Kodi Ma Lens A mafakitale Angagwiritsidwe Ntchito Ngati Magalasi a SLR? Ndi Ma Parameter ati Oyenera Kusamala Posankha Ma Lens Amakampani?

1,Kodi magalasi aku mafakitale angagwiritsidwe ntchito ngati magalasi a SLR?

Mapangidwe ndi ntchito zamagalasi a mafakitalendi magalasi a SLR ndi osiyana. Ngakhale onse ndi magalasi, momwe amagwirira ntchito komanso momwe amagwiritsidwira ntchito adzakhala osiyana. Ngati muli m'malo opanga mafakitale, ndi bwino kugwiritsa ntchito magalasi apadera a mafakitale; ngati mukugwira ntchito yojambula, tikulimbikitsidwa kugwiritsa ntchito magalasi aukadaulo a kamera.

Magalasi a mafakitale amapangidwa molunjika pa kulondola, kulimba, ndi kukhazikika, makamaka kuti akwaniritse zosowa za kupanga ndi ntchito zina zaukadaulo, monga kugwiritsa ntchito mwachindunji, kuyang'anira, kafukufuku wamankhwala, ndi zina zambiri.

Kapangidwe ka magalasi a SLR makamaka amayenera kuganizira za magwiridwe antchito, mawonekedwe aluso komanso luso la ogwiritsa ntchito, ndi zina zambiri, kuti akwaniritse zosowa za ojambula pazithunzithunzi komanso magwiridwe antchito aluso.

Ngakhale ndizotheka kukhazikitsa lens ya mafakitale pa kamera ya SLR (malinga ndi mawonekedwe ake), zotsatira zowombera sizingakhale zabwino. Ma lens akumafakitale mwina sangakupatseni chithunzi chabwino kwambiri kapena magwiridwe antchito, ndipo mwina sangagwire ntchito ndi kamera yanu yodziwonetsa yokha kapena makina olunjika.

Pazofuna zina zapadera zojambulira, monga kujambula kwapang'ono pang'ono, ndizotheka kuyikamagalasi a mafakitalepa makamera a SLR, koma izi nthawi zambiri zimafunikira zida zothandizira akatswiri ndi chidziwitso chaukadaulo kuti athe kumaliza.

2,Ndi magawo ati omwe tiyenera kusamala posankha magalasi a mafakitale?

Posankha mandala a mafakitale, muyenera kuganizira magawo osiyanasiyana. Ma parameter awa nthawi zambiri ndi omwe amayang'ana kwambiri:

Kutalika kwapakati:

Kutalika kwapakati kumatsimikizira gawo la mawonedwe ndi kukula kwa lens. Kutalika kwapang'onopang'ono kumapereka mawonekedwe otalikirapo ndi kukulitsa, pomwe utali wocheperako umapereka mawonekedwe ochulukirapo. Nthawi zambiri timalimbikitsa kusankha kutalika koyenera koyang'ana kutengera zosowa za zochitika zinazake zogwiritsa ntchito.

Pobowo:

Khomo limatsimikizira kuchuluka kwa kuwala komwe kumaperekedwa kudzera mu lens komanso kumakhudza kumveka bwino ndi kuya kwa chithunzicho. Kabowo kakang'ono kamalola kuwonetseredwa bwino ndi mawonekedwe azithunzi mukamawala pang'ono. Ngati kuunikira kwa malo omwe mukuwomberako kumakhala kofooka, tikulimbikitsidwa kusankha mandala okhala ndi kabowo kakang'ono.

Kusamvana:

Kusintha kwa lens kumatsimikizira tsatanetsatane wa chithunzi chomwe chingajambule, ndi malingaliro apamwamba omwe amapereka zithunzi zomveka bwino, zatsatanetsatane. Ngati muli ndi zofunikira zapamwamba kuti muwonetsetse bwino zithunzi zomwe zajambulidwa, tikulimbikitsidwa kusankha mandala apamwamba kwambiri.

Mawonekedwe:

Malo owonera amatanthauza kuchuluka kwa zinthu zomwe disolo limatha kuphimba, zomwe nthawi zambiri zimawonetsedwa m'makona opingasa komanso ofukula. Kusankha gawo loyenera lowonera kumatsimikizira kuti mandala amatha kujambula chithunzi chomwe mukufuna.

Mtundu wa mawonekedwe:

Mtundu wa mawonekedwe a lens uyenera kufanana ndi kamera kapena zida zomwe zimagwiritsidwa ntchito. Wambamafakitale mandalaMitundu ya mawonekedwe imaphatikizapo C-mount, CS-mount, F-mount, etc.

Kupotoza kumatanthawuza kupunduka komwe kumayambitsidwa ndi mandala akamajambula chinthu pamtundu wa photosensitive element. Nthawi zambiri, magalasi a mafakitale amakhala ndi zofunika kwambiri pakupotoza. Kusankha lens ndi kupotoza pang'ono kungatsimikizire kulondola ndi kulondola kwa chithunzicho.

Ubwino wa mandala:

Mawonekedwe a mandala amakhudza mwachindunji kumveka bwino komanso kutulutsa mtundu wa chithunzicho. Posankha mandala, muyenera kuonetsetsa kuti mwasankha mtundu wa lens wapamwamba kwambiri ndi chitsanzo.

Zofunikira zina zapadera: Posankha magalasi a mafakitale, muyeneranso kuganizira ngati malo omwe amagwiritsidwa ntchito ali ndi zofunikira zapadera za lens, monga ngati ilibe madzi, yopanda fumbi, komanso kutentha kwambiri.

Malingaliro Omaliza:

ChuangAn wachita mapangidwe oyambirira ndi kupanga magalasi a mafakitale, omwe amagwiritsidwa ntchito pazinthu zonse zamakampani. Ngati mukufuna kapena muli ndi zosowa zamagalasi a mafakitale, chonde titumizireni mwamsanga.
