The Tamron 14-150mm f/3.5-5.8 Di III is a wide-angle to telephoto super-zoom lens designed for Micro Four Thirds compact system cameras. Boasting a 10.7x zoom range, compact and lightweight design, a 52mm filter thread and a metal lens barrel exterior, the Tamron 14-150mm f/3.5-5.8 Di III costs around £389 / $589 and is available in silver or black.
Ease of Use
The Tamron 14-150mm f/3.5-5.8 Di III is quite light considering the 10.7x zoom range on offer, weighing in at 285g. It certainly doesn’t feel too weighty in the hand and proved to be well balanced on the Panasonic Lumix DMC-GX7 that we tested it with. The lens does extend by about an extra 4cm when fully zoomed out to 150mm, where it starts to look a little incongruous.
The rear element is surrounded by a metal lens mount and hides 17 elements in 13 groups, including one LD (Low Dispersion) glass element, two AD (Anomalous Dispersion) glass elements, two Molded-Glass Aspherical elements and one Hybrid Aspherical element. That’s a lot of glass for the light to go through and is under continuous threat of dispersion. There are seven aperture blades for the aperture range which reaches a minimum of f/22. There’s no distance scale or depth of field scale.
The Tamron 14-150mm f/3.5-5.8 Di III features a form of stepping motor which provided almost silent, quick and generally accurate auto-focusing on the Panasonic GX7 that we tested it with. The manual focusing ring is a little slim, though, and has no hard stops at either end.
