Voigtlander 40/2 Ultron update
The Voigtlander 40/2 Ultron ASPH that I recommended two days ago still is out of stock at B&H, but you can put yourself on the “notify me when in stock” list.
However, it is in stock at Amazon.com @AMAZON through several vendors. Cosina Voigtlander has a tendency to discontinue lenses (like the highly sought-after 125/2.5 APO, still kicking myself on missing that one), so if it has any appeal, I recommend ordering one sometime soon.
