MILC vs DSLR Lub Koob Yees Duab
DSLR koob yees duab thiab MIL koob yees duab yog ob hom koob yees duab ntsib hauv kev yees duab. Ob qho qauv no muaj lawv qhov zoo thiab qhov zoo. Kab lus no yuav sim daws cov teeb meem ntawm lawv cov qauv tsim, lawv qhov tsis zoo thiab qhov zoo, qhov zoo sib xws thiab thaum kawg qhov sib txawv ntawm DSLR koob yees duab thiab MIL koob yees duab.
DSLR koob yees duab
DSLR sawv cev rau lo lus digital tib lub lens reflex. Cov koob yees duab DSLR yog hom koob yees duab digital siab heev. Lub koob yees duab digital yog ib qho khoom siv, uas siv lub matrix ntawm lub teeb rhiab hluav taws xob cov khoom siv hluav taws xob raws li lub phaj sensor txhawm rau ntes cov duab. Sensor technologies, xws li CMOS (Complementary Metal Oxide Semiconductor) thiab CCD (Charged Coupled Devices), yog siv hauv DSLR koob yees duab. Cov ntaub ntawv no ces hloov mus rau hauv binary me ntsis qauv, uas yog khaws cia rau hauv lub cim xeeb ntawm lub koob yees duab. Cov duab khaws cia yog ob hom; ib qho yog qhov twg cov duab yog compressed ua ntej khaws cia. Cov hom ntawv xws li JPEG, GIF, thiab TIFF yog hom compressing zoo li no. Hom ntawv zoo li RAW sau cov duab yam tsis muaj kev hloov pauv; Yog li ntawd, zoo siab tau txais, tab sis qhov no ua rau tsawg dua cov duab ib daim npav nco. Nws siv lub lens cais thiab lub cev ob qho tib si uas kim tshaj li ib txwm taw tes thiab tua cov koob yees duab digital. Cov lo ntsiab muag no zoo heev thiab muaj lub lens loj heev qhib dua li cov koob yees duab ib txwm. Yog li ntawd, lub sharpness ntawm cov duab yog ho siab. Cov lo ntsiab muag thiab lub koob yees duab lub cev muaj cov ntawv qhia tag nrho thiab tsis siv neeg tswj cov duab, xws li cov nyiaj dawb mus rau cov ntsiab lus tsom.
MILC
MILC stands rau iav-tsawg interchangeable lens koob yees duab. MIL koob yees duab yog ib hom koob yees duab tshiab, uas ntog ntawm cov koob yees duab compact thiab DSLR koob yees duab. Lub TTL (los ntawm lub lens) tsom qhov system ntawm DSLR lub koob yees duab siv lub teeb nkag los ntawm lub lens kom pom cov duab. Cov txheej txheem no suav nrog daim iav, uas qhia txog lub teeb rau penta-prism qhov twg nws tau cuam tshuam rau qhov pom ntawm lub koob yees duab. Lub koob yees duab MIL tsis muaj daim iav zoo li lub koob yees duab DSLR. MIL koob yees duab yog tsim los kom muaj cov sensors loj hauv lub cev me. Lub sensor ntawm MIL lub koob yees duab yog yuav luag qhov loj ntawm lub koob yees duab DSLR. Txawm li cas los xij, TTL tsom qhov system raug tshem tawm nrog rau daim iav. Lub koob yees duab MIL tsis muaj TTL saib. MIL lub koob yees duab yuav zoo li lub koob yees duab digital compact nrog lub sensor loj thiab lub lens loj. Lub tswv yim ntawm MIL lub koob yees duab yog xa cov duab zoo ntawm DSLR lub koob yees duab hauv lub cev ntau dua. Qhov teeb meem tseem ceeb ntawm MIL lub koob yees duab tsim yog qhov tsis muaj TTL viewfinder. Qhov no kuj txo cov roj teeb lub neej txij li kev pom nyob ib txwm ua haujlwm ntawm MIL lub koob yees duab.
Qhov txawv ntawm MIL lub koob yees duab thiab DSLR lub koob yees duab yog dab tsi?
• DSLR lub koob yees duab muaj TTL saib thaum lub koob yees duab MIL tsuas muaj lub LCD saib.
• Lub kaw lus tsom ntawm MIL lub koob yees duab yog ua raws li kev pom qhov sib txawv; thaum lub teeb pom kev zoo ntawm DSLR koob yees duab yog ua raws li qhov tseeb dua thiab cov txheej txheem tshawb nrhiav qhov tseeb.
