Product Information

Full details

The Laowa 100mm f/2.8 2X Ultra Macro APO lens is designed for macro photographers and portrait enthusiasts who demand extreme detail and optical clarity. Its standout feature is an impressive 2:1 magnification ratio, allowing you to capture subjects twice their life size, combined with an apochromatic design that virtually eliminates color fringing. While this lens offers exceptional image quality, it is a manual focus-only optic, requiring users to be comfortable with manual focusing techniques for both macro work and general photography.

FAQs

Can I use this lens for portraits?

Yes, it is highly capable as a portrait lens as it can focus to infinity and produces excellent sharpness with pleasant bokeh.

Does this lens have autofocus?

No, the Laowa 100mm f/2.8 is a manual focus-only lens.

Does it work with full-frame cameras?

Yes, this lens provides full-frame sensor coverage.

Is a tripod required?

While not strictly required, a tripod is highly recommended for 2:1 macro shots due to the extremely shallow depth of field and susceptibility to camera shake.

What is the filter thread size?

The filter thread size is 67mm.

How does the APO design help?

The APO design minimizes chromatic aberration, preventing unsightly color fringes around high-contrast edges in your images.

Troubleshooting

Aperture settings are not changing on the camera screen.

Ensure the lens is fully locked into the camera mount and the aperture ring (if present) is set to the 'A' position or the software settings are correctly configured for manual lens communication.

Images are blurry even at fast shutter speeds.

Verify that your manual focus is precise. At 2:1 magnification, depth of field is razor-thin; use Live View magnification to confirm focus before taking the shot.

Pros and Cons

Pros

Twice the magnification of standard macro lenses (2:1)
Excellent control over chromatic aberration due to APO design
Dual-purpose functionality for both macro and portraiture
Communicates aperture settings directly with Pentax camera bodies
Compact and lightweight design for field use

Cons

Manual focus only operation
Requires practice for steady handheld macro shooting
Lack of image stabilization means a tripod is often necessary for 2:1 shots

Setup, Compatibility & Care

This lens is specifically designed for Pentax K-mount SLR cameras. To set up, simply align the red index on the lens with the mounting indicator on your camera body and twist until it clicks into place. The aperture coupling lever is built into the mount, so you do not need to perform additional steps to enable aperture control from the camera body.

For care, store the lens in a cool, dry place with the front and rear caps attached when not in use. Clean the optical elements only with professional-grade lens tissues and a blower bulb to avoid scratching the coatings. If shooting in dusty environments, be mindful that the focus mechanism extends slightly as you focus closer to 2:1, so keep the lens barrel clean to prevent debris from entering the focus rings.
