Panasonic Lumix G 20mm F/1.7 Asph I Vs Ii: The Battle Of The Primes
What To Know
- 7 ASPH I and II lenses share a common focal length and maximum aperture, suggesting similar image quality at a glance.
- On the other hand, the II version adopts a predominantly plastic construction, with a metal lens mount.
- The I version employs a contrast-detection autofocus system, which relies on the camera’s sensor to determine focus.
In the realm of Micro Four Thirds photography, the Panasonic Lumix G 20mm f/1.7 ASPH lens stands as a versatile and popular choice for photographers seeking a compact, high-quality prime lens. With two iterations available—the original I and the subsequent II version—photographers are often faced with the dilemma of choosing between these two lenses. This comprehensive comparison delves into the key differences between the Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses, providing valuable insights to help you make an informed decision.
Image Quality: A Clash of Resolution and Bokeh
The Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses share a common focal length and maximum aperture, suggesting similar image quality at a glance. However, closer inspection reveals subtle differences in their optical performance.
The first-generation Lumix G 20mm f/1.7 ASPH I lens delivers sharp and detailed images, particularly in the center of the frame. However, it exhibits noticeable softness and chromatic aberration towards the edges, especially when shooting wide open at f/1.7.
In contrast, the second-generation Lumix G 20mm f/1.7 ASPH II lens demonstrates improved optical performance across the entire frame. It resolves finer details with greater consistency, even at the edges, thanks to its updated optical design. Additionally, the II version exhibits reduced chromatic aberration, resulting in cleaner and more accurate colors.
When it comes to bokeh, both lenses produce pleasing background blur, with the II version offering slightly smoother and more circular bokeh highlights. This is attributed to its improved optical formula and more rounded aperture blades.
Build Quality: A Tale of Metal and Plastic
The Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses differ significantly in their build quality. The I version features a durable metal construction that exudes a sense of solidity and reliability. It also incorporates a metal lens mount, ensuring a secure connection to the camera body.
On the other hand, the II version adopts a predominantly plastic construction, with a metal lens mount. While it retains a solid feel, it may not inspire the same confidence as the all-metal design of its predecessor. The use of plastic may also raise concerns about long-term durability, although Panasonic claims that the lens is weather-sealed and splash-resistant.
Autofocus Performance: A Question of Speed and Accuracy
The Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses utilize different autofocus systems, resulting in varying performance.
The I version employs a contrast-detection autofocus system, which relies on the camera’s sensor to determine focus. While it performs adequately in good lighting conditions, it can struggle in low-light situations or when tracking moving subjects.
The II version, on the other hand, features a hybrid autofocus system that combines contrast detection with depth-from-defocus technology. This allows for faster and more accurate focusing, even in challenging lighting conditions. The II version also incorporates a stepping motor, which operates quietly and smoothly, making it ideal for video recording.
Handling and Ergonomics: A Matter of Personal Preference
The Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses exhibit similar handling and ergonomics, with a few minor differences.
Both lenses feature a compact and lightweight design, making them easy to carry and use throughout the day. They also share a common filter thread size of 46mm, allowing for easy attachment of filters or lens hoods.
However, the II version incorporates a dedicated focus ring with a more pronounced texture, providing a better tactile experience when manually focusing. Additionally, the II version features a customizable function button that can be programmed to perform various tasks, such as activating autofocus or adjusting exposure settings.
Price and Availability: A Question of Value
The Panasonic Lumix G 20mm f/1.7 ASPH I lens is typically available at a lower price point compared to the II version. This makes it a more affordable option for budget-conscious photographers. However, it is important to consider the trade-offs in image quality, build quality, autofocus performance, and handling when making a purchasing decision.
The Panasonic Lumix G 20mm f/1.7 ASPH II lens commands a higher price, but it offers noticeable improvements in image quality, build quality, autofocus performance, and handling. Whether the additional cost is justified depends on the individual photographer’s needs and budget.
Which Lens is Right for You? A Decision Based on Your Needs
The choice between the Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses ultimately depends on your specific requirements and preferences.
If you prioritize image quality, build quality, autofocus performance, and handling, and are willing to pay a premium for these features, the II version is the better choice. It delivers superior optical performance, a more durable construction, faster and more accurate autofocus, and improved ergonomics.
However, if you are on a tighter budget and prioritize affordability, the I version may be a more suitable option. While it may not offer the same level of performance as the II version, it still produces good image quality and is a capable lens for everyday photography.
Beyond the Comparison: Additional Considerations for Your Decision
In addition to the direct comparison between the Panasonic Lumix G 20mm f/1.7 ASPH I and II lenses, there are a few additional factors to consider when making your purchase decision:
- System Compatibility: Ensure that the chosen lens is compatible with your Micro Four Thirds camera.
- Intended Use: Consider the primary purpose of the lens. If you need a lens for low-light photography or videography, the II version’s improved autofocus performance may be beneficial.
- Personal Preferences: Evaluate your personal preferences for image quality, build quality, handling, and budget. Choose the lens that best aligns with your photographic style and needs.
