I-Lomography ivuselela inkulungwane ye-19 yePetzval lens kwiKickstarter

I-Lomography kunye ne-Zenit ese-Russia ibhengeze ubuhlakani obujolise ekuvuseleleni iilensi ezithandwayo zePetzval ngeKickstarter.

Indawo edumileyo yokuxhasa ngemali isihlwele, ebizwa ngokuba yiKickstarter, ibonakalise ukuba liqonga lokwazisa leenkampani ezininzi eziphumeleleyo. Ayisiyiyo loo nto kuphela, kodwa uninzi lweefemu ezimiselweyo ziye zagqiba kwelokuba ziqokelele imali efunekayo yokwakha imveliso ngale ndawo, ebingumbono olungileyo kubo.

IZenit kunye neLomography zibhengeze ilensi entsha yePetzval kwiKickstarter. I-optic icingelwe kwakhona kwaye iya kubandakanya ubude be-85mm kunye ne-f / 2.2 ukuvula.

Elinye ibali elinethamsanqa lelo leLomography, ebeyinkampani edumileyo ngaphambi kokuvela kweKickstarter. Kulo nyaka, i Isikena sefilimu ye-Lomography ixhaswe ngemali kweli qonga.

Ngoku, umbutho ubuyile kwiKickstarter, kodwa ngeprojekthi ebaluleke ngakumbi: ukuvuswa kwelensi yePetzval.

Uyilo lwenziwe ngokubambisana neZenit yaseRussia, eya kuthi iphinde ivelise i-optic kwilizwe labo.

UJoseph Petzval ngumvelisi welensi yePetzval ngo-1840. Unjingalwazi wezibalo uye wayiguqula ngokupheleleyo imifanekiso yokufota, njengoko ilensi yakhe yayikwazi ukuvelisa i-bokeh yemilingo.

Iilensi zePetzval ziye zaphuhliswa ngo-1840 nguprofesa wezibalo onegama elifanayo: uJoseph Petzval. Le mveliso iyitshintshe ngokupheleleyo imifanekiso yokufota, njengoko ikwazile ukufezekisa i-af / 3.5 aperture. Ukuba nembobo ebanzi kwenza iifoto zibonise i-bokeh enomtsalane. Ngeli xesha, yenza iziphumo ezimangalisayo, ngelixa kunciphisa amaxesha okuvezwa kangangeendawo ezintlanu zokuma.

Nangona kunjalo, le lens ivelisa iziphene ezibonakalayo, ezinje nge-vignetting. Nangona kunjalo, ubunzulu obuncinci bentsimi obudityaniswe ne-vignetting eninzi bunokubangela iziphumo zomlingo.

Iilensi zePetzval ziya kusebenza kuphela ngeekhamera zeNikon F kunye neCanon EF SLR, nokuba ziyi-analog okanye yidijithali.

I-Lomography kunye neZenit ityhile ukuba ilensi yePetzval yenzelwe ukuba iphinde isetyenziswe kubadubuli banamhlanje. Imveliso iya kuhambelana neekhamera zeNikon F kunye neCanon EF, zombini i-analog kunye nedijithali.

Ingaphandle liya kwenziwa ngobhedu, njengenguqulelo yoqobo, kwaye useto luya kulawulwa ngesandla. Oku kuthetha ukuba akukho nkxaso ye-autofocus, ngelixa abafoti nabo kuya kufuneka batshintshe ukuvula ngesandla. Isilayidi sokuvula sibizwa ngokuba sisiXokelelwano samanzi, ekungafanelekanga ukuba kube nzima ukusisebenzisa.

Iilensi zeLomography Petzval ziya kubandakanya ubude be-85mm kunye ne-f / 2.2 ephezulu yokuvula, enokuncitshiswa ibe f / 16. Ukongeza, iya kuba nakho ukugxila kumgama wemitha enye, ngelixa icandelo lokujonga liza kuma kuma-30 degrees.

Umkhankaso weKickstarter uyifezekisile injongo yawo, ukuhambisa ngenqanawa kuqala ngasekupheleni kuka-2013

Ixabiso layo libekwe kwi-300 yeedola, kodwa zii-100 kuphela zeentaka zokuqala ezikwazileyo ukuyithenga ngale mali. Ngoku, abasebenzisi banokuyifumana kwi- $ 350 kunye ne- $ 400 okanye ngaphezulu.

I-Pentzval optic entsha iya kuqala ukuthengiswa ngoFebruwari 2013 nge-499 yeedola, oko kuthetha ukuba kuya kufuneka ukhusele iyunithi ngoku okanye awuyi kuzisola kamva. Kubalulekile ukuba uqaphele ukuba ibhetshi yokuqala iya kuthumela ukuphela kuka-2013.

I-Lomography kunye neZenit Sele ndidibene ne-100,000 zeedolal. Zimalunga neentsuku ezingama-29 ezishiyekileyo de ufumane imveliso kwiKickstarter kwaye ngekhe kumangalise ukuba iphulo lifikelela kwi-1 yezigidi zeedola ngexesha liphela.
