Lub CS mount muaj qhov ntev ntawm qhov sib txawv ntawm lub lens thiab lub C mount, uas yog 17.526mm. Qhov no txhais tau tias cov lens CS mount siv tau rau cov koob yees duab C mount los ntawm kev siv lub C-CS mount adapter, tab sis cov lens C mount tsis tuaj yeem ntsia ncaj qha rau cov koob yees duab CS mount yam tsis muaj lub adapter vim qhov ntev ntawm lub lens thiab lub CS mount luv dua.
Lub CS mount muaj qhov deb ntawm qhov focal me dua li lub C mount, ua rau muaj qhov chaw ntau dua ntawm lub lens thiab lub sensor duab. Qhov chaw ntxiv no yog qhov tsim nyog los pab txhawb cov sensor duab me me uas siv hauv cov koob yees duab saib xyuas. Los ntawm kev txav lub lens deb ntawm lub sensor, CS mount lenses tau ua kom zoo rau cov sensor me me no thiab muab qhov ntev focal thiab kev npog tsim nyog.
Lub CS mount siv txoj hlua txuas, zoo ib yam li C mount, los txuas lub lens rau lub cev lub koob yees duab. Txawm li cas los xij, txoj hlua ntawm CS mount me dua li ntawm C mount, ntsuas 1/2 nti (12.5 hli). Qhov me me no yog lwm yam ntxwv uas sib txawv ntawm CS mount thiab C mount.
Cov tsom iav CS mount muaj ntau yam thiab tsim tshwj xeeb rau kev saib xyuas thiab kev ruaj ntseg.
