The 77 was my first premium lens when I got back into photography after a long hiatus.
I didn't really get on the limited bandwagon until early 2012 when I got the 40 prior to a trip to Argentina. That trip really gave me the bug. It was followed by the 15 and 21 in one purchase, then the 70, 31 and 43 fairly soon after, as the Aussie dollar was better than parity with the Greenback at the time.
After a long hard think I let the 40 and 70 go in favour of their older sisters. I have since replaced the 15 for a better copy, and the 43 for a low serial number silver version.
The list was completed in more recent times with the 35, so I have been through them all
