Review of Zeiss Otus ML 35mm f/1.4 Lens: Traditional Optical Design and Performance

Zeiss has released the Otus ML 35mm f/1.4 lens, priced at $2,299, which continues the company's commitment to traditional optical engineering without relying on digital corrections for issues like distortion and vignetting. The lens is designed for mirrorless cameras, available in Sony E-mount, Canon RF-mount, and Nikon Z-mount, and features a solid metal construction with manual focus and aperture rings. It weighs approximately 24.7 ounces (700 grams) and uses 67mm filters, lacking customizable buttons or switches. The manual focus has a long throw, which can be challenging for fast subject acquisition. Build quality includes effective sealing against dust and moisture, a metal lens hood, and electronic connectivity for EXIF data transfer. Optical performance shows excellent flare resistance due to T* coatings, smooth bokeh with minimal artifacts, and strong control over chromatic aberrations, though longitudinal chromatic aberration (LoCA) is present at wider apertures, causing color fringing that diminishes at around f/4. Sharpness is high in the center and corners, with minimal vignetting. The review notes that while the lens excels in optical correction, similar results can be achieved with software for digital cameras, making the high price less practical for many users. Alternatives like the Sigma 35mm f/1.4 Art II offer autofocus, competitive image quality, and a lower cost, while the Nikon Z 35mm f/1.4 and Nikon 35mm f/1.2 S provide other options. The lens appeals to purists who value traditional design, but its market is limited due to cost and practicality concerns.
