Tamron's new trio of compact, 1:2 macro prime lenses includes a 35mm F2.8, a 24mm F2.8, and this lens, a 20mm F2.8 for Sony's full-frame E-mount cameras. We found that the lack of a super-fast maximum aperture is at least partially made up by the impressive close-focusing distance, and the lens is weather-sealed and affordable to boot. Take a look at what this lens can do on a 61MP Sony a7R IV, and catch a glimpse of some Seattle snow while you're at it.
