Laowa 100mm f/2.8 2X Ultra Macro APO

Reviewers report very high sharpness from f/2.8 across the frame, with f/4–f/8 the best range. Bokeh fringing is almost absent, longitudinal CA does not grow at close range, distortion is low, and the overall rendering is pleasant. At its price it was widely recommended for anyone who does not need autofocus.

Vignetting wide open is the main optical weakness. Lateral CA is moderate rather than zero, and bokeh on the 7-blade Nikon version was criticised. The 13-blade Sony version avoids that problem.

Owners like getting 2x magnification and APO-level colour correction for less than a first-party 1x macro, and the extra working distance over the 58mm and 90mm is appreciated for insects. The build is solid and the focus ring smooth with a long throw.

Sony users mention the length and front-heaviness of the FE version, the lack of EXIF and in-camera aperture control, and the need to stop down manually before metering. Several say the newer 90mm is the better buy for Sony now, though the 100mm is often cheaper on the used market.
