About a year ago I sold my Leica 560mm f/6.8, thinking at the time that groceries were more important... well a few weeks ago I spotted one on a big auction website that was mounted on the Novoflex quick-focus grip. I was always a fan of the Novoflex squeeze-grip focus, not so much of the Novoflex optics. But, a Leica lens with the Novoflex mount, and a big trip coming up in July? I had to have it

After a month of field use:

Desert Cottontail, Sacramento County California

White-crowned Sparrow, Sacramento County California
The ~12' minimum focus distance is very handy

Cinnamon Teal, Yolo County California

Least Sandpiper, Yolo County California
It's a "keeper".
