Venus Laowa 15mm F4 1:1 Macro
|I own it||I want it||I had it|
The LAOWA 15mm lens is one of the widest full-frame lenses to offer a full 1:1 magnification ratio. Admittedly, this magnification only occurs when the object is 0.2 inches (4.7mm) from the rather large front element of this lens, but that's the trade off between a wide angle of view and the desire for 'true' macro abilities.
In addition to the headline feature, this entirely manual lens (manual focus; manual aperture; no communication to the camera body) also includes a shift mechanism to physically move the optics up or down along the lens mount. This shift provides perspective correction for converging lines, as well as a way to create seamless panoramas (though the shift direction is fixed to the frame's vertical axis).
