Inokuba ithathe unaphakade kwabanye, kodwa emva kweminyaka emi-5 yokulinda, uSony uhlaziye usapho lwayo lweekhamera ezenzelwe ngokukodwa abathwebuli bevidiyo. I-Sony A7S III. Ikhamera yezibane kunye nezithunzi endiye ndafumana ithuba lokuba nazo ezandleni zam, kwaye namhlanje ndiza kukuxelela malunga namava am emva kokuzama.
I-Sony A7S III, uhlalutyo lwevidiyo:
Uyilo
Makhe ndikubeke kwimeko phambi kokuba ndiqale ukuthetha ngale khamera intsha. Ndingumsebenzisi weekhamera ze-Sony iminyaka emi-4. Iimodeli ezininzi zoluhlu lwe-APS-C kunye nosapho lweSakhelo esiPheleleyo salo menzi zidlule ezandleni zam. Ngesi sizathu, xa ndithatha i-A7s III entsha kwibhokisi yayo, ndaba nemvakalelo yokuba ne-A7 III yam eneevithamini.
Nangona zifana, kucacile ukuba umzimba weli lungu elitsha inkulu kwaye yomelele ngakumbi. Umzimba obambekayo osivumela ukuba sibambe ikhamera ngokuqinileyo kunezizukulwana zangaphambili. Ubume bamaqhosha kunye nokucofa kuyafana nakwi-Sony A7R IV. Kule nkalo, umahluko ocacileyo kuphela ufumaneka kwiqhosha lerekhodi, ngoku likhulu kakhulu kwaye libekwe kwipaneli yeqhosha eliphezulu. Into esiyixabisa kakhulu abo bethu bazinikele kwividiyo.
Kodwa ukuba thina basebenzisi beSony kufuneka sonwabe malunga notshintsho lomzimba, sisijongi. Uninzi lwethu, ngakumbi abo bethu bazirekhodayo, bacele utshintsho kwiscreen ukuze sibe yi-100% ukusonga hayi isisombululo esicetywayo ziikhamera ezifana ne-a6600. Ke kubonakala ngathi umenzi umamele izibongozo zethu kwaye ngoku siyenzile imonitha esinokuthi siyijikelezise, siyijikelezise kwaye siyishukumise ngokwenyani ngokuthanda kwethu. Oku kongeza inqaku ukhuseleko olongezelelweyo ukusukela, ngoku siyakwazi ukujikelezisa esweni kwaye sibeke isikrini ngaphakathi ukuphepha iingozi ngenxa yezithonga okanye imikrwelo enokwenzeka.
Kuwo wonke umzimba asiyi kufumana utshintsho olukhulu, ubuncinci ngeliso lenyama. Kuya kufuneka siqale ukutyhila iitreyi ezinokutywinwa lomzimba wale A7S III ukuqhubeka nokubona iindaba:
- Kwicala lasekhohlo sifumana iziqhagamshelo eziqhelekileyo ze-headphones kunye nemakrofoni, i-microUSB, i-USB-C kwaye, njengento entsha kule modeli, isinxibelelanisi. IHDMI epheleleyo. Into eya kuba yimfuneko kwiinkcukacha esiya kuyibona kwicandelo lokurekhoda ividiyo.
- Ukusuka ngezantsi siya kuba nokufikelela kwi-slot yebhetri. Apha sinokubeka enye yohlobo I-Sony NP-FZ100, esinika ukuzimela okukhulu ngakumbi kune-Sony NP-FW50 yezizukulwana ezidlulileyo. Ibhetri esele ndikwazi ukuyivavanya ixesha elide kwi-A7 III yam kwaye isebenza ngokumangalisayo kwaye isivumela ukuba rekhoda kwaye uthathe imifanekiso iiyure ezininzi ngaphandle kwengxaki ezininzi.
- Kwicala lasekhohlo sinetreyi yeenkumbulo ezinokuthi, kule meko, kuya kufuneka sishukume ukuze sivule itreyi. Kwaye, ngokwenza oku, siya kuba nakho ukubona inkqubo entsha yamakhadi amaninzi kuba le A7S III iyakwazi ukusebenzisa. Amakhadi e-SD "eqhelekileyo" njengezintsha CFexpress Uhlobo A. Imemori ebiza kakhulu okwangoku, kodwa ngereyithi yokubhala / yokufunda ukuya kuthi ga kwi-700 Mb/s.
Njengoko benditshilo ekuqaleni kweli candelo, utshintsho olwenziwe nguSony kumgangatho womzimba kule khamera yeyona nto bendiyifuna. Umntu omdala omaziyo kubasebenzisi be-Sony, kunye ne-ergonomics engcono, etywinwe ngandlela zonke kwaye, ekugqibeleni, inalo lisongwayo elifunekayo uninzi lwethu.
"Irhamncwa" lasebusuku levidiyo
Ngokumalunga ne-sensor, kuninzi kuye kwathethwa ngamahemuhemu kule minyaka ye-5 ngokwemigaqo, iireyithi zesakhelo, iicodecs kunye nezinye iiparameter. Utshintsho oluqikelele ngesisombululo esinokwenzeka se-6K okanye i-8K kunye nenani elikhulu leemegapixels. Kwaye hayi, ngokuchaseneyo noko, sisenayo ukurekhoda kwe-4K ephezulu kunye Inzwa ye-megapixel eyi-12. Impumelelo okanye ukuphoxeka? Kuxhomekeke kwindlela okhangeleka ngayo.
Lo ka-2020 ibe ngunyaka wokungabi nazipili kunye nokurekhoda kwizigqibo eziphezulu. Umzekelo ucacile kuthi kwiCanon R5 kunye neRAW yayo kwi8K. Kwaye uSony usenokungabheji ekufikeleleni kwisisombululo esiphezulu kodwa, ngaphandle kwamathandabuzo, ayidanisi koko ikunikayo.
Kutheni iimegapixels ezili-12 kuphela?
Usenokuba uyazibuza lo mbuzo okwangoku. Ileta ehamba negama lale khamera ibhekisa ku "Sensitivity", oko kukuthi, kubuntununtunu be-ISO ekwaziyo ukufikelela kuyo, ukufikelela kumaxabiso aqala ukusuka. 80 - 409.600 ISO.
Oku kusivumela ukuba sibuguqule ngokoqobo ubusuku bube yimini. Ukufikelela kumaxabiso aphezulu ovakalelo kuya kwenza umfanekiso ungabi namsebenzi ngokulinganayo njengezinye iindlela ezininzi kwintengiso. Kodwa, into endinokukuxelela yona kukuba nge-A7S III uya kuba nakho ukusebenza ngaphandle kweengxaki ezininzi kumaxabiso aphezulu kunamanye.
Ingcaciso yobuchwephesha yokuba oku kunokwenzeka kukuba, ngenxa yelo nani lisezantsi leemegapixels. I iifoto uxanduva lokuqokelela ukukhanya kwi-sensor ubukhulu obukhulu kwaye, ke ngoko, "ukuxhathisa ingxolo" kwezi mkhulu.
Umbala owongezelelweyo kwiirekhodi zakho
Le A7S III iyakwazi ukurekhoda ividiyo kwi I-4K kubuninzi be-120 fps kwaye, okubalulekileyo, ngobunzulu bombala we 10 ungazama kunye nesampuli yombala 4:2:2. Ezi data ubunzulu zamva nje iya kuba umgangatho zombini kwi entsha XAVC EWE codec, esinika owona mgangatho uphezulu wokurekhoda wangaphakathi, njengakwezinye iikhowudi kunye neendlela. Into ekufuneka uyazi kukuba, ukuba sisehlisa isisombululo Egcweleyo singafumana ukurekhoda 240 fps ukuba sifuna ikhamera ecothayo nangakumbi.
Njengoko besenditshilo, into yokuba le modeli ibandakanya i-HDMI epheleleyo emzimbeni wayo iya kusinceda kakhulu kwicandelo elinye. Kwaye yile nto, ngokusebenzisa ukubeka esweni kwangaphandle, le khamera iyakwazi ukurekhoda Ividiyo eRAW kwisisombululo se-4K kunye nobunzulu bombala we-16-bit. Ngelishwa, ekubeni singenaso esinye sezi zixhobo zokurekhoda zangaphandle, asikwazanga ukuvavanya eli candelo. Kodwa ukuba iziphumo zokurekhoda zangaphakathi sele ziyamangalisa, zinokuba ngcono.
Ngaphandle kwamathandabuzo, oko sinokukuphumeza ngokurekhoda ngale khamera kuyamangalisa. Ukuba ekugqibeleni sinolwazi olungakumbi lombala kunye neeprofayile zemifanekiso kaSony (Cinema, Slog kunye HLG, phakathi kwabanye) sivumele ukuba siphinde sithinte iirekhodi zethu ezininzi kwimveliso yeposi, ngaphandle kokwesaba ukuyonakalisa ngokukhawuleza ukuba senza ukuguqulwa okunyanzeliswayo.
Kwimeko yam, usebenzisa i-A7 III, ndandisebenzisa ukurekhoda kwi-Slog2, i-HLG okanye i-Cine4 kuxhomekeke kwinto endiyidingayo kwimeko nganye. I-Slog3 yayiyinto endiye ndaphela ndingayisebenzisanga, kuba umsebenzi we-post-production wawunzima kakhulu kwaye kwakulula ukuphelisa umfanekiso. Nangona kunjalo, ngoku njengoko sinolwazi oluninzi ngale modeli, i Iprofayile ye-Slog3 yenza ingqiqo ngakumbi kwiimeko apho ubeka phambili ukufumana uluhlu olukhulu olutshintshayo kwaye kulula ukusebenza ngalo.
Uzinzo lweVithamini kunye nokugxila
Ukukhapha konke oku, inzwa yale khamera ine-5-axis stabilization esele siyibonile kwezinye iimodeli zophawu. Kwaye, njengokongeza, a Imowudi esebenzayo yeStadyShot. Oku akukho nto ngaphandle kozinzo lwedijithali olwenza a isityalo soluvo a 1,1. Into engabalulekanga kodwa ephucula kakhulu isiphumo sokugqibela. Olu phuculo lozinzo lunokwenziwa lusebenze kwi iimenyu yekhamera leyo, ngendlela, zicwangcisiwe zaphuculwa kwi-A7S III.
Olunye utshintsho olukhulu malunga nokurekhodwa kwevidiyo, xa kuthelekiswa ne-A7 III yam, ndiyibonile kwiinkcukacha ezincinci ezi-2 ezithi, kwimeko yam, zindinike ubomi:
- ukurekhoda okungenamkhawulo: Ngethamsanqa, njengoko sele sibonile kwi-Sony a6600, le modeli ayinamda ocaphukisayo wemizuzu engama-30 ekurekhodweni kwevidiyo. Ngoko ke, into kuphela enokuthi "isimise" iya kuba yibhetri okanye ukugcinwa.
- ugxininiso lweliso oluqhubekayo: olu hlobo lokujolisa yinto ebesele sinabo ekufotweni kodwa, ekurekhodweni kwevidiyo, yinto entsha kolu luhlu. Yongezwe kwi isantya sogqaliselo esikhawulezayo kwezi khamera, yenza kube yinto eyimfuneko kwabo basebenzisi bazibhalayo njengevlogger. Okanye, ngokuqinisekileyo, nakweyiphi na i-videographer engafuni ukuphulukana nokugxila nangaliphi na ixesha.
Ukufota
Ukuba ubusazi ngaphambili usapho lwe-S kwezi khamera ze-Sony, uya kwazi ukuba azigqamanga ngokuthe ngqo kwicandelo lemifanekiso. Oku kubangelwe ikakhulu kwezo megapixels zili-12 zinqabileyo phakathi kwezinye iinkcukacha.
Ngaphandle kokuzinikela ngokusemthethweni kwividiyo, njengento yokuzonwabisa (kwaye ngamanye amaxesha emsebenzini) Ndikuthanda kakhulu ukuthatha imifanekiso. Kwaye, kweli candelo, kufuneka nditsho ukuba ukusebenzisa le khamera kundinika intlonipho enkulu. Kodwa, emva kwezi veki zovavanyo, onke loo mathandabuzo apheliswe ngokupheleleyo.
iifoto zesampula
Iifoto endiye ndakwazi ukuzithatha kunye nazo zikwizinga eliphezulu kakhulu, kokubili emini naxa kuwa ukukhanya. Uvakalelo "olulongezelelweyo" lwe-ISO esinalo kwividiyo lukwakhona kwiifoto kwaye, ngoko ke, ulawulo lwengxolo lungaphezulu kokuchaneka kwiimeko ezimbi zokukhanya.
Into ebendingekakuxeleli ngayo kude kube ngoku yeyakhe umbukeli, engenanto eyongezelelweyo kwaye akukho nto ingaphantsi Amanqaku e-9.437.184. Into ekungoku nje ime njengeyona ndawo ibalaseleyo yokujonga i-elektroniki eyenzelwe iikhamera ezingenazipili ukuza kuthi ga ngoku.
Ukuba ujonge ikhamera yokuthatha iifoto kwinqanaba eliphezulu, oku kusenokungabi lolona khetho lufanelekileyo kuwe. Nangona kunjalo, kum kubonakala ngathi sinokuthatha iifoto ezintle kakhulu ezinokuthi, kushicilelo oluncinci okanye ukuthunyelwa kwiinethiwekhi zentlalo, zingaphezulu ngokwaneleyo.
Ikhamera engakholelekiyo ngexabiso elikhulu
Lifikile ixesha lokuba ndikuxelele izigqibo zam emva kokuvavanya i-Sony A7S III. Eli lungu litsha losapho lomenzi weekhamera unokungasiniki esona sisombululo siphezulu kwintengiso, ukuza kuthi ga ngoku sonke sivumelana. Kodwa, kumathuba akho, sinokhetho olungcono.
Isixa esikhulu solwazi lombala, olukhatshwa ziiprofayili zemifanekiso ukufumana olona luhlu lunamandla lokuguquguqukayo kwaye, ngokuqinisekileyo, ukukwazi ukurekhoda yonke into kwi-4K kwi-120 fps. Konke oku kwenza kube ubhejo olukhulu sobabini thina ababesele bengabasebenzisi beekhamera zeSony, kunye nakwabo bafuna ukwenza umtsi.
Kodwa yonke into ayinakulunga kwaye, njengakuyo nayiphi na inketho, kukho indawo ephikisanayo malunga nale khamera: ixabiso layo. Ngoku sinokuthenga i-Sony A7S III kwiwebhusayithi yomenzi 4.200 euro. Ngaba kufanelekile ukuhlawula imali eninzi ngale khamera? Ngokombono wam, ewe. Kodwa ndiyaqonda ukuba iphuma kuhlahlo lwabiwo-mali lwabaninzi abazimeleyo, ngakumbi kula maxesha. Kwimeko apho, isincomo sam kukuba ulinde iinyanga ezimbalwa ukuze ufumane umnikelo onomdla owenza ixabiso lalo libe ngaphantsi.
