Hloov cov feem ntau ntawm cov lwm cov tsis yog kuj ua los ntawm tsuas yog nias, nrog rau ISO chaw, dawb tshuav nyiaj li cas, kev hloov lub metering, raug them nyiaj, qhov chaw kawm Drive hom thiab pib kom pom tseeb (sab saum toj vaj huam sib luag). Txawm lub flash raug nyiaj yog kev mus rau hauv nws cov khawm mus rau sab laug ntawm lub lens mount. Tag nrho cov tseem ceeb functions, xav tau kev pab nws tus kheej shortcut daws yog qhov twg lawv yuav muab tau yooj yim pom.

Qhov chaw ntawm lub hwj chim hloov ib ncig ntawm lub shutter tso khawm yog yeej ib txwm preferable, vim hais tias koj muaj peev xwm tig rau cov koob yees duab, yeej tsis noj nws ob lub qhov muag los ntawm cov viewfinder.

Raws li nrog rau lwm yam tsheb ntawm no chaw tsim tshuaj paus, lub shutter suab yog kuj tsis tshua muaj.

Raws li lub tuam txhab, lub koob yees duab "Nikon D-90" yam ntxwv ceev nyob rau hauv tej rooj plaub yog ntau tshaj cov kev ceev ntawm nws precursor, xws li lub sij hawm pib (0.15 tiv tiag 0,18 mus D80), lub rooj vag ncua pickup (nrog 0,065 vs. 0 , 08), thiab lub sij hawm viewfinder blackout, uas poob mus rau 120 ms nrog 150.

Sensors AF steel SRS- lwm ib feem ntawm lub puzzle, uas qhia txhua yam thiab configures txhua lwm yam. Tebchaws qhov muag thiab ua kom pom tseeb rau lawv, tsis yog nyob rau hauv lub foreground khoom, los yog txawm lwm qhov chaw ntawm lub ntsej muag xws li lub hauv pliaj thiab qhov ntswg, kuj yog ib qho ntawm cov kev pab cuam ntawm tej kev koom ua ke. Lwm feature yog los txhim kho qhov zoo ntawm 3D-mus txog qhovtwg khoom tsiv thoob plaws lub duab cheeb tsam. RGB sensor yuav tsis tau ua kom pom tseeb rau hauv kev kawm, tab sis nws ntxiv ib txheej ntawm cov ntaub ntawv yuav tsum tau rau lub AF system. Piv txwv li, yog tias ib tug liab khoom crosses tus ncej ntawm sab laug mus rau sab xis thiab nce nyob rau hauv loj, SRS yuav ntxiv cov ntaub ntawv no mus rau lub AF-sensor cov ntaub ntawv yuav tau kho cov kom pom tseeb sai sai.

Active D-Teeb pom kev zoo

Hwj chim los ntawm cov koob yees duab roj teeb. Tus ntaus ntawv sau latitude, longitude, altitude thiab lub sij hawm nyob rau hauv EXIF- headers ntawm cov ntaub ntawv duab. GP-1 nyob rau nruab nrab, nws yuav siv sij hawm xwb 35 vib nas this mus nrhiav satellites thiab 5 nrog ib tug kub pib. Xeem khi rau lub GPS chaw nyob rau hauv cov zaub mov: Koj muaj peev xwm muab hwj huam tawm ntawm lub ntaus ntawv thaum koj tig tawm tau nphav raug metering system. Qhov no txuag roj teeb lub hwj chim, tab sis yuav tsum tau 5 rau kev cia siab tom qab qhib rua ntawm lub raug 'meter'.
