ໂຟກັສດ້ວຍມື:

1. ເບິ່ງຜ່ານກ້ອງຖ່າຍຮູບຂອງທ່ານ viewຜູ້ຊອກຫາ.
2. Rotate the focus ring on the lens until your subject appears sharp and clear in the viewfinder's rangefinder patch.
3. The distance scale on the lens indicates the current focus distance.

ການຄວບຄຸມ Aperture:

1. Rotate the aperture ring to select your desired f-stop.
2. Smaller f-numbers (e.g., f/2.8) indicate a wider aperture, allowing more light and creating a shallower depth of field.
3. Larger f-numbers (e.g., f/22) indicate a narrower aperture, allowing less light and creating a greater depth of field.

ຄວາມເລິກຂອງພາກສະຫນາມ:

The depth of field scale on the lens can be used to estimate the range of acceptable sharpness at a given aperture and focus distance. Align the focus distance with the desired aperture markings on the scale to see the near and far limits of focus.
