The Venus Optics Laowa 15mm f/4 Macro is a third-party specialty lens designed for Nikon F-mount cameras. Key features include:
- Ultra-Wide 1:1 Macro. This unique lens offers 1:1 macro magnification with an ultra-wide perspection. This is great for accentuating exaggerated perspectives. It provides full-frame coverage for macro compatibility, and its minimum focus distance of 4.7" (0.2" working distance) makes shooting in extremely tight spaces possible.
- Perspective Control. In addition to being a true 1:1 macro lens, the Venus 15mm Macro features +/- 6mm of vertical shift adjustment with APS-C sensor coverage. Seeing as the lens focuses out to infinity, this makes it an ideal candidate for architectural use.
- Optics. The nine group / twelve element optical formula was designed to minimize distortion. Internal focusing helps in that regard, as well as preventing barrel extension. The nearly circular 14-blade aperture renders a creamy background blur.
- Fully Manual. With both manual focus and manual aperture rings, the lens provides no electrical communication with the camera. Therefore, lens information is not included in EXIF data.
