I have a Nikkor 1.2 on the way via UPS. Manual focus, of course. Not sure, yet, whether to add a Nikon body to what is becoming a herd, or buy a Novoflex EOSNIK adapter. The combo would be half the cost of a Canon 50/1.2L, and I want to see what all the fuss over Nikkor is all about.
I saw one of those Canon 50/1.1 or 1.0 lenses, pre-owned, at Houston Camera Exchange. "Expensive" is an understatement!
I dream of a Leica Noctilux, and an M9 to match.
