Key Takeaways
- Canon tau tshaj tawm lub koob yees duab yuav luag 70 xyoo tsim.
- SLRs, thiab tom qab ntawd DSLRs, ua ke qhov hloov pauv loj nrog cov duab zoo txaus.
-
Cov koob yees duab tsis pom kev yuav zaum hloov SLRs hauv ob peb xyoos ntxiv.
Lub DSLR yog lub koob yees duab ua tau zoo tshaj plaws thiab ua haujlwm ntev hauv keeb kwm, tab sis nws txoj kev khiav yuav xaus.
Tus qauv tsim yooj yim ntawm DSLR hnub rov qab mus rau xyoo 1940s, thiab nws tau siv sijhawm ntev dua li lwm lub koob yees duab tsim, ua tsaug rau nws qhov tshwj xeeb ua ke ntawm kev hloov pauv huab cua, me me-ish loj, thiab kav ntev. SLRs tau khob ib ncig ntawm lub hnab canvas ntawm cov kws yees duab ua tsov rog, tua kab tshoob, zam, portraits, kis las, thiab lwm yam. Thiab Hasselblad qhov nruab nrab hom ntawv txawm mus rau lub hli.
Tab sis nws lub sijhawm dhau lawm; Canon nyuam qhuav tshaj tawm tias nws yuav tsim tsis muaj DSLRs tshiab. Nws EOS-1D X Mark III yuav yog nws tus qauv pro kawg; lub neej tom ntej yog mirrorless.
"Hnub no, lub koob yees duab tsis muaj iav tau dhau los ntawm cov yam ntxwv thiab qhov zoo ntawm lub sensor. Qhov no, ua ke nrog lawv cov me me, lub cev hnyav thiab cov kwj ntawm cov lo ntsiab muag tshiab ua rau iav tsis muaj, tag nrho cov teeb meem no tau hloov qhov sib npaug hauv nyiam ntawm lub koob yees duab tsis muaj iav, "tus kws yees duab thiab tus kws yees duab tus kws qhia Mario Pérez hais rau Lifewire ntawm email.
Tus Reflex
Ua ntej SLR, lossis Tib Lub Lens Reflex, cov koob yees duab feem ntau loj thiab / lossis txwv. Lub gimmick yeej yog daim iav hauv lub cev, uas cuam tshuam cov duab los ntawm lub lens mus rau hauv qhov pom. Qhov no cia tus kws yees duab pom lub thav duab uas yuav tshwm sim ntawm zaj duab xis lossis sensor. Daim iav tig mus (qhov "reflex") tawm ntawm txoj kev ua ntej koj thaij duab.
Qhov no txhais tau tias tus kws yees duab tuaj yeem siv lub lens ultra-telephoto thiab saib los ntawm nws kom pom qhov chaw nyob deb ze ze. Leica cov koob yees duab rangefinder tsis muaj txiaj ntsig nrog telephoto lossis ultra-wide lo ntsiab muag vim tias koj ib txwm saib los ntawm ib qho kev sib cais, tsau saib.
Qhov no txhais tau tias SLR tuaj yeem siv los ua txhua yam kev yees duab. Tsuas yog vim li cas thiaj xaiv ib lub koob yees duab sib txawv yog siv lub thav duab loj dua (kom daws tau qhov zoo dua) lossis lub koob yees duab me dua.
Lub SLR tau hloov pauv mus rau digital los ntawm kev sib pauv cov yeeb yaj kiab rau lub sensor, tab sis tam sim no mirrorless thev naus laus zis tau ua rau daim iav reflex tej yam yees siv dhau lawm.
Mirrorless
Lub koob yees duab tsis muaj iav siv lub koob yees duab nyob ntawm lub koob yees duab sensor thiab xa mus rau qhov screen hauv qhov pom (lossis nyob tom qab lub koob yees duab). Qhov no txhais tau tias koj tsis xav tau daim iav ntxiv lawm. Thiab vim tias daim iav xav tau ntau qhov chaw, lub koob yees duab mirrorless muaj ntau dua. Qhov no kuj txhais tau tias me me lo ntsiab muag, tab sis muaj lwm yam zoo.
Hnub no, lub koob yees duab mirrorless tau dhau los ntawm cov yam ntxwv thiab qhov ntsuas qhov zoo.
Piv txwv li, DSLR qhia qhov tseeb thav duab, tab sis nws tsis tuaj yeem pom cov duab tiav lawm. Rau qhov ntawd, koj yuav tsum coj koj lub qhov muag tawm ntawm qhov pom qhov muag thiab xyuas qhov screen.
Lub koob yees duab tsis muaj iav qhia koj cov duab meej koj yuav ntes ua ntej koj ntes nws. Koj tuaj yeem saib ua ntej kom pom tseeb, raug, txawm tias pom cov duab dub thiab dawb. Niaj hnub no, sensors thiab tshuaj ntsuam tech yog ceev thiab siab-res txaus los sib tw nrog qhov muag pom ntawm SLR, nrog rau tag nrho cov txiaj ntsig ntxiv. Thiab nws zoo nkaus li kev ua lag luam qhia txog qhov no. Peb feem ntau siv peb lub xov tooj los thaij duab. Tab sis cov kws tshaj lij tau hloov mus rau cov koob yees duab me me, nrawm dua, siv tau yooj yim dua.
Niche Formats
Lub SLR tej zaum yuav yog lub koob yees duab hloov tau yooj yim tshaj plaws hauv keeb kwm txog tam sim no, tab sis qhov ntawd tsis tau txhais hais tias nws yog qhov zoo tshaj plaws ntawm txhua yam nws tau ua.
"Lub [Leica-style] rangefinder yog ib qho kev xaiv nrov ntev dhau los, feem ntau rau nws cov compactness," tus kws yees duab kws Rafael Larin hais rau Lifewire ntawm email.
Qhov tseeb, Leica ua rau tib lub koob yees duab ua yeeb yaj kiab nkaus xwb tseem muaj hnub no, thiab cov no yog rangefinders. Kuj tseem muaj lwm hom koob yees duab niche, tab sis lawv feem ntau yog txhais los ntawm qhov loj ntawm lawv cov sensor es tsis yog qhov txawv ntawm lub koob yees duab tsim.
"Lub koob yees duab hom nruab nrab txuas ntxiv yog ib qho kev xaiv rau cov neeg nrhiav cov duab zoo dua li DSLR tuaj yeem tsim," hais Larin.
Ua tsaug rau physics, cov sensors loj tsis yog hais txog kev daws teeb meem ntau dua. Lawv kuj muab qhov tob tob-ntawm-teb. Ntawd yog, lawv tuaj yeem plam tom qab ntau dua li cov koob yees duab nrog cov sensors me. Tab sis txawm tias qhov ntawd tsis muaj teeb meem rau mirrorless-lawv tsuas yog xav tau cov sensors loj.
Tshwj tsis yog lub koob yees duab xov tooj tau txais txiaj ntsig zoo dua thiab pib muaj kev sib raug zoo nrog cov lo ntsiab muag ntxiv lossis studio teeb pom kev zoo, nws yog qhov kev nyab xeeb ncaj ncees uas cov koob yees duab tsis muaj iav yuav ua haujlwm ntawm SLRs rau yav tom ntej.
