+ | The Evetar [[m12_5.4mm_f2.0|M12 5.4mm f2.0 lens]] is a low distortion 10MP lens. This produces a sharp high resolution image with a relatively good DOF - depth of field. | ||
+ | The Evetar [[m12_5.5mm_f1.8|M12 5.5mm f1.8 lens]] is a low distortion MP lens. | ||
+ | |||
+ | //f// or //f-stop// represents the size of the aperture - the amount of the light entering the lens. The higher the //f-stop// the more light. | ||
+ | |||
+ | There is an inverse correlation between the //f-stop// and the DOF. The higher the //f-stop// the shallower the DOF. | ||
+ | |||
+ | For the SUB2r 4K/1080p camera board we selected the [[m12_5.4mm_f2.0|5.4mm f2.0]] for it's exceptional image quality. | ||
+ | |||
+ | The optional [[m12_5.5mm_f1.8|M12 5.5mm f1.8 lens]] collects and delivers 23.4% more light to the image sensor than the [[m12_5.4mm_f2.0|f2.0]]. | ||

+ | Picking the right lens for your application is key to an exceptional video image. | ||
