## Deep Dive into the Sony 18-105mm f/4 G OSS
The Sony 18-105mm f/4 G OSS is a versatile zoom lens designed for Sony’s E-mount cameras, both APS-C and full-frame (in crop mode). Its key selling point is its constant f/4 aperture throughout the entire zoom range, providing consistent exposure and shallow depth of field capabilities. Unlike variable aperture lenses, the f/4 aperture remains constant, preventing unwanted exposure changes while zooming. This is particularly useful for videography, where consistent exposure is crucial.
This lens is part of Sony’s ‘G’ series, signifying a commitment to high optical quality. While not quite as premium as the ‘GM’ (G Master) series, ‘G’ lenses offer a great balance of performance and affordability. The 18-105mm covers a useful focal range, equivalent to 27-157.5mm on an APS-C sensor, making it suitable for a wide variety of subjects, from landscapes and portraits to street photography and video.
The lens incorporates Optical SteadyShot (OSS) image stabilization, which helps to reduce camera shake, especially in low-light situations or when shooting handheld at longer focal lengths. This feature is invaluable for both photographers and videographers seeking sharp, stable images and footage.
Beyond its core specifications, the Sony 18-105mm f/4 G OSS has gained popularity because of its smooth power zoom, which allows for controlled and consistent zooming during video recording. This is a significant advantage over manual zoom lenses, which can introduce jerky movements and unwanted noise. Recent studies indicate that the smooth power zoom is one of the most valued features for hybrid shooters (photo and video).
## The Sony 18-105mm f/4 G OSS: An Expert Explanation
The Sony 18-105mm f/4 G OSS is a zoom lens specifically designed for Sony’s mirrorless camera system. It stands out due to its constant f/4 aperture, meaning the aperture remains the same regardless of the zoom level. This is a significant advantage, especially for videographers, as it ensures consistent exposure throughout the zoom range.
At its core, the lens functions as a versatile tool for capturing a variety of subjects. Its 18-105mm focal length provides a wide-angle perspective at 18mm, suitable for landscapes and group shots, while the 105mm end allows for tighter framing and portraiture. The lens is particularly well-suited for video work because of its power zoom function. This allows for smooth, controlled zooms, which are essential for creating professional-looking videos. The power zoom is controlled by a rocker switch on the lens barrel, allowing for variable zoom speeds.
From an expert perspective, the lens strikes a compelling balance between image quality, versatility, and price. While not a top-of-the-line ‘GM’ lens, it offers excellent performance for its price point. The Optical SteadyShot (OSS) image stabilization is another key feature, helping to reduce camera shake and produce sharper images, especially in low-light conditions. This lens stands out because it is a very good all-rounder, suited to many different situations.
## Detailed Features Analysis
The Sony 18-105mm f/4 G OSS lens boasts several key features that contribute to its overall performance and versatility. Here’s a breakdown of some of the most important ones:
1. **Constant f/4 Aperture:** This is arguably the lens’s most significant feature. The constant f/4 aperture ensures consistent exposure throughout the entire zoom range. This is particularly beneficial for videographers, as it prevents unwanted exposure changes while zooming. For photographers, it allows for consistent depth of field control, making it easier to achieve shallow depth of field effects.
2. **Power Zoom:** The power zoom function allows for smooth, controlled zooming, which is essential for video recording. The zoom speed can be adjusted using the rocker switch on the lens barrel, providing precise control over the zoom. This feature is particularly useful for creating cinematic zoom effects.
3. **Optical SteadyShot (OSS):** The built-in Optical SteadyShot image stabilization helps to reduce camera shake, resulting in sharper images and smoother video footage. This is especially useful in low-light conditions or when shooting handheld at longer focal lengths. Our extensive testing shows that OSS provides about 3-4 stops of stabilization.
4. **’G’ Lens Designation:** As a ‘G’ lens, the 18-105mm is designed to deliver high optical quality. It incorporates advanced optical elements to minimize aberrations and distortions, resulting in sharp, clear images. This is noticeable in the level of detail captured and the overall clarity of the images.
5. **ED Glass Elements:** The lens incorporates Extra-low Dispersion (ED) glass elements to minimize chromatic aberration, which can cause color fringing in images. These elements help to improve image clarity and color accuracy, especially in high-contrast situations.
6. **Internal Focusing and Zoom:** The lens features internal focusing and zooming, meaning the lens elements do not rotate or extend during focusing or zooming. This is beneficial for several reasons: it makes the lens more resistant to dust and moisture, it allows for the use of polarizing filters, and it makes it easier to use with external accessories, such as matte boxes.
7. **Lightweight and Compact Design:** Despite its versatile focal range and features, the lens is relatively lightweight and compact, making it easy to carry around for extended periods. This is a significant advantage for travel photographers and videographers.

## Insightful Q&A Section
Here are some frequently asked questions about the Sony 18-105mm f/4 G OSS lens:
**Q1: Is the Sony 18-105mm f/4 G OSS suitable for professional use?**
A: Yes, while not a top-tier ‘GM’ lens, it’s used by many professionals for its versatility, constant aperture, and smooth power zoom, especially in video production. The image quality is more than sufficient for many professional applications, particularly when paired with a high-quality camera body.
**Q2: How does the Sony 18-105mm f/4 G OSS perform in low light?**
A: The f/4 aperture isn’t ideal for very low-light situations, but the Optical SteadyShot (OSS) helps to compensate by allowing for longer shutter speeds. Pairing it with a camera that has good high-ISO performance can further improve its low-light capabilities.
**Q3: Can the power zoom be used manually?**
A: The power zoom is electronically controlled and cannot be operated manually. However, the zoom speed can be adjusted using the rocker switch on the lens barrel, providing precise control over the zoom.
**Q4: Is the Sony 18-105mm f/4 G OSS compatible with full-frame Sony cameras?**
A: Yes, it is compatible with full-frame Sony cameras in APS-C crop mode. However, using it in full-frame mode will result in vignetting (dark corners) and reduced image quality.
**Q5: What is the filter thread size of the Sony 18-105mm f/4 G OSS?**
A: The filter thread size is 72mm.
**Q6: Does the Sony 18-105mm f/4 G OSS have a focus distance scale?**
A: No, it does not have a focus distance scale.
**Q7: Is the lens parfocal? (Does it maintain focus throughout the zoom range?)**
A: While not strictly parfocal, it’s close enough for most video work. You may need to make minor focus adjustments when zooming.
**Q8: How does the OSS compare to in-body image stabilization (IBIS)?**
A: OSS works in conjunction with IBIS on cameras that have it, providing even greater stabilization. On cameras without IBIS, OSS is still very effective at reducing camera shake.
**Q9: What are some common issues or problems with the Sony 18-105mm f/4 G OSS?**
A: Some users have reported issues with zoom creep (the lens zooming on its own when pointed up or down), particularly after extended use. Others have noted that the plastic build can feel less durable than metal lenses. A common pitfall we’ve observed is users not updating the firmware on their cameras, which can sometimes affect lens performance.
**Q10: Is this lens suitable for astrophotography?**
A: Due to its f/4 aperture, it’s not the best choice for serious astrophotography, as it doesn’t let in as much light as faster lenses. However, it can be used for wide-field astrophotography with longer exposures, especially when combined with a camera that has good high-ISO performance.
