Tamron 14-150mm f/3.5-5.8 Di III Lens Gets DxOMarked
Tamron 14-150mm F/3.5-5.8 Di III VC (Model C001) Micro 4/3 vs. Panasonic LUMIX G Vario HD 14-140mm F4.0-5.8 ASPH vs. Panasonic LUMIX G VARIO 14-140mm / F3.5-5.6 ASPH. / POWER O.I.S
From DxOMark conclusion:
Although the Tamron isn’t quite up to the optical performance of the equivalent offering from Panasonic, it isn’t bad by any means, particularly at the shorter focal lengths. In fact, it is very similar in performance to the original 14-140mm f/4-5.8 ASPH. The large zoom range makes lenses like this particularly attractive to video users, and at around half the price of the new Panasonic model, the main draw will be the accessibility. However, the slightly longer reach, compact dimensions and durable metal construction all add to the appeal.
Tamron 14-150mm F/3.5-5.8 Di III (model C001) is a superzoom lens for Micro Four Thirds cameras, offers a 28-300mm equivalent range and uses a stepper motor for silent autofocus (including during video recording).
