Ikhamera ye-Sony yenqanaba lokungena elipheleleyo elinefreyimu engenazipili lirhamncwa ngandlela zonke kunye nomfanekiso wayo we-33-megapixel sensor, ukurekhoda kwevidiyo ye-4K60p, kunye noyilo lwe-ergonomic.
Xa u-Sony wakhulula i-a7 IV ngoDisemba, kunye nempumelelo eqhubekayo ye-a7 III yayo, yayinemfuno enkulu yokuzalisa. iikhamera zesakhelo kuzo zombini ifoto kunye nevidiyo.
Ngolunye uhlengahlengiso oluphambili kunye nokuphuculwa komgangatho wobomi, u-Sony wenze i-a7 IV yaba yindlalifa efanelekileyo kwisihloko sekhamera ye-hybrid.
Ukutyhubela iminyaka, uSony uzimise njengenye yezona nkampani zibalaseleyo zekhamera ezingenazipili. Ithengise ezona khamera zingenazipili ngo-2021, ngokweNPD Group.I-Sony ayinakuhambelana nelifa lemveliso yeCanon, iNikon okanye iFujifilm, kodwa idlalile. indima enkulu ekwaziseni iikhamera ezingenazipili ngothotho lwayo lweAlpha.
Lonke uhlobo loyilo lunekhamera ye-Alpha, kodwa uchungechunge lwe-a7 lwenzelwe ukwenza konke.I-a7 IV kunye nolwakhiwo oluguquguqukayo alukwazi ukuhambelana neefoto ze-A7R IV ze-61-megapixel, kwaye zogqweswa yi-a7S III's 4K120p izakhono zokurekhoda ividiyo. .Nangona kunjalo, isadlala indima ebalulekileyo njengendlela eyonwabileyo phakathi kweekhamera ezimbini ezingaphezulu.
Igalelo linokufumana inxalenye yentengiso ukuba uthenga iimveliso ngokusebenzisa amakhonkco akweli nqaku.Sibandakanya kuphela iimveliso ezikhethwe ngokuzimeleyo liqela loHlelo lokuNgenisa.
I-Sony's a7 IV ibonelela ngekhamera engumxube emangalisayo enokudubula iifoto ze-33-megapixel kunye nevidiyo ukuya kuthi ga kwi-4K60p.
Ukuvela ku-Nikon, ndicinga ukuba kuya kubakho ixesha lohlengahlengiso olunzulutshintshakwi-Sony system.Kodwa eneneni kuthathe malunga neeyure ezimbini kuphela ukudlala nge-a7 IV ukwenza amaqhosha kunye noyilo jikelele uzive usekhaya.I-Sony ijule amaqhosha amane enziwe ngokwezifiso, ivili lokuskrola elilungelelanisiweyo, kunye nokukwazi ukuphinda kumephu i-AF. ON kunye namaqhosha e-AEL, kodwa andiqondi ukuba bekufuneka nditshintshe kakhulu ukuze ndiqhele ukuseta.Xa kufuneka udibanise izicwangciso, inkqubo yemenyu icwangciswe kakhulu ngokweendidi, ikwenza kube lula ukuzulazula nokuba ngetoni yetoni. izicwangciso.
Kwizandla zam ezincinci, i-a7 IV ikhuseleke kakhulu kwaye ikhululekile ukuyibamba, kwaye onke amaqhosha aziva ekwindawo elungileyo, ngakumbi irekhodi.iqhoshaesondela kufutshane neqhosha lesivalo.Iqhosha lokudlala kunye namaqhosha evili lokuskrola achuku, endivumela ukuba ndikrobe ngokukhawuleza kwiifoto ngokugqabhuka ngelixa ndijonge okanye ndihlengahlengisa indawo ekugxilwe kuyo.
Umboniso ocaciswa ngokupheleleyo ngomnye wophuculo olukhulu lwe-a7 IV. Iguquguquka ngakumbi kune-pop-up engaqhelekanga yesikrini kwi-a7 III, kwaye inokujikeleziswa ngamadigri angama-180 ukujongana nawe ukwenza i-vlogging lula okanye i-selfies. Ukudubula okuqinileyo kufutshane kakhulu emhlabeni, unokukhupha isikrini malunga ne-45 degrees ngaphandle kokugoba kakubi ukuze ubone ukuba ukudubula kwakho kujongeka njani.
I-OLED viewfinder ilungile ngokulinganayo.Yinkulu kwaye iyaqaqamba, kwaye ivakala ngathi ubona phantse ifoto obuya kuyifumana xa ucofa isivalo.
U-Sony uphinde wayila i-sub-dial entsha ngaphantsi kwemodi yokudayela ngokukhawuleza ukutshintshela kwifoto, ividiyo kunye neendlela ze-S & Q (ezimfutshane kwiindlela ezicothayo nezikhawulezayo, ezikuvumela ukuba urekhode ixesha lokuhamba okanye ividiyo eshukumayo kwikhamera) .Unako khetha ukuba zeziphi izicwangciso ozigcinayo xa utshintshela iindlela okanye udweliso lwenkqubo ethile ukuba yahlulwe kwezo ndlela.Kukubandakanywa okulolu hlobo olulula, kodwa luphawu oluzisa ngokwenene uhlobo oluxubileyo lwe-a7 IV.
Xa kuziwa kwizakhono ze-autofocus, iikhamera ze-Sony ze-Alpha azinakulinganiswa.Kwafanayo kuya kwi-a7 IV.Ngenxa yesantya kunye nokuphendula kwe-autofocus, iphantse ivakale ngathi ukukopela xa idubula nayo.I-Sony ixhobise i-Bionz XR yesizukulwana esilandelayo. Injini yokulungisa umfanekiso, enokubala ukugxila kaninzi ngesekhondi, ivumela i-a7 IV ukuba ibone ngokukhawuleza ubuso okanye amehlo esifundo kwaye itshixe i-autofocus kuyo.
Ndiqinisekile nge-a7 IV's autofocus ukuyigcina incamathele kwisifundo, ngakumbi xa ndidubula kwimowudi yokugqabhuka. Ndinegalelo elincinci lemanuwali xa ndibamba ugxininiso lwesakhelo esigqibeleleyo. Ngamaxesha amaninzi, ndiyeke nje i-shutter tear, njengoko inokubetha iifreyimu ezili-10 ngomzuzwana;Ndiyathemba ukuba ikhamera iya kugcina umxholo wam ubukhali ngalo lonke ixesha lokuqhuma.
Ngendlela elungileyo ngayo i-a7 IV yobuso / i-AF ye-eye-priority, ndiyakwazi ukugxila ekubunjweni.Ngamanye amaxesha i-autofocus iyalahleka kwaye igxininise kwizinto ezingalunganga, kodwa ihlakaniphile ngokwaneleyo ukubeka ubuso okanye amehlo ukuba iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde ibuyele kwizifundo ngaphandle kobuso. , i-a7 IV yayisakwazi ukufumana isifundo esifanelekileyo phakathi kwamanqaku ayo angama-759 AF, nangona ndandidubula kwi-f / 2.8.
Ukuya kuthi ga kwi-33 megapixels (24.2 megapixels kwi-a7 III), kukho iinkcukacha ezithe kratya omawusebenze ngazo xa ucupha iifoto, kunye nenye indlela eyongezelelweyo. Ndivavanye i-a7 IV nge-Sony's $2,200 FE 24-70mm F2.8 GM lens, ukuze ndikwazi. Sondeza ukulungisa isakhelo sam kwiimeko ezininzi. Kuzithonga ebekufuneka ndizinqande, bekusekho iinkcukacha ezininzi kukhetho olunqanyulwe kakhulu.
Nge-a7 IV's 15 yeendawo zokumisa zoluhlu oluguquguqukayo kunye ne-ISO ukuya kwi-204,800, iimeko zokukhanya okuphantsi akukho nto yokukhathazeka ngayo.Ingxolo iqala ukuphawuleka malunga ne-ISO 6400 okanye i-8000, kodwa kuphela ukuba uyifuna ngokwenene. 'Mhlawumbi awuyi kuba nangxaki ukuyibhuqa ukuya kuthi ga kwi-ISO 20000, ngakumbi ukuba ufaka nje imifanekiso kwi-Instagram okanye enye ifomathi encinci yemidiya yoluntu.Ibhalansi emhlophe ezenzekelayo nayo iqhube kakuhle kuyo yonke imiboniso endiyibekileyo, kuquka ukukhanya kwelanga. , amafu, i-fluorescent yangaphakathi kunye nezibane ze-incandescent zangaphantsi.
Ekubeni i-a7 IV ikhamera ye-hybrid, inokusingatha ividiyo, nangona imiba embalwa.Inzwa inika umgangatho ofanayo wevidiyo ocacileyo kwaye isekela i-10-bit 4: 2: 2 kuzo zonke iifomati zokurekhoda, okwenza ividiyo ibe lula ukuyiqhuba. isithuba.I-a7 IV ixhasa i-S-Cinetone kunye ne-S-Log3, ngoko ke ufumana ulawulo lokuhlela kangangoko kunokwenzeka ngokuhlelwa kombala kunye nohlengahlengiso.Okanye ungasebenzisa i-10 yokujonga i-Creative Look presets ukugawula naluphi na ukuhlela kwaye wenze ubomi bakho bube lula.
I-a7 IV ye-five-axis in-body image stabilization yenza ukudubula kwesandla esihloniphekileyo, kodwa kukho imowudi esebenzayo eyenza izityalo zinciphise ngakumbi ikhamera.Naxa ndihamba kwaye ndadubula ngaphandle kwegimbal kunye ne-monopod, i-handheld footage yayizinzile ngokwaneleyo;khange ikhangeleke iphazamisa kakhulu xa uhlela.
Kukho izilumkiso eziqaphelekayo malunga nesakhono sevidiyo ye-a7 IV, nangona abaninzi beye bachaza, imifanekiso ye-4K60p inqanyulwe ngokwenene. Umba ophawulekayo wokuvala i-shutter i-a7 IV ithwala ukusuka kumanduleli wayo, kodwa ngaphandle kokuba ungumdlali wevidiyo oyingcali, akunamsebenzi.
Ndiyasiqonda isizathu sokuba u-Sony abize i-a7 IV ngokuba yikhamera ye-hybrid “entry-level”, kodwa ixabiso layo le-$2,499 (umzimba kuphela) liyawenza umahluko. iindleko $3,499 (umzimba kuphela) .Sekunjalo, ndicinga ukuba i-a7 IV ifanelekile ngeli xabiso, njengoko ixhomekeke ngokuqinisekileyo xa ifika kwiifoto kunye neevidiyo.
Kumntu ofana nam odubula kakhulu emile kodwa afune ukukhe akrobe kwividiyo, i-a7 IV lukhetho olufanelekileyo.Andijonganga mgangatho uphezulu wevidiyo, okanye isantya sefreyimu esikhawulezayo, ngoko ke ukudubula ukuya kuthi ga kwi-4K60p kufanele kwanele.Ngokwenene. , i-autofocus ekhawulezayo kakhulu kwaye ethembekileyo yenza i-a7 IV ibe ngumdubuli omkhulu wemihla ngemihla.
Ngokubanzi, ndivakalelwa kukuba ikhamera ye-Sony ye-hybrid ibethe enye ikhamera yasekhaya. Ukuba ukhangele ikhamera ekwaziyo ukusingatha i-sub-professional stills kunye nevidiyo, i-a7 IV sisincomo esilula ukuba ixabiso alikubeki phantsi. .
