Tamron has announced three compact F2.8 prime lenses as well as the development of a 70-180mm f/2.8 Di III VXD (Model A056) lens for Sony E-mount full-frame mirrorless cameras. These ‘Di III OSD M1:2’ lenses come in three focal lengths: a 20mm f/2.8 Di III OSD M1:2, 24mm f/2.8 Di III OSD M1:2, and 35mm f/2.8 Di III OSD M1:2 lens. The set serves as an accessible means for Sony photographers looking to build a collection of wide-angle primes. All three lenses are compact and lightweight, guaranteeing they won’t take up too much space in your bag.
The lenses are the same size and same weight (around 215g/7.6oz), and use the same 67mm filter thread. Minimum focus distances range from 11 to 15cm (4.3″ to 5.9″) and the maximum magnification of all three is 0.5x. The three lenses use both aspherical and low-dispersion elements and feature ‘BBAR’ coatings to reduce flare and ghosting. The lenses use DC motors to drive their focus group, and Tamron says that they are fully compatible with Sony’s latest AF systems. The lenses are also sealed against dust and moisture.
All three lenses are priced at $349. The 24mm and 35mm will arrive on November 20th, with the 20mm to follow in January. Check out the press release and pre-orders are open at Adorama and B&H:
