Atypical for a macro lens, the focal length of 150 mm distinguishes the representative of the Sigma company from other lenses with a magnification of 1: 1.
Pro
The EX marking indicates that the lens belongs to the professional segment — it boasts high-quality assembly, dust and water protection and a pleasant soft pattern. Numerous reviews on the World Wide Web confirm the high level of the macro lens and put it on a par with the best solutions from a-brands (Canon and Nikon).
Autofocus
A quiet and fast ultrasonic focus motor has found shelter on board the lens. The speed of its work directly depends on the minimum focus distance — the larger it is, the faster the automatic focus is carried out. At a minimum distance (38 cm), autofocus can be a little blurry, but there is always the possibility of manual fine-tuning.
tripod platform
A tripod platform is located on the bottom of the lens. It allows you to install a 900-gram lens on a tripod or attach an additional light source to it — due to the small depth of field at such a high focal length, you have to cover the aperture to f / 11-f / 16, so shoot handheld without additional support or a third-party light source becomes difficult. Moreover, the lens does not have a built-in image stabilization system.
Ratings
The APO symbols in the lens markings indicate the use of low dispersion lenses in the optical design, which effectively combat chromatic aberrations. The macro lens is practically unrivaled in terms of sharpness — its level is very high even from the maximum aperture, and drops to the “Good” mark only at f / 16.
Without trunk
The long focal length is great for shooting various insects. The main advantage in this case is internal focus — the lens is devoid of moving parts and will not frighten away the subject during the focus process.
The telemacro lens makes it possible to take superb full-size photographs of miniature objects. Due to its excellent performance, the lens provides the highest image quality when used with digital cameras. Design features have minimized the occurrence of magnification chromatic aberration, which is especially prone to digital camera optical systems. The optical scheme of the lens includes elements of low dispersion glass (SLD, Special Low Dispersion), which guarantees effective suppression of various types of aberration. Not only automatic, but also manual focus is possible. Combined with the Sigma EX 1.4x and 2x teleconverters (sold separately), the lens extends the focal length to 210mm/F4 and 300mm/F5.6.
