Abafaki bobabini be-Sigma kunye ne-Micro Four Thirds system banokubakho kwiindlela ezimbalwa zokuphatha kwixa elizayo. Enye yazo yi-Sigma 35mm f / 2 DN OS Art lens, enelungelo elilodwa lomenzi eJapan.

Iilensi ziyilelwe kwiikhamera ezingenazipili kunye nee-Micro Four Third sensors. Inendawo evulekileyo yokuvula ukuze ibe luncedo ngaphakathi okanye ngaphandle xa ukukhanya kungalunganga. Ngaphaya koko, iza ipakishwe ngetekhnoloji yozinzo lomfanekiso ophuculweyo ukuphucula ukubanako kokukhanya okuphantsi.

Njengesiqhelo, abafoti baya kuthathela ingqalelo imeko yesityalo, oko kuthetha ukuba i-optic iya kubonelela ngesakhelo esigcweleyo esilingana ne-70mm. Iwela kwicandelo elifutshane lomnxeba, ke ubukho benkqubo yokuchazwa kwemifanekiso ekhankanywe apha ngasentla yamkelwe kwakhona. Ngale ndlela, ukuba iyafumaneka kwintengiso, emva koko i-Sigma 35mm f / 2 DN OS Art lens iya kuba luncedo ekufotweni kwemifanekiso, nayo.

Ukusetyenziswa kwelungelo elilodwa lomenzi kutyhila ukuba ilensi iza nezinto ezilithoba kumaqela asibhozo. Inkqubo yokugxila ngaphakathi ikhona kuyilo, ke ngoko umphambili awuyi kuhamba xa ugxile.

Le optic iya kulinganisa malunga ne-58mm, ke ayizukuba yilensi enkulu. Ngapha koko, iya kuba incinci kakhulu kwaye kunokwenzeka ukuba ubunzima bayo bugcinwe phantsi kolawulo, ukuvumela abasebenzisi abangenazipili ukuba bajonge ekuthatheni iifoto kunokuba bacatshukiswe bubunzima bayo.

I-Sigma 35mm f / 2 DN OS Art lens patent yafakwa nge-21 kaNovemba ngo-2013, ngelixa imvume yayo yanikezelwa nge-4 kaJuni, 2015. Akukho mhla wokukhutshwa ukhombisiwe kumzi-mveliso we-rumor, nangona singafanele simangaliswe xa sisiva ngaphezulu malunga nayo kwiinyanga ezili-12 ezizayo.
