My c. 1997 50 'cron (built-in-hood version), LTM CV 50/1.5 and Schneider APO-Symmar 120/5.6 large format lens (plus a bit o' cash) transformed into a Fuji XF 55-200, CV 50/1.5 VM (both new) and an older Fuji-W 125/5.6 (also a large format lens).
I preferred the look of the LTM Nokton over the 'cron (I know, heresy!), but preferred the close focus of the Leica, which is why I got the new 50/1.5 M to replace both of them. I still have a 1997 50/2.8 Elmar if I want a real Leica 50. The two 50's sold for more than the VM Nokton cost, so the extra money helped to fund the XF 55-200.
The older single-coated Fuji large format lens has a much larger image circle than the Schneider, so, even though the Schneider is on paper a higher quality lens (multicoating, more modern construction, more accurate shutter speeds), I'm happy with the older Fuji lens, and I sold the Schneider for about what the Fuji cost me.
