Venus Optics 105mm f/2.0 overview

  • 1Description

Designed to provide a wealth of control over out-of-focus quality and to enhance bokeh, the Laowa 105mm f/2 Smooth Trans Focus Lens from Venus Optics is a short telephoto prime designed for full-frame Sony E-mount mirrorless cameras. The unique optical design incorporates an apodization (APD) element, as well as two separate diaphragms—8- and 14-blade—to provide separate adjustment over the bokeh as well as the exposure and depth of field. This APD element functions as a radially graduated neutral density filter, and as such limits the light transmission to a T-stop value of 3.2, while permitting the depth of field and selective focus qualities of a true f/2 design.

Alongside the unique attributes of the APD element, the lens also incorporates three low dispersion elements and one extra refractive index element to control chromatic aberrations and color fringing, as well as produce a great deal of overall clarity and sharpness. The lens is also characterized by its manual focus, manual aperture design, that provides a wealth of control over focus and exposure to benefit working with the APD element.

Short telephoto prime designed for full-frame E-mount mirrorless cameras, this lens can also be used on APS-C models where it provides a 157.5mm equivalent focal length.
Optical design incorporates an apodization element that helps to improve the quality of bokeh. This element, which resembles a radially graduated ND filter that tapers from clear in the center to more dense around the edges, produces more circular out-of-focus highlights for more pleasing selective focus and shallow depth of field effects.
To control the effect of the apodization element, two separate diaphragms are incorporated in the lens' design: a 14-blade diaphragm that works mainly in conjunction with the APD element to control bokeh, as well as a standard 8-blade diaphragm at the rear of the lens design to control the overall light transmission and affect depth of field.
Due to the incorporation of the APD element, the lens offers an effective light transmission value of T3.2, while the f/2 designation relates mainly toward the potential for selective focus and depth of field control.
Beyond the APD element, the lens also features three low dispersion elements and one extra refractive index element, which combine to limit chromatic aberrations throughout the aperture range and contribute to a high degree of sharpness and clarity.
A manual focus design permits fine-tuned control for focusing as closely as 3' away with a maximum magnification of 0.16x.
Two manual aperture rings enable you to adjust both the exposure-affecting diaphragm as well as the APD-affecting aperture.

    Venus Optics 105mm f/2.0 reviews

    Laowa 105mm f/2 Smooth Trans Focus Lens for Sony E is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from Beatiful piece of optic Just some add-ons to the Reviews on Photozone and ePhotozine: - the hood is flimsy - when focused somewhere between 7 feet and infinity, there opens a small gap between the barrel and the front element, which might (or might not) be a problem in dusty environment - everything works nice and smooth and seems well made - with the a7rii I had no exposure issues (just left the camera in P-mode) as described for the Nikon D810 or handling problems as described for the Nikon D810 and Canon 5Ds R - the fucos ring turns a full 270 degree and with the focus assist (magnification) and the well damped focusring is is really a plaesure to focus - beautiful background blur - The lens is sharp

    Rated 5 out of 5 by from Perfect portraits with Sony E Sharp subjects and fabulous bokeh. Lens is solid metal. Focusing with the Sony A6300 is easy using the camera's highlighting feature. I suspect focusing with a DSLR might be difficult unless you use the screen and magnification.
