Sigma 135mm f/1.8 DG HSM Art Review

Sigma 135mm f/1.8 DG HSM Art Handling and Features

In the days when cameras were almost always sold with a 50mm standard lens, the second lens purchase was often the ubiquitous 135mm f/2.8 of maybe 4 or 5 elements. Now we have Sigma's new Art lens to continue the tradition, but with a super bright f/1.8 maximum aperture and a much more complex 13 element in 10 groups construction. There are 2 SLD (Super Low Dispersion) and 2 FLD (Fluorite Low Dispersion) elements, all multi-coated to reduce flare.

The lens looks the part, and clearly, the construction quality is excellent. Sigma tells us that it is hand crafted in Aizu, Japan. It weighs in at a hefty 1130g.

The usual bayonet fit lens hood is large and efficient and surrounds an 82mm filter thread. Behind this is a very wide manual focus ring that can be used when in AF mode to override the focusing position selected and make final adjustments. Focusing is down to 87.5cm (34.4 inches) which gives a maximum magnification of 1:4.3, this being usefully close. A clear window shows the distance scale in feet and metres, but there is no depth of field scale.

There are two switches on the lens barrel, one the AF/MF selector and the other the focus limiter for the AF system. Settings for the latter are full range, 1.5m to infinity and 0.875m to 1.5m. Focusing is swift and accurate in any event, but the choice can be useful for close working.

The lens diaphragm comprises 9 rounded blades to enhance the bokeh, the quality of the out of focus areas in an image. This can help, but in any event, the 135mm will inevitably give impressive selective focus effects.

For those keen to venture out into all weather conditions, the dust and splash proof construction will be a welcome feature. Colours, in particular, can take on a more dramatic, vibrant quality in the rain.

There are no difficulties or operational glitches whatsoever and the lens is a pleasure to use. Controls are smooth and well made with a good feel to them, the finish is excellent and the AF positive and spot on.
