Magalasi aku mafakitale amagwiritsidwa ntchito kwambiri m'mafakitale ndipo ndi amodzi mwa mitundu yodziwika bwino.Mitundu yosiyanasiyana ya magalasi ogulitsa mafakitale imatha kusankhidwa malinga ndi zosowa zosiyanasiyana komanso mawonekedwe ogwiritsira ntchito.

Momwe mungagawire magalasi a mafakitale?

Magalasi a mafakitaleakhoza kugawidwa m'mitundu yosiyanasiyana malinga ndi magulu osiyanasiyana.Njira zodziwika bwino zamagulu ndi izi:

Gulu lotengera kapangidwe ka mandala. 

Malinga ndi ma lens a mandala, magalasi akumafakitale amatha kugawidwa m'magalasi amodzi (monga ma lens owoneka bwino, ma concave ma lens), ma lens apawiri (monga ma lens a biconvex, ma lens a biconcave), magulu amagulu osiyanasiyana, ndi zina zambiri.

Zosankhidwa molingana ndi kutalika kwapakati.

Zosankhidwa molingana ndi kutalika kwa lens,magalasi a mafakitalezikuphatikizapo magalasi otalikirapo, ma lens wamba, ma telephoto lens, ndi zina.

Amasankhidwa molingana ndi madera ofunsira.

Zosankhidwa molingana ndi magawo ogwiritsira ntchito ma disolo, magalasi a mafakitale amatha kugawidwa m'magalasi owonera makina, magalasi oyezera mafakitale, magalasi oyerekeza zamankhwala, magalasi a microscope, ndi zina zambiri.

Zosankhidwa molingana ndi mtundu wa mawonekedwe.

Zosankhidwa molingana ndi mawonekedwe a mawonekedwe a mandala, ma lens a mafakitale akuphatikizapo C-mount, CS-mount, F-mount, M12-mount ndi mitundu ina.

Kugawika kutengera mawonekedwe a kuwala.

Magalasi amagawidwa molingana ndi magawo awo owoneka bwino, kuphatikiza kutalika kwapakati, kabowo, malo owonera, kupotoza, astigmatism, kusamvana, etc.

Lens ya mafakitale

Kodi pali kusiyana kotani pakati pa magalasi a mafakitale ndi ma lens onse?

Ndi kusintha kwa kufunikira ndi kupita patsogolo kwaukadaulo, kusiyana kwa magwiridwe antchito pakatimagalasi a mafakitalendipo magalasi ogula wamba akuzimiririka pang'onopang'ono, ndipo ma lens ena amakampani ndi ma lens wamba amathanso kugwiritsidwa ntchito mosinthana.Nthawi zambiri, kusiyana pakati pa magalasi a mafakitale ndi ma lens wamba ndi motere:

Osiyana kuwala katundu

Poyerekeza ndi magalasi wamba, magalasi akumafakitale ali ndi zofunikira zapamwamba zamtundu wazithunzi komanso kulondola.Nthawi zambiri amakhala ndi kupotoza pang'ono, chromatic aberration ndi attenuation kuwala, kuwonetsetsa kulondola kwazithunzi komanso kudalirika.Magalasi anthawi zonse amatha kukhala ndi zosokoneza pazigawo zina, makamaka kutsata ukadaulo wapamwamba komanso luso la ogwiritsa ntchito.

Zolinga zamapangidwe osiyanasiyana

Magalasi a mafakitaleamapangidwa makamaka kuti azigwiritsidwa ntchito m'mafakitale monga masomphenya a makina, kuwongolera makina, kuyeza ndi kusanthula.Zapangidwa kuti zigwirizane ndi kulondola kwakukulu, kusamvana kwakukulu ndi zofunikira zokhazikika.Magalasi anthawi zonse amapangidwa makamaka kuti azijambula, mafilimu ndi makanema apawayilesi, ndipo amalabadira kwambiri momwe zithunzi zimagwirira ntchito komanso luso lazojambula.

Njira zosiyanasiyana zowunikira

Magalasi ambiri nthawi zambiri amakhala ndi autofocus ntchito, yomwe imatha kusintha mawonekedwe malinga ndi zomwe zikuchitika komanso mutuwo.Magalasi akumafakitale nthawi zambiri amagwiritsa ntchito kuyang'ana pamanja, ndipo ogwiritsa ntchito amayenera kusintha pamanja kutalika kwake ndikuyang'ana kuti agwirizane ndi zochitika ndi zosowa zosiyanasiyana zamakampani.

Kusiyana kwa durability ndi kusinthasintha

Magalasi a mafakitaleamafunika kupirira madera ovuta a mafakitale, monga kutentha kwakukulu ndi kutsika, chinyezi ndi kugwedezeka, choncho nthawi zambiri amafunika kukhala olimba komanso osinthika.Poyerekeza, ma lens ambiri amapangidwa kuti azikhala opepuka, osavuta kunyamula komanso osavuta kunyamula, kuwapangitsa kukhala osavuta kugwiritsa ntchito m'malo abwinobwino.
