新品丨佳能发布APS-C画幅VR镜头RF-S3.9mm F3.5 STM DUAL FISHEYE

On June 11, 2024, Canon (China) Co., Ltd. ※1 released the RF-S3.9mm F3.5 STM DUAL FISHEYE lens, which is suitable for APS-C format youth professional micro ※2 (currently only supported with EOS R7※3 used). The launch of this lens expands the EOS VR system lineup and further lowers the threshold for VR photography. RF-S3.9mm F3.5 STM DUAL FISHEYE is the first VR lens in the RF-S lens group. It has a viewing angle of 144° and is compact and lightweight. When paired with EOS R7, it can form a highly mobile and portable 3D VR shooting combination. It brings more convenience to the daily shooting of 3D VR content creators; it brings new imaging equipment to the film, education, games, tourism, real estate, sports and other industries.

Canon RF-S3.9mm F3.5 STM DUAL FISHEYE lens

In order to allow Canon EOS R7 to shoot 3D images with natural parallax (baseline length is 60mm), RF-S3.9mm F3.5 STM DUAL FISHEYE is equipped with a prism that can bend the light path, which can not only easily shoot 3D VR images, but also Can maintain versatility. The lens structure of the RF-S3.9mm F3.5 STM DUAL FISHEYE has been optimized for short back focus and bent light paths. Two UD lenses on each side achieve excellent high image quality throughout the entire frame. When shooting 4K short films using the EOS R7 and the RF-S3.9mm F3.5 STM DUAL FISHEYE lens, the resolution is comparable to that shot using the EOS R5 and the RF5.2mm F2.8 L DUAL FISHEYE lens.

Thanks to the 144º viewing angle, when shooting with the RF-S3.9mm F3.5 STM DUAL FISHEYE

Other photography equipment (such as tripods, microphones) will not be included in the picture

The viewing angle of the RF-S3.9mm F3.5 STM DUAL FISHEYE is 144º. When recording 4K movies, the number of pixels per 1º of viewing angle reaches a similar pixel density as using the RF5.2mm F2.8 L DUAL FISHEYE. Like the RF5.2mm F2.8 L DUAL FISHEYE lens, the left and right lenses of the RF-S3.9mm F3.5 STM DUAL FISHEYE are equipped with electromagnetic drive apertures (EMD). Simultaneous control of the two electromagnetic drive apertures allows the RF-S3.9mm F3 .5 STM DUAL FISHEYE gets the same exposure with both lenses.

EOS R7 equipped with RF-S3.9mm F3.5 STM DUAL FISHEYE lens

The RF-S3.9mm F3.5 STM DUAL FISHEYE is the first non-L-class lens to feature Canon’s Air Spherical Coating (ASC) technology. ASC coating can provide stronger anti-reflective properties than traditional evaporated multi-layer coatings. When used on lenses with large curvatures such as the RF-S3.9mm F3.5 STM DUAL FISHEYE, it can also reduce lens flare and ghosting. The maximum aperture of RF-S3.9mm F3.5 STM DUAL FISHEYE is F3.5, which ensures VR image clarity even in low-light environments, improving detail richness and realism.

The gear-type stepping motor equipped on the RF-S3.9mm F3.5 STM DUAL FISHEYE has a dual-lens autofocus mechanical structure that can drive the left and right lenses at the same time. Therefore, autofocus can be achieved and is as simple to operate as an ordinary Canon RF lens. The high-performance microprocessor matches the drive motor control with the camera's autofocus algorithm to achieve high-speed, high-precision autofocus.

Left and right focus difference adjustment mode switch and focus

The control ring can adjust the focus deviation of the left and right lenses

RF-S3.9mm F3.5 STM DUAL FISHEYE is designed with a focus/control ring. The left and right focus differences can be adjusted through the focus/control ring and focus difference adjustment mode switch. The RF-S3.9mm F3.5 STM DUAL FISHEYE is equipped with a drive motor that can drive only the right lens alone. In this way, the left and right focus difference adjustment mode switches and the focus/control ring can be used to adjust the focus deviation of the left and right lenses.

Filters need to be cut by the user

The RF-S3.9mm F3.5 STM DUAL FISHEYE lens can use two filter holders: one can install a threaded ND filter with a diameter of 30.5mm; the other can use the included plug-in filter holder, which will be commercially available After the gelatin filter is cut to the appropriate size, it is inserted into the filter holder at the rear of the lens.

EOS VR shooting and production are very simple and only include four parts: shooting, viewing, conversion and editing. Using the EOS VR Utility dedicated application can help users easily convert captured short videos and photos into virtual reality (VR) images. VR images can be converted in one go using the camera's design values and shooting data. Released this time along with the RF-S3.9mm F3.5 STM DUAL FISHEYE is version 1.4 of the EOS VR Utility / EOS VR Plugin.

Compared with the previous version, version 1.4 adds many new features as follows:

·Support APS-C format micro camera

·Support remote shooting and autofocus functions

· Can convert 144º viewing angle data into 180º VR images

· Added anti-shake function (IS)

· Optimized the software interface and improved other functions

※2 As of the release of RF-S3.9mm F3.5 STM DUAL FISHEYE, it only supports Canon EOS R7 body.

※3 The firmware of EOS R7 needs to be updated.

※4 Some functions require payment.
