Maciej Latałło has just posted a full review of the newly released Tamron 17-70mm F2.8 Di III-A VC RXD Lens (Amazon/ B&H/ Adorama) at the LensTip.com. He tested this new lens on Sony a7R III and found such pros: very good image quality in the frame centre across the whole focal range, sensible image quality on the edge of the frame, lack of any serious problems with longitudinal chromatic aberration, slight lateral chromatic aberration in the 30-70 mm focal range, good coma correction, moderate astigmatism, silent and very quick autofocus, efficient image stabilization, and unique combination of focal range and aperture fastness.

Sigma has just officially announced the Sigma 56mm F1.4 DC DN C lens for Fujifilm XF mount. It is characterized by its bright f/1.4 maximum aperture, which suits working in difficult lighting conditions and also offers improved control over depth of field for isolating subjects and working with selective focus techniques. The optical design utilizes two aspherical elements and one SLD element, which help to reduce both spherical and chromatic aberrations for greater sharpness and clarity. A super multilayer coating has also been applied to suppress flare and ghosting in order to achieve more contrast and color accuracy when working in strong lighting conditions. Complementing the optics is a stepping AF motor, which suits both photo and video applications due to its quick, precise, and near-silent performance.
Sigma has just officially announced the new Sigma 16mm F1.4 DC DN Contemporary Lens for FUJIFILM X mount. It is a fast portrait prime lens, featuring 16 elements in 13 groups, a minimum focus distance of 25cm (9.8”) and 405g (14.3oz).
Sigma has just officially announced the new Sigma 30mm F1.4 DC DN Contemporary for Fujifilm‘s APS-C X-mount camera systems. It has a fast stepping motor for smooth and quiet focusing during video recording. It has both aspherical and double-sided aspherical elements, nine rounded aperture blades and a minimum focus distance of 30cm/11.9in.
Along with the OM-1 Camera (Amazon/ B&H/ Adorama), OM System 12-40mm F2.8 PRO II (Amazon/ B&H/ Adorama), OM System also announced the new OM System 40-150mm F4.0 PRO Lens. It is a weather-sealed telephoto zoom lens that offers an 80-300mm full-frame equivalent field of view. The lens is IP53 rated for dust- and splash-resistance when paired with a weather sealed camera, such as OM System’s new OM-1 Micro Four Thirds camera. It’s constructed of 15 elements in nine groups, uses a seven-blade circular aperture diaphragm and has a minimum focusing distance of 70cm (27.5″). The lens’ autofocus (AF) is driven via OM Systems’ Movie & Still Compatible (MSC) system, which OM Systems claims ‘benefits both photo and video applications due to its smooth, quiet, and fast performance.’
