Thenga amakhamera anama-megapixel kakhulu
Uma kuziwa ikhamera enkulu yokuxazulula, uzothola izithombe ezinhle kunazo zonke ngenxa yokuba nenzwa enkulu kunazo zonke, ama-megapixels amaningi, ama-lenses amahle kakhulu nezinsimbi eziphezulu kakhulu kunanoma iyiphi enye iklasi yekhamera. Lokhu akusho ukuthi ezinye amakhamera ngeke zinikeze imiphumela emihle yezithombe noma ukuthi ukuxazulula okukhulu kuqinisekisa imiphumela emihle. Ekugcineni, kunezici eziningana ezithinta ikhwalithi yesithombe ezifana nokukhanyisa, ukujula kwensimu, ukuvula nokugxila, futhi bonke bangadlala indima eyinhloko endleleni umthwebuli wezithombe angawuthatha ngayo isithombe nesithombe esihle kunazo zonke.
Uma ufuna ikhamera yokuxazulula eliphezulu, i-EOS 5DS R ye-Canon yi-crème de la crème, enikeza ama-megapixel angu-50.6 enhle wokuxazulula. Ungenzi iphutha ngakho, i-EOS inqume ukuba ibhuloho oyinhloko kanti ngenkathi inikeza ukuthuthwa kwevidiyo ka-1920 x 1080 30fps, le ikhamera ye-frame ephelele isho isithombe esisekhona. Umthamo wamanani ophezulu ungowomzimba kuphela, akukho lens ehlanganisiwe, kodwa i-Canon inikeza ukubulawa kwezingqimba ze-EF ezingasetshenziswa nge-EOS. Ama-lens eceleni, i-Canon yengeze isihlungi esiphansi sokusiza ukusizakala ngokugcwele ngenzwa ye-CMOS ye-50.6-megapixel ukuletha izithombe eziphakeme ngisho nokulungiswa.
Umzimba wekhamera ngokwawo ujwayelekile isitayela seCanon, omnyama futhi ugqoke ngaphandle kwezici ezikhethekile ezingasiza ukukwenza ukuthi zivelele esixukwini. Lokho kusho, linikeza i-ergonomic ehle kakhulu esandleni ngenkathi kudutshulwa kanye nomzimba ovalwe ngesimo sezulu ukuwuvikela ngokumelene nezakhi. Ama-pair e-LCD angama-3.2 ahleliwe anezibuko zokubuka eziphezulu ezingu-100 ezinikezayo .ukukhuliswa okungu -71x, okuyinto enhle kakhulu. Ukusiza ngokudubula, i-Canon yanezela i-autofocus engu-61 ekhomba ukuthi iphakathi kwezinga eliphezulu kakhulu kunoma iyiphi i-DSLR emakethe namuhla. Uma inani lemininingwane eliyinkimbinkimbi yilokho okudingekayo ukufotowa kwakho konke, yilo okumele lithenge.
Ngenkathi kungenzeka ukuthi ikhamera eyodwa kulolu hlu olungaphansi kwe $ 1,1, i-Olympus 'OM-D E-M5 Mark II inikeza inqubo ye-TruePic VII ye-megapixel engu-40 megapixel. Amaphesenti angaba ngu-40 amancane futhi alula ngaphezu kwe-DSLR yendabuko, i-Olympus ine-ergonomically body friendly-sealed body eshicilelwe phansi, engahambisani nokuthungatha futhi efakwe efrijini. Futhi nakuba kungabizi eshibhile ohlwini, akusizi izici. Inesistimu yokuqinisa ukuqina kwesithombe ezinhlanu ukuze kuncishiswe ukufiphaza okubangelwa ngesandla esicindezelayo sekhamera kanye namafreyimu angu-10 ngesigamu sokudubula okuphezulu kwesigamu. Njengamakhamera amaningi egcwele, i-Olympus ihlanganisa ividiyo, kodwa iya ngaphesheya komncintiswano wayo ophezulu kakhulu ngokunikeza ukuthuthwa kwevidiyo ephelele ye-HD80 ku-60, 30, 25, naku-24fps.
Enye indawo lapho i-Olympus iwa khona nesabelomali isigaba sempilo yebhethri. Kuzo izithombe ezingu-310, kufushane, kodwa ukubambisana kwekhwalithi yesithombe nemali yebhajethi kusho (ukuthengwa ngokwehlukana) ibhethri yesibili ayikho embuzweni. Ngaphandle kwebhethri, i-Olympus isiza ukubuka izithombe ezithunjiwe futhi iphinde isebenze imenyu ngokubukwa kwe-LCD emasentimitha amathathu ehlangothini futhi ijikeleze ama-270 degrees. Isibuko sokubukwa kwe-electronic esisebenzayo sinikeza ukulawula okuphelele ezingeni leso lokubamba usuku noma ubusuku obusuku noma ngabe ukhona ku-studio noma ezintabeni. Phonsa ku-WiFi ngokudlulisela izithombe kwi-smartphone noma kwikhompyutha futhi umphumela uyibhuloho elihle lokubhalwa kwesabelomali elenza ikhamera elihle kakhulu, ikakhulukazi uma ungena ekuthunjweni kwesithombe nesithombe.
Yakhiwe ngebhethri ye-EN-EL15 ekhokhelwa kabusha i-li-ion, i-Nikon D850 iyakuthatha ukuthatha izithombe ezingu-1,840 ngemali eyodwa (okungukuthi amahora angu-70 wevidiyo engu-4K.) Yingu-1 entsha Ukukhishwa kuma-Cameras e-DSLR e-Amazon, futhi Kuqinisekile ukuthi kuzokugcina ngempelasonto yonke ngaphandle kwesidingo sokushaja uma uhamba nawe eholidini.
I-Nikon D850 yenzelwe isikrini sokuthinta isikrini esiphezulu esithinta isikrini esiphezulu esingenayo isilawuli se-low-pass optical. Ikhamera ye-heavyweight isebenzisa ama-megapixel angu-45.7 wekhwalithi yokuxazulula ngokweqile kanye nobubanzi obunamandla bokubheka kude, ungalokothi uphuphuke kwikhwalithi. Iyakwazi ukuthatha amafremu ayisishiyagalolunye ngomzuzwana ngokuxazululwa okugcwele ngaphandle kokuncipha kwezinqumo zesithombe noma. Uzokwazi ukurekhoda amavidiyo we-4K Ultra HD, kanye nokuphela kwesikhathi esingu-8K usebenzisa i-timer ye-interval. Kukhona nokunyakaza okusheshayo kufinyelela kuma-FPS angu-120 ngokugcwele isinqumo se-1080p.
Uma kuziwa emiphumeleni yezithombe eziyingqayizivele, i-45.7-megapixel Nikon D850 DSLR inikeza ngendlela enkulu. Ngenhlanhla, le khhamera ingaphezu kwama-megapixels kuphela, nezinye izinkomba ezivelele ezihlanganisa uhlelo lwe-autofocus ye-153-iphuzu, ukurekhoda kwevidiyo ye-4K kanye nokuphelelwa kwesikhathi, ukuxhuma kwe-Bluetooth kanye ne-Wi-Fi, kanye nama-shot frames-per-second bulst shots. Ngaphandle kwesethi sayo sesici, umklamo ulinganisa amakhilogremu amabili futhi unesibopho esithintekayo esizizwa kahle nje esandleni.
Abasebenzisi be-Nikon besikhathi eside, ukusetha kokulawula kuzokwaziwa ngokushesha, nezinkinobho ezihlelwe ngendlela ejwayelekile ye-Nikon, nakuba uzothola ukudayela okuzinikezele ngakwesokunxele bese inkinobho ye-ISO ishintshwe inkinobho yemodi. I-3.2-intshi yokwehlisa i-LCD ihlukile kakhulu futhi inokusekelwa kwesikrini okuthinta ukuvumela imenyu elula futhi esheshayo.
Ngenkathi isibalo saso se-megapixel singase singaba phezulu njengabanye abalingani bayo, ikhamera ye-Pentax KP 24.32-megapixel DSLR inikeza inhlanganisela yokuma izithombe nokuvikelwa ezakhiweni. Ukuphefumula nokumelana namanzi, i-Pentax ingasingatha izimo ezimbi kakhulu kuze kube yizi-14 degrees Fahrenheit ngaphambi kokuhluleka ukusebenza. Umklamo wayo womzimba omncane usisiza ukuba usebenze kahle ngokuzithokozisa noma ngokuhamba ngezindlela.
Njengoba ikhamera yokuqala ye-APS-C ukuhlanganisa ukunciphisa ukunyakaza, i-Pentax inikeza inqubo emihlanu ye-axis ukusiza ukungalingani ikhamera ngokumelene nokuzamazama kwemvelo esandleni ukuze unikeze imiphumela evelele yezithombe ngomshini ngamunye we-shutter. Ukwengeza, i-KP iklanyelwe ukuzwela kwe-ISO engu-819 200, okwenza kube kuhle ukuthunjwa kwezithombe ebusuku. I-LCD ephikisayo isiza umthwebuli wezithombe ngezokudubula kokubili okuphezulu nokuphansi.
Ukufuna kweCanon ukulawula imakethe ye-frame egcwele kuqhubeka ne-EOS 5D Mark IV ne-30.4 megapixel ye-DIGIC CMOS inzwa. Isixazululo esikhulu seMarku IV sinikeza ukulinganisela okungcono kakhulu phakathi kokuxazululwa kanye nobubanzi obunamandla ngenkathi kugcinwa idumela leCanon ngokukhipha umbala ophezulu. Ukuze usize ngokubamba ukudubula okuphelele njalo, i-Canon ifaka uhlelo lokuzivocavoca lwe-autofocus esheshayo nenembile engu-61, kanye nama-7 ozimele ngesigamu esiphezulu sokudubula okuqhubekayo ukuze uqinisekise ukuthi uthatha izifundo ezihamba phambili ngokukhululeka. Kuyinto encane yokugcina eyenza uMark IV uphelele ukushada izithombe, imidwebo nemicimbi yezemidlalo.
I-Canon yenzelwe ukuthi uMark IV abe nobudisi futhi, ngenkathi i-ergonomically ekhululekile futhi elula kakhulu ikhamera yefreyimu egcwele ngama-1.8 amakhilogremu, ukwengezwa kokuvalwa kwesimo sezulu kwenza kube kuhambelana nezakhi. Ukwengeza, i-Canon yongeze isinqumo sevidiyo esingu-4K ngo-30 fps ngesimo esibonakalayo esilula kakhulu sokusebenzisa futhi indlela esheshayo yokubamba izithombe ezingu-8.8-megapixel ezifakiwe kusuka kuvidiyo yakho. Phonsa ku-ISO ububanzi kusuka ku-100-32000 nge-50-102400 ukwandiswa futhi kulula ukubona ukuthi kungani uMark IV abezithombe abadwebile ngokugcwele. Ukuqeda isici sici iskrini sokuthinta isikrini se-LCD esingaba ngu-3.2-intshi esikuvumela ukuthi udonsa amamenyu bese ukhetha okukhethwa kukho, futhi uswayipha ngokusebenzisa izithombe nokunyathelisa, okuzizwa kahle ekhaya ngenxa yezwe le-smartphone .
I-Pentax ka-645Z kungenzeka ukuthi ikhishwe ngoJuni 2014, kodwa ikhamera yesikhulumi se-CMOS engu-51.4-megapixel isengumnandi wezithombe. Ngokuphila kwebhethri okudlula izithombe ezingu-650 nokubukezwa kwezinkanyezi eziyisihlanu ku-Amazon, i-645Z yibufakazi bokuthi iminyaka akudingeki ukuthi igugile. Njengomkhamera wefomethi ephakathi, akukho mbuzo ukuthi ithegi yentengo izoba ephakeme kakhulu ngaphambi kokuba ungeneze ekuthengeni kwe-lens, ngakho akusiyona into eyenzelwe ukudubula. I-format ye-Medium exels ekukhuliseni izithombe ngaphandle kokulahlekelwa imininingwane futhi yenza kangcono kunekhamera ejwayelekile ye-DLSR.
Kukhona kancane ijika lokufunda nge-Pentax, kodwa uma uthola isethi sici sesekhamera, iphupho ligcwaliseka ngenxa ye-landscape shots. Kungase kube lula ukuhlanganisa i-Pentax njenge-DSLR enamandla kakhulu ngenzwa enkulu, kodwa ngo-3.42 amakhilogrethi uzokwazi uma ubambe iPentax. Kodwa naphezu kwesisindo saso esinamandla, senzelwe i-ergonomically ukuba ibili ikhululekile futhi ilungele isaziso somzuzwana. I-LCD ye-3.2-intshi yokuhlola i-LCD iphelele ukubuka kuqala izithombe ngemva kokubanjwa. Kunamaphoyinti angu-27 we-autofocus ukusiza ukulandelela isihloko ngokugxila kokulingana ngokulinganayo njengoba kunokwenzeka nge-viewfinder ekhanyayo.
Ekugcineni, i-Pentax yehla izinga eliphezulu lesithombe futhi kuyamangalisa. Izithombe zimibalabala futhi zigcwele ukuphila, ngebanga eliguquguqukayo (kuze kufike ku-ISO 204,800) elingafinyelelwa kumkhawulo. Ividiyo ye-HD ephelele ibanjwe kuze kube ngu-60fps iyaphawuleka futhi njengomuntu onamandla ongacabanga ngombhoshongo onjalo wokulungisa. Ngakho-ke uma ubheka ukubamba nokuphrinta ngemininingwane ephakeme, i-645Z ibiza igama lakho (nekhredithi).
Ikhamera ye-A7R II egcwele isilawuli esingenakulinganiswa inikeza ama-megapixel angu-42.3 amangqayizivele wokuxazululwa okubanjwe nenzwa enkulu kunazo zonke ngemuva kwezimakethe emakethe. Akukho mbuzo ukuthi i-Sony A7R II iyinkimbinkimbi yesimo sezulu, ikhamera ejabulisayo ye-ergonomically okungukuphela kwephutha langempela impilo ebhethri yalo emfushane (ingadubuza izithombe ezingu-340 ngaphambi kokulayishwa). Noma kunjalo ukusebenza okuhle kakhulu okukhanyayo nokusimama kwesithombe esizakhele kuyoba nonke ngaphandle kokungazinaki impilo emfushane yebhethri. Inzwa ye-CMOS ngokwayo inikeza ukulungiswa okunamandla nokusebenza komsindo, ngakho-ke izithombe namanje amavidiyo akuyona into emangalisa kakhulu. Ukwengeza, ama-399 on-sensor amaphuzu wokuthola ama-autofocus ahle kakhulu, angagxila amehlo enhloko ngenkathi ehamba.
Ukufakwa kwevidiyo engu-4K kuyaphawuleka njengoba kungavamile ukunikezwa ngekhamera ezigcwele ezixazululwe amakhamera lapho kugxile kakhulu kwimiphumela yesithombe namanje. Ukuthatha i-4K ngokugcwele noma ifomethi ye-Super 35 ngokusabalalisa okugcwele kwezilawuli zamandla inikeza imiphumela ephoqelelayo esiza ukwenza i-Sony ibe yinto ekhethiwe yokuthengwa kwamanani.
Kungakhathaliseki ukuthi yividiyo noma imifanekiso, ukuqiniswa kwesithombe esise-eksisini emihlanu emzimbeni kuneza isinxephezelo esinembile sokwehliswa ngokukhipha ikhamera ngokunyakaza ngokuzenzekelayo, ngokuzenzekelayo, ukugxuma, ukugoqa noma ukuqhuma ukuze kuqinisekiswe ukuthi isithombe nesithombe sezinzile. Futhi isibonisi se-Xtra Fine LCD esinesisentimitha ezintathu sinikezwe ngokuhambisana nesiboniso se-Tru-Finder electronic ukuqinisekisa ukuthi ubona konke kuhlaka ngaphambi kokukhipha.
