Zeiss Milvus 50mm f/1.4 Review

October 27, 2015 | Mark Goldstein | |

Introduction

The Zeiss Milvus 50mm f/1.4 is a manual-aperture, manual-focus standard prime lens for Canon and Nikon full-frame mirrorless cameras. It features an aperture range of f/1.4-f/16, 10 elements in 9 groups, a nine-bladed circular diaphragm for smoother bokeh blur in out of focus areas, and a precision-engineered full-metal casing. The Zeiss Milvus 50mm f/1.4 retails for £949 / €1199 / $1199.

Ease of Use

Weighing around 900g and measuring 109mm in length, the all-metal Zeiss Milvus 50mm f/1.4 is a very big and heavy lens considering the moderate 50mm focal length on offer. It feels quite well-balanced on the Canon EOS 5DS R that we predominantly tested it with.

The Zeiss Milvus 50mm f/1.4 boasts superb build quality. The lens’ all-metal casing is dust and moisture resistant and it features a metal mount. With no need for a zoom ring, the manual focussing ring spans a significant width of the lens barrel and is exceptionally smooth to operate, complete with a useful depth of field scale and hard stops at either end.

The Zeiss Milvus 50mm f/1.4 has 10 lens elements in 9 groups with four anomalous partial dispersion glass elements and one aspherical element to help reduce chromatic aberrations. A nine-bladed rounded diaphragm, combined with the fast maximum aperture, helps provide very smooth bokeh blur.

There's no optical image stabilisation, but the lens' standard focal length and very fast maximum aperture alleviate the need for it. A special sealing ring on the bayonet also protects the interface between the camera and the lens. A round metal lens hood is supplied.

Focal Range

The 50mm focal length gives an angle of view of 46° on a 35mm full frame sensor.

Manual Focussing

The Zeiss Milvus 50mm f/1.4's manual focussing ring spans a significant width of the lens barrel and is exceptionally smooth to operate, complete with a useful depth of field scale. It also has a large rotation angle which enables precise focusing and moves smoothly without any play, thus also supporting the intuitive interaction with the focal plane. The precise engravings in meters and feet, together with the depth of focus scale, help make manual focusing a veritable pleasure, especially in conjunction with the excellent Peaking feature offered by the Sony A-series cameras.

Chromatic Aberrations

Chromatic aberration (purple fringing) is rarely an issue with the Zeiss Milvus 50mm f/1.4, so much so that we could only find a few instances of fringing in our test shots.

Light Fall-off and Distortion

Light fall-off is noticeable wide open at f/1.4, though this is to be expected for such a fast lens and can easily be corrected in Photoshop. Stop down to f/2.8 and the vignetting is already less prominent, but it is still visible when shooting pale scenes that fill the frame.

Macro

The Zeiss Milvus 50mm f/1.4 is not a macro lens, with the close-focus point at 45cm from the film/sensor plane and a maximum reproduction ratio of 1:6.7 . The following example illustrates how close you can get to the subject, in this case a CompactFlash card.

Bokeh

A major appeal of fast, wide-aperture prime lenses is their ability to produce an eye-catching separation between a sharp subject and a very soft out-of-focus background. The Zeiss Milvus 50mm f/1.4 generates very smooth out of focus areas through its use of a 9-bladed diaphragm, which provides smoother bokeh than seven or five-blade designs. Bokeh is however a fairly subjective part of a lens' image quality, so check out these 100% crops to see the Zeiss Milvus 50mm f/1.4's bokeh quality for yourself.
