Product Overview

Laowa 105mm f/2 Smooth Trans Focus Lens for Pentax K

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 is a short telephoto prime designed for full-frame Pentax K-mount 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 Pentax K-mount 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.

FAQs

What is the advantage of the apodization element in the Laowa 105mm f/2 lens?

The apodization element in the Laowa 105mm f/2 lens serves to enhance the quality of bokeh, which is the aesthetic quality of out-of-focus areas in an image. This element tapers from clear in the centre to denser towards the edges, producing more circular and pleasing out-of-focus highlights. This results in a softer transition between in-focus and out-of-focus areas, making it ideal for portraiture and creative photography where background separation is key.

How does the two-diaphragm design impact my photography?

The two-diaphragm design allows for greater control over both exposure and bokeh quality. The 14-blade diaphragm works in conjunction with the apodization element to fine-tune the out-of-focus highlights, while the 8-blade diaphragm primarily manages light transmission and depth of field. This means you can achieve a desired aesthetic effect in your images while also controlling the overall exposure, giving you versatility in different lighting conditions.

Can I use this lens on APS-C cameras, and what will be the effective focal length?

Yes, the Laowa 105mm f/2 lens can be used on APS-C cameras, where it provides an equivalent focal length of 157.5mm. This makes it an excellent choice for capturing tight compositions, such as portraits or details, with enhanced background separation. The longer effective focal length also offers a different perspective and working distance, which can be beneficial in various shooting scenarios.

What types of photography are best suited for the Laowa 105mm f/2 lens?

The Laowa 105mm f/2 lens is particularly well-suited for portrait photography due to its ability to create beautiful bokeh and selective focus effects. Additionally, it can be effectively used in macro photography, thanks to its close focusing capability of 3 feet and a maximum magnification of 0.16x. The lens's sharpness and control over chromatic aberrations also make it ideal for capturing fine details in other genres such as nature and product photography.

How does the manual focus design of this lens affect my shooting experience?

The manual focus design of the Laowa 105mm f/2 lens provides photographers with precise control over focus, allowing for fine-tuning that can be particularly useful in creative compositions. While it may require a bit of practice to master, this level of control enables you to achieve the exact focus point you desire, especially in situations where auto-focus may struggle, such as low light or complex scenes with multiple subjects.

What is the significance of the lens's T-stop value of 3.2?

The T-stop value of 3.2 indicates the effective light transmission of the lens when using the apodization element. While the lens is labelled as f/2, the T-stop value takes into account the light loss introduced by the apodization element. This means that while you can achieve the selective focus characteristics of an f/2 lens, the actual light reaching the sensor is more akin to that of a T3.2 lens, which is important to consider when planning your exposures in various lighting conditions.
