In contrast, the VILTROX 20mm f2.8 FE is a compact prime lens designed for expansive shooting with a fast autofocus system. This comparison will explore their features, usability, and overall value for photographers looking to enhance their gear.
Price Comparison
The Sony FE 1.4x Teleconverter is priced at $598.00, while the VILTROX 20mm f2.8 FE is significantly more affordable at $176.00. This means that the VILTROX lens is about 71% cheaper than the Sony teleconverter. For photographers on a budget or those seeking to invest in a quality wide-angle lens without breaking the bank, the VILTROX lens presents a compelling choice. However, the higher price of the Sony teleconverter reflects its specialized function and premium build quality.
Optical Performance
The optical performance of the Sony FE 1.4x Teleconverter is remarkable, as it retains full G Master performance and employs an aspherical lens element. This ensures that the quality of images remains high, even with a 1.4x focal length extension. The VILTROX 20mm f2.8 FE, with its optical structure of 10 elements in 8 groups, including 2 ED lenses and 2 aspherical lenses, promises crisp and clear shots. While both products offer excellent optical quality, the Sony teleconverter shines in scenarios requiring longer focal lengths, whereas the VILTROX excels in wide-angle photography.
Usability and Portability
The VILTROX 20mm f2.8 FE stands out for its portability, weighing only 157g, making it ideal for impromptu shoots in diverse environments. Its compact design is a significant advantage for photographers who prioritize mobility. In contrast, the Sony FE 1.4x Teleconverter, while not excessively heavy, is designed to be used with specific lenses like the SEL70200GM and SEL100400GM, which may add bulk to your setup. For users who frequently change locations or prefer a lightweight kit, the VILTROX lens is a more convenient option.
Autofocus and Shooting Experience
When it comes to autofocus capabilities, the VILTROX 20mm f2.8 FE offers fast autofocusing performance, which is essential for capturing fast-moving subjects. It also supports EXIF information transmission and features a near-silent shutter sound, enhancing the shooting experience. The Sony FE 1.4x Teleconverter does not compromise autofocus performance when used with compatible lenses, ensuring that autofocus remains effective even after the focal length is extended. However, the VILTROX's silent operation may appeal more to those shooting in quiet environments or during events.
Design and Build Quality
The build quality of the Sony FE 1.4x Teleconverter is robust, featuring a dust and moisture-resistant design that supports outdoor shooting in challenging conditions. This durability adds value for wildlife and sports photographers who require reliable equipment. The VILTROX 20mm f2.8 FE, while portable, does not emphasize weather resistance in its features, which may be a consideration for photographers working in varying weather conditions. Overall, the Sony teleconverter provides superior resilience, making it a better option for rugged environments.
Compatibility and Versatility
The Sony FE 1.4x Teleconverter is compatible with select Sony lenses, which may limit its versatility to those already invested in the brand’s ecosystem. However, it significantly enhances the capabilities of compatible lenses, making it a powerful tool for specific photography needs. On the other hand, the VILTROX 20mm f2.8 FE is designed for a wide range of Sony e-mount cameras, including models like the a7 series and a6000 series, offering greater versatility for various photography styles. This makes the VILTROX lens a more universal choice for photographers looking to expand their creative options.
Which should you buy?
Choosing between the Sony FE 1.4x Teleconverter and the VILTROX 20mm f2.8 FE ultimately depends on your photography needs and budget. The Sony teleconverter is ideal for those focused on sports and wildlife photography who require extended reach without sacrificing image quality. However, at $176.00, the VILTROX lens offers exceptional value, portability, and versatility for casual photographers or those seeking a reliable wide-angle option. If budget and mobility are your priorities, the VILTROX is the clear winner. Conversely, if you require the specialized capabilities of a teleconverter, the Sony option will serve you well.
