Kungase kuthathe unomphela kwabanye, kodwa ngemva kweminyaka emi-5 yokulinda, u-Sony ubuyekeze umndeni wakhe wamakhamera aklanyelwe ikakhulukazi abathwebuli bevidiyo: I-Sony A7S III. Ikhamera yezibani nezithunzi engibe nethuba lokuba nayo ezandleni zami, futhi namuhla ngizokutshela mayelana nolwazi lwami ngemva kokuyizama.
I-Sony A7S III, ukuhlaziywa kwevidiyo:
Umklamo
Ake ngikubeke esimweni ngaphambi kokuba ngiqale ukukhuluma ngale khamera entsha. Ngibe umsebenzisi wamakhamera we-Sony iminyaka emi-4. Amamodeli amaningana womabili uhla lwe-APS-C nomndeni we-Full Frame yalo mkhiqizi adlule ezandleni zami. Ngalesi sizathu, lapho ngikhipha i-A7s III entsha ebhokisini layo, ngaba nomuzwa wokuba neyami i-A7 III enamavithamini.
Naphezu kokufana kwazo, kusobala ukuthi umgwamanda waleli lungu elisha unjalo ezinkulu futhi eziqinile. Umzimba onokubambelela osivumela ukuthi sibambe ikhamera siqine kakhulu kunezizukulwane ezedlule. Ukwakheka kwezinkinobho nokudayela kuyafana nokuku-Sony A7R IV. Mayelana nalokhu, umehluko ocacile kuphela utholakala enkinobho yokurekhoda, manje enkulu kakhulu futhi itholakala kuphaneli yenkinobho ephezulu. Okuthile thina esizinikezele ukubukela ividiyo siyakwazisa kakhulu.
Kodwa uma thina basebenzisi bakwa-Sony kufanele sijabule ngoshintsho lomzimba, imonitha. Iningi lethu, ikakhulukazi thina esiziqophile, sacela ukuthi kushintshwe isikrini ukuze sibe ukugoqwa okungu-100% hhayi isisombululo esiphakanyiswe amakhamera afana ne-a6600. Ngakho-ke kubonakala sengathi umenzi uzilalele izicelo zethu futhi manje sesizilalele imonitha esingakwazi ukuyizungezisa, siyizungezisa futhi siyinyakaze ngokweqiniso ngokuthanda kwethu. Lokhu futhi kwengeza iphuzu ukuphepha okwengeziwe kusukela, manje singakwazi ukushintshanisa ukuqapha futhi sibeke isikrini ngaphakathi ukuze sigweme izingozi ngenxa yokushaywa noma imihuzuko engenzeka.
Emzimbeni wonke ngeke sithole izinguquko ezinkulu, okungenani ngeso lenyama. Kuzofanele siqale ukudalula amathreyi afakwe uphawu yomzimba wale A7S III ukuqhubeka nokubona izindaba:
- Ngakwesobunxele sithola izixhumi ezijwayelekile zamahedfoni nemakrofoni, i-microUSB, i-USB-C futhi, njengento entsha kule modeli, isixhumi. I-HDMI egcwele. Okuthile okuzobaluleka ngemininingwane esizoyibona esigabeni sokuqoshwa kwamavidiyo.
- Ukusuka ngezansi sizoba nokufinyelela ku-slot yebhethri. Lapha singabeka eyodwa yohlobo I-Sony NP-FZ100, okusinikeza ukuzimela okukhulu kakhulu kune-Sony NP-FW50 yezizukulwane ezedlule. Ibhethri esengivele ngikwazile ukuyihlola isikhathi eside ku-A7 III yami futhi esebenza kahle ngendlela emangalisayo futhi esivumela ukuthi rekhoda futhi uthathe izithombe amahora ambalwa ngaphandle kwezinkinga eziningi.
- Ngakwesobunxele sinethreyi yezinkumbulo, kulokhu, kuzodingeka sihambe ukuze sivule ithreyi. Futhi, ngokwenza lokhu, sizokwazi ukubona uhlelo olusha lwamakhadi amaningi njengoba le A7S III ikwazi ukusebenzisa. Amakhadi we-SD "ejwayelekile" njengezintsha I-CFexpress Uhlobo A. Inkumbulo ebiza ngokungenangqondo okwamanje, kodwa ngezinga lokubhala / lokufunda elingafika ku-700 Mb/s.
Njengoba nginitshelile ekuqaleni kwalesi sigaba, izinguquko u-Sony azisebenzisile ezingeni lomzimba kule khamera yizo kanye ebengizidinga. Umuntu omdala owazana nabasebenzisi bakwa-Sony, onama-ergonomics angcono, avalwe ngazo zonke izindlela futhi ekugcineni, unalelo qapha eligoqayo abaningi bethu ababelidinga.
"Isilo" sasebusuku sevidiyo
Mayelana nenzwa, okuningi bekunamahemuhemu kule minyaka engu-5 mayelana nokucaciswa, amanani ozimele, ama-codec kanye neminye imingcele. Izinguquko ezibikezele ukulungiswa okungenzeka kwe-6K noma i-8K kanye nenani elikhulu lama-megapixel. Futhi cha, ngokuphambene nalokho, sisenakho ukurekhoda okungu-4K okuphezulu futhi a Inzwa engu-12 megapixel. Impumelelo noma ukudumazeka? Kuya ngokuthi ubukeka kanjani.
Lo nyaka ka-2020 kube unyaka wokungabi nazibuko nokuqoshwa ngezinqumo eziphezulu. Isibonelo sicacile kithi kuCanon R5 nge-RAW yayo ku-8K. Futhi u-Sony kungenzeka angabhejeli ekufinyeleleni ukulungiswa okuphezulu kodwa, ngaphandle kokungabaza, akaphoxi ngalokho akunikezayo.
Kungani ama-megapixel angu-12 kuphela?
Kungenzeka ukuthi uzibuza lo mbuzo ngalesi sikhathi. Uhlamvu oluhambisana negama lale khamera lubhekisela ku- "Sensitivity", okungukuthi, ekuzweleni kwe-ISO ekwaziyo ukufinyelela kukho, ukufinyelela amanani asuka ku- 80 – 409.600 ISO.
Lokhu kusivumela ukuthi siguqule ubusuku bube yimini ngokoqobo. Ukufinyelela amanani aphezulu okuzwela kuzokwenza isithombe singabi namsebenzi ngokulinganayo njengezinye izindlela eziningi emakethe. Kodwa, engingakutshela khona ukuthi nge-A7S III uzokwazi ukusebenza ngaphandle kwezinkinga eziningi ngamavelu aphezulu kunamanye.
Incazelo yezobuchwepheshe yalokhu ukuthi kungenzeka ukuthi, ngenxa yalelo nani eliphansi lama-megapixel. I izithombe onesibopho lokuqoqa ukukhanya inzwa kukhona usayizi omkhulu futhi, ngakho-ke, "ukumelana nomsindo" kwalezi kukhulu.
Umbala owengeziwe wokurekhodwa kwakho
Le A7S III iyakwazi ukuqopha ividiyo ngaphakathi 4K ngesilinganiso esiphezulu esingu-120 fps futhi, okubalulekile, ngokujula kombala we 10 izingcezu kanye nesampula yombala 4:2:2. Le datha yakamuva yokujula izoba yindinganiso kokubili ku- entsha XAVC YEBO codec, esihlinzeka ngekhwalithi ephezulu kakhulu yokurekhoda yangaphakathi, njengamanye amakhodekhi nezindlela. Okuthile okufanele ukwazi ukuthi, uma sehlisa isixazululo FullHD singathola ukuqopha ku I-240 fps uma besidinga ikhamera ehamba kancane.
Njengoba bese ngishilo, iqiniso lokuthi le modeli ihlanganisa i-HDMI ephelele emzimbeni wayo izosizuzisa kakhulu esigabeni esisodwa. Futhi yilokho, ngokusebenzisa ukuqapha kwangaphandle, le khamera iyakwazi ukurekhoda Ividiyo RAW ekulungisweni kwe-4K nokushona kombala okungu-16-bit. Ngeshwa, njengoba singenayo enye yalezi zisetshenziswa zokurekhoda zangaphandle, asikwazanga ukuhlola lesi sigaba. Kodwa uma imiphumela yokurekhoda yangaphakathi isivele imangalisa, ingaba ngcono kuphela.
Ngaphandle kokungabaza, esingakuzuza ngokurekhoda ngale khamera kuyamangalisa. Ukuthi ekugcineni sibe nolwazi oluthe xaxa ngemibala kanye namaphrofayili ezithombe ze-Sony (I-Cinema, i-Slog ne-HLG, phakathi kwabanye) sivumele ukuthi sithinte kabusha okurekhodiwe kwethu kakhulu ekukhiqizeni okuthunyelwe, ngaphandle kokwesaba ukukulimaza ngokushesha uma senza izinguquko eziphoqelelwe kakhulu.
Endabeni yami, ngisebenzisa i-A7 III, ngangivame ukurekhoda ku-Slog2, HLG noma Cine4 kuye ngokuthi bengikudingani esimweni ngasinye. I-Slog3 yinto engigcine ngingayisebenzisi, njengoba umsebenzi wangemuva kokukhiqiza wawuyinkimbinkimbi kakhulu futhi kulula ukuphetha ngokonakalisa isithombe. Kodwa-ke, manje njengoba sinolwazi oluthe xaxa ngale modeli, i Iphrofayili ye-Slog3 kunengqondo kakhulu ezimeni lapho ubeka phambili ukuthola ibanga elikhulu eliguqukayo futhi kulula ukusebenza nalo.
Ukuqiniswa kwevithamini kanye nokugxila
Okuhambisana nakho konke lokhu, inzwa yale khamera ine-5-axis stabilization esesivele siyibonile kwamanye amamodeli omkhiqizo. Futhi, njengokwengeza, a Imodi esebenzayo ye-SteadyShot. Lokhu akuyona into engaphezu kokuzinza kwedijithali okwenza a inzwa yokunqampuna a 1,1. Okuthile okungasho lutho kodwa lokho kuwuthuthukisa kakhulu umphumela wokugcina. Lokhu kuzinza okuthuthukisiwe kungenziwa kusebenze kusukela ku- amamenyu yekhamera okuthi, ngendlela, zihlelwe kabusha futhi zathuthukiswa ku-A7S III.
Olunye ushintsho olukhulu maqondana nokuqoshwa kwevidiyo, uma kuqhathaniswa ne-A7 III yami, ngilubone emininingwaneni emi-2 emincane enginika impilo:
- ukurekhoda okungenamkhawulo: Ngenhlanhla, njengoba sesivele sibonile ku-Sony a6600, le modeli ayinawo umkhawulo ocasulayo wemizuzu engama-30 ekurekhodweni kwevidiyo. Ngakho-ke, into kuphela "engasimisa" kuzoba ibhethri noma isitoreji.
- ukugxila kweso okuqhubekayo: lolu hlobo lokugxila yinto ebesivele sinabo ekuthwebuleni izithombe kodwa, ekurekhodweni kwevidiyo, kuyinto entsha kulolu hlu. Kwengezwe ku- super fast focus isivinini kulawa makhamera, kwenze kube yisidingo kulabo basebenzisi abaziqopha njengama-vlogger. Noma, kunjalo, kunoma yimuphi umthwebuli wevidiyo ongafuni ukulahlekelwa ukugxila nganoma yisiphi isikhathi.
Isithombe
Uma ngaphambilini ubuwazi umndeni wakwa-S walawa makhamera akwa-Sony, uzokwazi ukuthi awagqami kahle esigabeni sezithombe. Lokhu kungenxa kakhulu yalawo ma-megapixel ayi-12 ayindlala phakathi kweminye imininingwane.
Naphezu kokuzinikela ngokusemthethweni kuvidiyo, njengento yokuzilibazisa (futhi ngezinye izikhathi emsebenzini) Ngithanda kakhulu ukuthatha izithombe. Futhi, kulesi sigaba, kufanele ngisho ukuthi ukusebenzisa le khamera kunginikeze inhlonipho enkulu. Kodwa, ngemva kwala masonto okuhlolwa, konke lokho kungabaza sekuqedwe ngokuphelele.
izithombe zesampula
Izithombe engikwazile ukuzithatha nazo zisezingeni eliphezulu kakhulu, phakathi nosuku nalapho kuwa ukukhanya. Lokho kuzwela kwe-ISO "okwengeziwe" esinakho kuvidiyo nakho kukhona ezithombeni, ngakho-ke, ukuphathwa komsindo kungaphezu kokulunga ezimeni ezimbi zokukhanya.
Into ebengingakakutsheli ngayo kuze kube manje imayelana neyakhe i-visor, okungenakho okunye futhi okungaphansi kwalokho Amaphuzu we-9.437.184. I-elementi okwamanje emi njengesitholi sokubuka se-elekthronikhi esingcono kakhulu esidalelwe amakhamera angenazibuko kuze kube manje.
Uma ufuna ikhamera ezothatha izithombe ezingeni eliphezulu kakhulu, lokhu kungase kungabi inketho ekufanele kakhulu. Kodwa-ke, kimina kubonakala sengathi singakwazi ukuthatha izithombe ezinhle kakhulu ukuthi, zokunyathelisa ezincane noma ezithunyelwe ezinkundleni zokuxhumana, zingaphezu kokwanele.
Ikhamera engakholeki ngentengo ephezulu
Isikhathi sesifikile sokuthi ngikutshele iziphetho zami ngemuva kokuhlola i-Sony A7S III. Leli lungu elisha lomndeni womkhiqizi wamakhamera kungenzeka lingasiniki isinqumo esiphezulu emakethe, kuze kube manje sonke sivumelana. Kodwa, ngokwamathuba akho, sinezinketho ezingcono kakhulu.
Inani elikhulu lolwazi lombala, elihambisana namaphrofayili ezithombe ukuze uthole ububanzi obuguquguqukayo obukhulu kakhulu futhi, vele, ukwazi ukuqopha yonke into nge-4K ku-120 fps. Konke lokhu kwenza kube ukubheja okuhle kakhulu kithina ebesivele singabasebenzisi bamakhamera akwaSony, nakulabo abafuna ukugxumagxuma.
Kodwa konke bekungeke kube kuhle futhi, njengakunoma iyiphi inketho, kunephuzu eliphikisanayo kule khamera: intengo yayo. Okwamanje singathenga i-Sony A7S III kuwebhusayithi yomkhiqizi I-4.200 euro. Ingabe kufanelekile ukukhokha imali engaka ngale khamera? Ngokubona kwami, yebo. Kodwa ngiyaqonda ukuthi ingaphandle kwesabelomali sabaningi abazimele, ikakhulukazi kulezi zikhathi. Uma kunjalo, isincomo sami ukuthi ulinde izinyanga ezimbalwa ukuze uthole okunikezwayo okuthakazelisayo okwenza intengo yakho ibe phansi.
