>>3888423I've got one of those. Beware, the aluminium focus ring will feel brittle like an eggshell, and given your amerifat trucker hands, it might actually end up being that way. Look for a way to attach a focusing tab or some kind of focus aid to it, because it's the squeezing that one has to do to turn it, that feels dangerous about using it.

This is a lens for people with shitty scanning setups, honestly, and those who adore Sonnars but for some reason won't just get the 7artisans 50mm f/1.1.
