The best camera is one that still works!
I just watched video #4 Pure Photography #4 and I'd say the guy's obviously focusing the 50/1.8 manually. And there IS a chrome ring around the lens.
The silhouette at the end of the commercial is getting more telling, too...the pentaprism looks great, and classic.
Keeping fingers crossed...
Here's an enhanced still from that #4 video ... still vague but definitely 'very' interesting!
