Ikhamera ye-Sony yezinga lokungena egcwele uhlaka olugcwele isibuko iyisilwane ngazo zonke izindlela ezinenzwa yayo yesithombe engu-33-megapixel, ukuqoshwa kwevidiyo okungu-4K60p, kanye nomklamo we-ergonomic.
Ngenkathi u-Sony ekhipha i-a7 IV ngoDisemba, ngempumelelo eqhubekayo ye-a7 III, yayinesidingo esikhulu sokugcwalisa. Umanduleli uphume eminyakeni engaphezu kwemine edlule entwasahlobo ka-2018, kodwa uhlala ungomunye wezinga eliphezulu lokungena eligcwele- amakhamera wefreyimu kokubili isithombe nevidiyo.
Ngama-tweaks athile abalulekile kanye nokuthuthukiswa kwekhwalithi yokuphila, u-Sony wenze i-a7 IV yaba indlalifa efanelekayo esihlokweni sekhamera eyingxubevange engcono kakhulu.
Eminyakeni edlule, u-Sony uzenzele njengenye yezinkampani ezinhle kakhulu zamakhamera angenazibuko. Ithengise amakhamera angenazibuko kakhulu ngo-2021, ngokusho kwe-NPD Group.I-Sony ayikwazi ukufanisa ifa lemboni yeCanon, i-Nikon noma i-Fujifilm, kodwa idlalile. indima enkulu ekwandiseni amakhamera angenazibuko ngochungechunge lwayo lwe-Alpha.
Lonke uhlobo lokudala lunekhamera ye-Alpha, kodwa uchungechunge lwe-a7 luklanyelwe ukwenza konke.I-a7 IV kanye nokwakhiwa kwayo okuguquguqukayo akukwazi ukufana nezithombe ze-a7R IV's 61-megapixel, futhi idlulwa amandla okuqopha ividiyo angu-4K120p we-a7S III. .Nokho, isadlala indima ebalulekile njengendlela ejabulisayo phakathi kwamakhamera amabili achwepheshile.
Okokufaka kungathola ingxenye yendali uma uthenga imikhiqizo ngezixhumanisi ezikulesi sihloko.Sifaka kuphela imikhiqizo ekhethwe ngokuzimela ithimba labahleli bokokufaka.
I-Sony's a7 IV inikeza ikhamera eyingxube emangalisayo engathwebula izithombe ezingama-33-megapixel nevidiyo kufika ku-4K60p.
Kusuka ku-Nikon, ngicabanga ukuthi kuzoba nesikhathi esinzima sokulungisashintshaohlelweni lwe-Sony.Kodwa empeleni kuthathe cishe amahora amabili kuphela ukudlala nge-a7 IV ukwenza izinkinobho nomklamo uwonke uzizwe usekhaya.I-Sony iphonse izinkinobho ezine ezihlelekayo, isondo lokuskrola elenziwe ngendlela oyifisayo, kanye nekhono lokuphinda wenze imephu ye-AF. ON kanye nezinkinobho ze-AEL, kodwa angicabangi ukuthi bengidinga ukushintsha okuningi ukuze ngijwayele ukusetha.Uma kufanele ulungise izilungiselelo, isistimu yemenyu ihleleke kakhulu ngezigaba, okwenza kube lula ukuzulazula ngisho nethani izilungiselelo.
Ezandleni zami ezincane, i-a7 IV iphephe kakhulu futhi ikhululekile ukuyibamba, futhi zonke izinkinobho zizwakala zisendaweni efanele, ikakhulukazi irekhodi.inkinobhoehamba eduze kwenkinobho yokuvala.Izinkinobho ze-joystick nesondo lokuskrola zithinteka kakhulu, okungivumela ukuthi ngiphenye ngokushesha ekuqhumeni kwezithombe ngenkathi ngibuka noma ngilungisa iphuzu lokugxila le manuwali.
Isibonisi esicacisa ngokugcwele singenye yentuthuko enkulu kakhulu ye-a7 IV. Iguquguquka kakhulu kunesikrini esiyinqaba se-pop-up ku-a7 III, futhi singazungeziswa ngo-180 degrees ukuze sibhekane nawe ukuze kube lula ukubhuloga ngevidiyo noma izithombe ozishuthe zona. Ngezithombe eziqinile eziseduze kakhulu phansi, ungaveza isikrini cishe ngamadigri angu-45 ngaphandle kokugoba kabi ukuze ubone ukuthi isithombe sakho sibukeka kanjani.
Isitholi sokubuka se-OLED sihle ngokufanayo.Sikhulu futhi siyakhanya, futhi kuzwakala sengathi ubona cishe isithombe ongasithola lapho uchofoza isivalo.
U-Sony uphinde waklama ukudayela okuncane okusha ngezansi kwemodi yokudayela ukuze ushintshe ngokushesha ezindleleni zesithombe, zevidiyo ne-S&Q (amafushane amamodi anensayo nasheshayo, akuvumela ukuthi urekhode ikhamera edlula isikhathi noma ividiyo ehamba kancane) .Ungakwazi khetha ukuthi yiziphi izilungiselelo ozozigcina lapho ushintsha amamodi noma uhlela izilungiselelo ezithile ukuze zihlukaniswe ngalezo zindlela.Kuwukufakwa okulula, kodwa kuyisici esiveza ngempela uhlobo oluxubile lwe-a7 IV.
Uma kuziwa emandleni e-autofocus, amakhamera akwa-Sony Alpha awanakuqhathaniswa.Okufanayo naku-a7 IV.Ngenxa yejubane nokuphendula kwe-autofocus, kucishe kuzwakale njengokukopela uma uthwebula ngayo.I-Sony ihlomise i-Bionz XR yesizukulwane esilandelayo. Injini yokucubungula isithombe, ekwazi ukubala ukugxila izikhathi eziningi ngesekhondi, ivumele i-a7 IV ukuthi ihlonze ngokushesha ubuso noma amehlo esihloko futhi ikhiye i-autofocus kuyo.
Ngiqiniseka kakhulu nge-a7 IV's autofocus ukuyigcina inamathele esihlokweni, ikakhulukazi uma ngithwebula ngemodi yokuqhuma. Benginokuncane okokufaka okwenziwa ngesandla uma ngithwebula ukugxila kuhlaka oluhle kakhulu. Isikhathi esiningi, bengivele ngivumele i-shutter tear, njengoba ingashaya amafreyimu angu-10 ngomzuzwana;Ngethemba ukuthi ikhamera izogcina isihloko sami sibukhali kukho konke ukuqhuma.
Ngendlela i-A7 IV's face/eye-priority AF inhle ngayo, ngiyakwazi ukugxila ekwakhiweni.Kwesinye isikhathi i-autofocus iyalahleka bese igxila ezintweni ezingalungile, kodwa ihlakaniphe ngokwanele ukubeka kabusha ubuso noma amehlo ukuze ibambe kabusha.Ezifundweni ezingenabo ubuso. , i-a7 IV isakwazi ukuthola isihloko esihloniphekile phakathi kwamaphoyinti ayo angu-759 AF, ngisho nalapho ngithwebula ku-f/2.8.
Kufika kuma-megapixel angu-33 (24.2 megapixels ku-a7 III), kunemininingwane eyengeziwe ongasebenza ngayo lapho unqampuna izithombe, kanye nenye indlela eyengeziwe. Ngihlole i-a7 IV ngelensi ye-Sony engu-$2,200 FE 24-70mm F2.8 GM, ukuze ngikwazi sondeza ukuze ngilungise ifreyimu yami ezimweni eziningi.Ezithombeni okufanele ngizinqamule, kwakusenemininingwane eminingi ekukhetheni okunqampunwe kakhulu.
Ngezitobhi ze-a7 IV ezingu-15 zobubanzi obuguquguqukayo kanye ne-ISO kufika ku-204,800, izimo zokukhanya okuphansi azinakukhathazeka. Umsindo uqala ukubonakala cishe ku-ISO 6400 noma 8000, kodwa kuphela uma uwufuna ngempela. cishe ngeke ngibe nenkinga yokuyiqhumisa kuze kufike ku-ISO 20000, ikakhulukazi uma ulayisha izithombe ku-Instagram noma enye ifomethi encane yenkundla yezokuxhumana. Ibhalansi emhlophe ezenzakalelayo nayo yenze kahle kuzo zonke izigcawu engizibekile, kuhlanganise nokukhanya kwelanga okuqondile. , liguqubele, i-fluorescent yasendlini kanye nezibani ze-incandescent zangaphansi.
Njengoba i-a7 IV iyikhamera ehlanganisiwe, ingakwazi futhi ukuphatha ividiyo, nakuba inezinkinga ezimbalwa.Inzwa inikeza ikhwalithi yevidiyo ecacile efanayo futhi isekela i-10-bit 4:2:2 kuwo wonke amafomethi okurekhoda, okwenza ividiyo kube lula ukucubungula kuyo. okuthunyelwe.I-a7 IV isekela i-S-Cinetone ne-S-Log3, ukuze uthole ukulawula okuningi kokuhlela ngangokunokwenzeka ngokuhlelwa kombala nokulungiswa.Noma ungasebenzisa ukulungiselelwa kwe-Creative Look okungu-10 ukuze unciphise noma yikuphi ukuhlela futhi wenze ukuphila kwakho kube lula.
I-a7 IV's five-axis in-in-body image stabilization yenza amashothi aphathwayo ahloniphekile, kodwa kunemodi esebenzayo etshala kancane ukuze kuthuthukiswe ukunyakaziswa kwekhamera.Ngisho noma ngihamba futhi ngidubula ngaphandle kwe-gimbal ne-monopod, izithombe eziphathwa ngesandla bezizinze ngokwanele;akubukekanga kuphazamisa kakhulu ukulungisa ngenkathi uhlela.
Kukhona izexwayiso eziphawulekayo mayelana namakhono evidiyo ye-a7 IV. Njengoba abaningi bevezile, izithombe ze-4K60p zinqanyuliwe ngempela. Okuphawulekayo kodaba lwe-rolling shutter i-a7 IV ethwala kusukela kumanduleli wayo, kodwa ngaphandle uma ungumthwebuli wevidiyo ochwepheshe, cishe akunandaba.
Ngiyaqonda ukuthi kungani u-Sony ebiza i-a7 IV ngekhamera eyinhlanganisela “yezinga lokungena”, kodwa ithegi yayo yentengo engu-$2,499 (umzimba kuphela) yenza umehluko. kubiza u-$3,499 (umzimba kuphela).Noma kunjalo, ngicabanga ukuthi i-a7 IV ikufanele ngale ntengo, njengoba ilenga nakanjani uma kuziwa ezithombeni nakumavidiyo.
Kumuntu onjengami oshutha kakhulu anganyakazi kodwa afune ukudlala kuvidiyo ngezikhathi ezithile, i-a7 IV iyisinqumo esihle. Angibheki ikhwalithi ephezulu kakhulu yevidiyo, noma izinga lozimele elishesha kakhulu, ngakho ukushutha kufika ku-4K60p kufanele kwanele. , i-autofocus eshesha kakhulu futhi enokwethenjelwa yenza i-a7 IV ibe isidubuli sansuku zonke esihle kangaka.
Sekukonke, ngizwa sengathi ikhamera ye-hybrid yakwa-Sony isishaye enye indlela yasekhaya. Uma ufuna ikhamera enekhono ekwazi ukuphatha izithombe ezimile nevidiyo engaphansi kochwepheshe, i-a7 IV iyisincomo esilula uma intengo ingakuyeki. .
