Are you a multi-millionaire (or billionaire) looking for the rarest of Leica lenses to round out your lens collection?
Well, right now there’s an online auction for a Leica lens with a starting bid of CAN$1,038,349.72.
That’s not a typo.
(I placed a bid but then retracted it because I realized I’m at least a million dollars short.)

Now that 50mm APO looks inexpensive!!!
Yes, it does. I guess it’s all relative.
And what makes this 35mm worth that money?
From what I understand, this is the only lens of its kind ever made by Leica.
As for whether it’s worth the money, well…
