Key Takeaways
- Tshem tawm cov xim lim dej hla lub koob yees duab sensor txhawb nws qhov kev nkag siab thiab ntse.
- Digital B&W kws yees duab txiav txim siab $6,000 los ua tus txheeb ze sib tham.
- Txoj kev pheej yig tshaj kom tau lub koob yees duab dub thiab dawb yog los tua zaj duab xis.
Leica tus tshiab Q2 Monochrom yog 46.7 Megapixel tsiaj nyaum ntawm lub koob yees duab. Nws raug nqi $ 6,000, muaj lub lens ruaj, thiab nws tsuas yog siv cov duab dub thiab dawb xwb. Puas muaj leej twg xav yuav lub koob yees duab no?
Lub Monochrom yog qhov txawv ntawm Q2 li niaj zaus. Nws zoo nkauj npaum li cas tib lub koob yees duab, tsuas yog $ 1,000 ntxiv thiab nrog cov xim tshem tawm. Tab sis yog tias koj tua feem ntau B&W cov duab, ces nws zoo li koj twb tau ua haujlwm li cas los them rau qhov no. Thiab piv rau lwm yam Monochrom Leicas, qhov no yog pheej yig.
"Nws yog qhov tseeb ntawm 'cov cuab yeej tsim nyog rau txoj haujlwm,'" B&W kws yees duab Gregory Simpson hais rau Lifewire ntawm email. "Yog tias koj 'txoj haujlwm' yog los thaij duab B&W, ces txoj haujlwm ntawd tau ua tiav nrog lub koob yees duab B&W. Kuv paub tias qhov no yuav tsis yog rau txhua tus. Yog tias koj tsuas yog dabble hauv B&W, lossis siv nws ua ' effect' kom txuag tau ib daim duab uas tsis "ua haujlwm" xim, tom qab ntawd lub sensor monochromatic tsis ua rau muaj kev nkag siab zoo."
Lub koob yees duab xim ua haujlwm li cas
Lub Q2 Monochrom muaj lub ntsej muag puv (qhov loj ntawm lub thav duab ntawm 35mm zaj duab xis) sensor, tsau 28mm ƒ1.7 lens, thiab cov txheej txheem tsawg kawg nkaus. Lub viewfinder muaj OLED npo sab hauv, thiab lub rear 3-nti saib yog kov rhiab heev. Nws tseem tuaj yeem tua 4K video, tab sis qhov ntawd yuav, tau kawg, yog xim dub thiab dawb.
Dab tsi, yog li ntawd, yog lub ntsiab lus ntawm B&W-tsuas yog lub koob yees duab? Ua ntej, peb yuav tsum paub tias lub koob yees duab xim ua haujlwm li cas. Txhua lub koob yees duab sensors yog xim dub thiab dawb, thaum lub pixels rhiab rau lub teeb ntawm txhua xim. Ib daim phiaj ntawm cov lim liab, ntsuab, thiab xiav yog muab tso rau ntawm cov pixels; lub lim ntsuab cia los ntawm tsuas yog lub teeb ntsuab, lub lim liab cia rau hauv lub teeb liab, thiab lwm yam. Nws zoo li qhov no:
Qhov kev teeb tsa no muaj ob qhov txiaj ntsig. Ib qho yog tias cov lim lawv tus kheej thaiv qee lub teeb. Cov lim ntsuab txiav tawm xiav thiab liab, piv txwv li. Lwm qhov yog tias cov RGB pixels yuav tsum tau ua tiav kom txog rau ntawm daim duab kawg.
Yog tias koj tshem tawm cov xim lim dej, koj tso lub teeb ntau dua, thiab txhua lub pixel tsuas yog sau cov teeb pom kev ntawm nws. Qhov tshwm sim yog lub sensor rhiab dua, thiab kev daws teeb meem zoo dua.
"Kev khiav ib daim duab los ntawm kev ncaj ncees-nyem, txoj kev algorithmic demosaicing nyuaj tsuas yog tom qab ntawd muab pov tseg qhov kawg ntawm cov txheej txheem (xim) ua rau tsis muaj txiaj ntsig rau kuv kev yees duab," hais Simpson.
Yog tias koj 'txoj haujlwm' yog los thaij duab B&W, ces txoj haujlwm ntawd zoo dua nrog lub koob yees duab B&W.
Leica's Q2 Monochrom sensor, tom qab ntawd, xa tag nrho 46.7 ntawm nws cov megapixels li cov pixels dub thiab dawb, txhais tau tias nws muaj kev nkag siab ntau dua ntawm lub teeb qis, muaj suab nrov tsawg, thiab cov duab yog absurdly ntse thiab ntxaws. Qhov ntsuas ISO ntawm lub koob yees duab no yog qhov tsis txaus ntseeg 100, 000, thiab txawm tias thaum lub suab nrov digital pib nkag mus, nws yog lub suab nrov zoo nkauj, tsis yog lub suab nrov nrov uas ua rau qee cov duab digital tsis zoo saib tsis zoo.
Meanwhile, qhov kev ntxhib los mos ntawm cov duab, thiab cov gradations du ntawm lub suab tsuas yog ua tsis tau thaum koj hloov cov duab xim rau mono.
kab hauv qab
Qhov laj thawj tseem ceeb los yuav lub koob yees duab Leica, sib nrug ntawm lawv lub neej ntev, yog rau lo ntsiab muag. Leica cov lo ntsiab muag yog deservedly legendary. Qhov no zoo li tsis muaj qhov tshwj xeeb, raws li kev sim thaum ntxov. Qhov tsuas yog ntes yog koj tsis tuaj yeem hloov lub lo ntsiab muag. Txawm li cas los xij, qhov kev daws teeb meem vwm ntawm lub sensor txhais tau tias koj tuaj yeem zoo siab "zoom hauv" los ntawm cropping daim duab. Lub koob yees duab yuav ua qhov digital zoom rau koj, nrog rau kev teeb tsa rau 35mm, 50mm, thiab 75mm, nrog rau qhov loj me 28mm.
Tus nqi
$5,995 yog kim rau peb feem coob. Tab sis nyob rau hauv lub ntiaj teb no ntawm Leica B&W koob yees duab, nws yog pheej yig.
"Thiab, txawm hais tias kuv tsis tuaj yeem them tus kheej Q2M, kuv xav tias nws yog tus nqi txaus nyiam rau qhov koj tau txais," Simpson hais. "Tom qab tag nrho, nws tsawg dua ib nrab ntawm tus nqi ntawm M10M + 28mm Summicron f/2 lens."
Rau qhov kev xav, Leica M10 Monochrom raug nqi $ 8, 295 rau lub cev, thaum lub lens yog $ 4, 895. Muab piv rau qhov ntawd, Q2 zoo li kev sib tham. Koj txawm tau txais autofocus.
Tab sis kom meej qhov no tsuas yog lub koob yees duab rau B&W tus kws yees duab loj tshaj plaws. Thiab txawm li ntawd los, muaj lwm txoj kev xaiv.
Nws yog qhov tseeb ntawm 'cov cuab yeej tsim nyog rau txoj haujlwm.'
Vim li cas ho tsis ua movie?
Rau ob peb puas nyiaj, koj tuaj yeem nqa lub koob yees duab qub thiab lub lens, thiab tua B&W zaj duab xis. Koj yuav tsis tau txais qhov kev daws teeb meem vwm ntawm Leica digital no, thiab zaj duab xis yog qhov yooj yim dua, tab sis $ 6k yuav ntau zaj duab xis.
Zaj duab xis tau pom qhov rov tshwm sim dua, thiab txawm tias M10 Monochrom tsis tuaj yeem rov ua dua lub suab ntawm Tri-X zaj duab xis. Koj tuaj yeem sib cav tias kev tsim kho hauv tsev thiab luam theej duab koj tus kheej cov duab yeeb yaj kiab yog kev cog lus loj. Kuv xav hais tias, rau tus kws yees duab pib xyaum ua yam tsawg kawg, nws yog qhov kev cog lus me me dua li tso rau rau tus loj ntawm lub koob yees duab uas yuav tawg lossis siv tsis tau hauv tsib xyoos.
