Design and Build Quality

Compact and Lightweight Design

The Viltrox AF 40mm f/2.5 FE Lens features a compact design that suits everyday use. You can carry it with your camera without adding much bulk. Therefore, it works well for travel, street photography and casual photo walks.

Furthermore, its black finish gives the lens a clean, modern look. The compact form also makes it convenient to store in a camera bag alongside other essential gear.

Performance

Bright f/2.5 Aperture

The Viltrox AF 40mm f/2.5 FE Lens offers a maximum aperture of f/2.5. This helps you shoot in lower light and control background blur. In addition, it gives you more flexibility when shooting portraits, indoor scenes and evening street photos.

You can also adjust the aperture up to f/16 for greater depth of field. Therefore, the lens can handle a wide range of everyday subjects. Its seven-blade aperture helps create a pleasing background blur.

Sharp Images and Optical Quality

The lens uses 10 elements in 6 groups. Its optical design includes one ED element, three high-refractive-index elements and one aspherical element. These elements help control optical issues and maintain image clarity.

Moreover, the lens uses a multi-layer coating to help reduce flare and ghosting. As a result, you can capture clear images with good contrast in different shooting conditions.

Features of the Viltrox AF 40mm f/2.5 FE Lens

Fast and Quiet Autofocus

The built-in STM autofocus motor provides quick and quiet focusing. This makes the lens useful for both photography and video recording. Furthermore, it supports face and eye detection when used with compatible Sony cameras.

You can also switch to manual focus when you want more control. Consequently, the lens suits beginners and experienced photographers alike.

Versatile 40mm Focal Length

The 40mm focal length provides a natural-looking perspective. It works well for portraits, street photography, travel and everyday scenes. Additionally, you can use it to capture environmental portraits that show both the subject and their surroundings.

The lens also offers a minimum focusing distance of approximately 34 cm. Therefore, you can photograph smaller subjects and everyday details without needing a dedicated macro lens.

Connectivity and Compatibility

Sony E-Mount Camera Support

The Viltrox AF 40mm f/2.5 FE Lens is designed for Sony E-mount mirrorless cameras and supports full-frame coverage. It can also be used on compatible APS-C Sony E-mount cameras, where the field of view becomes narrower.

Furthermore, the lens supports EXIF data transmission, which allows supported camera bodies to record lens information with your images. Its USB Type-C interface supports firmware updates. However, check the current firmware instructions and your camera's compatibility before updating.

Battery and Power

Powered by Your Sony Camera

The Viltrox AF 40mm f/2.5 FE Lens does not require a separate battery. Instead, the compatible camera powers its electronic autofocus and aperture functions.

Because of this, you do not need to charge a separate lens battery. Your camera's battery life will depend on the camera model, autofocus use and shooting conditions.

Best Uses for the Viltrox AF 40mm f/2.5 FE Lens

Everyday Photography and Travel

The compact design makes this lens a practical option for daily use. You can carry it for city walks, holidays and casual outings. Moreover, the 40mm focal length works well for scenes that include both people and their surroundings.

Portraits and Street Photography

The f/2.5 aperture helps separate subjects from the background. As a result, you can create portraits with a soft background while keeping the main subject prominent.

Additionally, the quiet autofocus helps when capturing candid moments. This makes the lens useful for street photography and everyday portraits.

Video and Content Creation

The quiet STM motor makes the lens suitable for many video applications. You can use it for talking-head videos, personal projects and general content creation. However, the lens does not have built-in optical image stabilisation, so a stabilised camera body or other stabilisation method can help reduce camera shake.
