Ungayikhetha njani ireyithi yomzimba efanelekileyo ye-lensed ands?

Ukukhetha umlinganiso we-arber of theI-lens yemvelisoIfuna ukuthathela ingqalelo izinto ezininzi, ezinjengeemfuno ezithile zesicelo, iimfuno zokuchaneka kweMilinganiselo, uhlahlo-lwabiwo mali lweendleko, njl njl.

1.Chonga iimfuno zesicelo

Chonga iimfuno ezithile zezicelo zemizi-mveliso yomgangatho womfanekiso kunye nokulinganisa ukulinganisa, kunye nokumisela imigangatho efunekayo yomgangatho esekwe kwiimfuno. Umzekelo, kwezinye iinkqubo ezifuna ukucaciswa komfanekiso okuphezulu kunye nokuchaneka, kunokuba yimfuneko ukukhetha i-lens yemveliso enemigangatho esezantsi yokufakelwa.

2.Ukuqondaaumsindotypes

Qonda ifuthe lamanqanaba ahlukeneyo omgangatho kumgangatho womfanekiso, kubandakanya ukugqwetha, i-chromamatic ye-herherte, indawo esasazwayo, njl njl.

I-abeberes ihlulekile ikakhulu ibe yi-radial eeracial kunye neengcingo ze-range. I-radial eeradion ihlala iphawulwa yi-distortion yento emphethweni womfanekiso, ngelixa i-ablestoras ye-tange ibekwe ziimpazamo eziphakathi kwelensi kunye neplanethi ejongelayo. Kwizicelo ezininzi zemizi-mveliso, i-radralicals mhlawumbi yeyona ngxaki iphambili.

3.Jonga imigaqo-nkqubo ye-lens

NiniUkukhetha ilensi, kuyacetyiswa ukukhangela idatha ye-aberhermenti ye-abreber kwinkcazo yayo, edla ngokunikwa njengepesenti okanye ixabiso le-pixel. Ngezicelo ezifuna umlinganiso ococekileyo wokuchaneka, zinokufaneleka ukukhetha iilensi ezinemigangatho esezantsi yokufakelwa.

4.Ukuqonda indlela yokuvavanya

Abavelisi beelensi badla ngokubonelela ngedatha okanye iindlela zovavanyo lwe-carling. Ukuqonda ezi ndlela zovavanyo kunokunceda kuvavanye ngokuchanekileyo ukusebenza kwe-anling yelensi.

5.Cinga ngohlahlo-lwabiwo mali

Ngokubanzi, iilensi zokusebenza ezinemizi-mveliso ezinemilinganiselo esezantsi yokufakelwa iyabiza kakhulu. Ke ngoko, kuyimfuneko ukuqwalasela uhlahlo-lwabiwo mali lweendleko ukufumanisa ukuba ifuneka ilensi ephezulu.

6.Qwalasela iimeko zokusingqongileyo

Kuyimfuneko ukuqwalasela izinto ezinje ngeemeko zokukhanyisa kunye nobushushu obutshintsha kwindawo yokusebenza yokuqinisekisa uzinzo kunye nokuthembeka kwelensi.

Ukongeza kwinqanaba le-aberling, iUkukhetha ilensiKananjalo kufuneka ziqwalasele ukuba ngaba ezinye iiparamitha ezinjengokusonjululwa, indawo yokujonga, ubude begxile, njl njl. Dibanisa iimfuno.

Iingcinga zokugqibela:

Ukuba unomdla wokuthenga iintlobo ezahlukeneyo zeelensi zokujonga, ukuskena, iidrones, ikhaya, okanye naluphi na olunye usetyenziso, sinayo into oyifunayo. Nxibelelana nathi namhlanje ukuze ufunde ngakumbi malunga neelensi zethu kunye nezinye izinto.
