For the next few days I've decided only to use my new vintage Russian Tair-11 lens. It arrived from Moscow just before New Years eve, and I find it's a bit more challenging to get to know this lens compared to the other vintage lenses, that I own. Some of it is due to its preset aperture system, but some of it is also because it's quite heavy to be carrying around. The Tair-11 weighs 564 grams) and feels like a huuuuuuge tank when mounted on my Olympus OM-D E-M mirrorless ( which is also a quite small camera body)...
