The Venus Optics Shift Lens Support for Laowa 15mm f/4.5 is an accessory that gives you improved mounting and makes it easier to shoot shift-type stitched panorama photos without parallax errors.
This support clamps to the front of the lens for stability and has a tripod foot for direct mounting. It keeps the optical axis fixed when you’re using the lens’s shift adjustment, helping to reduce unwanted perspective distortion and enable more accurate, repeatable results. It has a series of index notches that work in tandem with the lens barrel for accurate registration depending on the direction of the shift.
And there’s a built-in bubble level!
