Ekuqaleni kuka-2021, emva kwezizukulwana ezithathu zophuculo, uSony waphehlelela ikhamera yayo engenazipili, iAlpha 1.
Ukukhutshwa kwale khamera kuphawule inkokeli entsha phakathi kothotho lwe-R lwemifanekiso emileyo, uthotho lwe-S lwevidiyo, kunye nothotho lwe-M olulungeleleneyo, lwaba yimveliso engundoqo ngelo xesha.
Ngelixa wonke umntu wayelindele ukuba iAlpha 1 ibe yimveliso eshushu okwethutyana, imeko yatshintsha-ezinye iikhamera zothotho nazo zenze kakuhle kakhulu. Uthotho lwe-M lubone ukonyuka kokusebenza, uthotho lwe-R lufikelele kwisizukulwana salo sesihlanu, iAlpha 7S III yaduma ngenxa yobuntununtunu obuphezulu kunye neempawu zokuvumisa ngeenkwenkwezi, kwaye iAlpha 9 III yebe indawo ebonakalayo kwiAlpha 1 ekupheleni kuka-2023.
Kwiminyaka emine kamva, iflegi entsha kaSony, iAlpha 1 II, ifikile.
Iminyaka Emine Ekwenziweni
Inzwa yeCMOS ibalulekile njengondoqo wekhamera, iguqula zonke iisignali zokukhanya zibe ziimpawu zombane ukwenza iifoto zedijithali.
I-Sony Alpha 1 II iyaqhubeka nokusebenzisa i-50.1-megapixel ye-full-frame ye-Exmor RS BSI inzwa ye-CMOS njengokwandulelayo, i-Alpha 1, imodeli ye-IMX 610.
Ngaphandle kotshintsho kwi-CMOS kwisithuba seminyaka emine, i-Alpha 1 II yokuthatha umfanekiso omileyo ayiphucukanga kakhulu. Ngeemfuno zosombululo oluphezulu, abasebenzisi banokuthembela kwimowudi ye-pixel-shift yokudubula okuninzi, eyaziwa ngokuba “kukunciphisa ukushukuma,” ukuthwebula iifoto ezili-16 kwaye kamva bazidibanise zibe ngumfanekiso onesisombululo esiphezulu malunga ne-199 yezigidi zeepikseli (17,280 x 11,520 pixels).
I-CMOS engatshintshanga inokutsala ukugxekwa, kodwa kukho isizathu-ngoku akukho CMOS inamandla ekhoyo ukuze isetyenziswe ngabathengi.
Ngokwethiyori, i-IMX 610 inokudubula iifoto ze-50mp ze-14-bit RAW kwiifreyimu ezingama-60 ngesekhondi okanye irekhode i-8K 240p 14-bit ividiyo, kwaye i-Alpha 1 II ayifikelelanga kwimida yayo. Isivamvo esifanayo sikwasetyenziswa kwikhamera ye-cinema ye-Sony, i-CineAltaV 2 (ekwaziwa njenge-VENICE 2), ixabisa malunga ne-47800 yeedola. Ukusukela ekukhutshweni kwayo ngo-2021, le khamera ye-cinema isetyenziswe kwiifilimu ezininzi, ngokungathanga ngqo ingqina amandla ayo okusebenza.
Nangona kungekho tshintsho kwi-CMOS, ukudubula okuqhubekayo kwe-Alpha 1 II kuyancomeka, ikwazi ukwenza iifreyimu ezingama-30 ngesekhondi kwi-50.1 megapixels ngaphandle kokucima ubumnyama, ixhasa ukuya kuthi ga kwi-153 yeefoto ze-RAW ezilandelelanayo, kunye nokubala ukuvezwa malunga namaxesha angama-120 ngesekhondi ukuqinisekisa ukuvezwa okuchanekileyo kwiifoto eziqhumayo.
Ndiyabulela kwi-high-speed readout yale CMOS kunye ne-anti-distortion feature evela kwisizukulwana sangaphambili, i-shutter ye-elektroniki ayivelisi umphumo onamandla wokuvala. Ngesantya esikhawulezayo sokuvala isivalo, isivalo sombane sinokuba neenzuzo ngaphezu kwezivalo zoomatshini zemveli kwiimeko ezininzi.
Ukubamba ifoto, ayisiyiyo nje iCMOS; ukusebenza kwe-autofocus kubaluleke ngokulinganayo.
I-Alpha 9 III, ekhutshwe ekupheleni kuka-2023, sele ibonise oovimba bobuchule be-Sony obuqinileyo kwi-autofocus. U-Evan Vucci, umfoti oyintloko we-Associated Press eWashington, DC, othathe ifoto ethi “Trump Fist Pump”, uyisebenzisa njengekhamera yakhe yomsebenzi ngenxa yesakhono sayo esinamandla se-autofocus.
I-Alpha 1 II ixhotyiswe ngamanqaku angama-759 okubona i-autofocus, egubungela malunga ne-92% yendawo yokujonga. Isixa esikhulu sedatha efundwe yiCMOS icutshungulwa ngokukhawuleza ziiprosesa ezimbini zeBIONZ XR. I-algorithm ephuculweyo iqinisekisa i-autofocus ekhawulezayo kunye nokusebenza komkhondo, ukutshixa ngokuthembekileyo kunye nokulandelela izifundo.
Iisetingi zobungakanani beengongoma ekugxilwe kuzo nazo zandisiwe. Ukongeza kwiisayizi zangaphambili ze-S, M, kunye ne-L, i-Alpha 1 II ngoku iquka ubungakanani be-XS kunye ne-XL, evumela abasebenzisi ukuba benze ukhetho olukhawulezayo.
Ukongezwa kwe-chip ye-AI kujongana nokungaphumeleli kwe-Alpha 1 yangaphambili. Idityaniswe kunye neeprosesa ezimbini ze-BIONZ XR, i-Alpha 1 II inokuqaphela ukuma komntu, ukunika ukugxila ngokukhawuleza kunye nokutshixa okuzinzile.
Ukongezelela ekuqondeni abantu, kuphuculwe umlinganiselo wempumelelo yezilwanyana, iintaka, izinambuzane, iimoto, oololiwe neenqwelo-moya, nto leyo eyenza ukuba ukufotwa kweefoto neevidiyo kube bhetyebhetye kuze kuthembeke ngakumbi.
Ngokudubula okunamandla okuqhubekayo kunye nokusebenza okugxilwe, i-fitsha yokudutshulwa kwangaphambili kwi-Alpha 9 III ikhona kwi-Alpha 1 II. Eli nqaku lingathatha imifanekiso ukuya kuthi ga kwisekondi enye phambi kokuba isivalo sicinezelwe.
Kufana nokuba neFoto ebukhoma kwikhamera, evumela abasebenzisi ukuba baphephe ukuzisola ngexesha eliphosiweyo, bebonelela “ngesicombululo sokuzisola.”
Ngexesha lokusasaza kunye nevidiyo, iflegi ye-mirrorless Alpha 1 II, exhotyiswe nge-CMOS efanayo neCineAltaV 2, iqhayisa ukusebenza kwevidiyo eyomeleleyo.
I-Alpha 1 II inokudubula ukuya kuthi ga kwi-8K 30p 10-bit 4:2:2 okanye 4K 120p 10-bit 4:2:2 ividiyo. Xa udubula i-4K 30p okanye i-24p kwimowudi ye-Super 35, ihambisa imifanekiso ephuma kwi-5.8K i-oversampling, ibonelela ngomgangatho womfanekiso owaneleyo kwiimfuno ezahlukeneyo zokudala.
Umzimba uxhasa iigophe ze-S-Log ezihambelana neekhamera ze-cinema zobuchwephesha. Ijiko le-S-Log 3 le-gamma linokurekhoda ngaphezulu kweendawo ezilishumi elinesihlanu zokumisa kuluhlu oluguquguqukayo, oluhambelana ngokulula nomfanekiso oshukumayo ngeCineAltaV 2, FX9, kunye nezinye iikhamera zecinema, ukwenza lula ukuhamba komsebenzi emva kwemveliso.
Kwabaqalayo, i-S-Log inokuba ngumceli mngeni ukuyiqonda. I-Alpha 1 II ixhasa ukungeniswa ngaphandle kwe-LUTs zabasebenzisi abali-16 ukuze bajongwe kwangaphambili, inciphisa ubunzima bokusebenzisa iigophe zokuhlelwa kombala.
Ukuba i-S-Log ayihlangabezani neemfuno zomsebenzisi, i-Alpha 1 II ikwaxhasa ukudibanisa izixhobo zokurekhoda zangaphandle nge-HDMI port kumzimba, ikhupha ividiyo ye-16-bit Raw format kwiirekhodi zangaphandle. Oku kubonelela ngomgangatho womfanekiso ophantse walahleka, unikezela indawo yohlengahlengiso olubalulekileyo kwimveliso yasemva kokuxhasa imizamo yokuyila.
Ngokumalunga noyilo, iAlpha 1 II ilandela ifilosofi yoyilo lukaSony. Ubume obupheleleyo buhlangene kwaye buchanekile, kunye nomzimba we-matte omnyama we-magnesium alloy obonakala usulungekile kwaye womelele, unika imvakalelo ebambekayo eyomeleleyo kunye nokuqina okugqwesileyo kunye nokhuseleko.
I-Alpha 1 II inobunzima be-743 grams kuphela. Uyilo lwayo lokubamba olunzulu lunciphisa ubunzima besandla kunye nokudinwa ngexesha lokusetyenziswa okwandisiweyo.
Ngaphakathi kwindandatho ye-orange lens mount, i-Alpha 1 II ibonisa inkqubo ye-5-axis stabilization, ifikelela kwi-8.5 yokumisa ukuqina komfanekiso ophakathi kunye ne-7.0 yokumisa imbuyekezo ye-peripheral yokuqinisa umfanekiso, ukuqinisekisa ukucinga okucacileyo phantsi kweemeko eziphezulu.
Ngokucacileyo, i-Alpha 1 II ibandakanya imowudi yozinzo ephuculweyo, ebonwe okokuqala kwi-Sony ZV-E1, iphucula uzinzo ngaphezulu kwe-30%. Eli nqaku livumela ikhamera yeflegi ukuba isebenze "njengekhamera yesenzo," nangona ingafumaneki xa kufotwa kwi-8K okanye kwiifreyimu eziyi-120 ngesekhondi okanye ngaphezulu.
Ukongeza, umzimba uxhotyiswe ngesikrini esifanayo se-4-axis multi-angle flip njenge-Alpha 9 III, okwenza kube lula ukuthatha iifoto kunye neevidiyo nakweyiphi na i-engile.
Ngokuphathelele kwiindawo zokubeka amakhadi, zombini iindawo zokubeka kwi-Alpha 1 II zixhasa ifomati yekhadi le-CFExpress A4.0 yamva nje, enezantya zokubhala ezidlula i-3GB / s, eyi-2 ukuya ku-2.5 ngokukhawuleza kune-CFexpress 2.0. Xa uphonononga iifoto, iAlpha 1 II ivumela ufundo olulandelelanayo olungenamthungo lweefoto ezigcinwe kuwo omabini amakhadi.
Ixabiso elisemthethweni leSony Alpha 1 II limalunga ne-6,565 yeedola, kwaye yakhutshwa ngokusemthethweni ekuqaleni kukaDisemba ka-2024.
Incopho yoMfanekiso: Ithetha ukuthini?
Kukho iqhula elihamba ngolu hlobo:
"Ukusebenzisa ngokupheleleyo amandla eekhamera zanamhlanje, unokufuna ukurekhoda isilwanyana sasendle esibaleka kwilokhwe yomtshato phantsi kweMilky Way kwisavannah yaseAfrika kwezona vidiyo ziphakamileyo."
Ngelixa ivakala kungenangqondo, ibonakalisa ngokwenene imeko yangoku yeekhamera zeflegi.
Kanye njengokuba iBugatti ichaza ibhenchmark yeemoto ezinkulu ezinesantya esigqithileyo kunye nokusebenza, uthotho lweAlpha 1 lirhamncwa elisebenzayo. phantse akukho mntu unokutyhala kwimida yayo kuzo zonke iinkalo. Esi sikhundla sithetha ukuba sisebenzela abasebenzi befilimu abaqeqeshiweyo okanye abafoti abaneemfuno ezigqithisileyo, kwaye ixabiso layo eliphantse libe yi-50,000 RMB (malunga ne-6,565 yeedola) liqinisekisa oku.
Ngoko ke, ngaba le khamera, ebonakala ingafikeleleki kubantu abaqhelekileyo, inako nayiphi na intsingiselo?
Ndiyakholwa ukuba kunjalo.
Ngoku sikwixesha elibalulekileyo kwimbali yokufota-ngaphezulu kwekhulu leminyaka emva kokuqalwa kwayo, ukufota kwe-smartphone kungene kwintengiso ngokuphatheka kwayo kunye ne-algorithms enamandla, ukwenza ukuba iifoto zifikeleleke ngakumbi kunangaphambili.
Ukungena kwee-smartphones kucinezele imakethi yekhamera kule minyaka ilishumi idlulileyo, kodwa ukusuka kwelinye imbono, iye yaqinisa yonke indawo yokufota ngokutsala inkitha yabadlali abatsha.
Ikhamera kunye neenkampu ze-smartphone ziye zasuka kwinkcaso yokuqala ukuya kwinqanaba lokudityaniswa kunye nokufunda. Iikhamera zibandakanya imifanekiso encediswa yi-AI, ngelixa ii-smartphones zifunda isayensi yemibala kubavelisi beekhamera. Ukuphumelela kweteknoloji yenkampu nganye kunokukhuthaza kwaye yalathise enye.
Amathuba emifanekiso abe nobutyebi obungenasiphelo.
Ukubuyela kwizixhobo ezithile, i-Sony Alpha 1 II, le "incopho yemifanekiso," ikude lee kufunwa ngabantu abaqhelekileyo, kodwa siyazifuna-ezi zixhobo zikude zikhulisa iteknoloji yokucinga.
