설정

카메라에 렌즈 장착하기

1. 카메라와 렌즈 모두 깨끗하고 먼지가 없는지 확인하십시오.
2. Align the mounting index (red dot or white square) on the lens barrel with the corresponding index on your Canon EF mount camera body.
3. 렌즈가 제자리에 딸깍 소리가 나면서 단단히 고정될 때까지 시계 방향으로 돌리십시오. 렌즈를 억지로 돌리지 마십시오.

렌즈 분리

1. 카메라 본체의 렌즈 분리 버튼을 누른 상태에서 렌즈가 멈출 때까지 시계 반대 방향으로 돌립니다.
2. 카메라 본체에서 렌즈를 조심스럽게 분리하세요.
3. Attach the front and rear lens caps to protect the glass elements.

렌즈 작동

초점 모드 전환(AF/MF)

The lens features an AF/MF switch on its barrel. This switch allows you to select between autofocus (AF) and manual focus (MF) modes.

• AF(자동 초점): For automatic focusing. The Hyper Sonic Motor (HSM) provides fast and quiet operation.
• MF(수동 초점): For manual focusing. Rotate the focus ring to adjust focus. This mode is often preferred for precise focusing in specialized applications like astrophotography.

조리개 제어

The aperture (f/1.4 to f/16) is controlled via your camera body. A wider aperture (smaller f-number) allows more light into the lens, ideal for low-light photography and creating shallow depth of field with pleasing background blur (bokeh). A narrower aperture (larger f-number) increases depth of field, suitable for landscapes.

Astrophotography Considerations

This lens is highly regarded for astrophotography due to its wide 24mm focal length and fast f/1.4 aperture. When shooting stars or the Milky Way:

• Set the lens to MF (수동 초점).
• Focus to infinity. It is recommended to use your camera's Live View mode and zoom in on a bright star to achieve precise focus.
• Consider using a star tracker for longer exposures to prevent star trails.

유지

렌즈 청소

• Use a soft, lint-free cloth or a lens brush to remove dust from the lens surface.
• 잘 지워지지 않는 얼룩의 경우, 극세사 천에 소량의 렌즈 세척액을 묻혀 원을 그리듯 부드럽게 렌즈를 닦아주세요.
• 연마재나 강한 화학 물질을 사용하지 마십시오.

저장

• 렌즈를 사용하지 않을 때는 항상 앞면과 뒷면 렌즈 캡을 씌우십시오.
• 렌즈는 직사광선과 극한의 온도를 피해 서늘하고 건조한 곳에 보관하세요.
• 장기간 보관할 경우 곰팡이 발생을 방지하기 위해 제습제를 사용하는 것을 고려하십시오.

문제 해결

자동 초점 문제

If you experience inconsistent or inaccurate autofocus, consider the following:

• 펌웨어 업데이트 : Sigma periodically releases firmware updates to improve lens performance. It is highly recommended to keep your lens firmware up to date. This often requires the Sigma USB Dock (sold separately) and Sigma Optimization Pro software.
• 초점 보정: Some camera bodies allow for in-camera micro-adjustment of autofocus. If you have a Sigma USB Dock, you can perform more precise calibration for different focus distances.
• 조명 조건: Autofocus performance can be affected by very low light or subjects with low contrast. Switch to manual focus if necessary.

이미지 품질 문제

If images appear soft or lack expected sharpness:

• 집중력 점검: Ensure your subject is in sharp focus. In manual focus, verify using Live View 확대.
• 구멍: While the lens performs well wide open, stopping down by one or two stops (e.g., from f/1.4 to f/2.0 or f/2.8) can sometimes improve corner sharpness.
• 카메라 흔들림: Use a tripod or faster shutter speed to avoid blur from camera movement.
