I know there's another thread for this lens, but each of those entries are with APS-C cameras, so I thought I'd start a new one for FF. These are a few I've taken over the past couple of months with a Sony A7 and the Fotodiox adapter. There are some limitations with this lens, but it's capable of producing some pretty decent images. The best thing about this lens is that it's so light and portable. As is well-known with this lens, though, it's not perfect. I pretty much never use it below 2.8, which defeats the purpose of it being a 1.4. (It's okay at f/2, but wider than that it's so soft it looks like nothing is in focus.) Aside from that, the other major issue is vignetting. Even stopped down to f/8 or f/11, for bright scenes be prepared to max out the vignetting fix in post. Wider open and it starts to resemble a view through a telescope the way they show it in movies.
