The Sigma 105mm f/1.4-16 Standard Fixed Prime Camera Lens is engineered for outstanding wide-aperture, mid-telephoto performance. Featuring an impressive F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups, a design choice that is uncommonly large for a prime lens. This sophisticated optical system, which includes three FLD glass elements, two SLD glass elements, and one aspherical lens element, is designed to minimize axial chromatic aberration, delivering extremely high resolution and ample peripheral light volume.

6. Кыйынчылыктарды
Here are some common concerns and their potential solutions:
| Маселе | Мүмкүн болгон себеп / Чечим |
|---|---|
| Lens feels very heavy on camera body. | This lens is designed with a robust build and large optical elements, contributing to its weight. This is normal. Consider using a tripod or monopod for extended shooting sessions to reduce strain. |
| Minor dust particles visible on lens elements. | Small dust particles are common and rarely affect image quality. Use a blower brush for removal. If persistent, consult a professional lens cleaning service. |
| Autofocus is slow or inconsistent. | Ensure the AF/MF switch is set to AF. Check camera settings for focus mode (e.g., single-shot, continuous). In very low light, autofocus may struggle; consider manual focus or adding more light. |
