro lakab fluorine ah dhammaan muraayadaha indhaha ee telephoto-ka shirkadda, liiska oo ay ku jiraan ugu yaraan shan nooc oo la sheegay in lagu beddelayo laba sano gudahood.

Nikon wuxuu ku dhawaaqay muraayad telephoto cusub badhtamihii Maajo. Muraayadda cusub ee 400mm f / 2.8E FL ED VR wuxuu ku beddelayaa noocii hore mid dahaadh fluorine ah, culeys yar, iyo astaamo kale si kor loogu qaado tayada badeecadan. Si kastaba ha noqotee, qaabkan cusub ayaa ka qaalisan kii ka horreeyay waxayna u muuqataa inay tani tahay waxa saxda ah ee aan ka filan karno Nikon labada sano ee soo socota.

Nikon waxay ku dari doontaa lakab fluorine ah muraayadaha indhaha oo dhan si ay uga dhigto kuwo u adkeysanaya wasakhda, siigada, dufanka, iyo dhibcaha biyaha.

Dhammaan muraayadaha indhaha ee Nikon ee dhammaadka-sare waxay soo bandhigi doonaan daahan fluorine

Shirkadda fadhigeedu yahay Japan ayaa markii ugu horreysay soo bandhigtay daawaha fluorine-ka ee loo yaqaan 'Nikkor 800mm f / 5.6, oo ah muraayad la soo saaray xilligii xagaaga ee 2012.

Foomka labaad ee telephoto optic ah si loogu faano daahan noocan oo kale ah ayaa ah AF-S Nikkor 400mm kor ku xusan 2.8mm f / XNUMXE FL ED VR. Dhammaan optics-yada leh foloraydh fluorine ah ayaa shaqaalaysiin doona magaca "FL" waxayna u muuqataa inaan arki doonno in badan oo ka mid ah oo la bilaabay labada sano ee soo socota.

Ilo gudaha ah ayaa ka warbixinaya in dhamaan muraayadaha indhaha ee Nikon telephoto dhammaantood ay ka muuqan doonaan dahaadhka fluorine-ka iyo in lagu dhawaaqi doono “1-2 sano ee soo socota”.

Nikon si loogu badalo muraayadaha 200mm, 300mm, 500mm, 600mm, iyo 200-400mm laba sano gudahood

Waxa jira shan nooc oo cusub oo wali u baahan in la beddelo ku dhowaad dhammaantood iyaga oo leh "arrimo" culus oo ku saabsan tafaariiqleyda. Liiska waxaa ku jira 200mm, 300mm, 500mm, 600mm, iyo 200-400mm.

Amazon mar dambe ma iibineyso cutubyo cusub oo muraayadda Nikon 200mm f / 2G ah AF-S ED VR II ah, in kasta oo unugyada dib loo cusboonaysiiyay ama la isticmaalay weli la iibsan karo. Intaa waxaa dheer, ka Nikon 500mm f / 4G ED VR AF-S SWM lens dib ayaa loo dalbadaa oo markab buu raacayaa laba ilaa afar toddobaad gudahood markii aad iibsatay.

The Nikon 300mm f / 2.8G AF-S ED VR II muraayadaha indhaha waxaa loo heli karaa qiyaastii $ 5,800, laakiin waxaa jira hal cutub oo keliya oo harsan.

Sida for 200-400mm f / 4G AF-S SEM SIC ED HADDII VR II iyo 600mm f / 4G ED VR II AF-S SWM muraayadaha indhaha, Amazon wali way iibineysaa, laakiin waxaa jira cutubyo yar oo haray keydka. Iyagu waa moodello qaali ah wayna ka adag yihiin iibintooda, marka macno ma leh in la haysto qaybo aad u tiro badan.

Waa maxay daboolka Nikon ee fluorine-ka?

Nikon waxay leedahay fiidiyoow macluumaad ah oo kusaabsan dahaadhkeeda fluorine ee lagu darayo muraayadaha indhaha 400mm iyo 800mm. Dahaadhkani wuxuu ka kooban yahay dusha sare ee lagu daro wajiga hore ee muraayadaha indhaha oo u rogaya dusha sare ee hydrophobic.

Dahaadhku wuxuu u oggolaanayaa muraayadaha inay dib u celiyaan biyaha, dufanka, wasakhda, iyo walxaha siigada. Qalabka telephoto optics waxaa badanaa isticmaala duurjoogta iyo sawir qaadayaasha isboortiga, taas oo macnaheedu yahay in xaaladaha toogashada mararka qaarkood ay yihiin kuwo qallafsan oo wasakhdu u hoggaansami karto muraayadaha indhaha, taasoo ka dhigeysa muraayadda mid aad u adag in la nadiifiyo.

Mahadsanid, daahan ayaa fududeynaya muraayadaha indhaha si aad u nadiifiso wax badana u sii waara waqti ka dib maxaa yeelay arrimaha dibedda ah ma dhaawaceyso. Intaas waxaa sii dheer, maadaama lagu nadiifiyey si fudud, adeegsadayaashu mar dambe khatar uguma jiraan inay dhaawacaan muraayadaha inta lagu jiro hawsha nadiifinta.
