Price Comparison

When it comes to pricing, the VILTROX 56mm f/1.7 E Lens for Sony is significantly cheaper than the Sony FE 1.4x Teleconverter. The VILTROX lens is priced at $180.00, while the Sony teleconverter retails for $598.00. This makes the VILTROX lens about 70% less expensive than the Sony teleconverter, providing considerable savings for budget-conscious photographers. If cost is a primary factor in your decision-making, the VILTROX lens clearly emerges as the more economical choice.

Optical Performance

In terms of optical performance, both the Sony FE 1.4x Teleconverter and the VILTROX 56mm f/1.7 lens are designed to deliver high-quality images. The Sony teleconverter maintains full G Master performance and extends the focal length by 1.4x without compromising on image quality. It features an aspherical lens element and a dust and moisture resistant design, ideal for outdoor photography. Conversely, the VILTROX lens offers a full-frame equivalent focal length of about 85mm, which is particularly beneficial for portrait photography, thanks to its F1.7 aperture that provides a beautiful bokeh effect. Each product excels in its intended application, but the choice depends on whether you prioritize versatility or specialized portrait performance.

Compatibility

Compatibility is a crucial aspect when selecting camera accessories. The Sony FE 1.4x Teleconverter is specifically designed to work with compatible lenses such as the SEL70200GM and SEL100400GM, making it an excellent choice for users of these lenses who want to extend their range. On the other hand, the VILTROX 56mm f/1.7 lens is compatible with a range of Sony E-mount cameras, including the a7IV, a7RV, a6400, and a6700. If you own multiple lenses or cameras, the VILTROX offers broader compatibility, whereas the Sony teleconverter is more specialized.

Autofocus Capabilities

The autofocus performance of each product varies significantly. The VILTROX 56mm f/1.7 lens employs an STM silent motor, allowing for precise and fast autofocus, which is particularly beneficial for both novice and experienced photographers. This makes it a great option for capturing fleeting moments or fast-moving subjects. In contrast, the Sony FE 1.4x Teleconverter maintains the autofocus performance of the compatible lenses it is used with but does not provide autofocus capabilities of its own. If rapid and reliable autofocus is essential for your style of photography, the VILTROX lens has the advantage.

Weight and Portability

Weight and portability are important considerations for photographers on the go. The VILTROX lens is compact and lightweight at just 170 grams, making it easy to carry and ideal for travel or casual shooting. In contrast, while the exact weight of the Sony teleconverter is not provided, it is generally heavier due to its construction and intended use as an accessory that enhances existing lenses. For those who prioritize a lightweight setup, especially for extended shoots, the VILTROX lens is the clear winner.

Build Quality and Durability

In terms of build quality, the Sony FE 1.4x Teleconverter boasts a dust and moisture resistant design, ensuring reliability in various shooting conditions. This is particularly valuable for outdoor photographers who may encounter unpredictable weather. The VILTROX lens does not specify weather sealing but is designed for general use. If durability and resilience in challenging environments are top priorities for you, the Sony teleconverter stands out as a more robust option.

Intended Use

Both products cater to different photographic needs and preferences. The Sony FE 1.4x Teleconverter is primarily aimed at professional photographers looking to extend the range of their existing high-quality lenses without sacrificing image quality. This makes it particularly suitable for wildlife and sports photography. Conversely, the VILTROX 56mm f/1.7 lens is designed with portrait photographers in mind, offering a flattering perspective and excellent background separation. Your choice should reflect your photographic style and the subjects you most often capture.

Which should you buy?

Choosing between the Sony FE 1.4x Teleconverter and the VILTROX 56mm f/1.7 E Lens ultimately depends on your specific needs and budget. If you're looking for a cost-effective, lightweight option for portrait photography, the VILTROX lens at $180.00 is an excellent choice. However, if you require a durable teleconverter that enhances existing lenses for wildlife or sports photography, the Sony teleconverter, despite its higher price of $598.00, offers unmatched optical performance and reliability. Consider your photography style, the types of subjects you shoot, and whether you prioritize budget or specialized functionality.
