Kuyika kamera yoyaka kalilole yotentha kwambiri pamayeso otentha kwambiri.
Ndikhoza kugwiritsa ntchito mawonekedwe a A7Rii ndi pixel peep. Ndikhoza kukamba za mbeu ndi zolemba zonse mu 4k. Pixel binning. EF adapters. ISO kufanana ndi A7S. Koma wina aliyense wachita zimenezo.
Ndikufuna kulankhula za Sony A7Rii yomwe ikugwiritsidwa ntchito mmodzi mwa malo ovuta kwambiri. Mphero yachitsulo. Mphero yowonjezera yowonjezera, yotentha, yodzaza fumbi. Ndikuganiza kuti Sony sanaganizirenso kamera yawo yatsopano yowonongeka pamagwiritsidwe ntchito.
Steel Dynamics Inc. ndi imodzi mwa otsogolera zitsulo omwe akutsogolera dzikoli. Columbus wawo, MS mini-mill amatenga zidutswa ndikuzibwezeretsanso ku magalimoto (ndi kupitirira) zitsulo zamakono kwa makasitomala kudera lonselo.
SDI imatenga zidutswa, zimayisungunula pansi pa ng'anjo ya 3,000 F, imayendetsa pa kutentha komweko, kenaka imaigwiritsa ntchito muzitsulo zotchinga. Ndi ntchito yotentha, yovuta yomwe imapanga fumbi lambiri komanso mwayi wodabwitsa wa masewero.
Kampani yanga, Broadcast Media Group, Inc., Ikupanga mavidiyo angapo a SDI omwe akuphatikizapo kulembera ndondomeko yowonjezera. Malowa ndi aakulu, ndi masitepe ambiri komanso kuyenda kwakukulu. Tinajambula chithunzi choyamba ndi Canon C300 ndi C500. A7Rii ankawoneka ngati kamera yabwino yomwe ili ndi mapazi pang'ono kuti atsirize kujambula.
Tinakonza ma A7Rii ndi Metaboni EF ku E adapter (tsamba 4) ndikuyika zojambula za Canon 24-70 f / 2.8. Tinapanga mbiri yamtundu wodalirika pogwiritsa ntchito katundu PP4 kuti tiyandikire kwambiri maonekedwe athu a kanon.
Tinagwiritsa ntchito tchati chachikulu cha DSC One Shot kuti tigwirizane ndi makamera awiri. Tinajambula chizindikiro cha HD-SDI kuchokera ku chizindikiro cha C300 ndi HDMI kuchokera ku A7Rii ndipo tinawathamangitsa ku Convergent Design Odyssey 7Q yokhala ndi ma vectorscope okwanira. Mphindi makumi awiri kenako, tinali pafupi, osasintha, timayanjana.
Pogwiritsa ntchito kamera, sungani ndondomeko ya SD mkati, mitsulo yowonongeka yowonongeka ndi batiri, zonse zomwe tinkafunikira ndikuti tiwone momwe tingathandizire kamera popanda kutaya mawonekedwe athu ang'onoang'ono. Manfrotto monopodi amatha kulembetsa ndalamazo.
Mafunso anga okhudza kugwiritsa ntchito A7Rii:
- Kodi kamera ikanatha bwanji kutentha ndi fumbi?
- Kuunikira kunali zinthu zosiyanasiyana. Kodi chithunzichi chidzakwaniritsidwa bwanji pa 2000+ ISO?
- Kodi mndandandawo ukhoza kukhala wosasunthika pa monopod ndi mpikisano wa 5 wa IBIS wowonongeka?
- Kodi batriyo idzagwira? (Ndinatenga awiri.)
- Kodi mtunduwo umagwirizana ndi masewera omwe alibe ntchito yambiri?
- Kodi ndingasinthe kusintha kuchokera ku menyu ya Canon-ku Sony tanthawuzo popanda kutsegula mfuti?
Ndinatsatira kujambula kwa kanema kuchokera ku nkhani yaikulu iyi: http://www.erwinvandijck.com/nieuws/optimized-video-settings-sony-a7r2, yomwe inkachitika tsiku lisanafike mphukira ndi kutali.
Chilengedwe chomwe chili pafupi ndi ng'anjo zinali zovuta kunena pang'ono. Tanjo ndi yaikulu ndipo ili pafupi ndi 3,000 ° F. Kutentha kwake kunapangitsa kuti kutentha kwafike kufika 120 ° F - 135 ° F mpaka mamita 100 kutali. Dothi la phulusa kuntchito linapereka chowonetsero cha kanema.
Ife tinamuwombera B-roll, ndi zithunzi zosaposa 3:00. Zowonjezera zambiri zinali mu: 30 -: 45 mitundu. Tinasunga chithunzi cha LCD kuchokera ku thupi ndikulembera ku khadi la SD pa 4K UHD 100mbps. Tinali mumunda kwa maola oposa awiri. Titseka kamera kuti tisawononge bateri pamene tikusamuka kuchoka ku malo ndikuyika mu thumba kuti tipewe kufotokozera fumbi.
Sitinathe kutsekedwa kwachitsulo kamodzi. Ndinali kuyembekezera mtundu wina wa kutentha kwakukulu muzovuta, koma palibe chomwe chinachitika. Zosangalatsa.
Zinthu zowala zinali zosiyana, kunena pang'ono. Lamulo la Canon f2.8 linathandiza kwambiri, koma chigawo ndi kuwala kwa A7Rii zinali zabwino. Tidawombera ku ISO 200 mpaka 2000 popanda phokoso losavomerezeka. Kamera inajambula chithunzi cha mthunzi, chitsulo chosungunuka ndi chirichonse chiri pakati. Tinasankha kuti tisaponyedwe SLog2. Maonekedwe a mtundu amene timamanga amawonekera bwino kuchokera mu kamera ndipo nthawi zina amawombera pang'ono ku Speedgrade.
Ndimakonda kukwera ndi kuwombera ndi C300 yanga, koma nthawi zonse ndimatha kufika ku Warp Stabilizer kuti ndiwononge zotsatira. Ngakhale ndi ma lens, timatengeka pang'ono. The Sony 5 axis stabilization yatenga ndemanga zovuta. Kodi zingatheke?
Yankho lalifupi- inde. Yankho lalitali- zodabwitsa. Sindinakhulupirire kuti IBIS yakhazikika bwanji ndi zida zopanda malire zopanda lens. Zambiri mwazithunzi zingagwiritsidwe ntchito monga-zilibe NTCHITO zina zowonjezera kapena zowonjezereka.
Mphamvu inali yodandaula mutatha kuwerenga ndemanga zina. Ndabweretsa zida ziwirizi zimapereka mabatire ndi zonse. Pofuna kubwezera, ndinali ndi njerwa yamagetsi ya USB mu thumba ndi chingwe chaching'ono kuti ndipatse kamera kupyolera podoko la USB. Tinafunika kutulutsa mphindi 90 pamphepete. Mphamvu yogwiritsa ntchito mabatire a USB mu pinch ndi abwino. Koma moyo wa batri wamba unali wokhumudwitsa,
Kodi timatha kufanana ndi masewera omwe alipo popanda ntchito yambiri? Mwamtheradi. Koma osati popanda zikhomo. A7Rii pa 4k anali akuthwa kuposa 1080 HD kuchokera ku Canons, monga momwe mungayembekezere. Zinadabwitsa kuti ndondomekoyi idasinthidwa. Mitunduyi inali yoyandikana ndi yaying'ono yomwe inali yofanana ndi Speedgrade. Njira yatsopano yamera kamera. Kwenikweni, izo zinadula bwino kuposa momwe ine ndimayembekezera.
Kodi ndingathe kusintha mazenera a Sony pakati pa mphukira yovuta? Inde, koma ... Ine, mofanana ndi wina aliyense, ndikufuna kuwona mapu ojambula ku batani lomasula. Ndipo nthawi zonse ndimalowa mndandanda kuti ndizisintha pakati pazithunzi zonse ndi APC. Ndikanakhala ndikulipira ndalama kuti ndifike ku izi pamapeto pa batani limodzi.
Ndine wokondwa kwambiri ndi kamera iyi. Ndiyo kamera yabwino ya DSLR yomwe tili nayo. Ndiyo kamera yoyamba kamera kamene ndikuganiza kuti ikhoza kugwira ntchito kuchokera ku Canon.
Sindimakonda LCD yopuma (ngakhale fano ili yabwino). Ndizovuta kwambiri komanso kumverera kosavuta kwa ine. Zina mwazomwe mndandanda wamasewera ndi ntchito ya batani sizingakhale zomveka. Moyo wa batri si wabwino kwambiri.
Koma ndi kamera yosangalatsa. Panasonic yanga GH4 ikupita ku eBay tsiku lililonse tsopano. Ndipo Canon 5DM3 ikuyang'ana mantha pang'ono pa alumali palokha.
Kamera iyi yandichititsa kuganizira zomwe Sony akuchita. A7Rii yandipangitsa kusangalala ndi Sony kachiwiri.
