Kungakhathaliseki ukuthi ufuna ama-landscape shots, izithombe ezisuka kumdlalo wamuva wezemidlalo noma izithombe ezitaladini, kunezinhlobo eziningi zokukhetha ezinikeza ukulawula okuningi kunokwama-kit lens standard. Ukubamba isithombe esiphelele akulula, kodwa, ngenhlanhla, ukukhetha kahle kwe-lens kungenza izithombe zakho zibe nemfanelo engcono. Futhi ezinye ze-Nikon lens ezingcono kakhulu aziveli ngisho nakule minyaka eyishumi. Nakuba kungase kukumangaze ukubona lens lapha eye emakethe iminyaka, kungubufakazi nje ukuthi Nikon lens ukuma ukuhlolwa kwesikhathi futhi uqhubeke ukunikeza izithombe evelele. Udinga usizo oluhlaselwa phansi kwe-lens engcono kakhulu? Lolu hlu luzokusiza ukuthi uthole okuqinisekisiwe ukuphakamisa umdlalo wakho wezithombe.
Ngokusebenza kahle kokusebenza kwe-optical, i-Tamron AF 70-300mm F / 4.0-5.6 lens iyisinqumo esiyingqayizivele kwabanikazi be-Nikon DSLR abafuna ukuhlanganiswa okukhulu kokusondeza nokubaluleka. I-motor eyakhelwe kuyo kusiza ukusebenzisa ngokushesha ukuzethemba okuzenzekelayo kwe-Tamron ultrasonic eyenzelwe ngokuqondile ukuthatha isinyathelo esisheshayo esithinta imidlalo noma ukugijima. Uma umthwebuli wezithombe ekhetha ukuhlehlisa noma ukwenza ukulungiswa kwesithombe ngesikhala, ukugxila kwesikhombisi sesikhathi esigcwele kuhlanganiswe ngaphandle kwesidingo sokushintsha noma izinkinobho. Ukusondeza i-Tamron lens yenza okungcono kakhulu phakathi kwe-180mm no-300mm, okuphawulwe ngendwangu ngendwangu yegolide yokuma okusheshayo. Ukushintsha emzimbeni we-lens kushintshela kalula kwimodi ye-Macro, ukuvumela ukugxila kwebala eliseduze kwendaba enendawo enhle yebanga elingamamitha amathathu.
Idizayinelwe ukuba ibe yinkimbinkimbi futhi engaqondakali, ithegi yentengo yebhajethi ye-Nikon AF-S DX Nikkor 35mm f / 1.8G lens ayisho imiphumela yesabelomali. Ngokuphambene nalokhu, inketho yokuqala-friendly iyisisombululo esiphelele sokudubula okuphansi, kanye nokuthatha izithombe, izithombe noma izizinda ezififikile. Ubude obude be-35mm bukhulu ngokudala i-angle yokubuka "yemvelo," ngakho-ke izithombe zizobukeka ngendlela obuka ngayo. Ukufakwa kwef / 1.8G kwenezela ukulawula okujulile okujulile kokuzulazula izihloko, okuvumela imiphumela emihle kakhulu ye-portrait, kanye nokusebenza okuphansi okuvelele. I-Nikkor's wave wave motor iyasiza ukugxila ngokuzenzakalela kusebenze ngokungabonakali ukutholakala okuzwakalayo. Phakathi naleso sikhathi, imodi ye-Macro yenza i-lens ikwazi ukusondelana njengonyawo olulodwa esihlokweni ngaphandle kokufiphaza.
Njengomunye wama-lens wokuqala angama-angeli okuqala ukunikeza ukukhanya okukhulu, i-Sigma 10-20mm f / 3.5 iyisinqumo esihle kubathwebuli bezithombe abafuna isisombululo esikhulu se-Nikon DSLR. Ekhiqizwe ngokuxubana kwensimbi nesipulasitiki, i-Sigma inhle kakhulu ngokudlala izithombe eziphansi. Ku-photographer othanda ukulawula ukujula kwensimu, ukuvula okusheshayo kwe-Sigma kuvumela ukulawula okuqondile. Ukufakwa kwezingubo eziphezulu kakhulu kusiza ukunciphisa ama-flare noma ukuphefumula, kuyilapho uhlelo lokugxila ngaphakathi lungcono kakhulu ekusetshenzisweni kwezihlungi zokwehlisa. Ekugcineni, ikhamera ikhanya ngempela lapho idubula i-landscape izithombe, ukwakha ngaphakathi, imishado, isibhamu seqembu noma ngisho nezakhiwo. Uhlelo lokugxila ngokwalo luyithuli elihle, lwenza kahle kakhulu ngentengo futhi lihlanganisa kakhulu esitolo esikhulu se-agent ye-real estate
I-Nikon AF-S i-DX Micro Nikkor 85mm f / 3.5G lensi ivumela isithombe esisekelwe ngesandla ngokuhamba ngesivinini se-shutter esincane kunamanye amalensi okuncintisana. Ekugcineni, lokhu kuholela ezithombeni ezibukhali nokunciphisa kwe-chromatic aberration. Ukukhuliswa okungu-1: 1 kuvumela izinto ukuthi zihlolwe ubukhulu bompilo esithombeni sesithombe se-lens kude namasentimitha angu-11.2 kuphela. Ukufakwa kwesistimu yokuqiniswa kwe-optical kuhamba phambili ekusizeni isibhamu esicacile se-macro. I-lens ingaba kabili njenge-telephoto prime lens encane uma udinga ukushintsha amagiya futhi usebenze ngezihloko ezingekho macro.
Uma inhliziyo yakho isethwe ekutholeni konke okusemandleni, ungabhekanga ngaphezu kwe-Nikon AF-S FX Nikkor 50mm f / 1.8G. Efaka ubude obude be-50mm, lolu lensuku lwe-star lensuku lokudubula lunikeza ibanga elincane lama-1.48 amamitha. Njenge-lens yansuku zonke, i-50mm yenza i-lens enkulu eningi-nxazonke, futhi iyahamba kahle (itinganisa ama-ola angu-6.6 kuphela). Futhi naphezu kokuba ngaphezulu kwesabelomali, i-50mm ayikhiphi ikhwalithi yokwakha (isisindo sezulu-uphawu olusindile lens ivimbela noma yikuphi ukutholakala komswakama noma uthuli).
Ukuze uthole imali, i-50mm inikeza izithombe ezibukhali ngokucacile kulo lonke uhlaka lwesithombe. Imibala iyalinganisela kahle, futhi amathoni esikhumba aphuma eqinisweni kwifomu futhi imodi ye-bokeh inikeza ukujula okukhulu kokulawulwa kwensimu. Ukusondeza kwe-autofocus kuyashesha ngokwanele ukuzitholela kusihloko esisheshayo, ngakho-ke ungakwazi ukubala ukukhawulela kokuqapha kokuqapha. Kukhishwe ngoJuni ka-2011, i-50mm isimile isikhathi sokuhlolwa (nokukhishwa okusha okwedlule) futhi ukusekela lo mqondo kuyinkani ukungazinaki 4.8 ku-5 isilinganiso se-Amazon ngamaphesenti angu-89 ukubuyekezwa kwezinkanyezi ezinhlanu.
Ukuhleleka kwe-telephoto zoom kanye nenani elifanele lokusiza kwenza i Nikon AF-S DX Nikkor 55-300mm f / 4.5-5.6G ED yokunciphisa ukuvivinywa kwamalensi isinqumo esihle semvelo nemidlalo yezithombe. Ngokwebukeka konke, ukubukeka kuka-55-300mm futhi uzizwa sengathi kunanoma yimuphi omunye i-Nikon DX lens nge-casing black plastic kanye namasongo okusondeza. Kodwa uma kuziwa ekusebenzeni, lokho okushiwo ngu-55-300mm okuntuleka kokuvula nokuzenzakalela kwe-autofocus, kwenzelwa izinga eliphezulu lesithombe. Lapho ukukhanya kwe-55-300mm kuyinani lentengo yokusebenza, ngakho-ke ungalindela izithombe ezinhle ezithatha izithombe ezise-safari noma ezingasendlini yakho.
Isithombe sokukhanya okuphansi asikwenzi nje ebusuku. Kungenzeka, mhlawumbe, ukudubula ngaphakathi endlini ngaphandle kokukhanya okuncane, noma ngisho nokuma emthunzini ongaphandle. Noma yikuphi, ukuze uthole ukudubula okuhle kunazo zonke kuzilungiselelo ezikhanyayo eziphansi, uzodinga i-lens esheshayo. Ngokungangabazeki, lokho kubaluleke nakakhulu kunokuba nekhamera engaduduza ngokuhlanzekile kuma-ISO aphezulu. Amalensi amaningi okusondeza ama-lens ajikeleza f / 3.5-f / 5.6 ukuvula okukhulu, kodwa ukukhuphuka okuphezulu kunakho konke (funda: ephansi inombolo ye-f), ngokushesha i-lens ikhona. Le-lens prime lens inevula enkulu ye f / 1.8, okwenza kube ngesivinini esikhulu futhi ngaleyo ndlela inkulu yokubamba izithombe ngokukhanya okuphansi. Ngaphandle kwalokhu, inebude obugxile obuyi-85mm nobubanzi obuncane bokugxila kwe-.80m. Inekhwalithi yokwakha eqinile futhi ngenkathi singasincoma ukuyiyeka, abanye ababuyekezi e-Amazon bayavuma ukwenza kanjalo futhi bayilungisa ngaphandle kokuqala.
Umehluko phakathi kwesithombe esithathwe ngemodi ye-Portrait ye-iPhone eyithuthukisiwe kanye nenye ethathwe nge-lens professional portrait kwi-DSLR yilokho uMark Twain abiza khona ngokuthi "umehluko phakathi kwesibani sombane nombane." Ukuze uthole isithombe esihle kakhulu se-portrait, Uzofuna ilensi esheshayo. Futhi nakuba i-af / 5.6 ingase ingakhulumi kuze kube manje kusuka ku-af / 1.4, ukuvula okubanzi kungalimaza imininingwane yangemuva ngokuphumelelayo ukuze kugxilwe kulo mbandela, isici esifise ukubizwa ngokuthi i-bokeh. Leli lensi ye-Nikon ayithengi kodwa engenazikhathi eziphezulu f / 1.4 kanye nobude obugxile obuyi-85mm, yenza i-portrait ephelele yokudubula. Eqinisweni, uNikon uthi ubude obubekwe ngu-85mm buhle kakhulu kumsebenzi we-portrait usebenzisa ikhamera ye-SLR engu-35mm. Ihlumela kahle ezimweni eziphansi, futhi ikhuthaza ababuyekezi abaningana bama-Amazon ukuthi bayibambe ngokuthi i-lens engcono kakhulu abaye baba nayo.
