Photographer and self-professed weird lens guru Mathieu Stern is back with another interesting bit of photo gear. Unlike many of his videos, like this one about shooting with a Canon X-ray lens, Stern's newest video is about a modern, commercially available product, the Fotodiox RhinoCam Vertex Rotating Stitching Adapter. The RhinoCam Vertex allows you to attach a medium format lens to a full-frame mirrorless camera, including Canon RF, Nikon Z and Sony E-mount cameras. Compatible lenses include Bronica ETR mount, Pentax 6x7 (P67), Pentax 645 (P645) and Hasselblad V-Mount.

The RhinoCam Vertex rotates your camera on the lens to allow you to capture four different images, which can be used to stitch a 6x6 digital medium format image. The adapter takes advantage of the large image circle of a medium format lens relative to a full-frame image sensor. With a medium format lens attached to the RhinoCam Vertex and mounted on your camera, you then rotate the camera 360 degrees in 90-degree increments to capture four images around the center of the lens. Using digital stitching software, such as Photoshop, you then stitch the images into a panorama, replicating a medium format 'look' and resolution.

Mathieu Stern went hands-on with the RhinoCam Vertex in his latest video. In his video, Stern used a Zenza Bronica Zenzanon-PE 75mm F2.8 lens on his Sony A7R III. Stern shows an overview of the adapter from Fotodiox, which is available in full further down, and shows some of his images. As you can tell, Stern is a big fan of the RhinoCam Vertex.

Fotodiox has published a couple of videos about the RhinoCam Vertex since releasing it earlier this year. The first video below is a general overview video of the product. By stitching together four full-frame images captured using a medium format lens, you can create an image with about 2.5 times the resolution of a standard full-frame image.

The overview video also gives a step-by-step guide on using the RhinoCam Vertex, including recommended camera settings. It also shows a simple Photoshop workflow to stitch your panorama. The second video is a more in-depth look at using the RhinoCam Vertex and offers additional tips for using the adapter and stitching your images.

The Fotodiox RhinoCam Vertex is available now for $299.95. As mentioned, it's available for Canon, Nikon and Sony mirrorless cameras, and there are versions available that accept Pentax, Bronica and Hasselblad medium format lenses. The RhinoCam Vertex is constructed using anodized aluminum and includes a rotating camera mount and a built-in 1/4"-20 tripod mount.
