Sony SEL1635GM Specification

The Sony SEL1635GM, part of Sony's G Master series, is a versatile full-frame lens designed for professional photographers and videographers seeking superior optical performance. With a focal length range of 16-35mm, it offers a wide-angle perspective ideal for landscapes, architecture, and event photography. The lens features a maximum aperture of f/2.8, allowing for outstanding low-light performance and beautiful bokeh effects. Its optical construction includes 16 elements in 13 groups, incorporating advanced technologies such as two XA (extreme aspherical) elements and three aspherical elements to ensure extraordinary resolution and clarity across the entire frame. Additionally, two ED (Extra-low Dispersion) glass elements minimize chromatic aberrations, enhancing image quality.

The lens's Nano AR Coating reduces flare and ghosting, providing crisp, high-contrast images even in challenging lighting conditions. For autofocus, the SEL1635GM utilizes a Direct Drive SSM (Super Sonic wave Motor) system, offering fast, precise, and quiet operation, ideal for both stills and video. Its minimum focusing distance is 0.28 meters, and it provides a maximum magnification of 0.19x, allowing for dynamic close-up shots. The lens is dust and moisture-resistant, making it suitable for use in various environmental conditions. It has a compact and lightweight design, weighing approximately 680 grams, ensuring easy portability. The lens supports a 82mm filter thread, compatible with a wide range of filters. With its combination of advanced optics, durable construction, and professional-grade performance, the Sony SEL1635GM is a top choice for demanding users aiming to capture stunning, high-quality images and videos.

What should I do if my SEL1635GM lens is not focusing correctly?

If your SEL1635GM lens is not focusing correctly, first ensure that the lens and camera firmware are up to date. Check that the lens is properly mounted on the camera. If issues persist, clean the lens contacts and try shooting in different lighting conditions to rule out environmental factors.

Can I use my Sony SEL1635GM lens on a crop sensor camera?

Yes, you can use the Sony SEL1635GM lens on a crop sensor camera. However, the effective focal length will increase by a factor of 1.5x, which means the field of view will be equivalent to a 24-52.5mm lens on a full-frame camera.

What is the best way to clean the Sony SEL1635GM lens?

To clean your Sony SEL1635GM lens, use a soft, lint-free microfiber cloth. For stubborn smudges, you can lightly moisten the cloth with lens cleaning solution. Always clean in a circular motion from the center outward. Avoid using excessive force or abrasive materials.

How can I reduce lens flare when using the SEL1635GM?

To reduce lens flare with the SEL1635GM, use the lens hood provided, avoid shooting directly into bright light sources, and consider adjusting your shooting angle or position. Additionally, using a multi-coated UV filter can help minimize flare.

What are the recommended settings for astrophotography with the SEL1635GM?

For astrophotography with the SEL1635GM, use a tripod to stabilize your camera, set the aperture to f/2.8 for maximum light gathering, and adjust the ISO between 1600 and 3200. Use manual focus to achieve sharpness, and experiment with exposure times between 15-30 seconds to capture star detail.

Why is my SEL1635GM lens making a noise when focusing?

The SEL1635GM lens may produce some noise while focusing due to the operation of the autofocus motor. If the noise is excessive or unusual, ensure the lens firmware is updated. If the problem persists, consider having the lens serviced by a professional technician.

Is the Sony SEL1635GM lens weather-sealed?

Yes, the Sony SEL1635GM lens is weather-sealed, providing resistance against dust and moisture. This makes it suitable for use in challenging environmental conditions. However, it is still advisable to avoid extreme weather conditions to ensure longevity.

What is the minimum focusing distance of the SEL1635GM lens?

The minimum focusing distance of the Sony SEL1635GM lens is 0.28 meters (approximately 11 inches), allowing for relatively close-up photography at all focal lengths within its range.

How can I achieve the best sharpness with the SEL1635GM lens?

To achieve the best sharpness with the SEL1635GM lens, use a tripod to eliminate camera shake, stop down the aperture to f/5.6 or f/8 for increased depth of field, and use manual focus or focus peaking for precise focusing.
