Okuchaza "omabonakude 30x60"? Indlela ukucacisa kaningi omabonakude

Esikhathini sethu, e abafisa ukuthenga eliphezulu yesimanje omabonakude Maningi amathuba. Kukhethwa izindlela ezihlukahlukene kusukela abakhiqizi kuphezulu kakhulu, kuhlanganise ezitolo inthanethi. Kodwa kungcono kakhulu ukuba ukhethe nguye ekufanele ku nemingcele lobuchwepheshe kanye ngesikhathi esifanayo uhlele ngentengo.

Idivayisi iyona kunalokho nzima ngobuchwepheshe, futhi umthengi isilinganiso ngesinye isikhathi kunzima ukuthi iqonde izici zayo. Ngokwesibonelo, lokho kusho "omabonakude 30x60"? Ake sizame ukuthola.

Yiziphi omabonakude

Ukuthola ukuba ukukhetha, nquma ukuthi asondele kuwe ngokwanele ukuba agcine, kungakhathaliseki ukuthi usebenzisa idivayisi hhayi kuphela ekukhanyeni elikhanyayo, kodwa lapho kuhlwa, uma uhlele inguqulo enesisindo esilula, okuyinto cishe nokunwetshiwe observation? Ngesikhathi esifanayo 30x60 omabonakude Izibuyekezo zingase zishintshe kakhulu kuye ngezidingo yomnikazi.

Ngakho-ke, kubalulekile ukuba unqume ukuthi iyini uthenga kulo mkhiqizo futhi izimo lapho bazobambisana ukusebenzisa.

Izingilazi zokubuka kungaba waseshashalazini nakwezempi, asolwandle noma embonweni wasebusuku, kanye icwecwe encane - okwamanje enkundleni ngesikhathi mncintiswano. Noma, kunalokho, esikhulu, eyenzelwe izazi zezinkanyezi kokubona. Ngamunye zilwane - izici zabo. Ngezinye izikhathi bayehluka khulu. Ukuze wenze ukukhetha okuhle, simazi kangcono ayinhloko.

Kuyini kaningi?

Lena - esinye sezici ezibaluleke kakhulu sedivayisi ezifana omabonakude. Kaningi kusitshela ikhono ukwandisa imvelo. Uma, ukwenza isibonelo, sibalo sakhe - 8, e kakhulu into eduze waphawula wena izobonwa at ibanga kancane kasi- 8 kunalokho lapho empeleni.

Lwela ukuthenga idivayisi ephakeme kakhulu ukukhulisa akanangqondo. Lesi sibalo kufanele ezihlobene izimo nendawo ukusetshenziswa omabonakude. Ukuze uthole okunye emkhakheni wanquma ukusebenzisa amasu nge izibalo kaningi 6 kuya 8. Ukwanda omabonakude izikhathi 8-10 - umkhawulo lapho kungenzeka ukuba bagcine nalo. Uma-ke ingaphezu - ukuvimbela jitter, landa yokukhanya efanayo.

Izingilazi zokubuka ne nokwanda okuphawulekayo (15-20 nesibaya) asetshenziswa ngokuhlanganyela tripod lapho benzelwe ngokusebenzisa adaptha ekhethekile noma i-adaptha. Baningi isisindo nobukhulu balezi akudingeki ukugqoka eside futhi ezimweni eziningi akudingekile, ikakhulukazi uma Ukubuyekeza nzima izithiyo eziningi.

Available in onobuhle nge kaningi variable (Pancratic). I degree of ukwanda kulezi washintsha ngesandla, efana lens lokushicilela. Kodwa ngenxa yokuba yinkimbinkimbi kakhudlwana idivayisi ezibizayo.

Okuchaza "omabonakude 30x60", noma ukukhuluma mayelana ubukhulu lens

Ukumaka Binocular yakhiwa imuphi usayizi ubukhulu lens yayo phambi lens, okuyinto kuqhutshwa ngokushesha ngemva isilinganiso inkomba. Ngokwesibonelo, lokho kusho "omabonakude 30x60"? Ngakho, lezi izibalo ukukhishwa: 30x - sibalo kaningi, 60 - usayizi ubukhulu lens mm.

Kusukela ububanzi we izinga lens isithombe kuncike. Ngaphezu kwalokho, bazimisele umthamo wokukhanya eqoqwe yinoma lens omabonakude - kuba ebanzi, ububanzi emikhulu. izimo Universal for omasha omabonakude kubhekwe esinelebuli 6x30, 7x35, noma okungenani 8x42. Uma uhlela ngesikhathi sasemini ukubukisisa imvelo, futhi kubhekwa izinto sasivumela elikude, athathe idivayisi nokwanda 8 noma 10-nesibaya, futhi lens ububanzi 30 kuya 50 mm. Kodwa lapho kuhlwa, awayona ngempumelelo kakhulu ngenxa ukukhanya kancane angangeni lens.

I omabonakude kangcono ezibukelini kwemidlalo - encane (ephaketheni version) nge kwemigomo mayelana 8h24, zingabantu awunankinga yokwenze epulanini.

Uma ukukhanya akwanele

Ezimweni ukukhanya ongaphakeme (lapho kuhlwa noma entathakusa) kufanele noma uthanda kudivayisi ezinkulu lens ubukhulu noma umhlatshelo kaningi. Isilinganiso elilungile kungenzeka 7x50 noma 7h42.

Iqembu ahlukene - okubizwa ngokuthi ubusuku-izibuko - yekwentiwa embonweni wasebusuku amadivaysi. Ngo-lens yokwenziwa unikezwe enamathela multilayer ukuthi aqede ukukhanya. Zisetshenziswa khona ukukhanya ubuncane (isib unyezi). Amadivayisi asebenzayo futhi usebenze ebumnyameni ephelele, njengoba amaza okushisa sisetshenziswa kubo. Minus zabo - ukuncika kwamandla.

Lovers ukufunda izinto cosmic (isib, cabanga sezwe we ebusweni kwenyanga) kudingeka omabonakude wawunamandla ngokwanele, nokwanda okungenani 20x. Ukuze uthole amaziyo olunemininingwane ethe xaxa nge esibhakabhakeni ebusuku sezinkanyezi esiyimfundamakhwela kungcono ukuthatha isibonakude, lokukhulunywa ngako kulendzaba ngeke esikhundleni ngisho omabonakude engcono.

Uyini engela wokubuka?

Engela umbono (noma ensimini) - esinye futhi isici esibalulekile. Lokhu value simele ububanzi amazinga Ukusabalala. Lokhu ipharamitha kuyinto inversely ukwanda engaphansi - omabonakude inikwa amandla yi abe "umbono" amancane.

Ukuba wokubuka engela omabonakude elikhulu ukubizwa ngokuthi kabanzi-angle (noma widefield). Ziyakwazi kulula ukuthatha ezintabeni, ukuze Orient kangcono ngokwabo emkhathini.

Ngokuvamile ingxenye esebenzayo sivezwe engela hhayi letihlungiwe futhi ububanzi umugqa noma isikhala, okungase kubhekwe on ibanga esezingeni 1000 m.

Ezinye izici ze-omabonakude

I ububanzi ophumayo umfundi ubizwa ngokuthi quotient ka ububanzi we umfundi yokungena kwi isilinganiso ezidlula. Okungukuthi, ne omabonakude 6x30 kokuphawula lo sibalo - 5. Isibalo esincane, kuleli cala - cishe 7 mm (ubukhulu umfundi womuntu).

Okuchaza "omabonakude 30x60" kuleli cala? Iqiniso lokuthi ubukhulu ophumayo umfundi e kophawu ezinjalo kuba 2. izibuko okunjalo ayifanele observation eside kakhulu izibani okuhle bese nazo amehlo ukukhathala uhlobo. Uma izibani ayiyinhle, noma okwashiwo baqhubeka, lesi sibalo kufanele okungenani 5, mhlawumbe 7 noma ngaphezulu.

Enye - beso "ophethe" ukukhanya nesithombe. She - ngokulingana ngqo ububanzi ophumayo umfundi. inombolo Abstract, esibonisa ke, ilingana skwele ubukhulu bayo. nesifiso sokuba lokhu izinga engengaphansi kwengu-25 ngaphansi kwezimo ukukhanya esincishisiwe.

Into elandelayo - focus. Ukuba emaphakathi, kuba - indlela jikelele imimese okusheshayo. Isilawuli ngaleyo ndlela itholakala eduze lomnyango yokuxhuma ipayipi. Ukugqoka izibuko kuyinto efiselekayo ukuba omabonakude kanye diopter ukulungiswa.

Yini enye kubalulekile

Nokho, abanye, hhayi izici ngakho lembulunga yonke elinezinto ezinhlobonhlobo omabonakude, badlala indima ebalulekile ngokukhetha. Ukujula Kokuhlakanipha ensimini libizwa ukubaluleka ingxenye ukuba into observation, okuyinto ayidingekile kabusha izinto eziza kuqala ubukele. Kuyinto ephansi, kulapho the kaningi idivayisi.

Izingilazi zokubuka stereoscopic (Binocular) isici esingokwemvelo esweni sici womuntu, okuyinto wenza sikwazi ukuba zibone izinto ngesibalo nangohlobo eside. Lokhu ngokunenzuzo ngaphambi noma monocular isibonakude. Kodwa siyimfanelo kuwusizo emkhakheni, kuphazamise kwezinye izimo. Ngakho-ke, isibonelo, kule izibuko opera lincishisiwe.

Ngokusho kohlelo optical lens omabonakude kukhona (yaseshashalazini, ungowaseGalile) kanye prismatic (noma ensimini). Esikhathini sokuqala - a beso ratio ezinhle, isithombe bukhoma, khona nje ukwenyuka kancane, futhi insimu ewumngcingo umbono. Okwesibili, asetshenziselwa neendulungu, ukuguqulela isithombe nabokhulumile eyatholakala kusukela lens e evamile. Lokhu kunciphisa ubude Binocular wokubuka engela iyakhula.

Transparency isici sibizwa ngokuthi idivayisi ikhono ukudlula imisebe yokukhanya uzwakalise ingxenyenamba. Isibonelo, uma u-40% ukulahlekelwa ukukhanya, lo Coefficient ilingana 0.6. Inani layo esiphezulu - iyunithi.

Kangakanani umzimba omabonakude

Inzuzo yayo eyinhloko - amandla. izinga Shockproof izindlu rubberised inikezwa, ngokusebenzisa ibuye lokuzuziwe nokwethenjelwa ngenkathi ugcina izandla futhi umswakama ukumelana in sezulu zinomswakama.

omabonakude Modern waterproof zivaliwe ukuze kungase kube isikhathi esithile ngaphansi kwamanzi kuya 5 amamitha ukujula ngaphandle ukulimala uqobo. I lens ukuvikela kusuka fogging, ugcwalisa isikhala esiphakathi kwawo ngenhlabathi nitrogen. Lezi zimfanelo zibalulekile ukuze intaba, abazingeli, izazi zemvelo. Rangefinder omabonakude kanye umcwaningi Ukugunda, kudivayisi ukucasha nge kwe-matte - abalandeli ukubukela izilwane.

Ezinye izici ze-non-standard amadivayisi ngabanye ezifana isimame isithombe, i-laser uhla othole noma ikhampasi esakhelwe kakhulu izindleko kanye omabonakude wamukelekile kuphela uma kunesidingo. Nquma ngokwakho - ngabe udinga ezifana omabonakude rangefinder uma bazimisele ukukhokhela esingeziwe le ndlela.
