The Tamron 24mm F2.8 Di III OSD M1:2 debuted late last year alongside 20mm and 35mm options. These full-frame E-mount primes offer 1:2 macro reproduction at an affordable $350 price point. Not to mention that they're extremely lightweight: the 24mm F2.8 weighs 215.5g / 0.5lb. That's an extremely attractive feature if you're looking to, for example, hike up a mountain. Take a look at how it handles subjects near, far and somewhere in between.
