survey

imo Auto Pict ivumela ukudubula oluzenzekelayo xa ikhamera ngokwayo imisela izicwangciso efanelekileyo ngokungqinelana nemiqathango ngumsindo. photographer Ikhamera unelungelo ukukhetha enye iinketho flash eziliqela, ubungakanani isakhelo kunye nomgangatho, isantya ISO, indlela ingqalelo, kodwa zonke ezinye i parameters ibalwa kwisixhobo. Nokuba izicwangciso engagqibekanga umfoti ongenamava engahlawulwayo ayikwazi Ungakhathazeki nganto ingenguwo crosstalk kunye image lungabanjwa. imo shooting oluzenzekelayo alwa kakuhle iintlobo ngeentlobo zezinto, kodwa undoqo i camera SLR kukuba yahluke kakhulu ukusuka compact. DSLR-ikhamera yenzelwe abo bafuna ukulawula imifanekiso yabo.

Imiyalelo kokukhetha izicwangciso elilelona

Ngokusekelwe sokukhanya okukufutshane, umgama kunye nentshukumo isifundo nga ngokuzenzekelayo Ukukhetha useto eliphezulu Pentax K100D. Inkcazelo lika-amanyathelo ngolu hlobo lulandelayo:

1. Cwangcisa Mode socofo ukuya Auto Pict. Le khamera ikhetha indlela kangangoko ukuba image lungabanjwa.
2. Cwangcisa Imowdi yefocus switsha AF.
3. Ngekhamera viewfinder aqhubela sifundo. Xa ngokukhanya efanayo, ungatshintsha ubungakanani bayo ibonakale.
4. Beka isihloko ngaphakathi isakhelo kunye polunazhat iqhosha shutter. Qala ukusebenza inkqubo AF, apho isalathisi alatha focus ukugqitywa. Ukuba kuyimfuneko, i-flash eyakhelwe-ngaphakathi isekwe kwi kwindawo esebenzayo.
5. cofa ngokupheleleyo shutter iqhosha. Ukudubula lugqityiwe.
6. LCD screen zingasetyenziswa ukujonga iifoto. Emva kokuba kuthathwe lo mfanekiso, oko siboniswe nesisitheliso 1 yesibini. Kulo mzekelo, ungenza uyisusa ngokucinezela iqhosha elililo kwiqela lenjongo angasemva.

iindlela sokudubula

Zabo sesichengeni kunye beso

Ekugqibeleni, ikhamera isebenze kwindlela inkqubo (P), imo beso ephambili (Av), shutter ephambili (Tv) kunye exposure manual (M). Ezi iimpawu ibhanile nayiphi DSLR-camera. Ukongeza ufake Iqhubu (B) ukuze ukulawula ngesandla ixesha ukuvulwa shutter for aziwayo elide kakhulu. iindlela ngolu hlobo lulandelayo yokusebenza:

• P: I iiseti yekhamera isantya kunye beso ngokuzimeleyo. Lo msebenzisi uyakwazi ukutshintsha izicwangciso zayo, kuquka nokukhetha indlela flash, lungisa ukuvuleleka kunye flash camera, uhlobo yomlinganiso, AF, ukudubula, ISO novakalelo, ukulungelelana emhlophe, ubungakanani bomfanekiso nomgangatho. Ukhetho olunye ziyafumaneka ukuze Tv, imo Av, M no B.
• Isantya shutter ebekwe yi ngumsebenzisi, kunye umngxuma - camera: tv.
• Av: Umfoti ukutshintsha beso kunye exposure ikhethwa ngokuzenzekelayo.
• M: isantya shutter kunye umngxuma zisekwa ngumsebenzisi.
• B: M iyafana, ngaphandle kokuba shutter uvuliwe de shutter qhosha licinezelwe.

uBuyiselo lobekuKhethelwe

Olu phawu ivumela ukutshintsha exposure ngaphakathi ± 2 nokunyuswa eV 1/3 imo eV kuphela P, Tv kunye Av. Kakhulu ngempumelelo xa iziko-weighted okanye indawo wekhadi. Kukho kwakhona umsebenzi sesichengeni bracketing ukuze zifake izakhelo ezininzi kunye aziwayo ezahlukeneyo: Umgangatho underexposed kunye overexposed.

exposure imitha

Wosilelo imilinganiselo I K100D Super-mali lwenziwa kusetyenziswa icandelo-16 nenkqubo-zone. Ifumaneka iziko-weighted kwaye ndawo wekhadi iinketho. Multizone wekhadi jikelele isebenza kakuhle, kodwa ngamanye amaxesha bayaphoswa avelele ngeziganeko eziphakamileyo koko, ezifana isibhakabhaka eliqaqambileyo okanye ulwandle ne ilanga kubonakala kuyo. Nangona kunjalo, ezi ntsilelo zifumaneka kwezinye iikhamera digital. umehluko izigcawu High kunye ngaphezulu amanqanaba ukhanyiso ofanelekileyo kukhokelela kwiziphumo engcono.

focus

I Pentax K100D isebenzisa inkqubo AF ngongoma-11, kwaye umsebenzisi kwakhona ukhethe indawo ekugxilwe kuzo sokuzifaka okanye manual umfanekiso iveni kabukhali. Ukongeza iswitshi, ibekwe kufuphi ilens entabeni, Imowdi yefocus ungalawuleka nge yekhamera menu. ongakhetha ababini ba khona AF: olunye (AF-S) kunye ngokuqhubekayo (AF-C). Eyokuqala kwezi senzelwe izinto zokubhala kunye neebhloko ukutshintsha ingqwalasela xa shutter iqhosha licinezelwe gabhu phakathi. Elesibini lisetyenziswa izinto uhambisa kwaye ijolise ndikho gqolo licinezelwe gabhu phakathi kwinzala.

Ngokwahlukileyo iikhamera reflex nge multi-kummandla AF ezisebenzisa enye amabini kuphela okanye isivamvo cross-uhlobo asebenza zombini kwicala ethe nkqo nethe tyaba, SAFOX VIII inkqubo 9 iquka abenzi boluvo ezinjalo, nto leyo ukuchaneka enkulu emsebenzini.

ncomo User Speed Focus Pentax K100D Super ibizwa ngokwaneleyo kwaye luzimele lens eqhotyoshelweyo. AF woluvo kwakhona ibhaqa enoncedo ndikho elichanekileyo ukuwina. Nangona le modeli akanguye ngokukhawuleza kumnombo Pentax, lugxininisa phantse ukhawulezise kangangoko isiphelo ophezulu K10D camera.

Monitor kunye angeli

Pentax K100D mayixhotyiswe umboniso 2.5 "LCD Pixels kwaye adjustable kwinqanaba ukukhanya 210 lamawaka.. I sikrini ebanzi isidanga-140 ukubukela engile nkqo yaye tye, ngoko imifanekiso ingabonakaliswa ngaxeshanye kubantu ezininzi. Kwakhona kuyenzeka ulwando oluphindwe-12 kule mifanekiso. Lo mboniso akasebenzi kwimo emehlweni - awukwazi ukuyisebenzisa ukuba ibhale kuqhume. Ukulungiselela le njongo inkulu ngokwaneleyo kwaye viewfinder eliqaqambileyo 0.85 × ukukhulisa ne-96% network isakhelo. Oku kubhetele kunokuba abaninzi entry-level SLR.

flash

Integrated Flash isusela phezulu umzimba camera ngokucofa iqhosha kwiqela lenjongo umva Pentax K100D. iimpawu isibane ukuvumela nokufotwa umgama 0.7-4 m ukusuka kwisifundo ngokutsho ISO kunye nezicwangciso imbobo. 4 ziyafumaneka iindlela flash: oluzenzekelayo, manual, nokucutha-red eye ngamnye kubo.

Xa uluvo abanini, kuba indlala kuphela kukuba santya siphezulu sync ka 1/180 umzuzwana. Oku kulufanelekele sokudubula ekukhanyeni low, nokusetyenziswa kwayo emini nje yokugcwalisa flash isoloko ifuna aziwayo ka 1/500 s okanye ngaphantsi. Ngoko kuyimfuneko ukucwangcisa emngxunyeni ukuze F22 okanye ngaphezulu, nto leyo ukhetho efanelekileyo.

umbala

Kukho iindidi ezimbini ilizwi ezisisiseko yomfanekiso: eqaqambileyo zendalo, owokuqala leyo ebekwe ngokungagqibekanga. Ngokutsho umsebenzisi ingxelo, esi sicwangciso eneneni kukhokelela imibala supersaturated, ngokuzibhaka kunye ingqolowa. Ngenxa yesi sizathu, bacebisa ukuba Ukuseta ikhamera iithowuni zendalo.

Camera Pentax K100D ubandakanya i-Adobe RGB isithuba umbala, kunye sRGB. Ngelixa lokuqala yombala eveliswa sisixhobo ngokubanzi, efanelekileyo kwabasaqalayo i sRGB, njengoko kulo mzekelo, imifanekiso khangela ngokoqobo kwi-screen kwaye print ngakumbi. Imibala usisityebi, ingakumbi izabelo ebomvu kwaye uhlaza zazo. Ukuthintela imifanekiso na oversaturated, kufuneka kancinci underexpose. Ukuza kuthi ga ngoku, abasebenzisi ukucwangcisa amaxabiso -0,3 okanye -0,7 eV exposure imbuyekezo.

kwindlela yemenu ye camera kwakhona ikuvumela ukunyenyisa Ukwanda, ndikho nokulungisa lo mfanekiso.

photosensitivity

Auto ISO olungagqibekanga indawo oluzenzekelayo kunye iindlela lokudubula ngokokubona kwayo icwangcisa ISO uvakalelo ka-200 ukuya 3200. Kwakhona kuyenzeka ukuba anciphise uhla oluzenzekelayo ISO, umz, amaxabiso ka-200-800. ISO 200 indlela kwendlao kwi P, Tv, Av, kunye M, ukuba ixabiso ISO iye ingazange ekhethiweyo. Ubuntununtunu lingamiselwa ngesandla ngokukhetha enye kwezi zithethe zixabisekileyo zilandelayo: 200, 400, 800, 1600 okanye 3200.

ibhalansi emhlophe

Auto Ibhalansi emhlophe umiselwe ngokuzenzekelayo zonke iindlela ukudubula Pentax K100D. Umsebenzisi kwakhona ukukhetha isicwangciso ngenxa yale igqengezelayo, ezijiko-jiko, kwelanga ngqo, oonotsheluza, amafu, umthunzi, okanye wakhutshwa emhlophe okanye ingwevu reference into.

ubomi bebhetri

Company Pentax - enye abenzi ezimbalwa khamera SLR, nto leyo evumela ukuba ufake amabhetri AA.

Ngaphezu koko, K100D unako sinokubanamandla yi neebhetri lithium nohlobo yokusebenza elide CR-V3. Le khamera ivumela ukuba kuqhume 1480 kunye ukuxhomekeka, image sinjalo, umsebenzi ukususwa uthuli kwi siqalo nganye kwaye ngamaxesha usebenzisa kuqhuma zangaphakathi nezangaphandle.

Ukucacisa yokukhanya

I-antenna enikezelweyo 18-55 mm lens kakhulu elungileyo. Optics ubonisa omuhle engabalulekanga (iikona mnyama) kwi-engile ububanzi (18 mm), kodwa ndikho ezaneleyo lonke kwisakhelo. Ilens unesifo kancinane umphanda ubugqwetha ekupheleni ebanzi kunye pincushion kwi iTelephoto. Nangona isigqibo 6-megapixel, imifanekiso eneenkcukacha kwaye upholile, nokuba kwi-100% sikrini. Ecaleni imiphetho kukho fringing emfusa (kwimida eziphakamileyo-umahluko), kodwa ibonakala kuphela xa kabini.

reviews
