Amalensi we-Irix 15mm f / 2.4 amenyezelwe ama-DSLR ozimele ogcwele

U-Irix wethule ilensi ebizwa ngephupho lomthwebuli zithombe. Iqukethe i-15mm f / 2.4 wide-angle prime ngokugxila okwenziwa ngamakhamera we-DSLR ogcwele.

Inkampani eyodwa edume ngokwethula i-manual-focus-only optics enekhwalithi ephezulu yesithombe yama-DSLRs azimele ngokugcwele yiZeiss. Umenzi waseJalimane uphinde akhiqize amalensi e-autofocus, kepha manje unembangi ebucayi kulayini wayo wokugxila mathupha.

Umncintiswano uqhamuka kwa-Irix, osanda kususa okusongelwe i-wide-angle optic enobude obugxile ku-15mm nokuvulwa okuphezulu kwe-f / 2.4. Umkhiqizo uzokhishwa kulo nyaka we-Canon, Nikon, ne-Pentax DSLRs, kodwa okokuqala, ake sibone ukuthi yini ongayinikeza.

Ukukhishwa kwabezindaba kuthi ilensi ye-Irix 15mm f / 2.4 iza igcwele ubuchwepheshe obusha. Amasistimu afakwe ku-optic kuthiwa athatha ukusebenza okugxilwe ngesandla kuya ezingeni elilandelayo, njengoba abasebenzisi bazoba nokukhiya okugxile, isikali se-hyperfocal, kanye nokuchofoza okungapheli abanakho.

I-Irix 15mm f / 2.4 wide-angle prime lens inikeza ubuchwepheshe obusha, ukusebenza kahle kwe-optical, nokubekwa kwesimo sezulu.

I-Focus lock isici esivumela abasebenzisi ukuthi bakhiye iringi yokugxila. Ingasetshenziswa ngabathwebuli bezithombe lapho benesiqiniseko sokuthi bagxile kahle, ngakho-ke bazofuna ukuthi iringi yokugxila ihlale isendaweni.

Isikali se-hyperfocal sikhona ukukhombisa abasebenzisi ukujula kwensimu yokuvula okukhethiwe, ngenkathi ukuchofoza okungapheli kwenza umsindo wokuchofoza lapho abathwebuli bezithombe bebeka ukugxila kokungapheli. Ngale ndlela, abasebenzisi bazokwazi lapho ilensi yabo igxile kokungapheli.

Ilensi ye-Irix 15mm f / 2.4 inikeza ikhwalithi yesithombe ephezulu

Esinye sezici ezibaluleke kakhulu zelensi ikhwalithi yesithombe sayo. Ilensi ye-Irix 15mm f / 2.4 yenza okungajwayelekile kulo mnyango, njengoba kushiwo kwabezindaba.

Kuza nokucushwa kwangaphakathi okuyinkimbinkimbi okuqukethe izinto eziyi-15 emaqenjini ayi-11. Ama-trio wezinto ahlinzeka ngenkomba yokubonisa ephezulu, kuyilapho ezimbalwa zazo ziyizinto ze-Extra-Low Disperion.

Izinto ezimbili ezengeziwe zingumbumbulu, ngakho-ke yonke inhlanganisela inciphisa kakhulu ukuphambuka kwe-chromatic nokuphazamiseka, ngenkathi kukhuphuka ukukhanya okuya emaphethelweni. Ngokwengeziwe, le optic ifaka ingubo ye-neutrino enciphisa ukugqashuka nomoya.

Abasebenzisi beCanon, Nikon, nePentax bazokwazi ukuyithenga entwasahlobo ka-2016

Ilensi ye-Irix 15mm f / 2.4 ibekelwe isimo sezulu, okusho ukuthi ivikelwe emswakeni, ekuphazanyisweni, nasothulini lapho isetshenziswa ngokuhlangana nekhamera evaliwe.

I-prime-angle prime izokhishwa ngezinhlobo ezimbili: iBlackstone, eqoshwe ukumakwa kwe-fluorescent nomzimba owenziwe nge-aluminium ne-magnesium, neFirefly, eneringi egxile kakhulu ku-ergonomic kanye nokwakhiwa kwe-ultra-lightweight.

IBlackstone izokala amagremu angama-685 ngentaba yeCanon nama-653 amagremu ngentaba yeNikon, kuyilapho iFirefly izokala amagremu angama-608 kumakhamera weCanon futhi, ngokulandelana, ibe ngamagremu angama-581 amakhamera eNikon.

U-Irix ukuqinisekisile ukuthi i-optic izotholakala ku-Canon EF, Nikon F, naku-Pentax K mounts. Ilensi izokhishwa ngesinye isikhathi kule ntwasahlobo ngenani lentengo elingamenyezelwe.
