Dave, beautiful shot. lovely colors and very sharp.
Gregg, the drawing styles of both lenses are quite different. I like the bokeh of 1,7 more than 1,4. 1,7 has a beautiful, creamy and gradual blur. I found the 1,7 to have more of the 3Dness than the 1,4.
I'll see if I can post comparative shot using both the lenses. here I'm talking about the C/Y 50mm 1,4 and C/Y 50mm 1,7.
