Several days in a row, I portraited spiders feeding their bumblebee sausages (wrapped, etc., usual spider cuisine) with various 50mm lenses. Today I decided to take the 90/2.5 Tamron macro lens from the eighties (model 52B), a very sharp and well-corrected lens, and well manufactured in addition.
As a general purpose lens, it does a good job but looks a bit bland, lacking contrast. For close-ups, it is more convincing. The attached pics are two crops, a partial one (the lens reaches 1:2 and even 1:1 with its native extension tube, but I could not get closer so it was maybe 1:3, hence the crop) and a 100% one, the latter to give you an idea of the optical qualities. Shot at f/8 with the Df, handheld, 1/250s, 2500 ISO, some wind.
