Ukuhlaziywa kwePanasonic Lumix DC-GH5

Lo mgca we-hybridi okhutshwe yiPanasonic unawo njengomxhasi wawo wesihlanu kwaye uza ne-20MP yesine inzwa yesithathu kunye neseti enkulu yeempawu zeevidiyo ezityhalela phambili ngakumbi kunangaphambili kwe-GH4.

Umanduleli ngoku lukhetho lwexabiso eliphantsi kubalandeli boluhlu kwaye unokwanela abo banelisekileyo ziimpawu zayo kodwa i-GH5 iyabonakala ngezinto ezinje ngozinzo emzimbeni okanye ividiyo ye-4K eya kuthi ngokuqinisekileyo zingqinele ukuba ukulungele ukuphucula ukuba uza kwenza umboniso bhanyabhanya.

Iimpawu eziqhelekileyo

Sele siyikhankanyile inzwa yesithathu ye-20MP engenayo i-OLPF, inkqubo yokuzinzisa umfanekiso ikwi-axis ezintlanu kwaye iza nenkxaso 'ye-Dual IS 2' kwaye imifanekiso ye-4K ithathwa kusetyenziswa ububanzi benzwa, oko kuthetha ukuba isampulu ukusuka kumfanekiso we-5.1K.

Nazi ezinye zeempawu ngokubanzi:

-I-4K / 30p yangaphakathi ye-10-bit 4: 2: 2 yokubanjwa kwevidiyo
-I-4K / 59.94p kunye ne-50p yokudubula nge-10-bit 4: 2: 2 ukuphuma okanye i-8-bit, 4: 2: 0 yokurekhoda ngaphakathi
- Ividiyo eyi-1080 ukuya kuthi ga kwi-180p, eyenza i-7.5x ishukume kancinci
-I-9 fps yokudubula ngokuqhubekeka ngokuzenzekelayo
-Ukugxininisa phambili kwe-DFD
-Dual UHS II card slots (V60 ilungile)
-I-Autofocus point yolonwabo
- 802.11ac iWi-Fi, i-NFC kunye neBluetooth
-Imowudi yokujonga kwangaphambili yokubeka
-I-Waveform kunye nevectorscope monitors
-Uhlaziyo oluhlawulelweyo lwenza ukuba ukubanjwa kwevidiyo ye-V-LogL kuboniswe kumboniso we-LUT

Ezinye izinto

I-Panasonic ikwaphucule ukusebenza kwekhamera kunye nokuziphatha ngaphandle kweempawu ezongeziweyo nokuba awucwangcisi ukusebenzisa ividiyo ye-4K okanye ezinye izinto ngokukhawuleza, isenokuba ngumbono olungileyo ukuphucula.

Zimbini iindawo zokubeka amakhadi e-SD axhasa amakhadi aphezulu wesantya kwaye ubungakanani obupheleleyo be-HDMI Port eza nenkxaso eyongezelelweyo ifakiwe. Isixhobo se-shutter siyathula kwaye sinokuqengqeleka okungaphantsi kwaye iPhaneli yeLCD ibukhali kakhulu ngescreen sokuchukumisa. Imenyu ikwaphuculwe kwaye ulawulo lubukeka kakhulu kuba kuya kuba lula ukuhlengahlengisa indawo ekugxilwe kuyo.

Uhlaziyo ezimbini ze-firmware sele zibhengeziwe, enye ikhutshwe ngo-Epreli 2017 kwaye enye ngexesha lasehlotyeni. Eyokuqala ifuna ukuzisa i-10-bit 4: 2: 2 1080p ukubanjwa, ngelixa yesibini iza ne-DCI / UHD 4K 4: 2: 2 10-bit yokurekhoda kwi-400Mbps kunye ne-1080 / 60p 4: 2: 2 10 -bit yokurekhoda kwi-200Mbps. Zombini ezi zinto ziya kusebenzisa i-All-Intra compression kunye ne-anamorphic 4K capture nazo ziya kuxhaswa emva koko.

Ividiyo ye-4K kwi-60p

Eli lelona nqaku linomtsalane kwi-GH5 njengoko ngoku ungadubula imifanekiso ye-4K ukuya kuthi ga kwi-59.94p kunye ne-48p okanye i-50p ukuba udubula iPAL. Ukufundwa kwe-sensor epheleleyo kuthetha ukuba i-footage isampulu ukusuka kwi-5.1K kwaye ke ubungakanani bonke benzwa busetyenziselwa iziphumo ezibukhali. Ukurekhodwa kwangaphakathi kunqunyelwe kwisibhozo se-4: 2: 0 ye-IPB encoding ukuya kuthi ga kwi-150Mbps kodwa ukuba ukongeza isishicileli sangaphandle lo mgangatho unokuphakama.

Ukudubula okungu-4K akubeki naliphi na ixesha lothintelo ngenxa yoko kugqwesa kakhulu, kusenza ukhetho olufanelekileyo amaxesha amaninzi. Kwakhona, xa kuthelekiswa ne-GH4, le khamera inokubamba i-10-bit 4: 2: 2 i-footage ngaphakathi kwaye lo mgangatho wawufumaneka kuphela ngaphambili ngokongezwa kwerekhoda yangaphandle ngenxa yoko awudingi zixhobo zongezelelekileyo ukuze ufumane iziphumo ezintle.

Ubunzulu obuPhambili ukusuka kwiDefocus

Inkqubo ye-DFD yaziswa ngaphambili yiPanasonic kodwa nge-GH5 sinenguqulo yayo yamva nje. Le nkqubo isebenzisa izibini zemifanekiso kunye nolwazi olunzulu ekunikezelweni kweelensi ekugxilwe kuzo ukwenza imephu enzulu yendawo ejolise ekwenzeni inkqubo yokugxila ikhawuleze. Ngamandla okusombulula ngakumbi, i-GH5 inokuthi isampule imiboniso ngokuhamba rhoqo kwaye ke imephu enzulu inokuba nesisombululo esiphezulu esiya kuthi sikhokelele kugxilwe ngcono.

Ukutolikwa kwentshukumo kwindawo yesehlo ngoku kubonisa ialgorithm ehambele phambili kunye ne-GH5 kwaye oku kunciphisa umngcipheko wokuba ikhamera iphinde ichaphazeleke ngelixa isakha imephu enzulu. Izinketho zoqwalaselo lwe-AF ngoku zinokwahluka kakhulu kwaye oku kuyanceda ukuba usete ikhamera ukuba ikuqonde kakuhle ukuhamba kwesifundo kwaye ke uphendule ngokuchanekileyo kuyo.

Kusenziwa umfanekiso

Ezi njongo ziphambili zenzelwe ukuba iPanasonic Lumix DC-GH5 yenzelwe ukuthatha imifanekiso kunye nevidiyo. Njengoko inamandla okusombulula ngakumbi kunangaphambili, oku kuvumela indawo ebanzi yomfanekiso ukuba ithathelwe ingqalelo xa kubalwa amaxabiso ombala wepikseli nganye kwaye oku kubonelela ngesisombululo seJPEG esibuhlungu kumfanekiso obanjiweyo.

Amandla ongezelelweyo okuqhubekeka kukwathetha ukuba ukulola kuhambele phambili ngakumbi xa kuthelekiswa neemodeli zangaphambili kwaye ke ukudubula okugqithisileyo kuya kuncitshiswa ukuze ube nee-halos ezingaphantsi okanye imiphetho enokungafani okuphezulu okuya kunika umfanekiso ukuziva okungaqhelekanga.

Iimowudi zokudubula eziPhucukileyo zeVidiyo kunye neFoto ye6K

I-stills inezinto ezinje ngefoto ye-4K, iPost Focus kunye nokuGxila ekugxinineni okuthetha ukuba i-GH5 ibonelela ngoguqulelo oluphezulu lwazo kunye ne-pixel count sensor kungcono apha. Iprosesa inokongeza oko kubizwa yiPanasonic imowudi 'ye-6K Photo' efikelela kwi-30fps kwaye sikwanayo le foto ye-4K sele ikhankanyiwe kwizakhelo ezingama-60 ngomzuzwana. Imowudi inokubangela ngeendlela ezininzi ukuze ukhuphe umzuzu ofuna ukuwubamba ngokuchaneka okuninzi. Sibeke imo ye-6K kwizicatshulwa njengoko oko kungathethi ngqo ukuba imifanekiso iza kuvela kwindawo yesenzi esiziipikseli ezingama-6000 ngaphesheya. Ifota imifanekiso kwisisombululo esifana naleyo yevidiyo engama-6000 x 3000 kwaye yiyo loo nto ilahlekisa ukuyibiza ngokuba yi-6K.

Ngokubanzi le khamera iya kumangalisa ngokwenene kwizandla zobuchwephesha njengoko iza nezinto ezininzi ezinye iikhamera ezingayenzi kodwa kunokubonakala ngathi zininzi kakhulu kubaqalayo.
