Review

The Canon RF-S 3.9mm F3.5 STM Dual Fisheye lens is an innovative addition to Canon's RF lens lineup. This unique lens offers an intriguing perspective that caters to both enthusiasts and professionals interested in creating immersive 360-degree content. With its dual fisheye design, it ensures users can capture striking spherical images and videos, making it an essential tool for virtual reality (VR) and panoramic photography.

Build and Design

The first thing that stands out about the RF-S 3.9mm F3.5 STM Dual Fisheye is its compact size and lightweight design. At just a few hundred grams, it’s incredibly portable, which is perfect for travel or on-location shoots. The lens features a sleek construction with a metal mount that gives it a solid feel despite its lightweight body. Its minimalist aesthetic complements Canon’s modern RF camera bodies, and the small form factor means it can be easily stored in a camera bag without taking up too much space.

Image Quality

When it comes to imaging performance, the Canon RF-S Dual Fisheye lens impresses with its ability to produce vivid colors and sharp details across its entire field of view. The F3.5 aperture allows for decent low-light performance, although it's worth noting that, like many fisheye lenses, it can introduce noticeable distortion. However, this is often desired in creative applications where the warping of lines contributes to the overall effect. The lens also features advanced coatings that reduce flare and ghosting, enhancing the overall image quality.

Focusing and Use

The stepping motor (STM) technology provides smooth and quiet autofocus, which is beneficial for both video work and capturing fast-moving subjects. While fisheye lenses typically have a deep depth of field, allowing users to focus on subjects close or far away, the RF-S Dual Fisheye excels in offering versatility in framing. The lens allows for creative shots, whether you're capturing landscapes, architectural structures, or unique perspectives on everyday objects.

Compatibility

Since this lens is designed for the Canon RF mount, it is most compatible with Canon’s latest mirrorless camera systems. It’s essential to consider that this lens is more specialized compared to traditional prime or zoom lenses, limiting its use for those who primarily shoot general photography. However, for those venturing into 360-degree content creation, it opens up a new realm of creative possibilities.

Pros and Cons

Pros

• Compact and lightweight design for portability.

Its compact size, excellent image quality, and smooth autofocus make it a fantastic option for capturing unique perspectives. While the distortion may not appeal to everyone, it is a welcomed characteristic in the world of fisheye photography. Overall, if you're in the market for a lens that specializes in 360-degree images and VR, the RF-S Dual Fisheye is certainly worth considering.
