Big and heavy, but beautiful.
You may obtain very crisp images from this lens, but you have to put it on a rock-solid tripod (or shoot whit a lot of light at high speeds), maybe interlocking something between the tripod mount and the lens itself to avoid vibrations (often a rollfilm plastic case filled with something is good enough).
It could be a useful travel companion, but for my tastes is too dark, so I use it mainly for landscape and macro work.
It is sharp wide open, and past two stops down don’t improve so much.
