Kunzwisisa Matanho Okuenzanisa Akabatanidzwa neLens Rumwe Nese
Paunenge uchiita shanduko kubva kune imwe nzvimbo uye kupfura makamera kuenda kuDVDLRs kana kuti mirroras inogona kushandurudzwa lens cameras (ILCs), chimwe chinhu chekhamera yemashanduri inogona kushandiswa iyo inogona kuvhiringidza inonzwisisa hutano hweterefhoto zoom lens, uyewo kuti inoshanda sei.
Kunyange zvazvo shanduro inoshandiswa kuyera telephoto inowanikwa mune zoom lens yekamberi yeramera inogona kushandiswa yakafanana nenzira iyo iwe unotarisa mararamiro e-zoom lens pane imwe nzvimbo uye kupfura (kana kugadzirisa lens) kamera, pane zvimwe zvakasiyana munzira iyo nhamba inoratidzirwa iyo inogona kutungamirira kune kumwe kuvhiringidzika.
Ramba uchiverenga kuti uwane kunzwisisa kwakanakisisa kwokuti ungayera sei telephoto zvigadziro zve lens yako inogona kushandurana maererano nezvingave wakambove nazvo newakagadzirisa lens kamera! (A zoom lens inorudzi rwe lens iyo inogona kutora pane multiple focal lengths, inosanganisira prime lens iyo inogona kupfura pane imwe chete yakakwirira.)
Kushandura kusvitsa pane
Nekona yakagadzirwa lera kamera, iwe unogona kunge wakanga uine ring yezhizha yakakomberedza bhenji yevharivha kana kuti shanduko yekutsvaira kumushure kwekhamera. Dhinda pikiso yezhizha imwe nzira yekufambisa kurera kusvika kune imwe telephoto setting, uye fungai iyo neimwe nzira kuti uwedzere zvimwe zvepamusoro-soro yekugadzirisa.
Ne DSLR kana mirrorless ILC model, iwe unogona kushandura kuronga kwekutsvaira nekukanganisa rwonzi rwekunyorera pane lens pachayo. Zvishomanana zvakagadzirwa neDLRLR type makamera zvinopa simba rekutsvaga sarudzo, iyo inokubvumira kushandisa shanduko kuti ufambise mberi kwekutsvaga, asi zvinoenderana nemhando uye mararamiro e lens uye kamera waunayo.
Focal urefu urefu wekuyera
Paunenge uchiedza kutsvaga hurefu hwehurefu hwezvesvositi, unowanzoona mazita akanyorwa sechikamu chezita re lens. Somuenzaniso unogona kuona lens rine marefu 25-200mm neDLRLR kana mirrorless ILC.
Nechocho uye kupfura kamera, kuyerwa kwehukuru hukuru hwezverikisi lens yakafanana, kuratidza huwandu. Zvisinei, urwu urwu haruna kunyorwa sechikamu chezita rekamera. Iwe unofanirwa kutarisa huwandu hwekamera yekunyora mazita akawanda nguva. Fixed lens maker maker chete haashandisi zvakanyanya ichi chiyero mune zvokugadzira zvinhu.
Optical zoom measurement
Nechocho uye kupfura kamera, iyo inowanzoshandiswa kuenzanisa kuratidza hukuru hwehurefu hwekamera yekusimudzira lens is optical zoom measurement. Ichi chiyero chichanyatsokurudzirwa muzvinhu zvekutsvaga, uye zvinoratidzwawo pane zvakataurwa. (Nechikonzero chacho uye kupfura kamera iyo inotarisa urefu hwemarefu yakawanda inowanikwa mazita mushure mekutsvaga kwekutsvaga mune zvinyorwa.)
Iko kusvitsa kwemaziso kunowanzosanangurwa senhamba inoteverwa netsamba X. Saka kamera inogona kunge yakagadzirisa zviso zve 8X.
Icho chiyero chekuyera hachiwanzoratidziki muzvinhu zvokutengeserana zve lens inopwanyika, kunyange zvingave. Kuti uverenge kutarisa kwemaziso kune imwe lens inogona kugoverana inongoparadzanisa yakareba telephoto focal urefu apo lens inogona kutora mufananidzo (zvakadai se 200mm mumuenzaniso wakanyorwa pamusoro) nepamusoro-soro pangara yakareba ye lens (25mm mumuenzaniso uri pamusoro) . Saka 200 yakaparadzaniswa ne25 yaizopa maziso ekutengesa 8X.
Kuwana hove huru yekutsvaira
Kazhinji mutambo uri pane yakagadzirirwa lera kamera ichakupa hurukuro yepamusoro yepamusoro pane zvaunogona kuwana neyese yekusimudzira lens yakagadzirirwa kamberi yeramera inoshandiswa . Saka kana iwe une 25X optical zoom lens nehope yako uye tema kamera, usatarisira kudzokorora muyero iwoyo mumutambo wako wakashandura unotenderera, nokuti mari inenge isina kubvumirana nemhando iyoyo yemarara.
