Adam Kos Ezikhangisweni ezimbalwa ezintsha, abakwaSamsung bahlekisa ngokuthi i-flagship yayo ye-Galaxy S21 Ultra izowadlula kanjani amandla okuthwebula we-iPhone 12 Pro Max. Okokuqala mayelana nokusondeza, bese kuba enanini lama-megapixel. Kodwa abahlakaniphile bayazi ukuthi ukuqhathanisa amandla okunjalo kungase kungafaneleki. AbakwaSamsung bavula zombili izikhangiso ngesiqubulo esithi "Ukuthuthukisa i-smartphone yakho akumele kube phansi." Eyokuqala inesihloko esithi Space Zoom futhi imayelana nokuthatha izithombe zenyanga. Yomibili le mishini lapha ithwebula inyanga isebumnyameni obuphelele, ne-iPhone 12 Pro Max ekwazi ukusondeza ku-12x, i-Samsung Galaxy S21 Ultra 100x. Umphumela uvuna ngokusobala imbangi ye-Apple, kepha…
Kuzo zombili izimo, vele, lokhu ukusondeza kwedijithali. I-Apple iPhone 12 Pro Max inikezela ngokusondeza okungu-2,5x, kuyilapho i-Samsung Galaxy S21 Ultra inikela nge-108x ngekhamera yayo engu-3MP, kodwa futhi inekhamera ye-periscope engu-10x. Noma yini ngemva kwalokho yenziwa kuphela ngokunqampuna isivuno esisikiwe esithombeni. Yomibili imiphumela izobe isilingana nemali endala. Noma ngabe yini oyithwebulayo, zama ukugwema ukusondeza kwedijithali ngangokunokwenzeka, njengoba lokhu kuzokwehlisa umphumela kuphela. Kungakhathaliseki ukuthi iyiphi i-smartphone oyisebenzisayo.

Hhayi u-108 Mpx njengo-108 Mpx
Isikhangiso sesibili sibe sesikhombisa isithombe se-hamburger. Ibizwa nje nge-108MP, ibhekisa ekuxazululweni kwekhamera eyinhloko ye-Galaxy S108 Ultra's 21MP, ukuyiqhathanisa ne-12MP ye-iPhone 12 Pro Max. Isikhangiso sisho ukuthi isithombe esithathwe ngamamegapixel amaningi sizokuvumela ukuthi ubone imininingwane ebukhali ngempela, kanti isithombe esithathwe nge-iPhone ngeke.
Kepha cabanga ngosayizi we-chip, ozohlinzeka ngenani elikhulu lamaphikseli njenge-Samsung. Njengomphumela, lokhu kusho ukuthi iphikseli eyodwa inosayizi ongu-0,8 µm. Endabeni ye-iPhone 12 Pro Max, i-Apple ihambe ngendlela yokugcina inani lamaphikseli, elizokhula nakakhulu nge-chip ngokwayo. Umphumela uyi-pixel engu-1,7 µm. Ngakho-ke usayizi wamaphikseli we-iPhone mkhulu ngokuphindwe kabili kunowakwaSamsung. Futhi lena indlela, hhayi ukuphishekela inombolo yama-megapixel.
Kodwa-ke, i-Samsung inikeza ubuchwepheshe be-pixel binning, i.e. ukuhlanganisa amaphikseli abe munye. Kalula nje, i-Samsung Galaxy S21 Ultra ihlanganisa amaphikseli angu-9 ibe yinye. Lokhu kuhlanganisa kwephikseli kuhlanganisa idatha esuka kumaphikseli amaningana amancane kunzwa yesithombe ibe yiphikseli eyodwa enkulu ebonakalayo. Inzuzo kufanele kube ukuzivumelanisa okukhulu kwenzwa yesithombe ezimeni ezahlukene. Lokhu kuwusizo ngempela ezimweni zokukhanya okuphansi lapho amaphikseli amakhulu engcono kakhulu ekugcineni umsindo wesithombe ungekho. Kodwa…

I-DXOMARK icacile
Yini enye okufanele ubhekisele kuyo, kunokuhlolwa okudumile (hhayi kuphela) kwezimfanelo zezithombe zomakhalekhukhwini DxOMark, ukuze "siqhume" ingxabano yethu. Ubani omunye onganikeza umbono ongachemile, ongeyena umlandeli wanoma yiluphi uhlobo lomkhiqizo futhi avivinye umshini ngamunye ngokuya ngemininingwane ecacile. Imodeli ye-iPhone 12 Pro Max ithatha indawo yesi-130 kuyo ngamaphuzu ayi-7 (imodeli engenayo i-Max moniker ingemuva kwayo). I-Samsung Galaxy S21 Ultra 5G ene-Snapdragon chip isendaweni ye-123 eyabelwe ngamaphoyinti angu-14, leyo ene-Exynos chip enamaphuzu angu-121 ngisho nasendaweni ye-18 okwabelwana ngayo.
Kungaba njalo okuthakaselayo
Iqiniso lokuthi alitholwanga yi-iPhone 11 Pro Max kuphela, kodwa nayimodeli yangaphambilini evela ku-Samsung Galaxy S20 Ultra 5G yakwa-Samsung, lifakazela neqiniso lokuthi ubusha be-Samsung abuzange buphumelele kakhulu mayelana nokuthatha izithombe. Ngakho-ke kuyatuseka ukuthi ungagxumi ku-bandwagon yanoma ngubani ozama ukuhlasela ngamasu okuthengisa ahlaba umxhwele. Asisoli i-Samsung ngaleli qhinga. Izikhangiso zihloselwe imakethe yaseMelika kuphela, ngoba ngeke ziphumelele emakethe yaseYurophu ngenxa yemithetho yendawo.
Ngasijabulela kakhulu lesi sihloko. Ngincoma ukuthi ufunde okuthile mayelana nesilinganiso se-DXO. Okungagxili nakancane kokuningi kwalokho okwenziwa ucingo, kodwa kuphela emabhodleleni ayo ethwebula kuwo izithombe. Kufanele ngabe ngasho ukuthi akuphumelelanga ekuhlolweni kokusondeza okungu-10x ngoba ngihlola i-8x. Nginawo womabili amafoni. Ngithole i-S21 ultra ne-iPhone njengesipho futhi ngiyayithengisa. Kodwa ngenxa yelukuluku ngabaqhathanisa. Ikakhulukazi lawo makhamera. Ukungena kuFerrari nokushayela uzungeza idolobhana ngeke kube mnandi kakhulu. :) ngakho indlela yokuhlola ye-DXO ilahlekisa kakhulu. Iminyaka engu-2, ngiqala ukuhlola bese ngihlola.
