Amakhamera we-Canon Full-frame Full for Professionals

Sike safaka i-EOS R5 phambilini futhi siyazi ukuthi ifanelwe okungaphezulu kwalokho. Uma ucela isizathu esisodwa esithile selungelo laso, sizokunikeza ezimbili noma ngaphezulu.

Okokuqala inzwa ye-CMOS ephelele engama-36 x 24 mm 45 MP futhi iyikhamera yokuqala ye-EOS ukuba ne-5-axis sensor-shift image stabilization, isenze isithandwa sangempela phakathi kwamakhamera weCanon. Ngezimpawu ezichaziwe, uthola imininingwane engcono kakhulu kuma-stills angancintisana neminye imisebenzi ephezulu engenazibuko ne-DSLR.

NgokukaSolidSmack Photography Editor u-Evangeline Summers, ungathola futhi i-35 MP Frame Grabs ezithombeni zayo ze-8K ezijabulisa kakhulu. Okungcono nakakhulu, uma uCanon ethi '35 MP' ikhwalithi, empeleni isho 35 MP. Ukubamba kuza nemininingwane ebabazekayo futhi uthola cishe ama-elementi afanayo ozothola emifanekisweni emile yangempela.

Ngakolunye uhlangothi, i-Summers ithe imodi ne-buffer ye-EOS R5 izokumangaza.

“I-EOS R5 ingaletha izibhamu eziqhume kuze kufike ku-12fps nge-shutter mechanical kanye ne-20fps nge-shutter kagesi. Lokhu kungaphezu kokwanele futhi into enhle nge-R5 ukuthi ijule kangakanani ibhafa yayo. Inezikhala ezimbili zamakhadi futhi kuya ngokuthi usebenzisa ini, ungathola i-max buffer enezithombe ezingama-180 RAW ezine-slot yeCFexpress yekhadi noma izithombe ezingama-87 ze-RAW ezine-slot yekhadi le-UHS-II le-SD. ”

Futhi njengoba sisengxoxweni ngamavidiyo, i-R5 nayo ingahambisa amavidiyo angama-8K ku-30p. Kodwa-ke, kukhona i-caveat lapha okushisa kakhulu phakathi kwamakhamera anjalo lapho udubula noma yini engaphezulu kwevidiyo ejwayelekile ye-4K 30p. Noma kunjalo, ngeziqeshana ezimfushane kakhulu, sisabheka isici se-8K njengesengezo esihle.

Ngakolunye uhlangothi, i-R5 izishaya isifuba nge-Dual Pixel CMOS AF II okungenye yeCanon eziqhenya ngayo manje ngohlelo lwayo lwe-AF. Ihlanganisa izithombe ezinganyakazi ezinamaphoyinti angu-5,940 AF namavidiyo anamaphuzu angu-4,500. Ngokusho kwe-Summers, ungajabulela lobu buchwepheshe nganoma yisiphi isilinganiso nokulungiswa kozimele, okumangazayo ngempela uma kuqhathaniswa namanye amamodeli amakhamera anezici namakhono we-AF alinganiselwe. Okungcono nakakhulu, izuze isistimu ye-Deep Learning AF ye-1D X.

“Ukuphumelela ngendlela egculisayo ukuthi ukuthola izifundo zakho, kungakhathalekile ukuthi zinyakaza kanjani, kuzokulethela izinyembezi. Indlela i-AF evala ngayo futhi ihlale nesihloko imangalisa ngempela; kungaba ubuso, ikhanda, noma ukulandelela iso. Uma ikhamera isibonile isihloko somuntu, kugxilwa lapho kufanele kube khona ngisho noma umakoti egqoke iveyili noma avale ubuso bakhe ngesixha noma izandla nanoma yini,” kusho uSummers.

Kodwa-ke, lokho kuyinto engaheha abathwebuli bezithombe basemgwaqweni. Ngakho-ke, yini engaletha u-R5 etafuleni kubathwebuli bezilwane zasendle? Lolu hlelo oluhlakaniphile luphinde lusekele i-Animal AF okuyinto i-1D X engayinikezi nakancane. Hhayi lokho nje… isebenza ngempela nasezifundweni zezilwane ezihambayo! UCanon wenze umsebenzi omuhle kakhulu ekudaleni i-algorithm engcono kakhulu ekwazi ukubona amehlo ezilwane ngokushesha nje lapho ukhomba ikhamera yakho. Ngezilungiselelo ezilula ezifanele, ikhamera ingakwazi ukulandelela ngisho nezinyamazane zasendle nezinamahloni kakhulu ngaphakathi kohlaka. Sesikushilo lokho, ukuthola imidwebo egcwele imininingwane kungenzeka ngaso sonke isikhathi.

Yize i-EOS-1D X Mark III iyimodeli yohlaka olugcwele, akuyona ikhamera yakho enokulungiswa okuphezulu kokunyakazisa ngenxa yokulungiswa kwayo okungu-20.1 MP. Futhi, iyimodeli enhle kakhulu engenqaba abantu abathile, ingasaphathwa eyokuthi futhi ine-LCD yesikrini esithintwayo esingaguquki. Nokho, kwezinye izigaba, kungase kube kubi kakhulu.

Iqala ngamakhono ayo evidiyo akuvumela ukuthi ushuthe hhayi amavidiyo agcwele uhlaka lwe-4K/60p kodwa namavidiyo angu-5.5K RAW! Ngokuqondene nejubane, ungumpetha weqiniso. Ayizi nje ne-Dual Pixel CMOS AF kodwa futhi izishaya isifuba ngendlela entsha yeCanon ye-AF ngendlela ye-EOS iTR AFX. Ngenxa yephrosesa yayo eyengeziwe ye-Digic X, le nto ebizwa ngokuthi 'I-Deep Learning AF' ingalandelela inhloko yesihloko uma isithwetshulwe uhlelo.

“Ukuze ube nombono ongcono walesi simiso, ake ucabange ngomuntu ogibele isithuthuthu ngesivinini esikhulu. Okugqamile nge-iTR AFX ukuthi i-algorithm yayo isethwe ukuthi igxile ekhanda lezifundo noma ngabe zigqokile izigqoko noma cha. Lokhu kubikezela isenzo sesihloko esenza kube lula ukuthi uhlelo lwe-AF lulandele isihloko ngaphandle kwesivinini. Uzojabulela izinzuzo zayo ezigcwele ngenketho ye-Live View lapho iphrosesa ye-Digic X isebenzisa umlingo wayo isebenzisa amaphuzu angu-3,869 e-Dual Pixel CMOS AF kanye ne-AF yokubona iso,” kusho u-Summers.

Ngisho ne-OVF AF yayo ingaba namandla. Ngamaphuzu we-AF angu-191 (angu-155 awo ewuhlobo oluhlukile), ukulandelela izifundo kungase kungabi namandla. Kukhona ngisho ne-AF yokubona ubuso ukuze ikusize ngenkathi i-Live View ithembisa ukubona iso eligcwele i-AF.

Ngakolunye uhlangothi, nakuba kuyiqiniso ukuthi ukulungiswa kwayo kwe-20 MP yezithombe ezimile kungase kube kancane, ijubane layo alinakuhlulwa uma kuziwa ekuzidubuleni. Ngenxa yokuqhuma kwayo okukhulu kwe-20fps, ayikwazi ukushiya umzuzu nje ingabanjwanga. Okuzokwenza uthande lo mfana omubi nakakhulu umthamo wakhe we-buffer owephula irekhodi ngokusebenzisa amakhadi amabili e-CFexpress akwazi ukuhlinzeka ngamafayela afinyelela ku-1,000 RAW kanye ne-JPEG! Ungagcina i-shutter icindezelwe isikhathi esingaphezu komzuzu futhi isazoqhubeka nokudubula!

ICanon EOS 5D Mark IV ayinaso isilondolozi esifiselekayo se-EOS-1D X Mark III. Inikeza kuphela isilinganiso sokuqhuma esingu-7fps kanye nomthamo webhafa we-21 RAW. Noma kunjalo, ingafinyelela ezingeni elijabulisayo lemininingwane emisebenzini yayo elenza ihluke kweminye.

“I-5D Mark IV inxephezela ngokuya ngezingxenye ezifaka isandla emininingwaneni yezithombe zayo. Okokuqala kuzo inzwa yohlaka olugcwele engu-30.4 MP eletha imininingwane engenakuqhathaniswa, ukuchayeka, ukugcwaliswa kwesikhala, kanye nekhwalithi yombala iyonke. Ngisho nasezimeni zokukhanya okuphansi kanye nezilungiselelo eziphezulu ze-ISO, inani lomsindo elikhona licishe lingabonakali,” kusho u-Summers.

Ngaphandle kokukhishwa kwayo kombala okumsulwa, ububanzi bayo obuguquguqukayo buzokunikeza uhlobo olungcono kakhulu lwenkululeko ekuvuseleleni imininingwane. Ngakho konke lokhu, ukuguqula isibhamu sibe ukuphrinta okukhulu ngeke kube ukukhathazeka ku-EOS 5D Mark IV. Ingase futhi inikeze ukusebenza okuhloniphekile ngokunemba kwezithombe ezinganyakazi zokudubula.

“Ngisho noma inikeza izinga lokuqhuma kwe-7fps, i-5D Mark IV ngeke yehluleke ukuthwebula izifundo ngokunemba okukhulu. Ngamaphoyinti angu-61 e-AF kanye ne-Dual Pixel AF, cishe akukholakali ukuthi ingathola kanjani isithombe sesihloko esihamba ngokushesha ngaphandle kokufiphala okuningi. Ngisho noma kusetshenziswa ukunqampuna ngokweqile, usengakwazi ukuthola imininingwane ehloniphekile efakazela ukuthi inamandla kangakanani inzwa yayo yohlaka olugcwele,” kwengeza u-Summers.

Isebenzisa amaphuzu angu-61 AF kanye nama-cross-type angu-5 ahlanganisiwe emaphuzwini ayo asevele ahlaba umxhwele angu-41 ngaphansi kwe-f/2.8 aperture. Lokhu kwenza i-AF isebenze ngempela ngisho nasezimweni ezimbi kakhulu zokukhanya okuphansi. Ngalokhu, ukugxila kuhlala kuthembekile futhi kungaguquki.

Ukukhishwa kwe-EOS R5 ne-R6 kwamenyezelwa ngasikhathi sinye (Julayi 2020). Lesi sakamuva sithembisa isethi engcono yezici ezizozuzisa umphakathi jikelele wabathwebuli bezithombe kodwa lokho akwenzi u-R6 noma yini engathandeki. Iwubuhle ngendlela yayo.

“I-R6 iphuma nenzwa engu-20.1 MP enohlaka olugcwele lwe-CMOS ekhombisa ukuthi mkhulu kangakanani umehluko wayo ne-R5,” kusho u-Summers. “Lokhu kusho ukuncishiswa kwezithombe zakho ezimile kodwa lokhu kuyivumela ukuthi ibe namandla afanayo no-R5 nama-fps angu-12 we-shutter engumshini kanye no-20fps we-electronic shutter.”

Ngakolunye uhlangothi, i-R6 inamanye amaphuzu amaningi amahle ongawanikeza okuhlanganisa i-ISO ephakeme efinyelela ku-ISO 102,400, amaphuzu okugxilwe kuwo kakhulu (6,072 Dual Pixel CMOS AF II), nempilo yebhethri engcono (ingadubula amashothi angama-40 ngaphezu R5), ukubala nje abambalwa.

Ngenxa ye-AF efanayo ephromotha i-Canon's Deep Learning AF kanye nenani eliphakeme lamaphoyinti e-AF, uhlelo lwayo lwe-autofocus lungasebenza ngendlela efanayo naleyo onayo ngama-R5. Iphinde iza ne-Animal AF, okuyivumela ukuthi ibe yinhle kakhulu iyunithi yekhamera yezilwane zasendle kanjalo.

Futhi nakuba ingakwazi ukuthwebula amavidiyo angu-8K, izici zayo zevidiyo zisahlangabezana nezindinganiso ngokuletha okuqoshiwe okungu-8 no-10-bit 4K UHD kufika ku-60fps. Futhi unenketho ye-1080p kufika ku-120fps u-R5 angeke akwazi ukukunikeza. Into enhle ngayo ukuthi izici zayo zokulandelela i-AF zingajatshulelwa kunoma yikuphi ukulungiswa kwevidiyo yayo kanye namazinga ozimele, okwenza kube ikhamera yevidiyo enamandla kakhulu, futhi.

Ngokujabulisayo, naphezu komehluko osobala phakathi kuka-R5 no-R6, isafika nohlelo lweCanon lokuqiniswa kwesithombe esingaphakathi kwe-5-axis sonke esasilulindile kumakhamera ayo. Kuya ngokuncika okusetshenziswayo, ukuzinza kungakhuphukela ezitobhini eziyi-8 njengaku-R5.

Ukukhululwa kwe-EOS 6D yasekuqaleni kwathatha iminyaka futhi manje njengoba sine-6D Mark II, kufanele sivume ukuthi siphazanyiswe umkhawulo wayo. Isibonelo, ayikwazi ukudubula nge-4K. Noma kunjalo, sisayincoma njengenye ye ama-Canon DSLR amahle kakhulu. Yebo, akhona amanye amamodeli angakwazi ukuyihlula kodwa ikhamera enohlaka olugcwele eza ngentengo engabizi kakhulu. Futhi lokho, sicabanga, kwanele ukuthethelela indawo yayo kulolu hlu. Phela, ithola ukuthuthuka okuningi okuyibeka ihluke ku-6D.

"Uma ungaqhathanisa lezi ezimbili, kuzoba nezizathu eziningi zokukhetha uMark II kunowandulelayo," kusho uSummers. “Ezinye zazo ukutholakala kwesikrini esithintwayo esichaza ngokugcwele, ukuqoshwa kwe-Timelapse, ukuzinza kwevidiyo yedijithali, uxhumano lwe-NFC ne-Bluetooth, umsebenzi wekhamera yewebhu, ukusekelwa kwekhadi le-UHS, nekhono lokungacwayizi.”
