Njengoba kwaziwa, yethu 57x 850mm ubude-ikhamera yokusondeza ububanzi incane ngosayizi (ingama-32cm kuphela ubude, kuyilapho imikhiqizo efanayo ngokuvamile ingaphezu kuka-40cm), ilula ngesisindo (i-6.1kg emikhiqizweni efanayo, kuyilapho umkhiqizo wethu ingu-3.1kg), futhi iphakeme ngokucaca (cishe ngo-10% phezulu kulayini wokuhlola ukucaca ) uma kuqhathaniswa nohlobo olufanayo lwelensi yokusondeza enenjini engu-775mm. Ngaphandle kobuchwepheshe bokuxhumanisa ama-multi-group kanye nomklamo odidiyelwe, enye into ebaluleke kakhulu ukusetshenziswa kwe-aspherical lens design.

Yiziphi izinzuzo zokusebenzisa amalensi aspherical kumalensi e-telephoto?

Ukuqeda ukuphuma okuyindilinga

Amalensi ayindilinga angabangela ukuphuma okuyindilinga, okusho ukuthi ikhwalithi yesithombe engahambisani phakathi kwesikhungo namaphethelo welensi. Amalensi aspherical angakwazi ukulungisa lokhu kuphenduka okuyindilinga, okuholela ekucabangeni okucacile nokufanayo.

Ukuthuthukisa ikhwalithi yokubona

Amalensi aspherical angathuthukisa ikhwalithi yesistimu ye-optical, okwenza ukuthwebula kucace kakhudlwana. Banganciphisa ukuphambana okufana nekhoma, ukugoba kwenkundla, nokuphambuka kwe-chromatic, ngaleyo ndlela kuthuthukiswe ukunemba kwesithombe nokuvumelana.

Ukwandisa ukulungiswa

Ukusetshenziswa kwamalensi e-ofpherical kukhulisa ukucaca, okuvumela ukuboniswa okuningiliziwe kwemininingwane. Banganciphisa ukuhlakazeka kokukhanya kanye ne-chromatic aberration, ngaleyo ndlela bathuthukise ukucaca kwesithombe nokuba bukhali.

Ukunciphisa isisindo kanye nosayizi welensi

Uma kuqhathaniswa namalensi ayindilinga endabuko, amalensi aspherical angaba mancane, ngaleyo ndlela ehlise isisindo nosayizi welensi, enze okokusebenza kwekhamera kube lula futhi kuphatheke kalula.

Ukwandisa ukuguquguquka ekwakhiweni kwamalensi

Ukusetshenziswa kwamalensi aspherical kunikeza abaklami bamalensi inkululeko eyengeziwe nokuguquguquka. Angaklanywa ngokuya ngezidingo ezithile zezithombe ukuze kuzuzwe imiphumela engcono yokucabanga.

Kafushane, ukusetshenziswa kwamalensi aspherical kungathuthukisa ikhwalithi yesithombe, kukhuphule ukulungiswa, kunciphise isisindo nosayizi, futhi kunikeze ukuguquguquka okukhulu ekwakhiweni kwamalensi. Lezi zici zizenza zibe ingxenye ebalulekile kumalensi e-telephoto.

Ngesikhathi esifanayo, ama-lens aspherical ayabiza kakhulu, ngakho-ke namuhla ama-lens amaningi okusondeza kagesi awasebenzisi ama-aspherical lens ukuze anciphise izindleko.
