Yesterday I received a Tamron 200-400mm I purchased from PV Hiker, and this evening I got a chance to take it out for the first time. I wasn't expecting much since it was below freezing with an icy wind, so I was pleasantly surprised to see some ducks I've been watching for. They had been around last year, and on some warmer days this winter. I was fairly satisfied with the images, being my first time with the lens and on an awfully cold and windy day. They're not perfect, so constructive criticism is welcome.
