Tamron 20mm f/2.8 Di III OSD M1:2 Lens: Perfect for Sony Full Frame/APS-C E-Mount Camera Enthusiasts Review

Received my Tamron 20mm on May 6th, 2020. I have a Tamron 28-75mm and am very happy with it. The lens is sharp, small and light. I bought it to photograph New York architecture. Sometimes the lens would focus and sometimes it would miss. I photographed the Manhattan Bridge from the top of Brooklyn and on several occasions the camera displayed two focus boxes indicating the bridge was in focus, but it wasn't.

After returning from a trip to the Smoky Mountains, I was amazed at the photos captured with…

Update: I'm giving this lens a high rating because of the results I've been able to get with it. It's still not a premium build quality lens, my overall impression of the plastic is "eggshell", it buzzes at idle on your camera in manual focus mode, but it's very sharp even wide open and great for astrophotography and landscapes. Whatever its shortcomings, it's the end product that counts. - Initial Review - I wanted a 20mm lens for landscape photography and wanted to see how a $250-$300 Tamron…
