Ukubeka ikhamera engabonakali esibukweni ekuhlolweni okushisayo.
Ngingakwazi ukuvula i-A7Rii ne-pixel peep. Ngingakhuluma ngesitshalo ngokuhambisana nohlaka olugcwele ku-4k. I-Pixel binning. Ama-adapter e-EF. ISO ukuqhathanisa ne-A7S. Kodwa bonke abanye benze lokho.
Ngifuna ukukhuluma nge-Sony A7Rii esetshenziswa kwenye yezinkinga ezinzima kunokwenzeka. Umshini wensimbi. Imishini yokusebenza yensimbi esebenza ngokugcwele, egcwele uthuli. Ngicabanga ukuthi u-Sony akakaze acabange ikhamera yabo entsha ye-flagship esebenzayo endaweni enjalo.
I-Steel Dynamics Inc. ingomunye wabakhiqizi bensimbi abahola phambili. I-Columbus yabo, i-MS mini-mill ithatha iziqephu futhi iyayibuyisela kabusha emotweni (nangaphezulu) insimbi yebanga kumaklayenti ezweni lonke.
I-SDI ithatha isikhala, iyancibilika esithandweni somlilo esingu-3 000 ° F, siyisebenzisela emazingeni okushisa afanayo, bese isenza ibe yensimbi ehlanganisiwe. Kuyinto yokushisa, efuna ukukhiqiza okukhiqiza uthuli oluningi kanye namathuba amaningi okumangaza amavidiyo.
Inkampani yami, i-Broadcast Media Group, Inc., Ikhiqiza amavidiyo ambalwa we-SDI afaka phakathi kokubhala inqubo yokwenza insimbi. Isikhungo sikhulu, sinamazinga amaningi nokuhamba okuningi. Sidubula isithombe sokuqala ne-Canon C300 no-C500. I-A7Rii ibonakala njengekhamera ekahle enezinyathelo ezincane kakhulu ukuqedela ukudubula.
Sifake i-A7Rii nge-Metabones EF kuya ku-E-mount adapter (inguqulo 4) bese ufaka ukusondeza kwe-Canon 24-70 f / 2.8 kuyo. Sakhe iphrofayli yombala yangokwezifiso esekelwe kwisitoko PP4 ukuze sisondelane ngokubuka kwethu i-Canon ukubukeka kwethu.
Sisebenzise ishadi lombala we-DSC One Shot omkhulu we-Art Adams ukufanisa amakhamera amabili. Sithathe isignali ye-HD-SDI ngaphandle kwesignali ye-C300 ne-HDMI evela ku-A7Rii futhi sibagijimela ku-Convergent Design Odyssey 7Q enemifanekiso egcwele ye-screen vectorscope. Ngemuva kwemizuzu engamashumi amabili, sasivalekile, singaphelele, sihambisana.
Njengoba umbala wekhamera ufananisiwe, ungenalutho ikhadi le-SD ngaphakathi, i-zoom yensimbi esheshayo nebhethri ekhokhwayo, konke okudingekayo ukuhlola indlela yokusekela ikhamera ngaphandle kokulahlekelwa isici sethu sefomu elincane. I-Manfrotto i-monopod ivumelane nomthethosivivinywa.
Imibuzo yami mayelana nokusebenzisa i-A7Rii:
- Ikhamera yayiyokwenzeka kanjani ekushiseni okukhulu nangothuli?
- Izimo zokukhanyisa zazihlukahlukene. Isithombe sizoba kanjani ngo-2000 + ISO?
- Ingabe i-footage izobe igxilile kwi-monopod ne-5 axis ye-IBIS edutshulwa ngokuqinile?
- Ingabe ibhethri izobamba? (Ngathatha ezimbili.)
- Ingabe umbala ufanelana nomfanekiso okhona ngaphandle kwemisebenzi eminingi?
- Ngingayenza yini ushintsho kusuka kwimenyu ye-Canon-ingena ku-Sony incazelo ngaphandle kokwesula ukudubula?
Ngilandele ukusethwa kwevidiyo kusuka kulesi sihloko esikhulu: http://www.erwinvandijck.com/nieuws/optimized-video-settings-sony-a7r2, okwenziwa ngosuku ngaphambi kokudubula futhi sasihamba.
Isimo esiseduze nesithando somlilo sasinselele ukusho okungenani. Isithando somlilo sikhulu futhi siseduze no-3 000 ° F. Ukufudumala okushisa kushukumisa izinga lokushisa elingaba ngu-120 ° F - 135 ° F ngamakhilomitha angaba ngu-100. Izinhlayiya zothuli endaweni yomsebenzi zanikeza lesi senzakalo isenzo se-movie senzo.
Sidubule i-B-roll, eneziqeshana ezingekho ku-3: 00. Amashothi amaningi aphakathi kwe: 30 -: 45 ububanzi. Sigcine isikrini se-LCD esandiswe emzimbeni futhi sibhaliswe ekhadini le-SD ku-4K UHD 100mbps. Sasihlala esitshalweni isikhathi esingaphezu kwamahora amabili. Sivimbela ikhamera ukusindisa ibhethri uma sisuka endaweni bese sibeka esikhwameni ukuze sinciphise ukuchayeka uthuli.
Asizange sibe nokuvalwa okuhlobene okushisa okulodwa. Ngilindele uhlobo oluthile lokukhipha ukushisa ngezimo ezinzima, kepha akukho okwenzekile. Okumangalisayo.
Izimo zokukhanya zazihlukahlukene, ukusho okungenani. I-lane ye-Canon f2.8 yasize kakhulu, kodwa ukukhanya kwe-latitude nokukhanya kwe-A7Rii kwakukhulu. Sidubula kusukela ku-200 kuya ku-2000 ISO ngaphandle komsindo ongazwakalayo. Ikhamera ithathe imininingwane yezithunzi, insimbi encibilikisiwe encibilikisiwe nayo yonke into ephakathi. Sakhetha ukudubula i-SLog2. Iphrofayela yombala esiyikhile ibheke okuhle ngaphandle kwekhamera futhi nge-tweaking encane encane e-Speedgrade.
Ngiyakuthanda ukudubula nge-C300 yami kumuntu oyedwa, kepha cishe njalo sifinyelela i-Warp Stabilizer ukuze ubambelele imiphumela. Ngisho ne-IS lens, sisathola ukunyakaza okuncane. I-Sony 5 axis ukuqiniswa ifinyelele ukubuyekezwa kokuhlaselwa. Ngabe ingabe iphakame?
Impendulo emfushane- yebo. Impendulo ende- iyamangaza. Angikwazi ukukholelwa ukuthi i-IBIS iqinisile kangakanani imidwebo ngamalensi angewona abomdabu abangenawo ukuqiniswa kwamalensi. Iningi lezithombe lingasetshenziswa njenge-alikho ukucubungula okunye noma ukuqiniswa.
Amandla kwakukhathazeka ngemuva kokufunda ezinye izibuyekezo. Ngiletha amabhethri amabili anikezwa ngamabhethri ngokugcwele. Njenge-backup, nginezitini zamandla e-USB esikhwameni esinombambo omncane ukwenza ikhamera ngokusebenzisa i-USB port. Kwakudingeka sikhiphe amaminithi angama-90 ehlathini. Ikhono lokusebenzisa ngaphandle kwamabhethri e-USB esithombeni kukhulu. Kodwa impilo yebhethri yendabuko yayidumaza,
Ingabe sikwazi ukufanisa imidwebo ekhona ngaphandle komsebenzi omkhulu? Kulungile. Kodwa hhayi ngaphandle kwamanye ama-caveats. I-A7Rii ngo-4k yayinamandla kune-1080 HD kusukela ku-Canon, njengoba ubungalindela. Kwakumangalisa ukuthi imininingwane ihlanzekile kanjani. I-colorimetry yayinamazinga aseduze namnyama ahambisana ngokufanayo ku-Speedgrade. I-intercut entsha yekhamera kahle kakhulu. Eqinisweni, kunciphisa kangcono kakhulu kunalokho engangiyithemba.
Ngingakwazi yini ukuzivumelanisa nemenyu ye-Sony phakathi kwesibhamu esiyinselele? Yebo, kodwa ... Mina, njengabanye abantu bonke, ngifuna ukukwazi ukufaka imephu yenkinobho yokurekhoda ku-inkinobho yokukhishwa kwe-shutter. Futhi ngangilokhu ngingena kwimenyu ukushintsha phakathi kohlaka olugcwele ne-APC. Ngingakhokha imali ukuze ngifinyelele kulokhu ekuthinteni kwenkinobho eyodwa.
Ngiyakhathazeka kakhulu ngalesi khamera. Yiyona ikhamera ye-DSLR engcono kakhulu esinayo. Kuyinto ikhamera yefomu yokuqala encane engizizwa engayithatha enye yomthwalo wokusebenza kusuka kwi-Canon yethu.
Angithandi i-LCD ephumayo (nakuba isithombe sihle). Ukuzizwa okungenakuqhathaniswa nokwehluleka kimi. Enye imenyu yokuhlelwa kwemenyu kanye nesabelo senkinobho ayinangqondo. Ukuphila kwebhethri akusihle kakhulu.
Kodwa ikhamera emangalisayo. I-Panasonic yami GH4 iya e-eBay nanoma yiluphi usuku manje. Futhi i-Canon 5DM3 ibheka kancane ukwesaba eshalofini ngokwayo.
Le ikhamera ingenze ngicabangisise ukuthi yini eyenziwa ngu-Sony. I-A7Rii ingenze ngijabule nge-Sony futhi.
