Ukubeka ikhamera engabonakaliyo ngekhamera kwisivivinyo esishushu.
Ndiyakwazi ukuvula i-A7Rii kunye ne-pixel peep. Ndiyakwazi ukuthetha ngesityalo ngokumalunga nesakhelo esipheleleyo kwi-4k. Pixel binning. EF adapters. ISO uqhathaniswa neA7S. Kodwa bonke abantu benze oko.
Ndifuna ukuthetha nge-Sony A7Rii esetyenziswa kwenye yeemeko ezinzima kunokwenzeka. Umtshini wensimbi. Ukusebenza ngokugcwele, ukutshisa okutshisa, ukuzalisa uthuli. Ndingacinga ukuba u-Sony akazange akhangele ikhamera yayo entsha ye-flagship esebenzayo kwindawo enjalo.
I-Steel Dynamics Inc. yenye yezona zivelisi zentsimbi ehamba phambili. I-Columbus yabo, i-MS mini-mill ithatha i-scrap kwaye iyayibuyisela kwakhona kwimoto (nangaphezulu) insimbi yebakala kubaxhasi kwilizwe lonke.
I-SDI ithatha i-scrap, iyancibilika kwisithando somlilo esingu-3,000 ° F, iyakwenza iinkqubo eziphezulu kwiqondo lokushisa. Usebenziso olushushu, olunzima oluvelisa uthuli oluninzi kunye namathuba amaninzi amanqaku amangalisayo.
Inkampani yam, i-Broadcast Media Group, Inc., Ivelisa amavidiyo ambalwa kwi-SDI equka ukubhala inkqubo yokwenza insimbi. Isiko sikhulu, ngeendlela ezininzi kunye nokuhamba ezininzi. Sawutyhila umfanekiso wokuqala kunye neCanon C300 kunye neC500. I-A7Rii ibonakala ngathi ikhamera efanelekileyo eneenyawo ezincinci ukugqiba ukukhangela amahlumela.
Sifake i-A7Rii kunye ne-Metabones EF ukuya kwi-adapter ye-E (inguqulelo 4) kwaye ufake i-Canon 24-70 f / 2.8 isondeza kuso. Sakhela iphrofayili yombala esekelwe kwisitokisi PP4 ukuya kumdlalo osondeleyo wesiqhelo sethu seCanon.
Sasebenzisa i-DSC One Shot umbala we-Art Adams ukuze udibanise iikhamera ezimbini. Sithatha uphawu lwe-HD-SDI ngaphandle kwe-C300 kunye ne-HDMI uphawu ukusuka kwi-A7Rii kwaye sibaleka kwi-Convergent Design Odyssey 7Q ebonakalayo ene-screen vectorscope eyenziwe. Kwimizuzu engamashumi amabini kamva, sasisondele, singagqibekanga, simele.
Xa umbala wekhamera uhambelana, ungenanto ekhadini le-SD kuyo, ngokukhenketha ngokukhawuleza kwithayitha kunye nebhetri ehlawulweyo, konke esikufunayo kukukufumanisa indlela yokuxhasa ikhamera ngaphandle kokulahlekelwa yinto yethu encinane yefom. I-Manfrotto monopod ifanele i-bill.
Imibuzo yam malunga nokusebenzisa i-A7Rii:
- Ikhamera yayiya kufumana njani ukutshisa kakhulu kunye nothuli?
- Izimo zokukhanyisa zahluka. Umfanekiso uza kubamba njani ngo-2000 + ISO?
- Ngaba i-footage iyazinza kwi-monopod kunye ne-5 axis IBIS edityanisiweyo?
- Ngaba ibhetri iya kubamba? (Ndathabatha ezimbini.)
- Ngaba umbala womdlalo okhoyo unemifanekiso ngaphandle komsebenzi omkhulu?
- Ngaba ndiyakwenza ukutshintsha kwimenyu ye-Canon-ukuya ku-Sony intsingiselo ngaphandle kokuhlambalaza i-shotty?
Ndandilandela ukusekwa kwevidiyo kule nqaku ekulu: http://www.erwinvandijck.com/nieuws/optimized-video-settings-sony-a7r2, eyenziwa ngosuku ngaphambi kokudubula kwaye sasihamba.
Indawo engqongileyo kwintsimbi yayinzima ukuthetha ubuncinci. Isithando somlilo sikhulu kwaye sisondele kwi-3,000 ° F. Ubushushu obuncitshisiweyo buqhubhisa ubushushu obunzulu ukuya kwi-120 ° F - 135 ° F ukuya kwii-100 ukuya kweenyawo. Ingqungquthela yothuli kwindawo yomsebenzi yanika indawo i-action movie movie.
Sawutshaya iB-roll, kunye neziqeshana ezingekho ngaphezu kwe-3: 00. Uninzi lwamaphetshana lwaluku: 30 -: 45 ububanzi. Sigcina iskrini seLCD esongezwa kumzimba kwaye sibhalwa kwikhadi le-SD kwi-4K UHD 100mbps. Sasisityalo kwisithuba seeyure ezingama-2. Sokucima ikhamera ukugcina ibhetri xa usuka kwindawo kwaye uyifake kwisikhwama ukwenzela ukunciphisa ukutshiswa kwothuli.
Sasingenalo ukuvala ukutshatyalaliswa kweshushu. Ndikulindele uhlobo oluthile lokuphala kwamanzi kwiimeko ezinzima, kodwa akukho nto eyenzekayo. Okumangalisayo.
Imiqathango yokukhanya yayiyintlobo ehlukeneyo, ukuthetha ubuncinci. I-lane ye-Canon f2.8 yanceda kakhulu, kodwa ulungelelaniso kunye nokukhanya kwe-A7Rii kwakukhulu. Sidubula kwi-ISO engu-200 ukuya ku-2000 ngaphandle kwesandi esichasayo. Ikhamera ithatha iinkcukacha zethunzi, izitye eziqingqiweyo kunye nento ephakathi. Sazikhethela ukudubula i-SLog2. Iphrofayili yombala esiyakhayo ibonakala enkulu ngaphandle kwekhamera kwaye ngezinye izihlandlo ezincinci ezithintekayo kwi-Speedgrade.
Ndiyakuthanda ukudubula kunye neC300 yam kwi-monopod, kodwa phantse ufikelele kwi-Warp Stabilizer ukuze uphumelele iziphumo. Ngaphandle kwe-IS lens, sisafumana ukunyakaza okufutshane. I-Sony 5 axis stabilization iye yahlaziya ukuhlaziywa. Ngaba iyakwazi ukubamba?
Impendulo emfutshane- yebo. Impendulo ende- iyamangalisa. Andizange ndikholelwe ukuba i-IBIS yazinzisa njani imifanekiso kunye neelensi ezingekho phantsi kwezityalo ezingenakho ukuzinza kwe-lens-based. Uninzi lwamanqaku angasetyenziselwa-alukho ukucwangciswa okongezelelweyo okanye ukuzinza.
Amandla ayexhalabisa emva kokufunda ezinye iimpendulo. Ndilethe iikiti ezimbini zinikezelwa ngamabhethri ngexabiso elipheleleyo. Njenge-backup, ndinezitena zamandla ze-USB kwibhegi ngencambo encinci ukunika amandla ikhamera ngokusebenzisa i-USB port. Sifanele silethe loo mizuzu engama-90 kwisiguqu. Ikhono lokusebenzisa kwi-bhallethi yebhetri ze-USB kwi-pinch inkulu. Kodwa ubomi bebhetri bomthonyama bebuhlungu,
Ngaba sikwazi ukufanisa iphepha elikhoyo ngaphandle komsebenzi omkhulu? Ngokuqinisekileyo. Kodwa kungekho ngaphandle kweminye imivumba. I-A7Rii kwi-4k yayinamandla ngaphezu kwe-1080 HD kwii-Canon, njengoko ungalindela. Kwakumangalisa ukuba ucoceko iinkcukacha zazisombulula. I-colorimetry yayisondele kwaye amnyama amanyaniswa ngokukhawuleza kwi-Speedgrade. Ikhamera entsha yekhamera kakuhle. Enyanisweni, yinqumle ngakumbi kunokuba ndithembele.
Ngaba ndiyakwazi ukulungelelanisa kwimenyu ye-Sony phakathi kompompo onzima? Ewe, kodwa ..., njengawo wonke umntu, ndifuna ukukwazi ukwenza imephu yekhowudi kwiqhosha lokukhulula. Kwaye ndandisoloko ndingena kwimenyu ukutshintshana phakathi kwesakhelo esipheleleyo kunye ne-APC. Ndingayihlawula imali ukuze ndikwazi ukufikelela kulo kumgca weqhosha elilodwa.
Ndiyamangaliswa kakhulu kule khamera. Yona ikhamera ye-DSLR engcono kakhulu esinayo. Yiyo yokuqala ikhamera yefom yefom endiyiva ngayo inokuthabatha umthwalo womsebenzi kwii-Canon zethu.
Andiyithandi i-LCD ye-fold (ngaphandle kokuba umfanekiso ulungile). Uvakalelo olunzima kwaye lukhuni kum. Olunye lwemimiselo yoluhlu kunye neqhosha lomsebenzi alunangqiqo. Ubomi bebhetri abuhle kakhulu.
Kodwa ikhamera emangalisayo. I-Panasonic yam GH4 iya eBay nanini nanamhla. Kwaye i-Canon 5DM3 ikhangele i-nervous kwi-shelf ngokwayo.
Le khamera ikwenze ukuba ndicinga kwakhona into eyenziwa ngu-Sony. I-A7Rii yenze ndivuyiswe ngo-Sony kwakhona.
