Isigaba sokuqala sibhengeza iSchneider-Kreuznach 40-80mm f / 4-5.6 lens

Isigaba sokuqala sibhengeze i-Schneider-Kreuznach 40-80mm f / 4-5.6 lens shutter lens, eyesibini yohlobo lwayo lweekhamera zeefomathi eziphakathi zenkampani.

Kwangoko kwi2014, Isigaba sokuqala sazise i-IQ250, Iilensi zokuqala zomenzi ophakathi kunye nesenzi mfanekiso seCMOS. Inkampani ibuyile ngesinye isibhengezo esineelensi ezintsha ezijolise kuma-645-series shooters. I-Schneider-Kreuznach 40-80mm f / 4-5.6 lens shutter lens ngoku isemthethweni kwaye iyafumaneka kwintengiso.

I-Schneider-Kreuznach 40-80mm f / 4-5.6 ilensi ngoku isesikweni kuyilo lwe-shutter yegqabi kwaye ijolise kwisigaba sokuqala sekhamera zefomathi.

Ifomathi ephakathi ayithandwa kakhulu ngenxa yamaxabiso athintelayo. Nangona umgangatho we-optical awunanto imfutshane ngokumangalisayo, iifomathi eziphakathi zeekhamera kunye neelensi zibiza kakhulu kwaye zinkulu kwaye zinzima.

Injalo imeko yeelensi ezivaliweyo zamagqabi, kunye neendleko zazo zonyuka ngakumbi xa kufikwa kwimodeli yokusondeza. Uninzi lwee-optics ziimodeli eziphambili, kodwa emva kokumiliselwa kwe-75-150mm f / 4-5.6, iSigaba sokuQala sibuyile nenye iyunithi yokusondeza, equka ilensi yeSchneider-Kreuznach 40-80mm f / 4-5.6.

Ilensi evaliweyo yeelensi zemidlalo iincakuba ezininzi zesinyithi ezivulekileyo kwaye zivale xa kuvezwa umfanekiso. Iibhlethi zibizwa ngokuba ngamagqabi kwaye ukuveza kwenziwa ngendlela eyahlukileyo xa kuthelekiswa ne-shutter-shutter shutter.

Olona thuba lukhulu kwi-shutter optics kukuba banokusebenza ngesantya esikhawulezayo sokuvumelanisa i-flash, ukufikelela kwi-1 / 1600th yesibini, ekhawulezayo kakhulu kunale uyifumana kwii-DSLRs eziqhelekileyo okanye iikhamera ezingenazipili.

Ubunzima bokuyilwa kwayo kunye nomgangatho ophezulu wokukhanya kwenza iilensi ezingama-40-80mm f / 4-5.6 ibe yimveliso ebiza kakhulu

Ilensi entsha sisiphumo sentsebenziswano eqinileyo phakathi kweSigaba sokuQala, iSchneider-Kreuznach, neMamiya. Inezinto ze-15 ezahlulwe zangamaqela ali-11, kubandakanya izinto ezimbini ze-aspherical.

Umphathi weSigaba sokuqala utyhile ukuba iinzame ezingaphezulu zibekwe kwi-Schneider-Kreuznach 40-80mm f / 4-5.6 lens shutter lens kunayo nayiphi na enye ilensi eyeza ngaphambi kwale mveliso.

Umphathi weMveliso ePhakamileyo u-Espen Beck uqinisekisile ukuba uyilo lweelensi zoom luyinkimbinkimbi ngakumbi, ngakumbi xa umgangatho we-optical kufuneka ugcinwe kwelona nqanaba liphezulu.

Inkampani kuthiwa "iyazingca kakhulu" ngayo yonke into eyenzekileyo, ke le lens sele ikhona ukuthengwa ngamaqabane ayo kwihlabathi liphela.

Njengoko kuchaziwe apha ngasentla, kuya kubiza kakhulu ngexabiso elimi kwi $ 8,990 e-US kunye ne- € 6,990 eYurophu. Iinkcukacha ezithe kratya ziyafumaneka kwi Iwebhusayithi esemthethweni yesiGaba sokuqala.
