Tamron has unveiled three much-leaked new prime lenses for full-frame Sony mirrorless cameras. The 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 are all compact, lightweight wide-angle prime lenses that boast a 1:2 magnification ratio and very close minimum focus distances so that they can be used for every-day shooting and macro photography.
As these lenses leaked over the past month, a consistent question we saw in the comments was: who wants f/2.8 wide-angle prime lenses? Since many of the most popular wide-angle primes come with f/1.8 apertures or brighter, it seemed like a strange decision from Tamron. Now we know why. The lens maker wanted to produce three prime lenses that would be ultra-portable and extremely versatile.
All three lenses weigh less than 8oz, measure just 2.5 inches long, and use the same 67mm filter thread as Tamron’s other FE-mount mirrorless lenses. This, combined with a minimum focusing distance of 4.3, 4.7 and 5.9 inches for the 20mm, 24mm and 35mm lenses, respectively, makes for three versatile carry-everywhere lenses that balance almost identically on Sony’s full-frame mirrorless cameras.
“Being able to get in close is one of the most desirable specifications for a wide-angle lens,” boasts Tamron. “With dramatic closeup shooting performance for full-frame lenses, the series unleashes an unprecedented level of shooting freedom. Plus, by moving close to the subject, strongly blurred backgrounds are easier to attain.”
Translation: this is why it’s okay that we released three prime lenses with an f/2.8 maximum aperture.
Here’s a closer look at all three lenses, followed by some official sample photos from each lens.
