தயாரிப்பு முடிந்துவிட்டதுview

The Sigma 24mm f/1.4 DG HSM Art Lens is part of Sigma's Global Vision Art line, known for its sophisticated optical design and high-level performance. Key features include:

• Large Aperture: A bright f/1.4 maximum aperture excels in low-light conditions and provides extensive control over depth of field.
• Advanced Optical Design: Incorporates FLD and SLD glass elements to minimize chromatic aberrations and distortions, ensuring high sharpness and clarity.
• Hyper Sonic Motor (HSM): Provides fast, quiet, and accurate autofocus performance.
• Super Multi-Layer Coating: Reduces flare and ghosting for improved contrast and color fidelity.
• குறைந்தபட்ச கவனம் தூரம்: Capable of focusing as close as 7.1 inches (18 cm) for dynamic close-up shots.

அமைவு

உங்கள் கேமராவுடன் லென்ஸை இணைத்தல்

1. கேமரா மற்றும் லென்ஸ் இரண்டும் சுத்தமாகவும், தூசி இல்லாமல் இருப்பதையும் உறுதி செய்து கொள்ளுங்கள்.
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. Rotate the lens clockwise until it clicks securely into place. Do not force the lens.

லென்ஸைப் பிரித்தல்

1. While holding down the lens release button on your camera body, rotate the lens counter-clockwise until it stops.
2. கேமரா உடலில் இருந்து லென்ஸை கவனமாக அகற்றவும்.
3. Attach the front and rear lens caps to protect the glass elements.

லென்ஸை இயக்குதல்

ஃபோகஸ் பயன்முறை சுவிட்ச் (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 (ஆட்டோஃபோகஸ்): For automatic focusing. The Hyper Sonic Motor (HSM) provides fast and quiet operation.
• MF (கையேடு கவனம்): For manual focusing. Rotate the focus ring to adjust focus. This mode is often preferred for precise focusing in specialized applications like astrophotography.

துளை கட்டுப்பாடு

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 (கையேடு கவனம்).
• 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.

பராமரிப்பு

லென்ஸை சுத்தம் செய்தல்

• Use a soft, lint-free cloth or a lens brush to remove dust from the lens surface.
• For stubborn smudges, apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the lens in a circular motion.
• Never use abrasive materials or harsh chemicals.

சேமிப்பு

• லென்ஸ் பயன்பாட்டில் இல்லாதபோது எப்போதும் முன் மற்றும் பின் லென்ஸ் மூடிகளை இணைக்கவும்.
• லென்ஸை குளிர்ந்த, உலர்ந்த இடத்தில், நேரடி சூரிய ஒளி மற்றும் தீவிர வெப்பநிலையிலிருந்து விலகி சேமிக்கவும்.
• If storing for extended periods, consider using a dehumidifying agent to prevent mold growth.

சரிசெய்தல்

ஆட்டோஃபோகஸ் சிக்கல்கள்

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

• மென்பொருள் புதுப்பிப்பு: 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.
• கவனம் அளவுத்திருத்தம்: 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.
• லைட்டிங் நிலைமைகள்: Autofocus performance can be affected by very low light or subjects with low contrast. Switch to manual focus if necessary.

படத்தின் தரம் பற்றிய கவலைகள்

If images appear soft or lack expected sharpness:

• Check Focus: Ensure your subject is in sharp focus. In manual focus, verify using Live View உருப்பெருக்கம்.
• துளை: 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.
• கேமரா குலுக்கல்: Use a tripod or faster shutter speed to avoid blur from camera movement.
